Abstract: 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.

Abstract: 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.

Abstract: The present invention identifies methods and procedures for correlating control plane and user plane data, consolidating and abstracting the learned and correlated data in a form convenient for minimizing and exporting to other network devices, such as those in the Core Network and the Access Network, or the origin server, CDN devices or client device. These correlation methods may use Control Plane information from a plurality of interfaces in the RAN, and User plane information from other interfaces in the RAN or CN. IF the device is deployed as an inline proxy, this information may be exported using in-band communication, such as HTTP extension headers in HTTP Request or Response packets, or another protocol header, such as the IP or GTP-U header field. Alternatively, this information can be exported out-of-band using a separate protocol between the RAN Transit Network Device (RTND) and the receiving device.

Abstract: 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.

The SCIM can be a layer and manage interactions between network devices such as mobile nodes and application servers and can provide abstraction of network devices. This can allow the gateway to provide interworking between network devices and handle mobile nodes with different capabilities.

Abstract: Systems and methods are provided that allow inter-working between communication networks for the delivery of service to mobile nodes. A gateway is provided that communicates with a femto cell to extend service to an area that otherwise does not receive coverage from a service provider.

The femto cell provides service for a mobile node and a gateway permits communication over a broadband network. The gateway integrates the mobile nodes connecting via a femto cell into the service provider's network. The gateway also allows provisioning of services and applications, control of service levels, and provides seamless handoffs to marco base stations and other types of access technologies such as Wi-Fi.

Abstract: 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.

Abstract: Methods and apparatus are provided for reducing call setup delays resulting from non-call related signaling. In session initiation protocol (SIP) messaging, SIP session setup messaging can have the same priority for placement on the airlink to a mobile phone as other non-call session setup messaging. Method and apparatus for providing priority to call session setup messaging are providing, and in some cases, emergency call setup messaging. By providing priority to call setup messaging, delays that might result from being stuck in a queue behind non-call setup messaging can be reduced.
