  • Patent number: 8948160
    Abstract: The present invention relates to providing services for circuit-switched calls from an Internet Protocol (IP) based packet network. In essence, a call originating from or intended for a subscriber that is served by a telephony switch, such as an end office or mobile switching center, in a circuit-switched network is intercepted and routed by the telephony switch to a service node via a subscriber emulator. The subscriber emulator acts as a liaison between the telephony switch of the circuit-switched network and the service node of the packet network. Preferably, the subscriber emulator presents itself to the service node as a user agent, which acts on behalf of a subscriber that is served the telephony switch. The service node provides any requisite processing of the call to implement services for the call.

  • Patent number: 8937959
    Abstract: A distributed switch may include a hierarchy with one or more levels of surrogate sub-switches (and surrogate bridge elements) that enable the distributed switch to scale bandwidth based on the size of the membership of a multicast group. When a sub-switch receives a multicast data frame, it forwards the packet to one of the surrogate sub-switches. Each surrogate sub-switch may then forward the packet to another surrogate in a different hierarchical level or to a destination computing device. Because the surrogates may transmit the data frame in parallel using two or more connection interfaces, the bandwidth used to forward the multicast packet increases for each surrogate used.

  • Patent number: 8913734
    Abstract: A telecommunications addressing system/method allowing selection of a telephone instrument device (TID) using arbitrary identifiers is disclosed. The system/method allows a source TID (STD) to select a target TID (TTD) by the use of a Target Telephone Identifier (TTI) data string rather than a traditional numeric telephone identification (NTI). This TTI is then indexed within a TTI/NTI mapping server (TMS) that functions as a hierarchical repository of TTI/NTI mappings. STD/TTD communication is established by first performing a lookup of the STD-selected TTI within the TMS to identify the NTI of the TTD. Once the NTI of the STD has been identified by the TMS, communication between the STD and TTD is established using the NTI via the normal public switched telephone network (PSTN). TMS TTI lookup may be performed via STD TID web application and/or via PSTN infrastructure interface.

    Abstract: A method of routing calls from a mobile unit to a destination location can include registering the mobile unit with a wireless adjunct, wherein the wireless adjunct is in communication with a switching unit and a packet based network and is operable to receive data from the switching unit and place the data, in packetized form, on the packet based network. The method can further include responding to a call setup request from the mobile unit and querying a subscriber database to determine if the mobile unit is a resident or a guest. If the mobile unit is a resident, communications data can be routed from the mobile unit through the switching unit to a first destination location. If the mobile unit is a guest, communications data can be routed from the mobile unit through an RF source to a second destination location.

  • Patent number: 8861404
    Abstract: IMS networks and methods are disclosed for storing information on the access network of a user in a subscriber profile for the user. When a communication device of a user attempts to register with an IMS network, a P-CSCF receives a register request message from the communication device, and identifies access network information for the user. The P-CSCF then transmits another register request message to an S-CSCF that includes the access network information, and the S-CSCF in turn forwards the access network information to an HSS. The HSS then stores the access network information in the subscriber profile for the user. Nodes in the IMS network that retrieve the subscriber profile may acquire the access network information to provide services based on the access network information.

  • Patent number: 8848880
    Abstract: In one aspect, a communication system allows telephone users to roam between cellular and broadband domains and obtain equivalent level of service and features in the broadband network as in the cellular network. For example, such users can make use of Push-To Talk service, as well as continuous telephone call service, independent of which domain they are connected through. In another aspect, users can pass messages, including voice messages, or establish two-way voice communication between disparate push-to-talk (PTT) or messaging and/or voice systems. For example, a user on a cellular network using a PTT service is able to communicate with a user on a data network using an IM service. In addition, information is passed between the systems to provide coordinated presence information for users. For example, a user can have presence information in multiple networks enabling users form different networks to communication with that user.

  • Patent number: 8848604
    Abstract: Systems and methods are disclosed for correlating messages used to deliver an Application Originated (AO) text message to User Equipment (UE). A text message gateway is implemented between a text message application and a packet-switched network that uses Session Initiation Protocol (SIP). The text message gateway receives a delivery request from the text message application that includes an Application Originated (AO) text message intended for the UE. The text message gateway identifies a correlation identifier (ID) for the AO text message, inserts the correlation ID in a delivery response, and transmits the delivery response to the text message application (to store for later use). The text message gateway also converts the delivery request into a SIP request that encapsulates the AO text message, inserts the correlation ID in the SIP request, and transmits the SIP request to the UE.
