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.
