摘要： Systems and methods are disclosed that provide femto-based wireless coverage in a communication network. This can involve providing an interworking function that communications with a femto base station or femto cell to provide connectivity to the core network. The interworking function can provide service and mobility management where a femto cell (such as a home node B (HNB)) is served concurrently by an IMS core and a legacy core. The interworking function can also provide service through a femto cell to a variety of mobile nodes such as legacy devices and IMS capable devices. The interworking function also provides the ability for handoffs to occur between the core networks and between a femto cell and a macro cell.

摘要： Systems and methods are provided that allow the delivery of location based services within a communication network. The location information can be retrieved using information from the mobile node when the mobile node registers in the network. The location information can then be cached or stored in one or more places in the communication network and correlated with the mobile node's addressing information. If a request for location based services is received without location based information, the gateway can use location based information regarding the mobile node to provide location based services. The gateway can enable non IMS mobile nodes to obtain IMS location based services or incompatible mobile nodes to obtain location based services.

摘要： Methods and systems are provided for combining a plurality of data streams into a single data stream for sending to a wireless user. According to the invention, using one or more data mixers, two or more video streams are combined into a single video stream and provided to a wireless user, and/or two or more audio streams are combined into a single audio stream and provided to a wireless user. The streams are optionally decoded and handled in raw format by the data mixer, and at least some of the streams may be buffered in a queue so that “slipping” or synchronization problems can be addressed. The method and system can process media data such as video, audio, text, or other media data.

摘要： The principle object of the present invention, is to provide flexibility in the routing functions performed in the switching system. Another object is to provide a router that can be centralized in a host computer or distributed among various switching nodes. The router is easily programmable by the system operator to provide different routing algorithms for various calls. The router can be used in a system with a single switching node. However, it is particularly adopted for use in a multiple-switching-node system, either as a central, host resident unit, or as a distributed router resident on the switching nodes. A router embodying the invention uses router tables that are readily configurable by the system operator to route calls based on predefined routing criterion in the incoming or outgoing call.

摘要： Systems and methods for transferring a session or components of a session in a communication network are provided. The components of the session include media flows and control over the media flows. The user can initiate a transfer of a existing session with a mobile device such as user equipment (UE) to one or more devices that may lead to fan-out or fan-in to multiple devices. This can include separating the delivery of media from the control of the delivery. For example, a UE can be designated a controller to control another UE, such as a television (TV). In providing the capability to transfer these sessions, a gateway is used to implement network functions that allow the streaming to be controlled and delivered to the respective UEs. In some embodiments, the gateway can be flexible and its operation modified according to messages it receives.

摘要： Systems and methods for providing dynamic changes to a packet flow in a communication network are described. The dynamic changes can include upgrading and downgrading quality of service (QoS), adapting the stream to a receiving device, modifying the stream to counter-act changes in an air interface, and modifying the stream to accommodate an inter-technology handover. These changes can be provided by inspecting packets at a gateway and setting up a proxy for multimedia stream packet flows. The proxy can coordinate transcoding to take place to change the stream. The gateway can also monitor conditions at the mobile node using a real time control protocol or other applicable protocols.
