Media binding to coordinate quality of service requirements for media flows in a multimedia session with IP bearer resources

A method for use in setting up a multimedia session between a mobile terminal and a remote host, comprising:

• using session signaling, initiating a multimedia session with plural media data streams between the mobile terminal and a remote host coupled to a packet data network, the mobile terminal being coupled to the packet data network and to a multimedia system that provides multimedia session services by way of General Packet Radio Service (GPRS) network;
• receiving media binding information for each of the plurality of media data streams as a part of the session signaling;
• requesting a GPRS bearer for each media data stream and associating the corresponding media binding information to each GPRS bearer;
• and
• transporting the media data streams using corresponding ones of the GPRS bearers.

A method for use in setting up a multimedia session between a mobile terminal and a remote host, comprising:

• using session signaling, initiating a multimedia session with plural media data streams between the mobile terminal and a remote host coupled to a packet data network, the mobile terminal being coupled to the packet data network and to a multimedia system that provides multimedia session services by way of General Packet Radio Service (GPRS) network;
• receiving session information including a session token at the mobile terminal;
• generating media binding information for each of the plurality of media data streams using the session token and a media flow identifier corresponding to each of the media data streams;
• requesting a GPRS bearer for each media data stream and associating the corresponding media binding information to each GPRS bearer;
• and
• transporting the media data streams using corresponding ones of the GPRS bearers.

For use in setting up a multimedia session between the mobile terminal and a remote host using session signaling, where the multimedia session includes plural media data streams, the mobile terminal being coupled to packet data network and to a multimedia system that provides multimedia session services by way of an access point, the mobile terminal comprising electronic circuitry configured to perform the following tasks:

• initiate the multimedia session using session signaling so that a plurality of media packet access bearers can be established to transport corresponding ones of the media data streams between the mobile terminal and the access point;
• create media binding information for each media data stream;
• and
• use the media binding information to associate each media data stream in the session to one of the media packet access bearers.
