7.Description:
(en)TECHNICAL FIELD
The present invention relates to an M2M platform apparatus and a communication service execution method for storing data transmitted from a machine through a communication network and providing an environment for executing a service based on the data.
BACKGROUND ART
In recent years, consideration of M2M (Machine-to-Machine), i.e. inter-machine communication has been in progress in which machines connected to a communication network communicate with each other without intervention of human operation and automatically execute appropriate machine control and the like. For example, in the 3rd Generation Partnership Project (3GPP), standardization of M2M communication standards has been in progress with the term Machine Type Communication (MTC) (e.g. Non-patent Document 1).
Also, in oneM2M (http://www.onem2 m.org/), consideration of M2M use cases, requirements for M2M platforms (M2M-PF), and the like have been in progress. For example, there has been a proposal in which an M2M platform monitors mobility characteristics (such as a moving or stopped state) of each mobile object (machine) such as a commercial vehicle, a truck, or a taxi and changes the range of a paging area for the mobile object based on the monitored mobility characteristics to thereby optimize the number of times a paging signal is transmitted and the intensity thereof in an attempt to reduce the amount of paging signals (e.g. Non-patent Document 2).

Next, an embodiment of the present invention will be described. Note that, in the following description of the drawings, same or similar reference signs denote same or similar elements and portions. In addition, it should be noted that the drawings are schematic and ratios of dimensions and the like are different from actual ones.
Therefore, specific dimensions and the like should be determined in consideration of the following description. Moreover, the drawings also include portions having different dimensional relationships and ratios from each other.
(1) Schematic Overall Configuration of Information Communication System
FIG. 1 is a schematic overall configurational view of an information communication system 10 according to this embodiment. As shown in FIG. 1 , the information communication system 10 includes M2M devices 20 A, 20 B, user equipment 25 , a 3G/LTE infrastructure network 30 , an internal application server 40 , an external application server 50 , and an M2M application middle layer platform apparatus 100 .
The information communication system 10 implements M2M (Machine-to-Machine) in which the M2M devices 20 A, 20 B connected to the 3G/LTE infrastructure network 30 (communication network) communicate with each other without intervention of human operation to allow automatic appropriate control of the M2M devices 20 A, 20 B, automatic provision of information to the user equipment 25 or other components, and the like.
The M2M devices 20 A, 20 B are devices having a communication function for performing inter-machine communication and, in this embodiment, wirelessly connectable to the 3G/LTE infrastructure network 30 . Typical examples of the M2M devices 20 A, 20 B may include communication modules installed on machines (e.g. vehicles, vending machines, and electricity meters) and terminal equipment such as mobile phones.
Note that although only the M2M devices 20 A, 20 B are illustrated in FIG. 1 , a large number of M2M devices can be connected to the 3G/LTE infrastructure network 30 in actual practice. It is also possible to employ a configuration in which a concentrator (M2M-Gateway) configured to bundle a plurality of M2M devices is placed and the M2M devices are connected to the 3G/LTE infrastructure network 30 through the concentrator.
The user equipment 25 (UE) is communication equipment connectable to the 3G/LTE infrastructure network 30 . Examples of the user equipment 25 may include a mobile phone, a smartphone, a tablet, and the like.
The 3G/LTE infrastructure network 30 is a mobile communication network complying with 3G or Long Term Evolution (LTE) technical standards specified by the 3rd Generation Partnership Project (3GPP).
The internal application server 40 and the external application server 50 are connected to the M2M application middle layer platform apparatus 100 . The internal application server 40 and the external application server 50 are capable of communicating with the M2M devices 20 A, 20 B through the 3G/LTE infrastructure network 30 and the M2M application middle layer platform apparatus 100 .
The internal application server 40 is a server on which application programs are executed that are operated by the operating entity of the M2M application middle layer platform apparatus 100 , for example, the operator of the 3G/LTE infrastructure network 30 . Also, the external application server 50 is a server on which application programs are executed that are owned by external entities other than the operating entity of the M2M application middle layer platform apparatus 100 , for example, an electric power company that collects data outputted by M2M devices installed on electricity meters.
The M2M application middle layer platform apparatus 100 is configured to store data transmitted from the M2M devices 20 A, 20 B through the 3G/LTE infrastructure network 30 and provide an environment for executing services based on the data. This embodiment assumes that the M2M application middle layer platform apparatus 100 is operated and managed by the operator of the 3G/LTE infrastructure network 30 . However, the operation and management of the M2M application middle layer platform apparatus 100 are not necessarily have to be done by the operator of the 3G/LTE infrastructure network 30 .
The M2M application middle layer platform apparatus 100 provides a function to optimize services utilizing the data transmitted from the M2M devices 20 A, 20 B and the like while satisfying requirements for M2M platforms (M2M-PF) considered by oneM2M (http://www.onem2m.org/).
(2) Configuration of M2M Platform Apparatus
FIG. 2 is a functional block diagram of the M2M application middle layer platform apparatus 100 . As shown in FIG. 2 , the M2M application middle layer platform apparatus 100 includes a transport layer interface 110 , an application layer gate function 120 , a big data-value-added information repository function unit 200 , and an M2M platform management control function unit 300 .
The transport layer interface 110 is an interface for an infrastructure layer (3G/LTE infrastructure network 30 that provides connectivity to the M2M platform (big data-value-added information repository function unit 200 and M2M platform management control function unit 300 ). It is Gi/SGi and Tsp, which are interfaces for Packet Data Network (PDN), in a case where the system complies with 3GPP MTC specifications (e.g. 3GPP TR 23.682 v11.1.0 Architecture Enhancements to facilitate communications with packet data network and applications R11, Stage 2, June 2012). Note that Gi/SGi is a U-Plane IF, and Tsp is a C-Plane IF.
The transport layer interface 110 has abilities such as an ability to present the M2M platform in a unified manner to a lower infrastructure layer, an ability to abstract various functions of the M2M platform and present only the necessary functions, and an ability to execute authentication on and use the infrastructure layer.
The application layer gate function 120 is an interface between the M2M platform and an application layer. It has abilities such as an ability to present the M2M platform in a unified manner to internal applications 41 , 42 and external applications 51 to 53 , and an ability to bundle interfaces for many application programs.
The application layer gate function 120 also has a function to subject the external applications 51 to 53 to AAA authentication inside the M2M platform in a case where the external applications 51 to 53 are to utilize the M2M platform, and permit access to the M2M platform only for the authenticated application programs. The application layer gate function 120 further has a function to subject the M2M platform side to authentication as gating with the M2M platform in a case where the M2M platform is to start a specific application program.
The internal applications 41 , 42 are application programs implemented in the internal application server 40 and managed by the operating entity of the M2M application middle layer platform apparatus 100 (in this embodiment, the operator of the 3G/LTE infrastructure network 30 ). Examples of these application programs may include application programs related to the locational information on the M2M devices 20 A, 20 B, an intelligent transportation system (ITS), and logistics (e.g. services executable with data which the operator owning the 3G/LTE infrastructure network 30 and the M2M application middle layer platform apparatus 100 can collect itself, more specifically, a customer (user) movement history checking service and the like).
The external applications 51 to 53 are application programs implemented in the external application server 50 and managed by external entities other than the operating entity of the M2M application middle layer platform apparatus 100 . Examples of these application programs may include application programs related to weather information and maps, application programs to be utilized by an electric power company that, as mentioned earlier, collects data outputted by M2M devices installed on electricity meters, and the like.
The M2M application middle layer platform apparatus 100 is capable of executing or starting services which the 3G/LTE infrastructure network 30 has, based on data stored in the big data-value-added information repository function unit 200 (the direction of the arrow “SERVICE EXECUTION” in FIG. 2 ).
The fundamental function of the M2M application middle layer platform apparatus 100 is to gradually develop its big data part with communication performed through a conventional infrastructure network that provides connectivity (the direction of the arrow “DATA REPOSITION” in FIG. 2 ). The big data part is gradually developed in this manner so that more accurate recommendations can be made and applications utilizing the big data can be progressively developed.
In the M2M application middle layer platform apparatus 100 , the “SERVICE EXECUTION” mentioned above, i.e., control from the big data-value-added information repository function unit 200 to the M2M platform management control function unit 300 , and the data reposition from the M2M platform management control function unit 300 to the big data-value-added information repository function unit 200 repeatedly act as if the two side of the same coin. Specifically, communication related to the M2M devices 20 A, 20 B develops the big data stored in the big data-value-added information repository function unit 200 and, based on meaningful data generated as a result thereof, new services or optimized services by the 3G/LTE infrastructure network 30 can be executed or started.
As mentioned above, the M2M application middle layer platform apparatus 100 broadly includes the big data-value-added information repository function unit 200 and the M2M platform management control function unit 300 .
The types of data (information) stored in the big data-value-added information repository function unit 200 include information which the operating entity of the M2M application middle layer platform apparatus 100 can collect itself, information which the operating entity purchases from other entities, information which the operating entity constructs in cooperation with other entities, and the like. More useful and valuable big data can be constructed by taking information related to other entities into the big data-value-added information repository function unit 200 as described above. Consequently, more accurate recommendations can be made.
The M2M platform management control function unit 300 is configured to execute or start services provided by the 3G/LTE infrastructure network 30 , in cooperation with the big data-value-added information repository function unit 200 . The M2M platform management control function unit 300 also provides functions related to security and billing which are necessary in the execution of these services. The M2M platform management control function unit 300 has a non-hierarchical structure and is configured to be flexible to new M2M use cases.
Description will now be given below of details of the functional block configurations of the big data-value-added information repository function unit 200 and the M2M platform management control function unit 300 .
(2.1) Big Data-Value-Added Information Repository Function Unit 200
As shown in FIG. 2 , the big data-value-added information repository function unit 200 includes a data format processing unit 210 , a big data analysis proposal unit 220 , an internal data repository 230 , and an external data repository 240 .
The data format processing unit 210 is configured to determine in which format to store data into the data repository, specifically, the internal data repository 230 or the external data repository 240 . Specifically, the data format processing unit 210 has a function to convert the data transmitted by the M2M devices 20 A, 20 B into desirable formats or into a unified format when the data are taken and stored into the data repository. With this data adaptation performed by the data format processing unit 210 , the formats of the data stored in the data repository are unified.
The big data analysis proposal unit 220 is configured to analyze data stored in the data repository (internal data repository 230 or external data repository 240 ) and, based on the data, propose the content of a service to be executed. Specifically, the big data analysis proposal unit 220 extracts meaningful information from the big data stored in the data repository, analyzes it, and proposes the content of a service which the 2M platform management control function unit 300 should be instructed to execute (the arrow of “SERVICE EXECUTION” in FIG. 2 ).
The big data analysis proposal unit 220 is further configured to instruct the M2M platform management control function unit 300 based on the result of this data analysis to start a service which can be provided by the 3G/LTE infrastructure network 30 .
The internal data repository 230 and the external data repository 240 are configured to store the data transmitted from the M2M devices 20 A, 20 B through the 3G/LTE infrastructure network 30 .
The internal data repository 230 includes a group of data (information) which the operating entity of the M2M application middle layer platform apparatus 100 can collect itself and store, and the like. As shown in FIG. 2 , examples of this group of data may include the preference of the users of the 3G/LTE infrastructure network 30 in terms of communication (user preference), the locational information on the users (mobile communication terminals), information from an intelligent transportation system (ITS) (such as traffic congestion information and regulatory information), information from a logistics system (information which the operator can collect itself, the frequency of communication, the location of communication, the number of terminals, the locational information on the users), and the like.
The external data repository 240 includes a group of data (information) which the operating entity of the M2M application middle layer platform apparatus 100 purchases from other entities and develops in cooperation with other entities. As shown in FIG. 2 , examples of this group of data may include, as mentioned above, weather information, information related to maps, information on electricity amounts outputted by M2M devices installed on electricity meters, and the like. In consideration of its possible future expansion, the external data repository 240 is configured such that the database variations can be additionally increased.
(2.2) M2M Platform Management Control Function Unit 300
As shown in FIG. 2 , the M2M platform management control function unit 300 includes a device control unit 310 , a rule-policy management unit 320 , a security processing unit 330 , a legacy service processing unit 340 , a service billing unit 350 , and a service execution-start unit 360 .
The device control unit 310 is configured to control the M2M devices 20 A, 20 B. Specifically, the device control unit 310 recognizes allowance or disallowance of communication with the M2M devices 20 A, 20 B and the presence or absence of connectivity.
The rule-policy management unit 320 is configured to manage rules or policies for the handling of data to be stored into the data repository (internal data repository 230 or external data repository 240 ). The rule-policy management unit 320 is also configured to cause the data transmitted from the M2M devices 20 A, 20 B to be stored into the data repository based on the rules or policies for the handling of the data to be stored into the data repository (see the arrow of “DATA REPOSITION” in FIG. 2 ).
More specifically, the rule-policy management unit 320 holds rules or policies for the handling of data related to the external applications 51 to 53 utilized by the external entities other than the operating entity of the M2M application middle layer platform apparatus 100 , and causes data that satisfy the held rules or policies to be stored into the data repository. That is, the data transmitted by the M2M devices 20 A, 20 B toward the external applications 51 to 53 sometimes contain data that can be utilized and data that cannot be utilized due to arrangements with the entities (such as companies) that manage the external applications and agreements with these entities, and rules or policies are therefore needed for the data utilization in this situation.
Note that a rule represents the content of a specific arrangement for the utilization of the corresponding data, while a policy is a higher-level concept than the rule and represents a course of utilization of the data. For example, a rule specifically identifies the M2M devices or communication equipment for which to execute the service proposed by the big data analysis proposal unit 220 based on the result of analysis on the corresponding data, while a policy determines whether to allow or disallow the data utilization in accordance with the data type and specifies the type of the control-target M2M devices or communication equipment.
The security processing unit 330 provides functions for entire security processing that is necessary in the M2M platform. Specifically, the security processing unit 330 executes service level authentication, application level authentication, access authentication to a profile and the data repository, and the like which are necessary to start an application related to a specific service. The security processing unit 330 also executes functions such as a function to subject the internal applications 41 , 42 , the external applications 51 to 53 , or the like to authentication or a confidentiality process when these applications utilize the M2M application middle layer platform apparatus 100 , and a function to cause the M2M application middle layer platform apparatus 100 to subject the 3G/LTE infrastructure network 30 to authentication when the 3G/LTE infrastructure network 30 utilizes a function inside the M2M application middle layer platform apparatus 100 .
The legacy service processing unit 340 provides functions necessary to start legacy services, specifically, services of the infrastructure layer (such as a short message service (SMS), voice call, and data communication). More specifically, the legacy service processing unit 340 provides functions to start services situated at higher to lower levels than the transport layer interface 110 (Gi/SGi).
For example, data from a M2M device that transmits data on a patient's pulse rate is analyzed and, when the pulse rate reaches or exceeds a preset value, the legacy service processing unit 340 starts a process of transmitting an SMS message indicating that the patient's pulse rate has reached or exceeded the preset value to particular communication equipment (e.g. the doctor's user equipment 25 ). Note that specific examples as above will be further described later.
The service billing unit 350 provides general functions related to billing involved in the utilization of the M2M application middle layer platform apparatus 100 .
The service execution-start unit 360 is configured to request control on the M2M devices or the user equipment 25 connected through the 3G/LTE infrastructure network 30 , based on the service execution instruction from the big data-value-added information repository function unit 200 . Specifically, based on the content of the service proposed by the big data analysis proposal unit 220 , the service execution-start unit 360 requests the device control unit 310 and the legacy service processing unit 340 to control the corresponding M2M devices or the user equipment 25 . Also, based on the content of the service, the service execution-start unit 360 requests the service billing unit 350 to perform a billing process.
Note that as mentioned above, the M2M platform management control function unit 300 includes the device control unit 310 , the rule-policy management unit 320 , the security processing unit 330 , the legacy service processing unit 340 , the service billing unit 350 , and the service execution-start unit 360 . While these are the main functions, new functional blocks may be added later when new services are devised. Even in this case, new functional blocks can be easily added to the M2M application middle layer platform apparatus 100 . Thus, the M2M platform can be progressively developed.
(3) Operation of M2M Platform Apparatus
The operation of the M2M application middle layer platform apparatus 100 will now be described. Specifically, description will be given of operations in (3.1) acquisition and storage of data from M2M devices, (3.2) starting of a service based on stored data, and (3.3) storage of data in compliance with rules or policies.
(3.1) Acquisition and Storage of Data from M2M Devices
FIG. 3 shows an operation flow in the acquisition and storage of data from the M2M devices. As shown in FIG. 3 , the M2M application middle layer platform apparatus 100 acquires the data transmitted from the M2M devices 20 A, 20 B (S 10 ). Specifically, the M2M application middle layer platform apparatus 100 acquires the data transmitted from the M2M devices 20 A, 20 B to the internal application server 40 or the external application server 50 through the 3G/LTE infrastructure network 30 .
The M2M application middle layer platform apparatus 100 determines in which format to store the data into the big data-value-added information repository function unit 200 (S 20 ). Specifically, the M2M application middle layer platform apparatus 100 determines in which format to store the data into the internal data repository 230 or the external data repository 240 under the assumption that data formats differing by application should be converted into a unified format so that data can be easily analyzed and semantic data can be easily found.
The M2M application middle layer platform apparatus 100 stores the data acquired in Step S 10 into the internal data repository 230 or the external data repository 240 in the determined storage format (S 30 ).
By repeating the operations in Steps S 10 to S 30 , the M2M application middle layer platform apparatus 100 constructs more useful and valuable big data.
(3.2) Starting of Service Based on Stored Data
FIG. 4 shows an operation flow in the starting of a service based on stored data. As shown in FIG. 4 , the M2M application middle layer platform apparatus 100 analyzes data stored in the big data-value-added information repository function unit 200 (S 110 ). Specifically, the M2M application middle layer platform apparatus 100 analyzes data stored in the internal data repository 230 or the external data repository 240 and determines the presence or absence of a recommendation to any M2M device or the user equipment 25 connected to the 3G/LTE infrastructure network 30 .
The M2M application middle layer platform apparatus 100 creates a recommendation condition to the M2M device or the user equipment 25 based on the result of the analysis on the data stored in the internal data repository 230 or the external data repository 240 (S 120 ).
For example, the M2M application middle layer platform apparatus 100 can analyze data from an M2M device that transmits data on a patient's pulse rate and, when the pulse rate reaches or exceeds a preset value, transmit an SMS (recommendation) message indicating that the patient's pulse rate has reached or exceeded the preset value to particular communication equipment (e.g. the doctor's user equipment 25 ). Alternatively, the M2M application middle layer platform apparatus 100 can introduce (recommend) an optimal route to a destination taking the weather into consideration, based on the ITS information stored in the internal data repository 230 and the weather and map information stored in the external data repository 240 .
Based on the recommendation condition thus created, the M2M application middle layer platform apparatus 100 determines whether or not the data stored in the internal data repository 230 or the external data repository 240 satisfies the recommendation condition (S 130 ).
If the stored data satisfies the recommendation condition, the M2M application middle layer platform apparatus 100 , specifically, the big data analysis proposal unit 220 included in the big data-value-added information repository function unit 200 transmits a service start (execution) request based on the recommendation condition to the M2M platform management control function unit 300 (S 140 ).
The M2M platform management control function unit 300 , specifically, the service execution-start unit 360 starts the corresponding service based on the service start request transmitted from the big data-value-added information repository function unit 200 (S 150 ).
For example, the service execution-start unit 360 can request the legacy service processing unit 340 to transmit an SMS message indicating that the patient's pulse rate has reached or exceeded the preset value or instruct a lower layer to cause particular medical equipment to automatically operate in cooperation with the device control unit 310 .
(3.3) Storage of Data in Compliance with Rules or Policies
FIG. 5 shows an operation flow in the storage of data in compliance with rules or policies. As shown in FIG. 5 , the M2M application middle layer platform apparatus 100 acquires the data transmitted from the M2M devices 20 A, 20 B toward the external application server 50 (external application 51 to 53 ) (S 210 ). Examples of the data transmitted toward the external application may include data indicating the amount of electricity used and transmitted to an application program utilized by an electric power company that collects data outputted from M2M devices installed on electricity meters, as mentioned above, and the like.
The M2M application middle layer platform apparatus 100 refers to the rules or policies for the storage and utilization of the acquired data (S 220 ). Specifically, the M2M application middle layer platform apparatus 100 determines, for example, the method of storing the data by referring the rules or policies for the storage and utilization of the data which are managed by the rule-policy management unit 320 .
For example, in the case of the data mentioned above indicating the amount of electricity used, the method of storing the data is determined based on rules or policies such as not storing the specific location where the M2M device having transmitted the data is installed (its address or longitude-latitude information) but storing information on the area where the M2M device is installed (such as its city), and not storing the specific amount of electricity used but storing information indicating whether the amount of electricity used is large or small.
The M2M application middle layer platform apparatus 100 stores the data acquired in Step S 210 into the external data repository 240 in accordance with the data storage method determined in accordance with the rules or policies for the storage and utilization of the data which are managed by the rule-policy management unit 320 (S 230 ).
Note that in the case of the data mentioned above indicating the amount of electricity used, semantic data such as a region (special) or temporal distribution of power consumption can be extracted by analyzing the data that is in compliance with the rules or policies. In this way, a recommendation condition based on the semantic data (e.g. transmitting a message recommending energy saving during a certain time period) or the like can be created.

As mentioned above, the M2M application middle layer platform apparatus 100 includes: the data repositories (internal data repository 230 and external data repository 240 ) configured to store data transmitted from the M2M devices 20 A, 20 B through the 3G/LTE infrastructure network 30 ; the data format processing unit 210 configured to determine in which format to store the data into the data repositories; the big data analysis proposal unit 220 configured to analyze the data stored in the data repositories and, based on the data, propose the content of a service to be executed; the service execution-start unit 360 configured to request control on the M2M devices or the user equipment 25 , based on the content of the service proposed; and the rule-policy management unit 320 configured to cause the data to be stored into the data repositories based on rules or policies for the handling of the data to be stored into the data repositories.
According to this configuration, big data that can potentially be a future source of profit for the operating entity of the M2M application middle layer platform apparatus 100 can be constructed and progressively developed via the connectivity to the 3G/LTE infrastructure network 30 . Moreover, according to the configuration, the operating entity of the M2M application middle layer platform apparatus 100 can provide a value creation service from the profit structure that is based on the provision of the connectivity. This can contribute to creation of more accurate recommending services as well as new services and markets based on information the operating entity collects and analyzes itself. In sum, by effectively utilizing data generated by M2M communication, the application middle layer platform apparatus 100 can timely execute an optimal service based on the data.
Note that it is difficult to instantly build a solid M2M platform and big data, for which reason the M2M application middle layer platform apparatus 100 is configured to be capable of gradually developing an M2M platform and big data step by step. Specifically, the M2M application middle layer platform apparatus 100 is configured such that services which can be initiated early can be implemented early, and is considered such that big data can be progressively developed by gradually taking in data managed by other entities (such as companies) and the like.
In this embodiment, the M2M application middle layer platform apparatus 100 is functionally separated completely from the 3G/LTE infrastructure network 30 by the transport layer interface 110 . Hence, an M2M platform architecture with no overlap with the 3G/LTE function can be easily realized. Further, in this embodiment, the M2M application middle layer platform apparatus 100 includes the legacy service processing unit 340 and can therefore effectively utilize an existing communication infrastructure and also easily migrate to a new communication infrastructure in the future.
Also, in this embodiment, the execution and starting of services occur from the M2M application middle layer platform apparatus 100 to the 3G/LTE infrastructure network 30 , which can promote the utilization of services provided by the 3G/LTE infrastructure network 30 .

BACKGROUND ART
In recent years, consideration of M2M (Machine-to-Machine), i.e. inter-machine communication has been in progress in which machines connected to a communication network communicate with each other without intervention of human operation and automatically execute appropriate machine control and the like. For example, in the 3rd Generation Partnership Project (3GPP), standardization of M2M communication standards has been in progress with the term Machine Type Communication (MTC) (e.g. Non-patent Document 1).
Also, in oneM2M (http://www.onem2 m.org/), consideration of M2M use cases, requirements for M2M platforms (M2M-PF), and the like have been in progress. For example, there has been a proposal in which an M2M platform monitors mobility characteristics (such as a moving or stopped state) of each mobile object (machine) such as a commercial vehicle, a truck, or a taxi and changes the range of a paging area for the mobile object based on the monitored mobility characteristics to thereby optimize the number of times a paging signal is transmitted and the intensity thereof in an attempt to reduce the amount of paging signals (e.g. Non-patent Document 2).

MODES FOR CARRYING OUT THE INVENTION
Next, an embodiment of the present invention will be described. Note that, in the following description of the drawings, same or similar reference signs denote same or similar elements and portions. In addition, it should be noted that the drawings are schematic and ratios of dimensions and the like are different from actual ones.
Therefore, specific dimensions and the like should be determined in consideration of the following description. Moreover, the drawings also include portions having different dimensional relationships and ratios from each other.
(1) Schematic Overall Configuration of Information Communication System
FIG. 1 is a schematic overall configurational view of an information communication system 10 according to this embodiment. As shown in FIG. 1 , the information communication system 10 includes M2M devices 20 A, 20 B, user equipment 25 , a 3G/LTE infrastructure network 30 , an internal application server 40 , an external application server 50 , and an M2M application middle layer platform apparatus 100 .
The information communication system 10 implements M2M (Machine-to-Machine) in which the M2M devices 20 A, 20 B connected to the 3G/LTE infrastructure network 30 (communication network) communicate with each other without intervention of human operation to allow automatic appropriate control of the M2M devices 20 A, 20 B, automatic provision of information to the user equipment 25 or other components, and the like.
The M2M devices 20 A, 20 B are devices having a communication function for performing inter-machine communication and, in this embodiment, wirelessly connectable to the 3G/LTE infrastructure network 30 . Typical examples of the M2M devices 20 A, 20 B may include communication modules installed on machines (e.g. vehicles, vending machines, and electricity meters) and terminal equipment such as mobile phones.
Note that although only the M2M devices 20 A, 20 B are illustrated in FIG. 1 , a large number of M2M devices can be connected to the 3G/LTE infrastructure network 30 in actual practice. It is also possible to employ a configuration in which a concentrator (M2M-Gateway) configured to bundle a plurality of M2M devices is placed and the M2M devices are connected to the 3G/LTE infrastructure network 30 through the concentrator.
The user equipment 25 (UE) is communication equipment connectable to the 3G/LTE infrastructure network 30 . Examples of the user equipment 25 may include a mobile phone, a smartphone, a tablet, and the like.
The 3G/LTE infrastructure network 30 is a mobile communication network complying with 3G or Long Term Evolution (LTE) technical standards specified by the 3rd Generation Partnership Project (3GPP).
The internal application server 40 and the external application server 50 are connected to the M2M application middle layer platform apparatus 100 . The internal application server 40 and the external application server 50 are capable of communicating with the M2M devices 20 A, 20 B through the 3G/LTE infrastructure network 30 and the M2M application middle layer platform apparatus 100 .
The internal application server 40 is a server on which application programs are executed that are operated by the operating entity of the M2M application middle layer platform apparatus 100 , for example, the operator of the 3G/LTE infrastructure network 30 . Also, the external application server 50 is a server on which application programs are executed that are owned by external entities other than the operating entity of the M2M application middle layer platform apparatus 100 , for example, an electric power company that collects data outputted by M2M devices installed on electricity meters.
The M2M application middle layer platform apparatus 100 is configured to store data transmitted from the M2M devices 20 A, 20 B through the 3G/LTE infrastructure network 30 and provide an environment for executing services based on the data. This embodiment assumes that the M2M application middle layer platform apparatus 100 is operated and managed by the operator of the 3G/LTE infrastructure network 30 . However, the operation and management of the M2M application middle layer platform apparatus 100 are not necessarily have to be done by the operator of the 3G/LTE infrastructure network 30 .
The M2M application middle layer platform apparatus 100 provides a function to optimize services utilizing the data transmitted from the M2M devices 20 A, 20 B and the like while satisfying requirements for M2M platforms (M2M-PF) considered by oneM2M (http://www.onem2m.org/).
(2) Configuration of M2M Platform Apparatus
FIG. 2 is a functional block diagram of the M2M application middle layer platform apparatus 100 . As shown in FIG. 2 , the M2M application middle layer platform apparatus 100 includes a transport layer interface 110 , an application layer gate function 120 , a big data-value-added information repository function unit 200 , and an M2M platform management control function unit 300 .
The transport layer interface 110 is an interface for an infrastructure layer (3G/LTE infrastructure network 30 that provides connectivity to the M2M platform (big data-value-added information repository function unit 200 and M2M platform management control function unit 300 ). It is Gi/SGi and Tsp, which are interfaces for Packet Data Network (PDN), in a case where the system complies with 3GPP MTC specifications (e.g. 3GPP TR 23.682 v11.1.0 Architecture Enhancements to facilitate communications with packet data network and applications R11, Stage 2, June 2012). Note that Gi/SGi is a U-Plane IF, and Tsp is a C-Plane IF.
The transport layer interface 110 has abilities such as an ability to present the M2M platform in a unified manner to a lower infrastructure layer, an ability to abstract various functions of the M2M platform and present only the necessary functions, and an ability to execute authentication on and use the infrastructure layer.
The application layer gate function 120 is an interface between the M2M platform and an application layer. It has abilities such as an ability to present the M2M platform in a unified manner to internal applications 41 , 42 and external applications 51 to 53 , and an ability to bundle interfaces for many application programs.
The application layer gate function 120 also has a function to subject the external applications 51 to 53 to AAA authentication inside the M2M platform in a case where the external applications 51 to 53 are to utilize the M2M platform, and permit access to the M2M platform only for the authenticated application programs. The application layer gate function 120 further has a function to subject the M2M platform side to authentication as gating with the M2M platform in a case where the M2M platform is to start a specific application program.
The internal applications 41 , 42 are application programs implemented in the internal application server 40 and managed by the operating entity of the M2M application middle layer platform apparatus 100 (in this embodiment, the operator of the 3G/LTE infrastructure network 30 ). Examples of these application programs may include application programs related to the locational information on the M2M devices 20 A, 20 B, an intelligent transportation system (ITS), and logistics (e.g. services executable with data which the operator owning the 3G/LTE infrastructure network 30 and the M2M application middle layer platform apparatus 100 can collect itself, more specifically, a customer (user) movement history checking service and the like).
The external applications 51 to 53 are application programs implemented in the external application server 50 and managed by external entities other than the operating entity of the M2M application middle layer platform apparatus 100 . Examples of these application programs may include application programs related to weather information and maps, application programs to be utilized by an electric power company that, as mentioned earlier, collects data outputted by M2M devices installed on electricity meters, and the like.
The M2M application middle layer platform apparatus 100 is capable of executing or starting services which the 3G/LTE infrastructure network 30 has, based on data stored in the big data-value-added information repository function unit 200 (the direction of the arrow “SERVICE EXECUTION” in FIG. 2 ).
The fundamental function of the M2M application middle layer platform apparatus 100 is to gradually develop its big data part with communication performed through a conventional infrastructure network that provides connectivity (the direction of the arrow “DATA REPOSITION” in FIG. 2 ). The big data part is gradually developed in this manner so that more accurate recommendations can be made and applications utilizing the big data can be progressively developed.
In the M2M application middle layer platform apparatus 100 , the “SERVICE EXECUTION” mentioned above, i.e., control from the big data-value-added information repository function unit 200 to the M2M platform management control function unit 300 , and the data reposition from the M2M platform management control function unit 300 to the big data-value-added information repository function unit 200 repeatedly act as if the two side of the same coin. Specifically, communication related to the M2M devices 20 A, 20 B develops the big data stored in the big data-value-added information repository function unit 200 and, based on meaningful data generated as a result thereof, new services or optimized services by the 3G/LTE infrastructure network 30 can be executed or started.
As mentioned above, the M2M application middle layer platform apparatus 100 broadly includes the big data-value-added information repository function unit 200 and the M2M platform management control function unit 300 .
The types of data (information) stored in the big data-value-added information repository function unit 200 include information which the operating entity of the M2M application middle layer platform apparatus 100 can collect itself, information which the operating entity purchases from other entities, information which the operating entity constructs in cooperation with other entities, and the like. More useful and valuable big data can be constructed by taking information related to other entities into the big data-value-added information repository function unit 200 as described above. Consequently, more accurate recommendations can be made.
The M2M platform management control function unit 300 is configured to execute or start services provided by the 3G/LTE infrastructure network 30 , in cooperation with the big data-value-added information repository function unit 200 . The M2M platform management control function unit 300 also provides functions related to security and billing which are necessary in the execution of these services. The M2M platform management control function unit 300 has a non-hierarchical structure and is configured to be flexible to new M2M use cases.
Description will now be given below of details of the functional block configurations of the big data-value-added information repository function unit 200 and the M2M platform management control function unit 300 .
(2.1) Big Data-Value-Added Information Repository Function Unit 200
As shown in FIG. 2 , the big data-value-added information repository function unit 200 includes a data format processing unit 210 , a big data analysis proposal unit 220 , an internal data repository 230 , and an external data repository 240 .
The data format processing unit 210 is configured to determine in which format to store data into the data repository, specifically, the internal data repository 230 or the external data repository 240 . Specifically, the data format processing unit 210 has a function to convert the data transmitted by the M2M devices 20 A, 20 B into desirable formats or into a unified format when the data are taken and stored into the data repository. With this data adaptation performed by the data format processing unit 210 , the formats of the data stored in the data repository are unified.
The big data analysis proposal unit 220 is configured to analyze data stored in the data repository (internal data repository 230 or external data repository 240 ) and, based on the data, propose the content of a service to be executed. Specifically, the big data analysis proposal unit 220 extracts meaningful information from the big data stored in the data repository, analyzes it, and proposes the content of a service which the 2M platform management control function unit 300 should be instructed to execute (the arrow of “SERVICE EXECUTION” in FIG. 2 ).
The big data analysis proposal unit 220 is further configured to instruct the M2M platform management control function unit 300 based on the result of this data analysis to start a service which can be provided by the 3G/LTE infrastructure network 30 .
The internal data repository 230 and the external data repository 240 are configured to store the data transmitted from the M2M devices 20 A, 20 B through the 3G/LTE infrastructure network 30 .
The internal data repository 230 includes a group of data (information) which the operating entity of the M2M application middle layer platform apparatus 100 can collect itself and store, and the like. As shown in FIG. 2 , examples of this group of data may include the preference of the users of the 3G/LTE infrastructure network 30 in terms of communication (user preference), the locational information on the users (mobile communication terminals), information from an intelligent transportation system (ITS) (such as traffic congestion information and regulatory information), information from a logistics system (information which the operator can collect itself, the frequency of communication, the location of communication, the number of terminals, the locational information on the users), and the like.
The external data repository 240 includes a group of data (information) which the operating entity of the M2M application middle layer platform apparatus 100 purchases from other entities and develops in cooperation with other entities. As shown in FIG. 2 , examples of this group of data may include, as mentioned above, weather information, information related to maps, information on electricity amounts outputted by M2M devices installed on electricity meters, and the like. In consideration of its possible future expansion, the external data repository 240 is configured such that the database variations can be additionally increased.
(2.2) M2M Platform Management Control Function Unit 300
As shown in FIG. 2 , the M2M platform management control function unit 300 includes a device control unit 310 , a rule-policy management unit 320 , a security processing unit 330 , a legacy service processing unit 340 , a service billing unit 350 , and a service execution-start unit 360 .
The device control unit 310 is configured to control the M2M devices 20 A, 20 B. Specifically, the device control unit 310 recognizes allowance or disallowance of communication with the M2M devices 20 A, 20 B and the presence or absence of connectivity.
The rule-policy management unit 320 is configured to manage rules or policies for the handling of data to be stored into the data repository (internal data repository 230 or external data repository 240 ). The rule-policy management unit 320 is also configured to cause the data transmitted from the M2M devices 20 A, 20 B to be stored into the data repository based on the rules or policies for the handling of the data to be stored into the data repository (see the arrow of “DATA REPOSITION” in FIG. 2 ).
More specifically, the rule-policy management unit 320 holds rules or policies for the handling of data related to the external applications 51 to 53 utilized by the external entities other than the operating entity of the M2M application middle layer platform apparatus 100 , and causes data that satisfy the held rules or policies to be stored into the data repository. That is, the data transmitted by the M2M devices 20 A, 20 B toward the external applications 51 to 53 sometimes contain data that can be utilized and data that cannot be utilized due to arrangements with the entities (such as companies) that manage the external applications and agreements with these entities, and rules or policies are therefore needed for the data utilization in this situation.
Note that a rule represents the content of a specific arrangement for the utilization of the corresponding data, while a policy is a higher-level concept than the rule and represents a course of utilization of the data. For example, a rule specifically identifies the M2M devices or communication equipment for which to execute the service proposed by the big data analysis proposal unit 220 based on the result of analysis on the corresponding data, while a policy determines whether to allow or disallow the data utilization in accordance with the data type and specifies the type of the control-target M2M devices or communication equipment.
The security processing unit 330 provides functions for entire security processing that is necessary in the M2M platform. Specifically, the security processing unit 330 executes service level authentication, application level authentication, access authentication to a profile and the data repository, and the like which are necessary to start an application related to a specific service. The security processing unit 330 also executes functions such as a function to subject the internal applications 41 , 42 , the external applications 51 to 53 , or the like to authentication or a confidentiality process when these applications utilize the M2M application middle layer platform apparatus 100 , and a function to cause the M2M application middle layer platform apparatus 100 to subject the 3G/LTE infrastructure network 30 to authentication when the 3G/LTE infrastructure network 30 utilizes a function inside the M2M application middle layer platform apparatus 100 .
The legacy service processing unit 340 provides functions necessary to start legacy services, specifically, services of the infrastructure layer (such as a short message service (SMS), voice call, and data communication). More specifically, the legacy service processing unit 340 provides functions to start services situated at higher to lower levels than the transport layer interface 110 (Gi/SGi).
For example, data from a M2M device that transmits data on a patient's pulse rate is analyzed and, when the pulse rate reaches or exceeds a preset value, the legacy service processing unit 340 starts a process of transmitting an SMS message indicating that the patient's pulse rate has reached or exceeded the preset value to particular communication equipment (e.g. the doctor's user equipment 25 ). Note that specific examples as above will be further described later.
The service billing unit 350 provides general functions related to billing involved in the utilization of the M2M application middle layer platform apparatus 100 .
The service execution-start unit 360 is configured to request control on the M2M devices or the user equipment 25 connected through the 3G/LTE infrastructure network 30 , based on the service execution instruction from the big data-value-added information repository function unit 200 . Specifically, based on the content of the service proposed by the big data analysis proposal unit 220 , the service execution-start unit 360 requests the device control unit 310 and the legacy service processing unit 340 to control the corresponding M2M devices or the user equipment 25 . Also, based on the content of the service, the service execution-start unit 360 requests the service billing unit 350 to perform a billing process.
Note that as mentioned above, the M2M platform management control function unit 300 includes the device control unit 310 , the rule-policy management unit 320 , the security processing unit 330 , the legacy service processing unit 340 , the service billing unit 350 , and the service execution-start unit 360 . While these are the main functions, new functional blocks may be added later when new services are devised. Even in this case, new functional blocks can be easily added to the M2M application middle layer platform apparatus 100 . Thus, the M2M platform can be progressively developed.
(3) Operation of M2M Platform Apparatus
The operation of the M2M application middle layer platform apparatus 100 will now be described. Specifically, description will be given of operations in (3.1) acquisition and storage of data from M2M devices, (3.2) starting of a service based on stored data, and (3.3) storage of data in compliance with rules or policies.
(3.1) Acquisition and Storage of Data from M2M Devices
FIG. 3 shows an operation flow in the acquisition and storage of data from the M2M devices. As shown in FIG. 3 , the M2M application middle layer platform apparatus 100 acquires the data transmitted from the M2M devices 20 A, 20 B (S 10 ). Specifically, the M2M application middle layer platform apparatus 100 acquires the data transmitted from the M2M devices 20 A, 20 B to the internal application server 40 or the external application server 50 through the 3G/LTE infrastructure network 30 .
The M2M application middle layer platform apparatus 100 determines in which format to store the data into the big data-value-added information repository function unit 200 (S 20 ). Specifically, the M2M application middle layer platform apparatus 100 determines in which format to store the data into the internal data repository 230 or the external data repository 240 under the assumption that data formats differing by application should be converted into a unified format so that data can be easily analyzed and semantic data can be easily found.
The M2M application middle layer platform apparatus 100 stores the data acquired in Step S 10 into the internal data repository 230 or the external data repository 240 in the determined storage format (S 30 ).
By repeating the operations in Steps S 10 to S 30 , the M2M application middle layer platform apparatus 100 constructs more useful and valuable big data.
(3.2) Starting of Service Based on Stored Data
FIG. 4 shows an operation flow in the starting of a service based on stored data. As shown in FIG. 4 , the M2M application middle layer platform apparatus 100 analyzes data stored in the big data-value-added information repository function unit 200 (S 110 ). Specifically, the M2M application middle layer platform apparatus 100 analyzes data stored in the internal data repository 230 or the external data repository 240 and determines the presence or absence of a recommendation to any M2M device or the user equipment 25 connected to the 3G/LTE infrastructure network 30 .
The M2M application middle layer platform apparatus 100 creates a recommendation condition to the M2M device or the user equipment 25 based on the result of the analysis on the data stored in the internal data repository 230 or the external data repository 240 (S 120 ).
For example, the M2M application middle layer platform apparatus 100 can analyze data from an M2M device that transmits data on a patient's pulse rate and, when the pulse rate reaches or exceeds a preset value, transmit an SMS (recommendation) message indicating that the patient's pulse rate has reached or exceeded the preset value to particular communication equipment (e.g. the doctor's user equipment 25 ). Alternatively, the M2M application middle layer platform apparatus 100 can introduce (recommend) an optimal route to a destination taking the weather into consideration, based on the ITS information stored in the internal data repository 230 and the weather and map information stored in the external data repository 240 .
Based on the recommendation condition thus created, the M2M application middle layer platform apparatus 100 determines whether or not the data stored in the internal data repository 230 or the external data repository 240 satisfies the recommendation condition (S 130 ).
If the stored data satisfies the recommendation condition, the M2M application middle layer platform apparatus 100 , specifically, the big data analysis proposal unit 220 included in the big data-value-added information repository function unit 200 transmits a service start (execution) request based on the recommendation condition to the M2M platform management control function unit 300 (S 140 ).
The M2M platform management control function unit 300 , specifically, the service execution-start unit 360 starts the corresponding service based on the service start request transmitted from the big data-value-added information repository function unit 200 (S 150 ).
For example, the service execution-start unit 360 can request the legacy service processing unit 340 to transmit an SMS message indicating that the patient's pulse rate has reached or exceeded the preset value or instruct a lower layer to cause particular medical equipment to automatically operate in cooperation with the device control unit 310 .
(3.3) Storage of Data in Compliance with Rules or Policies
FIG. 5 shows an operation flow in the storage of data in compliance with rules or policies. As shown in FIG. 5 , the M2M application middle layer platform apparatus 100 acquires the data transmitted from the M2M devices 20 A, 20 B toward the external application server 50 (external application 51 to 53 ) (S 210 ). Examples of the data transmitted toward the external application may include data indicating the amount of electricity used and transmitted to an application program utilized by an electric power company that collects data outputted from M2M devices installed on electricity meters, as mentioned above, and the like.
The M2M application middle layer platform apparatus 100 refers to the rules or policies for the storage and utilization of the acquired data (S 220 ). Specifically, the M2M application middle layer platform apparatus 100 determines, for example, the method of storing the data by referring the rules or policies for the storage and utilization of the data which are managed by the rule-policy management unit 320 .
For example, in the case of the data mentioned above indicating the amount of electricity used, the method of storing the data is determined based on rules or policies such as not storing the specific location where the M2M device having transmitted the data is installed (its address or longitude-latitude information) but storing information on the area where the M2M device is installed (such as its city), and not storing the specific amount of electricity used but storing information indicating whether the amount of electricity used is large or small.
The M2M application middle layer platform apparatus 100 stores the data acquired in Step S 210 into the external data repository 240 in accordance with the data storage method determined in accordance with the rules or policies for the storage and utilization of the data which are managed by the rule-policy management unit 320 (S 230 ).
Note that in the case of the data mentioned above indicating the amount of electricity used, semantic data such as a region (special) or temporal distribution of power consumption can be extracted by analyzing the data that is in compliance with the rules or policies. In this way, a recommendation condition based on the semantic data (e.g. transmitting a message recommending energy saving during a certain time period) or the like can be created.
(4) Advantageous Effects
As mentioned above, the M2M application middle layer platform apparatus 100 includes: the data repositories (internal data repository 230 and external data repository 240 ) configured to store data transmitted from the M2M devices 20 A, 20 B through the 3G/LTE infrastructure network 30 ; the data format processing unit 210 configured to determine in which format to store the data into the data repositories; the big data analysis proposal unit 220 configured to analyze the data stored in the data repositories and, based on the data, propose the content of a service to be executed; the service execution-start unit 360 configured to request control on the M2M devices or the user equipment 25 , based on the content of the service proposed; and the rule-policy management unit 320 configured to cause the data to be stored into the data repositories based on rules or policies for the handling of the data to be stored into the data repositories.
According to this configuration, big data that can potentially be a future source of profit for the operating entity of the M2M application middle layer platform apparatus 100 can be constructed and progressively developed via the connectivity to the 3G/LTE infrastructure network 30 . Moreover, according to the configuration, the operating entity of the M2M application middle layer platform apparatus 100 can provide a value creation service from the profit structure that is based on the provision of the connectivity. This can contribute to creation of more accurate recommending services as well as new services and markets based on information the operating entity collects and analyzes itself. In sum, by effectively utilizing data generated by M2M communication, the application middle layer platform apparatus 100 can timely execute an optimal service based on the data.
Note that it is difficult to instantly build a solid M2M platform and big data, for which reason the M2M application middle layer platform apparatus 100 is configured to be capable of gradually developing an M2M platform and big data step by step. Specifically, the M2M application middle layer platform apparatus 100 is configured such that services which can be initiated early can be implemented early, and is considered such that big data can be progressively developed by gradually taking in data managed by other entities (such as companies) and the like.
In this embodiment, the M2M application middle layer platform apparatus 100 is functionally separated completely from the 3G/LTE infrastructure network 30 by the transport layer interface 110 . Hence, an M2M platform architecture with no overlap with the 3G/LTE function can be easily realized. Further, in this embodiment, the M2M application middle layer platform apparatus 100 includes the legacy service processing unit 340 and can therefore effectively utilize an existing communication infrastructure and also easily migrate to a new communication infrastructure in the future.
Also, in this embodiment, the execution and starting of services occur from the M2M application middle layer platform apparatus 100 to the 3G/LTE infrastructure network 30 , which can promote the utilization of services provided by the 3G/LTE infrastructure network 30 .
