DETAILED DESCRIPTION OF ILLUSTRATIVE EMBODIMENTS
The present disclosure will now be described with respect to the appended drawings. In accordance with FIG. 1 , there is shown a an system 10 in which the disclosure may be implemented in a first embodiment. The system 10 includes a network 12 , which could be any type of communications network, including but not limited to a 3G or 4G wireless network, WiFi or WiMax, CDMA or TDMA, the internet or any other telephony or data network. The network may have fixed interfaces to landline telephones 16 , or interfaces to wireless devices 18 or 20 through base stations 19 and 21 , respectively in accordance with well-known protocols.
The wireless device is representative of any appropriate type of device that can communicate on a wireless network. Example mobile devices include any type of wireless receiver or transceiver device (e.g., cell phone, pager, PDA, PC, specialized broadcast receiving device, satellite radio receiver, satellite phone, and television). Example devices can comprise any appropriate mobile device, such as, for example, a portable device, a variety of computing devices including (a) a portable media player, e.g., a portable music player, such as an MP3 player, a Walkman, etc., (b) a portable computing device, such as a laptop, a personal digital assistant (“PDA”), a portable phone, such as a cell phone or the like, a smart phone, a Session Initiation Protocol (SIP) phone, a video phone, a portable email device, a thin client, a portable gaming device, etc., (c) consumer electronic devices, such as TVs, DVD players, set top boxes, monitors, displays, etc., (d) a public computing device, such as a kiosk, an in-store music sampling device, an automated teller machine (ATM), a cash register, etc., (e) a navigation device whether portable or installed in-vehicle and/or (f) a non-conventional computing device, such as a kitchen appliance, a motor vehicle control (e.g., steering wheel), etc., or a combination thereof. For exemplary purposes only, the mobile device 20 will be referred to as smart phone 20 , though clearly not limited to such.
Continuing with reference to FIG. 1 , the network 12 also includes a visual voice mail server 14 in communication therewith. Internet protocol interface 22 may also be connected to the network 12 and may, for example, be a Wi-Fi hot spot or other connection point to the internet. A personal computer 24 is shown in communication with the interface 22 . A set top box 26 , for example, a uVerse set top box offered by AT&T, may also be in communication with the network 12 and a television display 28 as shown. It is understood that the personal computer may be any type of internet device connected to the network, including but not limited to a desktop computer, a laptop computer, a netbook computer, a tablet, a gaming system or any other type of computing device. The television display 28 may be any type of display which gets its information feed from a set top box 26 .
In accordance with an embodiment, a multi-screen environment may contain three screens such as smartphone 20 , personal computer 24 and television 28 . Each of these screens may be capable of receiving, displaying, and acting upon data associated with visual voice mail.
An example of a visual voice mail screen display 30 is illustrated in FIG. 2 . It will be understood by those skilled in the art that such a display is an example only and different smartphone manufacturers may have different screen layouts and that different carriers may also have different screen layouts. Screen 30 may have listings for a plurality of voice messages, in this example, five messages are displayed. Caller 1 message 32 is highlighted which may indicate that caller 1 message 32 has been selected, while caller 2 message 34 , caller 3 message 36 , caller 4 message 38 , and caller 5 message 40 are not highlighted and therefore not selected by the user. It will be understood that envelope information may be included in the listing of each voice mail such as time of message, the length of message, the location from which the message originated, or any other such information. Action button 33 provides the option for the subscriber to listen to the voice mail from caller 1, while action button 31 provides the option for the subscriber to see a text transcription of the voice mail message from caller 1. Once caller 1 message 32 has been selected, in addition to the action buttons 31 and 33 , the subscriber is also provided other options on control bar 42 , which may, for example, include the options to place a call to caller 1, to reply via text message to caller 1, or to delete the message from caller 1. In accordance with an embodiment, the example screen display 30 in FIG. 2 or variations thereof may be replicated on the smartphone 20 , personal computer 24 and the television 28 .
In accordance with an embodiment and with reference to FIG. 3 , the visual voice mail server 14 may include a state machine 50 , wherein each voice mail message is assigned a status. The state machine 50 may, for example, include four possible states 52 , designated as 1, 2, 3, or 4 with each possible state 52 associated with a particular status 54 . For example, state 1 may be “unread”, state 2 may be “read”, state 3 may be “save”, and state 4 may be “delete.”
In operation and in accordance with FIG. 4 , the visual voice mail server 14 may push a screen display 30 to the smartphone 20 , personal computer 24 and the television 28 at 60 . The screen display may include all stored voice mail messages or a subset of messages which may, for example, be selected based on filtering criteria of the subscriber. At 62 , the subscriber selects a voice mail and performs an action at 64 . When that action is performed, a message is sent back at 66 to the visual voice mail server 14 indicating what type of action was performed. The visual voice mail server then updates the state machine 50 for that message at 68 . At 70 , the synchronization function is performed which results in the visual voice mail server pushing an updated screen display 30 to the smartphone 20 , personal computer 24 and the television 28 after which the process may repeat.
In accordance with another embodiment, the multi-screen environment may also include a multi-user environment. In addition to each voice mail being associated with a specific state, the voice mail may be associated with a particular subscriber, such as a family member. In such a case, an indication of the particular subscriber may also sent to the smartphone 20 , personal computer 24 and the television 28 along with the index of the stored visual voice mail messages. The screen displays 30 may be identical, but the screen displays may also differ for each device. For example, FIG. 5 shows two smartphone screens 72 and 74 and a television screen 76 . In this example, smartphone 72 belongs to “Dad” and smartphone 74 belongs to “Mom”, while the television 76 is shared by both “Dad” and “Mom.” For example, the voice mail messages displayed on the smartphone 72 may be addressed to the particular subscriber (i.e., “Dad”) associated with that smartphone, while the voice messages displayed on smartphone 74 may be addressed to a different subscriber in the same household or office (i.e., “Mom”). All voice mail messages may displayed on the on the television 76 and also may include messages for other members of the family or office.
In accordance with another embodiment, classification data may be included in the envelope information of a voice mail message which would affect the presentation on one or more of the screen displays. For example, the visual voice mail server 14 may classify each visual voice mail as “public” or “private”, with one being selected as a default. The public/private designation may be based upon subject matter, calling party ID, time of day, or any other criteria as selected by the subscriber. For example, “private” messages may include work-related voice mails, attorney-client communications, or the like, while “public” messages may include social or community-related voice mails. With reference to FIG. 6 , there is shown one example of the effects of the private/public designation. In that example, Caller B is designated as private by being displayed in italics on smartphone 78 . That same Caller B does not appear on the television screen 80 , but rather shows up as being designated “Private” in italics. The italics designation is used for illustrative purposes only, but can be any designation, or alternatively, no designation at all. For example, the smartphone screen may not highlight Caller B in any manner whatsoever and the television screen may not even display any indication of Caller B. In accordance with another embodiment, the television screen may also show calls marked private under the control of the subscriber or based on other criteria, such as time of day. If for example, only one subscriber is available and has access to the television during a particular time of day, then all calls, including private calls, may be displayed during that time period. Also, under the control of a subscriber in a similar situation, only calls designated for that subscriber with television access would be displayed on the television screen during that time period. Additionally, the option for the calling party to designate the private/public nature of the voice mail being sent to the subscriber may be provided through a DTMF prompt or other type of prompt from the voice mail server 14 to the calling party.
In order to implement the controls of the three screens, a navigation system may be provided for each screen, indicating the filtering to take place for any screen. The filtering may be the same for all three screens, or customized for each screen. In accordance with an embodiment, a subscriber may select a previously stored profile for a screen by navigating to and selecting the profile for that subscriber. The navigation screen may be hierarchal in nature and may include the ability for a subscriber, with or without password protection, to alter the profile at any time.
Parental controls may also be implemented in an embodiment. Parent may have the ability to review all voice mail messages, regardless of the private/public designation, while at the same time blocking access to all of the parent's voice mail messages by the children. In this manner, children's private messages may be kept private from other children, but not from the parents.
According to another embodiment, the voice mail message may be delivered as a text transcription during the use of the screen by another application. For example, in the context of a television screen, the text transcription of the voice mail message may appear as scrolling text along the bottom or other designated area of the screen while the programming is continually displayed otherwise. According to another embodiment, the text transcription may be displayed on a designated area of the screen as a dialog box-type of display.
The management of visual voice mail may be from the server or from one of the subscriber devices. Filtering and control functions may be provided to permit the subscriber to program the delivery options and review options for each of the multiple screen displays. Priority may be set for each device of for each type of message. Delivery times may be set up such that delivery to one or more of the multiple screens may be based on time of day considerations.
Additionally, the visual voice mail server 14 may be programmed to send reply messages, either automatically or upon command from the subscriber, to the calling party. For example, an acknowledgement of receipt and delivery may be sent automatically by the visual voice mail server 12 to the calling party, or such an acknowledgement may be initiated after prompting the subscriber to authorize the sending of such an acknowledgement. Moreover, the voice mail server 14 may permit the calling party to access the status of previously sent voice mail messages and may, for example, provide the ability for the calling party to recall a message if the message had not yet been accessed or read.
While the embodiments have been described with respect to smartphones 20 and televisions 28 , the same concepts may also be applied to personal computers such that the personal computer may also have personalized or community visual voice mail displays. In accordance with another embodiment, multiple personal computer screens may be used. For example, the visual voice mail may have dual personal computer interfaces, one for a parent and one for a child. The parent computer display may include all of the voice mail messages for both the parent and the child, while the child personal computer display may include only voice mail messages for the child.

The architecture depicted in FIG. 10 is segmented into four groups: users 650 , radio access network 660 , core network 670 , and interconnect network 680 . Users 650 comprise a plurality of end users. Note, device 612 is referred to as a mobile subscriber in the description of network shown in FIG. 10 . In an example embodiment, the device depicted as mobile subscriber 612 comprises a communications device (e.g., wireless anti-theft security M2M type device 36 ). Radio access network 660 comprises a plurality of base station subsystems such as BSSs 662 , which include BTSs 664 and BSCs 666 . Core network 670 comprises a host of various network elements. As illustrated in FIG. 10 , core network 670 may comprise Mobile Switching Center (“MSC”) 671 , Service Control Point (“SCP”) 672 , gateway MSC 673 , SGSN 676 , Home Location Register (“HLR”) 674 , Authentication Center (“AuC”) 675 , Domain Name Server (“DNS”) 677 , and GGSN 678 . Interconnect network 680 also comprises a host of various networks and other network elements. As illustrated in FIG. 10 , interconnect network 680 comprises Public Switched Telephone Network (“PSTN”) 682 , Fixed-End System (“FES”) or Internet 684 , firewall 688 , and Corporate Network 689 .
A mobile switching center can be connected to a large number of base station controllers. At MSC 671 , for instance, depending on the type of traffic, the traffic may be separated in that voice may be sent to Public Switched Telephone Network (“PSTN”) 682 through Gateway MSC (“GMSC”) 673 , and/or data may be sent to SGSN 676 , which then sends the data traffic to GGSN 678 for further forwarding.
When MSC 671 receives call traffic, for example, from BSC 666 , it sends a query to a database hosted by SCP 672 . The SCP 672 processes the request and issues a response to MSC 671 so that it may continue call processing as appropriate.
The HLR 674 is a centralized database for users to register to the GPRS network. HLR 674 stores static information about the subscribers such as the International Mobile Subscriber Identity (“IMSI”), subscribed services, and a key for authenticating the subscriber. HLR 674 also stores dynamic subscriber information such as the current location of the mobile subscriber. Associated with HLR 674 is AuC 675 . AuC 675 is a database that contains the algorithms for authenticating subscribers and includes the associated keys for encryption to safeguard the user input for authentication.
In the following, depending on context, the term “mobile subscriber” sometimes refers to the end user and sometimes to the actual portable device, such as a mobile device, used by an end user of the mobile cellular service. When a mobile subscriber turns on his or her mobile device, the mobile device goes through an attach process by which the mobile device attaches to an SGSN of the GPRS network. In FIG. 10 , when mobile subscriber 612 initiates the attach process by turning on the network capabilities of the mobile device, an attach request is sent by mobile subscriber 612 to SGSN 676 . The SGSN 676 queries another SGSN, to which mobile subscriber 612 was attached before, for the identity of mobile subscriber 612 . Upon receiving the identity of mobile subscriber 612 from the other SGSN, SGSN 676 requests more information from mobile subscriber 612 . This information is used to authenticate mobile subscriber 612 to SGSN 676 by HLR 674 . Once verified, SGSN 676 sends a location update to HLR 674 indicating the change of location to a new SGSN, in this case SGSN 676 . HLR 674 notifies the old SGSN, to which mobile subscriber 612 was attached before, to cancel the location process for mobile subscriber 612 . HLR 674 then notifies SGSN 676 that the location update has been performed. At this time, SGSN 676 sends an Attach Accept message to mobile subscriber 612 , which in turn sends an Attach Complete message to SGSN 676 .
After attaching itself with the network, mobile subscriber 612 then goes through the authentication process. In the authentication process, SGSN 676 sends the authentication information to HLR 674 , which sends information back to SGSN 676 based on the user profile that was part of the user's initial setup. The SGSN 676 then sends a request for authentication and ciphering to mobile subscriber 612 . The mobile subscriber 612 uses an algorithm to send the user identification (ID) and password to SGSN 676 . The SGSN 676 uses the same algorithm and compares the result. If a match occurs, SGSN 676 authenticates mobile subscriber 612 .
Next, the mobile subscriber 612 establishes a user session with the destination network, corporate network 689 , by going through a Packet Data Protocol (“PDP”) activation process. Briefly, in the process, mobile subscriber 612 requests access to the Access Point Name (“APN”), for example, UPS.com, and SGSN 676 receives the activation request from mobile subscriber 612 . SGSN 676 then initiates a Domain Name Service (“DNS”) query to learn which GGSN node has access to the UPS.com APN. The DNS query is sent to the DNS server within the core network 670 , such as DNS 677 , which is provisioned to map to one or more GGSN nodes in the core network 670 . Based on the APN, the mapped GGSN 678 can access the requested corporate network 689 . The SGSN 676 then sends to GGSN 678 a Create Packet Data Protocol (“PDP”) Context Request message that contains necessary information. The GGSN 678 sends a Create PDP Context Response message to SGSN 676 , which then sends an Activate PDP Context Accept message to mobile subscriber 612 .
Once activated, data packets of the call made by mobile subscriber 612 can then go through radio access network 660 , core network 670 , and interconnect network 680 , in a particular fixed-end system or Internet 684 and firewall 688 , to reach corporate network 689 .
FIG. 11 illustrates an exemplary block diagram view of a GSM/GPRS/IP multimedia network architecture within which visual voice mail systems can be implemented. As illustrated, the architecture of FIG. 11 includes a GSM core network 701 , a GPRS network 730 and an IP multimedia network 738 . The GSM core network 701 includes a Mobile Station (MS) 702 , at least one Base Transceiver Station (BTS) 704 and a Base Station Controller (BSC) 706 . The MS 702 is physical equipment or Mobile Equipment (ME), such as a mobile phone or a laptop computer that is used by mobile subscribers, with a Subscriber identity Module (SIM) or a Universal Integrated Circuit Card (UICC). The SIM or UICC includes an International Mobile Subscriber Identity (IMSI), which is a unique identifier of a subscriber. The BTS 704 is physical equipment, such as a radio tower, that enables a radio interface to communicate with the MS. Each BTS may serve more than one MS. The BSC 706 manages radio resources, including the BTS. The BSC may be connected to several BTSs. The BSC and BTS components, in combination, are generally referred to as a base station (BSS) or radio access network (RAN) 703 .
The GSM core network 701 also includes a Mobile Switching Center (MSC) 708 , a Gateway Mobile Switching Center (GMSC) 710 , a Home Location Register (HLR) 712 , Visitor Location Register (VLR) 714 , an Authentication Center (AuC) 718 , and an Equipment Identity Register (EIR) 716 . The MSC 708 performs a switching function for the network. The MSC also performs other functions, such as registration, authentication, location updating, handovers, and call routing. The GMSC 710 provides a gateway between the GSM network and other networks, such as an Integrated Services Digital Network (ISDN) or Public Switched Telephone Networks (PSTNs) 720 . Thus, the GMSC 710 provides interworking functionality with external networks.
The HLR 712 is a database that contains administrative information regarding each subscriber registered in a corresponding GSM network. The HLR 712 also contains the current location of each MS. The VLR 714 is a database that contains selected administrative information from the HLR 712 . The VLR contains information necessary for call control and provision of subscribed services for each MS currently located in a geographical area controlled by the VLR. The HLR 712 and the VLR 714 , together with the MSC 708 , provide the call routing and roaming capabilities of GSM. The AuC 716 provides the parameters needed for authentication and encryption functions. Such parameters allow verification of a subscriber's identity. The EIR 718 stores security-sensitive information about the mobile equipment.
A Short Message Service Center (SMSC) 709 allows one-to-one Short Message Service (SMS) messages to be sent to/from the MS 702 . A Push Proxy Gateway (PPG) 711 is used to “push” (i.e., send without a synchronous request) content to the MS 702 . The PPG 711 acts as a proxy between wired and wireless networks to facilitate pushing of data to the MS 702 . A Short Message Peer to Peer (SMPP) protocol router 713 is provided to convert SMS-based SMPP messages to cell broadcast messages. SMPP is a protocol for exchanging SMS messages between SMS peer entities such as short message service centers. The SMPP protocol is often used to allow third parties, e.g., content suppliers such as news organizations, to submit bulk messages.
To gain access to GSM services, such as speech, data, and short message service (SMS), the MS first registers with the network to indicate its current location by performing a location update and IMSI attach procedure. The MS 702 sends a location update including its current location information to the MSC/VLR, via the BTS 704 and the BSC 706 . The location information is then sent to the MS's HLR. The HLR is updated with the location information received from the MSC/VLR. The location update also is performed when the MS moves to a new location area. Typically, the location update is periodically performed to update the database as location updating events occur.
The GPRS network 730 is logically implemented on the GSM core network architecture by introducing two packet-switching network nodes, a serving GPRS support node (SGSN) 732 , a cell broadcast and a Gateway GPRS support node (GGSN) 734 . The SGSN 732 is at the same hierarchical level as the MSC 708 in the GSM network. The SGSN controls the connection between the GPRS network and the MS 702 . The SGSN also keeps track of individual MS's locations and security functions and access controls.
A Cell Broadcast Center (CBC) 717 communicates cell broadcast messages that are typically delivered to multiple users in a specified area. Cell Broadcast is one-to-many geographically focused service. It enables messages to be communicated to multiple mobile phone customers who are located within a given part of its network coverage area at the time the message is broadcast.
The GGSN 734 provides a gateway between the GPRS network and a public packet network (PDN) or other IP networks 736 . That is, the GGSN provides interworking functionality with external networks, and sets up a logical link to the MS through the SGSN. When packet-switched data leaves the GPRS network, it is transferred to an external TCP-IP network 736 , such as an X.25 network or the Internet. In order to access GPRS services, the MS first attaches itself to the GPRS network by performing an attach procedure. The MS then activates a packet data protocol (PDP) context, thus activating a packet communication session between the MS, the SGSN, and the GGSN.
In a GSM/GPRS network, GPRS services and GSM services can be used in parallel. The MS can operate in one of three classes: class A, class B, and class C. A class A MS can attach to the network for both GPRS services and GSM services simultaneously. A class A MS also supports simultaneous operation of GPRS services and GSM services. For example, class A mobiles can receive GSM voice/data/SMS calls and GPRS data calls at the same time.
A class B MS can attach to the network for both GPRS services and GSM services simultaneously. However, a class B MS does not support simultaneous operation of the GPRS services and GSM services. That is, a class B MS can only use one of the two services at a given time.
A class C MS can attach for only one of the GPRS services and GSM services at a time. Simultaneous attachment and operation of GPRS services and GSM services is not possible with a class C MS.
A GPRS network 730 can be designed to operate in three network operation modes (NOM 1 , NOM 2 and NOM 3 ). A network operation mode of a GPRS network is indicated by a parameter in system information messages transmitted within a cell. The system information messages dictates a MS where to listen for paging messages and how to signal towards the network. The network operation mode represents the capabilities of the GPRS network. In a NOM 1 network, a MS can receive pages from a circuit switched domain (voice call) when engaged in a data call. The MS can suspend the data call or take both simultaneously, depending on the ability of the MS. In a NOM 2 network, a MS may not receive pages from a circuit switched domain when engaged in a data call, since the MS is receiving data and is not listening to a paging channel. In a NOM 3 network, a MS can monitor pages for a circuit switched network while received data and vice versa.
The IP multimedia network 738 was introduced with 3GPP Release 7, and includes an IP multimedia subsystem (IMS) 740 to provide rich multimedia services to end users. A representative set of the network entities within the IMS 740 are a call/session control function (CSCF), a media gateway control function (MGCF) 746 , a media gateway (MGW) 748 , and a master subscriber database, called a home subscriber server (HSS) 750 . The HSS 750 may be common to the GSM network 701 , the GPRS network 730 as well as the IP multimedia network 738 .
The IP multimedia system 740 is built around the call/session control function, of which there are three types: an interrogating CSCF (I-CSCF) 743 , a proxy CSCF (P-CSCF) 742 , and a serving CSCF (S-CSCF) 744 . The P-CSCF 742 is the MS's first point of contact with the IMS 740 . The P-CSCF 742 forwards session initiation protocol (SIP) messages received from the MS to an SIP server in a home network (and vice versa) of the MS. The P-CSCF 742 may also modify an outgoing request according to a set of rules defined by the network operator (for example, address analysis and potential modification).
The I-CSCF 743 , forms an entrance to a home network and hides the inner topology of the home network from other networks and provides flexibility for selecting an S-CSCF. The I-CSCF 743 may contact a subscriber location function (SLF) 745 to determine which HSS 750 to use for the particular subscriber, if multiple HSS's 750 are present. The S-CSCF 744 performs the session control services for the MS 702 . This includes routing originating sessions to external networks and routing terminating sessions to visited networks. The S-CSCF 744 also decides whether an application server (AS) 752 is required to receive information on an incoming SIP session request to ensure appropriate service handling. This decision is based on information received from the HSS 750 (or other sources, such as an application server 752 ). The AS 752 also communicates to a location server 756 (e.g., a Gateway Mobile Location Center (GMLC)) that provides a position (e.g., latitude/longitude coordinates) of the MS 702 .
The HSS 750 contains a subscriber profile and keeps track of which core network node is currently handling the subscriber. It also supports subscriber authentication and authorization functions (AAA). In networks with more than one HSS 750 , a subscriber location function provides information on the HSS 750 that contains the profile of a given subscriber.
The MGCF 746 provides interworking functionality between SIP session control signaling from the IMS 740 and ISUP/BICC call control signaling from the external GSTN networks (not shown). It also controls the media gateway (MGW) 748 that provides user-plane interworking functionality (e.g., converting between AMR- and PCM-coded voice). The MGW 748 also communicates with other IP multimedia networks 754 .
Push to Talk over Cellular (PoC) capable mobile phones register with the wireless network when the phones are in a predefined area (e.g., job site, etc.). When the mobile phones leave the area, they register with the network in their new location as being outside the predefined area. This registration, however, does not indicate the actual physical location of the mobile phones outside the pre-defined area.
FIG. 12 illustrates a PLMN block diagram view of an exemplary architecture in which visual voice mail systems may be incorporated. Mobile Station (MS) 801 is the physical equipment used by the PLMN subscriber. In one illustrative embodiment, communications device 436 may serve as Mobile Station 801 . Mobile Station 801 may be one of, but not limited to, a cellular telephone, a cellular telephone in combination with another electronic device or any other wireless mobile communication device.
Mobile Station 801 may communicate wirelessly with Base Station System (BSS) 810 . BSS 810 contains a Base Station Controller (BSC) 811 and a Base Transceiver Station (BTS) 812 . BSS 810 may include a single BSC 811 /BTS 812 pair (Base Station) or a system of BSC/BTS pairs which are part of a larger network. BSS 810 is responsible for communicating with Mobile Station 801 and may support one or more cells. BSS 810 is responsible for handling cellular traffic and signaling between Mobile Station 801 and Core Network 840 . Typically, BSS 810 performs functions that include, but are not limited to, digital conversion of speech channels, allocation of channels to mobile devices, paging, and transmission/reception of cellular signals.
Additionally, Mobile Station 801 may communicate wirelessly with Radio Network System (RNS) 820 . RNS 820 contains a Radio Network Controller (RNC) 821 and one or more Node(s) B 822 . RNS 820 may support one or more cells. RNS 820 may also include one or more RNC 821 /Node B 822 pairs or alternatively a single RNC 821 may manage multiple Nodes B 822 . RNS 820 is responsible for communicating with Mobile Station 801 in its geographically defined area. RNC 821 is responsible for controlling the Node(s) B 822 that are connected to it and is a control element in a UMTS radio access network. RNC 821 performs functions such as, but not limited to, load control, packet scheduling, handover control, security functions, as well as controlling Mobile Station 801 's access to the Core Network (CN) 840 .
The evolved UMTS Terrestrial Radio Access Network (E-UTRAN) 830 is a radio access network that provides wireless data communications for Mobile Station 801 and User Equipment 802 . E-UTRAN 830 provides higher data rates than traditional UMTS. It is part of the Long Term Evolution (LTE) upgrade for mobile networks and later releases meet the requirements of the International Mobile Telecommunications (IMT) Advanced and are commonly known as a 4G networks. E-UTRAN 830 may include of series of logical network components such as E-UTRAN Node B (eNB) 831 and E-UTRAN Node B (eNB) 832 . E-UTRAN 830 may contain one or more eNBs. User Equipment 802 may be any user device capable of connecting to E-UTRAN 830 including, but not limited to, a personal computer, laptop, mobile device, wireless router, or other device capable of wireless connectivity to E-UTRAN 830 . The improved performance of the E-UTRAN 830 relative to a typical UMTS network allows for increased bandwidth, spectral efficiency, and functionality including, but not limited to, voice, high-speed applications, large data transfer and IPTV, while still allowing for full mobility.
An exemplary embodiment of a mobile data and communication service that may be implemented in the PLMN architecture described in FIG. 12 is the Enhanced Data rates for GSM Evolution (EDGE). EDGE is an enhancement for GPRS networks that implements an improved signal modulation scheme known as 8-PSK (Phase Shift Keying). By increasing network utilization, EDGE may achieve up to three times faster data rates as compared to a typical GPRS network. EDGE may be implemented on any GSM network capable of hosting a GPRS network, making it an ideal upgrade over GPRS since it may provide increased functionality of existing network resources. Evolved EDGE networks are becoming standardized in later releases of the radio telecommunication standards, which provide for even greater efficiency and peak data rates of up to 1 Mbit/s, while still allowing implementation on existing GPRS-capable network infrastructure.
Typically Mobile Station 801 may communicate with any or all of BSS 810 , RNS 820 , or E-UTRAN 830 . In a illustrative system, each of BSS 810 , RNS 820 , and E-UTRAN 830 may provide Mobile Station 801 with access to Core Network 840 . The Core Network 840 may include of a series of devices that route data and communications between end users. Core Network 840 may provide network service functions to users in the Circuit Switched (CS) domain, the Packet Switched (PS) domain or both. The CS domain refers to connections in which dedicated network resources are allocated at the time of connection establishment and then released when the connection is terminated. The PS domain refers to communications and data transfers that make use of autonomous groupings of bits called packets. Each packet may be routed, manipulated, processed or handled independently of all other packets in the PS domain and does not require dedicated network resources.
The Circuit Switched-Media Gateway Function (CS-MGW) 841 is part of Core Network 840 , and interacts with Visitor Location Register (VLR) and Mobile-Services Switching Center (MSC) Server 860 and Gateway MSC Server 861 in order to facilitate Core Network 840 resource control in the CS domain. Functions of CS-MGW 841 include, but are not limited to, media conversion, bearer control, payload processing and other mobile network processing such as handover or anchoring. CS-MGW 840 may receive connections to Mobile Station 801 through BSS 810 , RNS 820 or both.
Serving GPRS Support Node (SGSN) 842 stores subscriber data regarding Mobile Station 801 in order to facilitate network functionality. SGSN 842 may store subscription information such as, but not limited to, the International Mobile Subscriber Identity (IMSI), temporary identities, or Packet Data Protocol (PDP) addresses. SGSN 842 may also store location information such as, but not limited to, the Gateway GPRS Support Node (GGSN) 844 address for each GGSN where an active PDP exists. GGSN 844 may implement a location register function to store subscriber data it receives from SGSN 842 such as subscription or location information.
Serving Gateway (S-GW) 843 is an interface which provides connectivity between E-UTRAN 830 and Core Network 840 . Functions of S-GW 843 include, but are not limited to, packet routing, packet forwarding, transport level packet processing, event reporting to Policy and Charging Rules Function (PCRF) 850 , and mobility anchoring for inter-network mobility. PCRF 850 uses information gathered from S-GW 843 , as well as other sources, to make applicable policy and charging decisions related to data flows, network resources and other network administration functions. Packet Data Network Gateway (PDN-GW) 845 may provide user-to-services connectivity functionality including, but not limited to, network-wide mobility anchoring, bearer session anchoring and control, and IP address allocation for PS domain connections.
Home Subscriber Server (HSS) 863 is a database for user information, and stores subscription data regarding Mobile Station 801 or User Equipment 802 for handling calls or data sessions. Networks may contain one HSS 863 or more if additional resources are required. Exemplary data stored by HSS 863 include, but is not limited to, user identification, numbering and addressing information, security information, or location information. HSS 863 may also provide call or session establishment procedures in both the PS and CS domains.
The VLR/MSC Server 860 provides user location functionality. When Mobile Station 801 enters a new network location, it begins a registration procedure. A MSC Server for that location transfers the location information to the VLR for the area. A VLR and MSC Server may be located in the same computing environment, as is shown by VLR/MSC Server 860 , or alternatively may be located in separate computing environments. A VLR may contain, but is not limited to, user information such as the IMSI, the Temporary Mobile Station Identity (TMSI), the Local Mobile Station Identity (LMSI), the last known location of the mobile station, or the SGSN where the mobile station was previously registered. The MSC server may contain information such as, but not limited to, procedures for Mobile Station 801 registration or procedures for handover of Mobile Station 801 to a different section of the Core Network 840 . GMSC Server 861 may serve as a connection to alternate GMSC Servers for other mobile stations in larger networks.
Equipment Identity Register (EIR) 862 is a logical element which may store the International Mobile Equipment Identities (IMEI) for Mobile Station 801 . In a typical embodiment, user equipment may be classified as either “white listed” or “black listed” depending on its status in the network. In one embodiment, if Mobile Station 801 is stolen and put to use by an unauthorized user, it may be registered as “black listed” in EIR 862 , preventing its use on the network. Mobility Management Entity (MME) 864 is a control node which may track Mobile Station 801 or User Equipment 802 if the devices are idle. Additional functionality may include the ability of MME 864 to contact an idle Mobile Station 801 or User Equipment 802 if retransmission of a previous session is required.
While example embodiments of visual voice mail systems in a multi-screen environment time have been described in connection with various computing devices/processors, the underlying concepts can be applied to any computing device, processor, or system capable of receiving visual voice mail notifications as described herein. The methods and apparatuses for multi-screen visual voice mail applications, or certain aspects or portions thereof, can take the form of program code (i.e., instructions) embodied in tangible storage media having a physical structure, such as floppy diskettes, CD-ROMs, hard drives, or any other machine-readable storage medium having a physical tangible structure (computer-readable storage medium), wherein, when the program code is loaded into and executed by a machine, such as a computer, the machine becomes an apparatus for distributing connectivity and/or transmission time. A computer-readable storage medium, as described herein is an article of manufacture, and thus, not to be construed as a transitory signal. In the case of program code execution on programmable computers, the computing device will generally include a processor, a storage medium readable by the processor (including volatile and non-volatile memory and/or storage elements), at least one input device, and at least one output device. The program(s) can be implemented in assembly or machine language, if desired. The language can be a compiled or interpreted language, and combined with hardware implementations.
The methods and apparatuses for multi-screen visual voice mail systems can be practiced via communications embodied in the form of program code that is transmitted over some transmission medium, such as over electrical wiring or cabling, through fiber optics, wherein, when the program code is received and loaded into and executed by a machine, such as an EPROM, a gate array, a programmable logic device (PLD), a client computer, or the like, the machine becomes an apparatus for processing visual voice mail messages in a multi-screen environment. When implemented on a general-purpose processor, the program code combines with the processor to provide a unique apparatus that operates to invoke the functionality of distributing connectivity and/or transmission time.
While multi-screen visual voice mail systems have been described in connection with the various embodiments of the various figures, it is to be understood that other similar embodiments can be used or modifications and additions can be made to the described embodiments for distributing connectivity and/or transmission time. For example, one skilled in the art will recognize that multi-screen visual voice mail systems as described in the present application may apply to any environment, whether wired or wireless, and may be applied to any number of devices connected via a communications network and interacting across the network. Therefore, systems and methods for multi-screen visual voice mail should not be limited to any single embodiment, but rather should be construed in breadth and scope in accordance with the appended claims.
