(en)CLAIM OF PRIORITY
This application claims the benefit under 35 U.S.C. §119(a) of a Korean patent application filed on Aug. 14, 2014 in the Korean Intellectual Property Office and assigned Serial number 10-2014-0106060, the entire disclosure of which is hereby incorporated by reference.
TECHNICAL FIELD
The present disclosure relates to electronic devices, and more particularly to a method and apparatus for device positioning.
BACKGROUND
Various types of electronic products have been developed with the development of electronic technology. Recently, portable electronic devices such as smartphones, tablet PCs, and the like are widely used. Such portable electronic devices are so multifunctional as to provide various services, for example, photographing, music playback, video playback, an electronic mail service, a social networking service (SNS), a map service, a bus guide, a subway guide, and the like.
Various services provided by an electronic device may require location information, and the electronic device may provide the location information required for providing services using a positioning means such as a global positioning system (GPS) module. Various positioning technologies recently developed are based on not only the GPS but also wireless fidelity (Wi-Fi), Bluetooth, or the like.
As various electronic devices are widely used, various services are developed to be provided on the basis of a device-to-device network. For example, a peripheral electronic device such as a smartwatch, smart glasses, or the like may interwork with a main electronic device such as a smartphone so as to provide various services.
As described above, an electronic device may obtain location information using a positioning means provided in the electronic device if the location information is required. However, in the case where positioning is not available due to a state or a location of the electronic device, the location information may be unable to be obtained.
A feature of location information (e.g., accuracy, required time, or the like) required for a specific service may vary with service characteristics, but, in the case where the electronic device is provided with a limited positioning means alone, unnecessary power consumption may occur. On the contrary, in the case where the electronic device is provided with various positioning means for obtaining location information suitable for the purpose of a service, the manufacture of the electronic device may not be efficient in terms of cost.
In a situation in which a plurality of electronic devices connected by a network have identical positioning means, the plurality of electronic devices may redundantly perform positioning using the identical positioning means.
SUMMARY
According to aspects of the disclosure, an electronic device is provided comprising: a memory; and one or more processors configured to: assign a first positioning role to the electronic device and a second positioning role to a counterpart device, the counterpart device and the electronic device being part of a communications network, obtain at least one of a location information and a supplemental location information based on the first positioning role and the second positioning role, and detect a location of the electronic device based on the at least one of the location information and supplemental location information.
According to aspects of the disclosure, a method is provided comprising: assigning, by a first electronic device, a first positioning role to the first electronic device and a second positioning role to a second electronic device, wherein the first electronic device and the second electronic device are part of a communications network, obtaining at least one of a location information and a supplemental location information based on the first positioning role and the second positioning role, and detecting a location of the first electronic device based on the least one of the location information and the supplemental location information.
According to aspects of the disclosure, a non-transitory computer-readable recording medium is provided that stores processor-executable instructions which when executed by one or more processors, cause the one or more processors to perform a method comprising: assigning, by a first electronic device, a first positioning role to the first electronic device and a second positioning role to a second electronic device, wherein the first electronic device and the second electronic device are part of a communications network, obtaining at least one of a location information and a supplemental location information based on the first positioning role and the second positioning role, and detecting a location of the first electronic device based on the least one of the location information and the supplemental location information.

FIG. 1 is a diagram illustrating an example of a positioning system, according to various embodiments of the present disclosure.
Referring to FIG. 1 , a positioning system 1000 may include a main electronic device (or a first electronic device) 100 and at least one peripheral electronic device 200 - 1 to 200 - 3 . According to an embodiment of the present disclosure, the main electronic device 100 and the peripheral electronic devices 200 may both be part of a network 10 . For example, the network 10 may have a mesh-type structure in which each of the main electronic device 100 and peripheral electronic devices 200 is connected to each other. For another example, the network 10 may have a star-type structure in which each of the peripheral electronic devices 200 is connected to a central hub, i.e., the main electronic device 100 . The peripheral electronic devices 200 may be located within a communication-enabled distance from the main electronic device 100 .
According to an embodiment of the present disclosure, the main electronic device 100 may be a smartphone. According to an embodiment of the present disclosure, the peripheral electronic devices 200 may be wearable electronic devices. For example, referring to FIG. 1 , a first peripheral electronic device 200 - 1 may be a smart band, a second peripheral electronic device 200 - 1 may be smart glasses, and a third peripheral electronic device 200 - 3 may be a smartwatch. Although FIG. 1 illustrates that a smartphone operates as a main electronic device, one of the peripheral electronic device 200 - 1 to 200 - 3 of FIG. 1 may operate as a main electronic device depending on situations.
According to an embodiment of the present disclosure, the main electronic device 100 and at least one peripheral electronic device 200 - 1 to 200 - 3 may include different types of positioning means and/or positioning information (e.g., location information or supplemental location information). For example, the main electronic device 100 may include a GPS module, a Wi-Fi module, a Bluetooth module, a pedestrian dead-reckoning (PDR) module, and a database of an electronic map of a specific region. The first peripheral electronic device 200 - 1 may include assisted GPS (A-GPS) information. The second peripheral electronic device 200 - 2 may include a visible light communication (VLC) module. The third peripheral electronic device 200 - 3 may include PDR information obtained by various sensors (e.g., an acceleration sensor, an angular velocity sensor, a geomagnetic sensor, or the like).
According to an embodiment of the present disclosure, each of the main electronic device 100 and the peripheral electronic devices 200 may generate a respective positioning profile. The positioning profile of a particular device may include information required for cooperative positioning (positioning through cooperation between a specific electronic device and another electronic device adjacent thereto). According to an embodiment of the present disclosure, the positioning profile may include at least one of positioning means information of an electronic device, location information measured currently or previously by a positioning means, supplemental location information for each positioning means (or, additional location information), current positioning means information of an electronic device, priority information of a positioning means, data synchronization information of an electronic device, data type of location information or supplemental location information, or state information of an electronic device.
The positioning means information represents information on the type of a positioning means (or, a positioning technology) that that is available in each respective electronic device. For example, the positioning means may include at least one of a global navigation satellite system (GNSS) (e.g., GPS), Wi-Fi positioning system (WPS), PDR, cell positioning, VLC positioning, earth's magnetic field positioning, ultrasonic positioning, Bluetooth positioning, infrared (IrDA) positioning, simultaneous localization and mapping (SLAM), ultra-wideband (UWB) positioning, RFID positioning, or fingerprint positioning.
The supplemental location information for each positioning means represents additional information that is unable to be used alone to discern a device's location, but is nonetheless necessary, helpful, or otherwise usable for identifying the device's location by using a particular positioning means. For example, the supplemental location information may include at least one of access point (AP) information, a MAC address, a beacon, time information, network information, traffic information, weather information, advertisement information, information obtained through camera image recognition, map information, map tile information, fingerprint information (Wi-Fi, Bluetooth, magnetic field, ZigBee, or the like), tag information (NFC, RFID, barcode, or the like), values of various sensors (e.g., an acceleration sensor, an angular velocity sensor, a geomagnetic sensor, a gyro sensor, an altitude sensor, or the like), or supplemental satellite navigation information.
The priority information of a positioning means represents a priority order for a plurality of positioning means. According to an embodiment of the present disclosure, this information may include a plurality of pieces of priority information classified according to at least one of accuracy, power consumption, or a time required for positioning. For example, the priority information may include priority information in which positioning means having higher accuracy are given a greater priority that those with comparatively lower accuracy. As another example, the priority information may include priority information in which positioning means having a lower power consumption are given a greater priority than positioning means having a comparatively higher power consumption. As another example, the priority information may include priority information in which positioning means that are capable of determining location faster are granted a higher priority that positioning means that are comparatively slower.
The data synchronization information of an electronic device may include information on a synchronization period or a synchronization time point of various data of the electronic device.
The data type of location information or supplemental location information represents a data type of location information or supplemental location information that may be obtained by an electronic device during a positioning process. For example, the data type of location information or supplemental location information may indicate that location information may be obtained in the form of coordinates or location information may be obtained in the form of a moving direction or a distance traveled such as PDR information. Alternatively, the data type of location information or supplemental location information may indicate that information on a Bluetooth low energy (BLE) beacon around an electronic device received through BLE may be provided as supplemental location information.
The current positioning means information may represent information on current availability of a positioning means included in an electronic device. For example, a positioning means that is unable to be used or is difficult to use due to a current location, a battery state, or a user command may be excluded among positioning means included in an electronic device. The current positioning means information represents information indicating a current state of being unable to be used or difficult to use. A positioning means may be considered difficult to use when it is available for use by a device, but its use by the device would result in the device failing to satisfy a particular power consumption/efficiency goal and/or accuracy goal.
The state information of an electronic device may include information indicating a state or performance of the electronic device such as an on/off state, a sleep/active state, a remaining capacity of a battery, whether or not the battery is charged, processor's performance, memory space, or the like. Furthermore, the state information of an electronic device may include information identifying a set time in the case where a time at which the electronic device is turned on/off or enters a sleep/active mode is set.
The main electronic device 100 may request the peripheral electronic device 200 to send a positioning profile of the peripheral electronic device 200 , and may receive the positioning profile in response. Accordingly, the main electronic device 100 may integrate the positioning profiles of the main electronic device 100 and the peripheral electronic device 200 to manage the positioning profiles.
According to an embodiment of the present disclosure, the main electronic device 100 may transmit its positioning profile to the peripheral electronic device 200 . Accordingly, each of the main electronic device 100 and the peripheral electronic device 200 may share and manage the positioning profiles of all electronic devices.
According to an embodiment of the present disclosure, upon receiving the positioning profile from the peripheral electronic device 200 , the main electronic device 100 may determine whether cooperative positioning is possible on the basis of the positioning profiles of the main electronic device 100 and the peripheral electronic device 200 . If it is determined that cooperative positioning is possible, the positioning profile received from the peripheral electronic device 200 may be stored and managed together with the positioning profile of the main electronic device 100 .
According to an embodiment of the present disclosure, if it is determined that only some of the peripheral electronic devices 200 - 1 to 200 - 3 are available for cooperative positioning, the main electronic device 100 may store and manage only the positioning profiles of only those peripheral electronic devices that are available.
According to an embodiment of the present disclosure, the main electronic device 100 or the peripheral electronic device 200 may transmit/receive the positioning profile after being connected to a network. According to another embodiment of the present disclosure, the main electronic device 100 or the peripheral electronic device 200 may transmit/receive the positioning profile before being connected to a network. For example, the positioning profile may be added to a beacon signal transmitted/received during a network connection process so that the positioning profile is transmitted.
According to an embodiment of the present disclosure, if the positioning profile is changed, the main electronic device 100 or the peripheral electronic device 200 may update the positioning profile. For example, if the positioning profile of the main electronic device 100 is changed or a changed positioning profile is received from the peripheral electronic device 200 , the electronic device 100 may update the positioning profile.
A change in the positioning profile may include, for example, turning on/off of a positioning means by a user, a change in a remaining capacity of a battery, release of a network connection, switching to a sleep mode, a location change of an electronic device, or the like.
According to an embodiment of the present disclosure, if the positioning profile of the device 100 or device 200 is updated, the main electronic device 100 may determine whether synchronization of the updated positioning profile is required with the rest of the network. For example, in the case where a change of the positioning profile may affect cooperative positioning, it may be determined that synchronization of the positioning profile is required. For example, in the case where the state of the peripheral electronic device 200 that has a unique positioning means within a network is changed from an insufficient battery power state (e.g., a state in in which the remaining battery power of the device 200 fails to meet a threshold) to a positioning-enabled battery state (e.g., a state in in which the remaining battery power of the device 200 meets the threshold), it may be determined that synchronization of the positioning profile is required. However, in some instances, when at least one of the peripheral electronic devices 200 - 1 to 200 - 3 transitions from an insufficient battery power state to a positioning-enabled battery state, it may be determined that the synchronization is not required if the other electronic devices have the same positioning means. For another example, in the case where a specific electronic device enters a sleep mode, the electronic device may update the positioning profile and may perform synchronization immediately before entering the sleep mode.
According to an embodiment of the present disclosure, the main electronic device 100 or the peripheral electronic device 200 may delete at least one of the positioning profiles that are stored in the memory of the main electronic device 100 . For example, if a certain electronic device is determined as not being necessary for cooperative positioning or is excluded by the user, the positioning profile of the electronic device may be deleted. Therefore, unnecessary use of a memory may be prevented.
If a positioning event occurs, the main electronic device 100 may determine positioning roles of the main electronic device 100 and the peripheral electronic device 200 on the basis of the positioning profile. The positioning event may be, for example, user's manipulation, geo-fence entry/exit, change of a remaining battery capacity, change of the positioning profile, or the like. For example, the positioning event may include the case where a remaining battery capacity of the main electronic device 100 decreases to a specified capacity level or lower, the case where the remaining battery capacity of the peripheral electronic device 200 is higher than that of the main electronic device 100 , or the case where a function that requires high battery power consumption is performed in the main electronic device 100 . For another example, the positioning event may include the case where an available positioning means is turned off or information required for positioning is not received normally. For another example, the positioning event may include the case where the main electronic device 100 or the peripheral electronic device 200 enters a sleep mode.
According to an embodiment of the present disclosure, when determining positioning roles, the main electronic device 100 may check whether the positioning profile is valid. For example, if a specified time or a longer time has elapsed since the last update of the positioning profile, it may be determined that the positioning profile is not valid. If it is determined that the positioning profile is not valid, the main electronic device 100 may update the positioning profile of the main electronic device 100 or the peripheral electronic device 200 . Alternatively, if it is determined that the positioning profile is not valid, the main electronic device 100 may request currently available positioning means information from the peripheral electronic device 200 .
According to an embodiment of the present disclosure, when determining positioning roles, the main electronic device 100 may specify an electronic device that is to perform positioning and a positioning means that is to be used by the specified electronic device when performing the positioning. According to another embodiment of the present disclosure, when determining positioning roles, the main electronic device 100 may specify only an electronic device that is to perform positioning and may not specify a positioning means of the electronic device. In the case where a positioning means is not specified, the electronic device designated to perform positioning may perform positioning using at least some of its available positioning means.
For example, when the main electronic device 100 determines that the third peripheral electronic device 200 - 3 should perform GPS positioning, the main electronic device 100 may provide, to the third peripheral electronic device 200 - 3 , A-GPS information, electronic map database information of a specific region, and Wi-Fi AP scanning information. In addition, the second peripheral electronic device 200 - 2 may provide VLC information to the third peripheral electronic device 200 - 3 , and the first peripheral electronic device 200 - 1 may provide PDR information to the third peripheral electronic device 200 - 3 .
According to an embodiment of the present disclosure, the main electronic device 100 may determine positioning roles according to a positioning purpose. According to an embodiment of the present disclosure, the main electronic device 100 may determine positioning roles so that power consumption of the main electronic device 100 or the peripheral electronic device 200 is minimized. According to an embodiment of the present disclosure, the main electronic device 100 may determine positioning roles so that an error in location information obtained through positioning is minimized. According to an embodiment of the present disclosure, the main electronic device 100 may determine positioning roles so that a time required for positioning is minimized.
The main electronic device 100 or the peripheral electronic devices 200 - 1 to 200 - 3 may perform positioning according to determined positioning roles. For example, the main electronic device 100 may provide, to the third peripheral electronic device 200 - 3 , the A-GPS information, the electronic map database information of a specific region, and the Wi-Fi AP scanning information, and the second peripheral electronic device 200 - 2 may provide the VLC information to the third peripheral electronic device 200 - 3 . The first peripheral electronic device 200 - 1 may provide the PDR information to the third peripheral electronic device 200 - 3 . The third peripheral electronic device 200 - 3 may perform positioning using the information received from the main electronic device 100 and the first and second peripheral electronic devices 200 - 1 and 200 - 2 . For example, the third peripheral electronic device 200 - 3 may perform GPS positioning using the A-GPS information. Furthermore, the third peripheral electronic device 200 - 3 may obtain detailed information (e.g., an address, a URL, event information, or the like) of a specific location using the electronic map database information. If the GPS positioning is unable to be performed, the PDR information may be used to mark a current location on a map. In addition, an indoor location may be determined using the Wi-Fi AP scanning information.
According to an embodiment of the present disclosure, the main electronic device 100 may transmit, to the peripheral electronic devices 200 - 1 to 200 - 3 , control signals (e.g., a control signal for requesting location information or supplemental location information) corresponding to the determined positioning roles, and the peripheral electronic devices 200 - 1 to 200 - 3 may perform positioning according to the control signals received from the main electronic device 100 .
Although it has been described that the main electronic device 100 determines positioning roles, the peripheral electronic device 200 that shares the positioning profile with another electronic device may also determine positioning roles according to an embodiment of the present disclosure.

In operation 1140 , upon receiving the location information or the supplemental location information from the peripheral electronic device 200 , the main electronic device 100 may determine a location of the electronic device 100 using the received location information or supplemental location information. For example, the main electronic device 100 may determine the location information received from the peripheral electronic device 200 as the location of the main electronic device 100 . For another example, the main electronic device 100 may determine the location of the main electronic device 100 using the location information received from the peripheral electronic device 200 and location information obtained by the main electronic device 100 using another positioning means. For another example, the main electronic device 100 may perform positioning using the supplemental location information received from the peripheral electronic device 200 , and may determine location information obtained as a result of the positioning as the location of the main electronic device 100 .

Information indicating that a connection to a vehicle is established through the outer network may be obtained, and information indicating that GPS positioning is enabled in the vehicle may be obtained. A terminal that has obtained such outer network information may dynamically change a positioning method of the terminal on the basis of the information. For example, the terminal may perform GPS positioning before being connected to the vehicle, but, if information on the outer network (in this case, a GPS-positioning-enabled vehicle is included in the outer network) is synchronized, the terminal may suspend the GPS positioning or may change a period of the GPS positioning. Alternatively, the positioning method may be changed from the GPS positioning to another positioning method. For example, since the GSP positioning requires high power consumption, the positioning method may be changed to cell-based positioning that requires less power than that of the GPS positioning. As described above, the reliability of a positioning value may be improved using a GPS positioning value received from a vehicle and a positioning value obtained by a user's terminal.
Furthermore, in the case where the terminal comes indoors, the outer network may support ultrasonic positioning. In this case, at the moment when the terminal determines that it comes indoors, the terminal may activate a specified positioning module (in this case, a speaker module for ultrasonic positioning) so as to check a positioning method available in the outer network. Alternatively, at the moment when the terminal determines that it comes indoors, the terminal may receive the positioning profile from the outer network. Alternatively, the terminal may periodically request an external positioning profile to receive the external positioning profile from the outer network. The terminal that has received information indicating that ultrasonic positioning is enabled in the outer network may activate a speaker module and may perform ultrasonic positioning. In this case, the terminal may suspend positioning performed according to a previous positioning method. Alternatively, the terminal may change a period of the positioning performed according to the previous positioning method.
Furthermore, a positioning result of the terminal or information obtained through operation of the terminal may be transmitted to the outer network so that a value corresponding to the result or information may be used in the outer network. For example, the terminal performs positioning using the outer network and a WPS. In this case, the terminal may transmit scanned information of Wi-Fi to the outer network so that a WPS-related database, among the positioning profiles of the outer network, may be updated. At this moment, if Bluetooth currently operates, Bluetooth-scanned information may also be obtained by the terminal. The information obtained in this manner may be transmitted to the outer network through Wi-Fi. The outer network that has received this information may update a Bluetooth-related database using the information.
<Monitoring a Geo-Fence of a Terminal by a Vehicle>
According to an embodiment of the present disclosure, a user in a vehicle may associate a smartphone of the user with the vehicle. The smartphone associated with the vehicle recognizes that a positioning device including a GPS module exists in the vehicle, and transmits geo-fence information set in the smartphone to a navigation system of the vehicle. Since the navigation system is installed in the vehicle, a location of the vehicle may be detected in real time using a satellite navigation system such as the GPS while the vehicle is driven. Therefore, the geo-fence monitoring may be performed by the vehicle's systems while the vehicle is driven. Moreover, while the geo-fence monitoring is performed by the vehicle, the smartphone enters a sleep mode to suspend performance of geo-fence monitoring, or reduces the frequency of monitoring operation to decrease the number of times of wake up, thereby reducing battery power consumption. Geo-fence monitoring is performed until a connection to the vehicle is released, and the occurrence of geo-fence entry is notified to the smartphone.
<Interworking with an Inner Network of Another User>
According to an embodiment of the present disclosure, cooperative positioning may be performed between an inner network including an electronic device of one person and an inner network including an electronic device of another person.
A user A performs cooperative positioning using a smartphone and a smartwatch, and a user B performs cooperative positioning using a smartphone and smart glasses. The user A performs GPS positioning using the smartphone, and performs WPS positioning using the smartwatch. The user B performs WPS positioning using the smartphone, and performs VLC positioning using the smart glasses.
When the users A and B approach each other within a distance that enables communication between a device that is carried by the user A and the user B, the users A and B may form a group together. If the group is formed, the positioning profile of the inner network of the user A is shared with the positioning profile of the inner network of the user B, and an integrated positioning profile is generated, so that the users A and B may form a massive inner network together. The electronic devices of both the users A and B are functionally connected to the massive inner network. Therefore, on the basis of the integrated positioning profile, the smartphone of the user A may perform GPS positioning, the smartphone of the user B may perform Wi-Fi scanning, and the smart glasses of the user B may perform VLC positioning. Since a Wi-Fi scanning operation of the smartwatch of the user A overlaps with that of the smart phone of the user B, the operation of the smartwatch of the user A may be suspended. The process of generating the integrated positioning profile may be determined by a master electronic device, and, if there exists a common communication protocol related to cooperative positioning, a role of each electronic device may be determined on the basis of the common communication protocol.
<Interworking with an Electronic Device of Another User>
According an embodiment of the present disclosure, an electronic device of a person may be associated with a network including electronic devices of another person.
A user A carries a smartphone and wears a smart band, and these electronic devices form an inner network. Here, when a smartphone of a user B approaches the inner network of the user A, the user A may add the smartphone of the user B to the inner network of the user A.
The user B transmits A-GPS information that has been used in positioning by the smartphone of the user B to the smartphone of the user A on the network, and the smartphone of the user A may perform GPS positioning. Location information determined by the smartphone of the user A may be transferred to the smartphone of the user B on the inner network.
In the case where the smart band of the user A receives a BLE signal transmitted from a coffee shop, the smartphone of the user A and the smartphone of the user B may simultaneously receive coffee shop information received by the smart band of the user A.
<Positioning Module Change According to a State of an Electronic Device and Data Transmission for Obtaining Location Information>
According to an embodiment of the present disclosure, a request for location information may be sent to the peripheral electronic device 200 according to a battery level state. While a terminal is associated with a smartwatch, if a battery level of the terminal decreases to a reference value or less, or if a remaining battery capacity of the smartwatch is higher than that of the terminal, the terminal may request the smartwatch to perform positioning. Here, the positioning request may be intended to simply make a request for positioning. Alternatively, a positioning method that is currently available in the smartwatch may be specified on the basis of the positioning profile such as GPS, WPS, PDR, or the like so as to accompany the positioning request, or a positioning method may be specified according to the type of an application used in the terminal so as to accompany the positioning request. For example, in the case where the terminal runs an application that requires accurate location information, an accurate positioning method such as a GPS-based method may be specified to make the positioning request. For another example, in the case where the terminal runs an application that requires low power consumption and relatively less accurate location information such as geo-fence monitoring, a positioning method such as cell-based positioning may be specified to make the positioning request. Furthermore, the terminal may specify a positioning method different from a positioning method currently used in the terminal, so as to transmit the positioning request to the smartwatch.
If the terminal has valid supplemental location information, this information may be transmitted to the smartwatch together with the positioning request. For example, if the terminal has tile information for WPS positioning, the terminal may transmit the tile information to the smartwatch together with the positioning request. The smartwatch that has received the positioning request may request supplemental location information required for positioning from the terminal. If the supplemental location information required for positioning and possessed by the terminal is not valid, the smartwatch may receive valid data for positioning via a wireless network of the smartwatch.
The smartwatch that has completed positioning may continue to perform positioning, or may terminate a positioning operation. A positioning operation of the smartwatch may vary with the type of an application that requires location information. For example, in the case where a navigation application requires positioning, the smartwatch may continuously perform positioning. In the case where an application that requires location information only once or only for a certain period of time requests positioning, the smartwatch may perform positioning only one or only for a certain period of time.
The smartwatch that has completed positioning may use obtained location information in the smartwatch. The smartwatch that has completed positioning may transmit the obtained location information to the terminal. Here, the location information may be transmitted to the terminal only once. Alternatively, the location information may be transmitted to the terminal periodically or aperiodically. Alternatively, the location information may be transmitted to the terminal when the terminal requests the location information. Alternatively, the location information may be transmitted to the terminal at a preset time.
The terminal that has requested the smartwatch to perform positioning may enter a sleep mode. The terminal that has requested the smartwatch to perform positioning may change a positioning method. For example, the terminal that has been performing positioning on the basis of the WPS may send a request for WPS positioning to the smartwatch, and then may perform positioning on the basis of the GPS. The terminal that has received the location information from the smartwatch may suspend positioning and may enter a sleep mode. The terminal that has received the location information from the smartwatch may enter a sleep mode while continuing to perform positioning. The terminal that has received the location information from the smartwatch may change a period of positioning.
Although the smartwatch alone has been mentioned with respect to the above example, a plurality of electronic devices may be applied instead of the smartwatch. The plurality of electronic devices may be electronic devices associated with the terminal or other peripheral electronic devices not associated with the terminal. The electronic device may be a vehicle, a home appliance, or a machine-to-machine (M2M)-enabled electronic device.
<Change of a Positioning Entity According to Change of a Positioning Means>
According to an embodiment of the present disclosure, in the case where a module for positioning is turned off in a terminal, a request for location information may be sent to the peripheral electronic device 200 . For example, in the case where a Wi-Fi module of the terminal is turned off, the terminal may not turn on the Wi-Fi module to perform WPS positioning, but instead the smartwatch that has received the positioning request may perform WPS positioning using a Wi-Fi module.
Furthermore, in the case where a module for positioning is in use, a positioning entity may be changed. For example, in the case where the terminal downloads large-scale data at high speed through Wi-Fi, a positioning request may be transmitted to the smartwatch. In the case where the terminal downloads large-scale data at high speed through Wi-Fi, the terminal may perform positioning using a module other than a Wi-Fi module.
Furthermore, in the case where the terminal uses a large amount of CPU resources, a positioning entity may be changed. For example, if it is determined that the terminal uses a large amount of processing resources to simultaneously perform video/voice calling and game or video playback, a positioning request may be sent to the smartwatch.
Furthermore, if an active module exists in the smartwatch, the terminal may send a positioning request to the smartwatch so that the smartwatch may perform positioning using the module. For example, if it is determined that a Bluetooth module is turned on in the smartwatch on the basis of the positioning profile or by exchanging capacity information, the terminal may send, to the smartwatch, a positioning request in which a positioning method based on a Bluetooth module is specified.
<Change of a Positioning Entity at the Time of Entry to a Specific Region>
According to an embodiment of the present disclosure, a terminal may request location information when entering a specific region or a geo-fence. If the terminal obtains, from an outer network, information indicating that VLC positioning is enabled in a specific region when entering the specific region, the terminal may change a positioning entity into the peripheral electronic device 200 capable of VLC positioning. Since VLC positioning is unable to be performed if the terminal is located in a pocket of a user or in a bag, a positioning request may be transmitted through smart glasses that are able to sense light constantly.
In the case where the terminal enters a store in which a Bluetooth tag for transmitting/receiving beacons complying with a Bluetooth 4.0 standard is installed while performing positioning using WPS and PDR indoors, the terminal may suspend an existing positioning system and may transmit, to the smartwatch, a request for switching to a positioning mode based on a beacon. A smartwatch that has received this request may receive a beacon signal through a Bluetooth module so as to detect entry to or exit from the store. Similarly, if it is determined that the user escapes from the store on the basis of the beacon signal, the smartwatch may transmit, to the terminal, a request for positioning based on WPS and PDR.
Furthermore, in the case where the terminal is required to perform earth's magnetic field positioning using a geomagnetic sensor, a positioning entity may be changed to the smartwatch. If the terminal is located in a bag, the terminal may undergo magnetic interference due to an object such as a credit card or the like contained in the bag, and thus may be unable to perform positioning accurately. In such a case, a positioning request may be transmitted to the smartwatch that is more suitable for performing positioning than the terminal. Alternatively, in the case where the terminal determines that magnetic field positioning is not accurate, the terminal may switch the positioning method to another positioning method so as to perform positioning. Alternatively, the terminal may switch the positioning method to a positioning method other than the magnetic field positioning so as to transmit the positioning request to the smartwatch.
Furthermore, in the case where PDR positioning is more accurate in the smartwatch than in the terminal, the positioning request may be transmitted to the smartwatch. For example, if the terminal is located in a pocket or a bag, the accuracy of PDR positioning may degrade. In this case, the terminal may send a request for PDR positioning to the smartwatch.
Furthermore, in the case where the smartwatch receives tag information of RFID such as NFC, the terminal may transmit the positioning request to the smartwatch. Since an RFID tag may provide an accurate location within a short range, corresponding location information may be obtained through the smartwatch. Alternatively, the RFID tag information obtained through the smartwatch may be transmitted to the terminal, so that the terminal may obtain the location information using the RFID tag information.
<Request for Positioning of a Peripheral Electronic Device According to a User Mode>
According to an embodiment of the present disclosure, a request for location information may be sent to the peripheral electronic device 200 according to a function performance operation of a user. For example, if a module such as a GPS module, a Wi-Fi module, or a Bluetooth module exists in an AP when a terminal enters a sleep state, the terminal may be required to wake up the AP for positioning. In this case, a request for location information may be sent to a smartwatch using sleep mode entrance of the terminal as a triggering point. The smartwatch that has received the location information may perform positioning using GPS, Bluetooth, PDR, or the like. The smartwatch that has obtained the location information may transmit the location information to the terminal.
In the case where PDR positioning is performed while the terminal is operated in a sleep mode, a PDR positioning value may be compensated periodically. However, in order to compensate the PDR positioning value, the terminal wakes up the AP to perform positioning. In this case, the terminal may be unable to remain in a sleep mode, causing high battery power consumption. Therefore, the request for the location information may be sent to the smartwatch in order to compensate the PDR positioning value while the terminal performs PDR positioning. The smartwatch that has received the positioning request may perform a positioning operation using an available positioning method, and may transmit obtained location information to the terminal. The terminal may compensate the PDR compensation value using the location information.
<Positioning Profile Setting According to Context>
According to an embodiment of the present disclosure, the positioning profile may be continuously switched according to a moving speed of a terminal or an inner network.
For example, a user may define a vehicle, cycle, or pedestrian state through a sensor of an electronic device. In the case of a vehicle having a relatively high speed, functions of GPS positioning, cell positioning, and Wi-Fi positioning which are generally used outdoors and enable positioning over a wide area may be set in the positioning profile. In the case of a cycle, GPS positioning, Wi-Fi positioning, and a BLE beacon service may be set in the positioning profile in consideration of an outdoor feature and a feature of moving around buildings. In the case of a pedestrian state, Wi-Fi positioning, fingerprint collection, BLE beacon, and proximity positioning may be set in the positioning profile in consideration of a feature of not differentiating an indoor place and an outdoor place, a relatively low speed, and a degree of freedom of movement.
<Sharing Geo-Fence Information in Emergency>
According to an embodiment of the present disclosure, geo-fence information may be shared when an emergency situation occurs.
For example, when an emergency situation occurs, a first user may set a region where the first user is located as a geo-fence, and may consistently notify a current emergency situation of the first user to the periphery thereof through BLE. When a second user enters the geo-fence set by the first user on the second user's way to its destination, a least one device of the second user may receive a BLE signal of the first user, and the second user may be guided to the first user on the basis of the BLE signal.
The first user may set its electronic devices such that, if a remaining battery capacity of a first electronic device that transmits the BLE signal becomes insufficient, the BLE signal is transmitted by a second electronic device capable of transmitting the BLE signal. An inner network of the first user may be scheduled so that an emergency signal is generated for a long time in consideration of a mutual current consumption state and availability of signal generation.
<Positioning Control According to a Traffic Situation>
According to an embodiment of the present disclosure, positioning may be controlled according to a traffic situation.
While a vehicle is driven, traffic state information may be received via a public network so that it may be determined that the vehicle is currently located in a traffic congestion section, or, it may be determined that the vehicle undergoes traffic congestion on the basis of internal vehicle information obtained through, for example, a vehicle meter. If the vehicle undergoes traffic congestion, a positioning operation of an electronic device connected within the vehicle may be disabled (e.g., GPS off, Wi-Fi scanning stop).
If the vehicle moves again or the traffic congestion is mitigated, an odometer or the like may recognize the movement of the vehicle and may share a vehicle movement state with other devices connected to a vehicle network. The other devices may enable positioning means deactivated.
In the case where the vehicle is in the traffic congestion section, a navigation device may suspend GPS operation or may increase a positioning period thereof. Furthermore, traveled distance information may be received through the odometer of the vehicle, and the location of the vehicle marked on the navigation device may be updated on the basis of the traveled distance information. If the traffic congestion is mitigated, the GPS operation is enabled so that a current location may be determined and marked on the navigation device.
<Altitude Information Acquisition Through Cooperative Positioning>
According to an embodiment of the present disclosure, altitude information may be determined through cooperative positioning.
A smartphone that is a first electronic device may have current location information. The smartphone may share the current location information with a watch-type device that is a second electronic device. The watch-type device may provide the current location information to a weather center or a weather service provider, and may receive barometric pressure information of a reference location of which an altitude is to be calculated, such as a sea level pressure of the current location. A band-type device that is a third electronic device may measure a barometric pressure of the current location using a barometric pressure sensor. The watch-type device may provide received sea level pressure information to the band-type device, and the band-type device may determine the altitude of the current location on the basis of the received sea level pressure information. Equation 1 is used to calculate an altitude using a barometer.

<Selection of an Alternative Positioning Means from Among Peripheral Electronic Devices in a GPS Shadow Area>
According to an embodiment of the present disclosure, a satellite navigation system alone, which is a device for positioning, is installed as a device for monitoring a life pattern of a user. The user unintentionally enters a shadow area in which a visible path between a satellite and a device is not secured, such as an indoor place or an area where buildings are concentrated. At this moment, a positioning control module included in a life pattern monitoring electronic device synchronizes the positioning profile with that of the peripheral electronic device 200 , and selects the peripheral electronic device 200 having a positioning device in addition to a satellite navigation system according to the positioning profile. Here, the positioning control module selects a device attached to a shoe capable of performing a PDR function, and requests and receives location information from the shoe, and then uses the location information. Thereafter, it is determined whether the user is outside the shadow area on the basis of map information of the electronic device and PDR information received from the shoe. If it is determined that the user is outside the shadow area, the electronic device operates the satellite navigation system, and consistently receives the PDR information from the shoe until a positioning result is received from the satellite navigation system, so as to use the PDR information to determine the location of the user.
<Using a Smartwatch or Smart Glasses as an Alternative Positioning Means>
According to an embodiment of the present disclosure, a user that uses a smartphone, a smartwatch, and smart glasses receives a location information request from a social network service (SNS) friend, consents to location sharing through the smart glasses, and starts positioning through the smartphone. However, the user may place the smartphone in a bag, a pocket, a handbag, or the like since the user wears the smartwatch or the smart glasses. Therefore, a signal from a satellite may be so weak that the smartphone may be unable to receive a satellite signal. In such a situation, the smartphone may recognize that it is connected to the smartwatch and the smart glasses through the positioning profile from a positioning manager, and may request location information from all the connected peripheral electronic devices 200 . A module for recognizing a VLC signal installed in the smart glasses may receive an LED signal from a billboard of an adjacent building, and may obtain an ID transmitted from an LED. A positioning device of the smart glasses may detect a location of a region corresponding to the ID by searching a DB stored in an electronic device or a network, and may transfer location information to the smartphone. The smartwatch may recognize an inaudible frequency signal through a microphone of the smartwatch, and may transfer location information based on local advertisement information, address information, or the like to the smartphone. The smartphone that has received the location information from the two electronic devices may select or combine location information to be transmitted to the friend so as to use the selected or combined information as final location information.
<Using Time Information of a Peripheral Electronic Device in a Modem-Less Electronic Device>
According to an embodiment of the present disclosure, when a tablet PC not equipped with a modem performs positioning using the GPS, the table PC is unable to obtain time information from a modem. The time information, which is important for the GPS operated time synchronously, is one of the important parameters for quickly obtaining satellite information and calculating a location. In addition, there may be a reference location that is a parameter for assisting in satellite signal search window size and location determination in order to obtain a GPS signal together with the time information. In general, a location that is a reference for determining a time zone may be used as a reference location of a positioning system using the GPS. However, since the tablet PC not equipped with a modem is unable to obtain the above-mentioned information, the tablet PC may obtain the time information from a network time protocol (NTP) server. In this case, since the tablet PC may access a network through Wi-Fi, power consumption due to operation of a Wi-Fi device may be unavoidable. If there exists the peripheral electronic device 200 equipped with a modem, the above-mentioned information may be obtained therefrom. A positioning manager of the tablet PC may check the positioning profile stored in a positioning database, and may receive network information (MCC, MNC, or the like), time zone information, and time information from a corresponding electronic device. The table PC may receive, from an internal DB or a connected electronic device, information available as initial GPS location coordinates using the time zone information, and may synchronize a GPS positioning device of the tablet PC using the time information obtained from a modem. The GPS positioning device may search for a satellite signal using time synchronization information and an initial reference location received from the peripheral electronic device 200 . The location of the table PC may be more quickly obtained through the GPS, and may be transferred to an application so as to be shown to a user through a display device.
A positioning method of a main electronic device or a peripheral electronic device according to various embodiments of the present disclosure may be implemented as a program executable in the main electronic device or the peripheral electronic device. This program may be stored in various types of recording media.
