An architecture and procedures by which an NGN can provide the following capabilities to an NGCN user: basic terminating service in the peering model; enhanced terminating services in the peering model; enhanced originating services in the peering model; and roaming service in the subscription and peering models. All capabilities are provided in an easily scalable manner via provisioned subscriber data and small modifications to existing IMS procedures. In the first case, an NGN is configured among the external networks to receive all SIP requests intended for the NGCN users of an NGCN interconnected to the NGN via the peering model (this NGN is the trunking home NGN), and the NGN forwards these requests to the NGCN for handling using request retargeting. In the second case, an NGN is configured among the external networks to receive all SIP requests intended for the NGCN users of an NGCN interconnected to the NGN via the peering model, and the NGN applies a set of agreed services using NGN ASs (application servers) to each request before forwarding to the NGCN for handling. In the third case, the NGCN is configured to forward all originating requests to an NGN (the trunking home NGN) via the peering model, and the NGN applies a set of agreed services using NGN ASs to each request before forwarding to the intended recipient. In the fourth case, an NGN is configured among the external networks as the roaming home NGN to receive a SIP REGISTER request from an NGCN user that has roaming capability, and the NGN forwards that request to the NGCN for handling.

Method for providing IMS support for enterprise PBX users

A method for wireless communications with mobile stations located within a femtocell is described. The method includes registering a femtocell with an IMS core network to receive IMS services for one or more mobile stations located within the femtocell, and separately registering the mobile station with an application server to provide additional services to the mobile station located within the femtocell. The additional services may be CDMA services. Also, registering the femtocell with the IMS core network may include transmitting femtocell registration information that does not include information regarding the mobile station to the IMS core network to request IMS services for the mobile station.

The apparatus and method are fast network SIP/SDP (Session Initiation Protocol/Session Description Protocol) procedures for conference operations upon request from end user with optimization of network resources. The apparatus has an SIP/SDP based network controller that, upon a received request, joins first and second calls into a conference call with at least a third call. The SIP/SDP based network controller is structured to negotiate, allocate and re-configure network resources.

An apparatus in one example comprises one or more network controllers that serve to allow a second user agent to communicate with a first user agent through employment of a codec format unsupported by the first user agent.

Communication between user agents through employment of codec format unsupported by one of the user agents

Apparatus in one example comprises network controller(s) that serve to communicatively couple first network component with second network component. The first network component sends signaling message for the second network component to one or more of the network controller(s). The signaling message comprises indication of specific network connection(s) usable by the first network component. One or more of the network controller(s) serve to replace the indication of the specific network connection(s) usable by the first network component in the signaling message with wild card network connection information. The one or more of the network controller(s) serve to send the signaling message that comprises the wild card network connection information to the second network component. The wild card network connection information indicates the second network component is allowed to indicate to one or more of the network controller(s) specific network connection(s) usable by the second network component.

A communication device is described that includes a POTS interface system, a processing system, a conversion system, a voice interface system, and a digital interface system. When in operation, the POTS interface system receives analog voice signals for a call. The POTS interface system converts the analog voice signals from analog to digital to generate digital voice signals. The processing system performs an application on the digital voice signals to provide a presentation format of the digital voice signals of the call to a user. The conversion system then converts the digital voice signals into analog voice signals and a voice interface system transmits audible signals to the user. The digital interface system receives digital data signals from a data service provider and the processing system performs an application on the digital data signals to provide additional data to the user.

Communication device that provides enhanced services

An apparatus in one example comprises a serving mobile switching center feature server and one or more internet protocol multimedia subsystem components. The serving mobile switching center feature server translates between a call control message originated by or terminated to a mobile telephone and an internet protocol based procedure message. The one or more internet protocol multimedia subsystem components serve to propagate the internet protocol based procedure message. The one or more internet protocol multimedia subsystem components provide packet-switched switching functions to the serving mobile switching center feature server based on the internet protocol based procedure message.

A system for providing statistical multiplexing of speech, other real-time data services and non-real-time data services for point to point and point to multipoint communications. The system has fast access and assignment procedures that allow the multiplexing of real-time, delay-critical data services with non-real-time data services. Continuity of periodic control channels across speech talkspurt and silence periods for conversational voice is maintained to carry signal measurement reports, channel quality feedback, and 'comfort' noise information between different parts of the system.
