  • Patent number: 8494548
    Abstract: In one embodiment, a method includes receiving a request message from a requesting endpoint, where the request message requests a communication session corresponding to an area. An area-based group comprising one or more endpoints associated with the area is identified. The area-based group allows the endpoints to communicate with each other in the communication session. The requesting endpoint is added to the area-based group to allow the requesting endpoint to communicate with the one or more endpoints in the communication session.

  • Patent number: 8346238
    Abstract: A method for communicating in a wireless communication network includes establishing a first direct communication link with a base transceiver station and communicating data associated with a communication session over the first direct communication link. The method also includes establishing a mesh connection to the base transceiver station. The mesh connection includes at least one mesh communication link with at least one intermediate communication device of a plurality of communication devices in the wireless network, the at least one intermediate communication device communicating with the base transceiver station over a second direct communication link with the base transceiver station. The method further includes switching between communicating data associated with the communication session over the first direct communication link and communicating data associated with the communication session over the mesh connection.

  • Patent number: 8116769
    Abstract: Anchoring a communication session for a target mobile phone includes identifying a current access node operable to provide the target mobile phone access to a first network of a first network type. Potential access nodes operable to provide a mobile phone access to a second network of a second network type are identified. Whether the communication session can be handed off to a potential access node of the one or more potential access nodes is established. Anchoring of the communication session is initiated in the second network only if the communication session can be handed off to a potential access node of the one or more potential access nodes.

  • Patent number: 8116776
    Abstract: A method for providing telecommunication service includes transmitting a node identifier to a mobile station over a first network that supports a first communication protocol and receiving a handoff call, based on the node identifier, from the mobile station over a second network that supports a second communication protocol. The handoff call includes a mobile station identifier. The method further includes identifying a first communication link over the first network based on the mobile station identifier and initiating a second communication link with the mobile station over the second network. The method also includes terminating the first communication link.

  • Patent number: 8000710
    Abstract: A method for facilitating communications between wireless networks is provided that includes communicating with a mobile station and transferring a communication session from a first wireless link to a second wireless link. The mobile station is operable to negotiate a first wireless link with a first wireless network, to establish a communication session with a device using the first wireless link, and to facilitate a session handoff with a second wireless link with the second wireless network using the second wireless interface. The handoff is enabled by associating the first wireless link to the second wireless link.

  • Patent number: 7650143
    Abstract: An apparatus for providing connectivity is provided that includes a mobility server operable to coordinate a communication session between a first and a second end-user device. The first end-user device is associated with a first call leg and the second end-user device is associated with a second call leg. A handoff is executed in transferring the communication session from the first end-user device to the second end-user device. In more particular embodiments, the mobility server is operable to receive signal strength information from the first end-user device and to execute the handoff based on the signal strength information. In addition, the handoff is executed based on an end-user preference that is provided in a subscription that is accessed by the mobility server.
