Abstract: Using session signaling, a multimedia session with plural media data streams is initiated between the mobile terminal and a remote host coupled to a packet data network. The mobile terminal is coupled to the packet data network and to a multimedia system that provides multimedia session services by way of an access point. A plurality of packet access bearers is established between the mobile terminal and the access point to transport corresponding ones of the media data streams between the mobile terminal and the access points. The media binding information is created for each media data stream. The media binding information associates each media data stream in the session to one of the media packet access bearers and is used to provide session-based control of each of the media packet access bearers. Different example techniques for generating/providing the media information are disclosed.

Abstract: A protocol proxy relationship is established between a non-enabled host and a protocol-enabled router or other node in a multimedia session including a mobile communications network. A mechanism is provided that allows a non-enabled mobile terminal to communicate a protocol proxy request with a protocol-enabled node along an end-to-end path between the mobile terminal and a remote host. A mechanism is further provided to install information in the protocol enabled node so that it can function as the protocol proxy for the non-enabled mobile terminal.

Abstract: A signaling bearer quality of service profile is pre-established and configured in various nodes in an access network. This is a new quality of service class designed to meet the needs of signaling bearers in multimedia sessions. A message requesting a bearer to support a communication between a mobile terminal and an access point to a packet data network is generated. That message includes a signaling quality of service indicator, which when detected, causes a bearer to be established between the mobile terminal and the access point in accordance with the pre-established signaling quality of service profile. The pre-established signaling quality of service profile typically includes low delay and low bit error rates in addition to high priority and accommodation of bursty traffic patterns. A signaling usage indicator may also employed to implement a standard set of minimum signaling bearer capabilities.

Abstract: The present invention provides a method to assure end-to-end quality of service for a multimedia session including plural media data streams. The multimedia session is between a first user terminal associated with a first local access network and a second user terminal associated with a second local access network. The first and second local networks are coupled to an IP backbone network. During session setup, the user terminals each request confirmation from the other that its local access network can provide the quality of service requested for the session. The first user terminal determines whether there are sufficient resources in the first local access network to support a quality of service in its local access network to support a quality of service requested for each of the media data streams. Once this is determined, the first user terminal sends a message to the second user terminal confirming that QoS assurance.

Abstract: The present invention provides a mechanism for coordinating charging for a multimedia session between a mobile terminal and a remote host on both an application/session level and on an IP/access bearer level. The multimedia session is established over a radio access network via a packet-switched access network coupled to a multimedia system. The multimedia system has one or more multimedia servers for providing multimedia services for multimedia sessions. A token associated with the multimedia session is generated and used to correlate session charges for operations performed in the packet-switched access network and for operations performed in the multimedia system.

Abstract: To set up a multimedia session involving a mobile terminal, a session packet access bearer is established between the mobile terminal and an access point to a packet data network by way of a radio access network. The access point is coupled to a multimedia system that provides multimedia session services. Using the session packet access bearer, a multimedia session involving the mobile terminal is initiated that includes a plurality of media data streams. Media packet access bearers between the mobile terminal and the access point are established. Media binding information is used to associate that multimedia session and each media data stream to one of the media packet access bearers used to transport a corresponding one of the media data streams between the mobile terminal and the access point. The media binding information may be used in a variety of ways to set up and control the multimedia session and the media packet access bearers.
