Abstract
A method and application server for providing different services and performing service changes in a multimedia communication system. When a first client invites a second client to join a multimedia session, the server learns which media types are supported by each client, including first and second media types supported by the server. The first client then sends the server a request on a media control channel to transmit media of the first and second types. The server verifies the requested media types are supported by the second client and sends the first client a grant for the requested media types. The server receives a first media burst of the first media type from the first client and retransmits the burst to the second client, and then receives a second media burst of the second media type from the first client and retransmits the burst to the second client.
