Abstract:
1. In a first communication station operable in a communication system in which multimedia information is communicated between the first communication station and a second communication station, wherein an apparatus, provided in said first communication station, determines an appropriate adaptation to be used for converting packet-formatted data, of which the multimedia information is formed, into a format amenable for transmission upon a link within communication media which forms a connection between the first and second communication stations, said apparatus comprising: a detector which monitors application signaling output by an application or receives notification from an application to determine an appropriate adaptation to be used for converting packet-formatted data from the application to a format amenable for transmission on a link to the second communication station; and a requester, responsive to the determination by said detector, which requests allocation of a special channel defined as a link in said communication media extending between the first and second communication stations, respectively, for communication of the multimedia information and performs said appropriate adaptation to convert said packet-formatted data to a format amenable for transmission on the link, wherein when said detector makes the determination of an appropriate adaptation to be used for converting the packet-formatted data to a format amenable for transmission on the link to the second communication station, said requestor, responsive to said determination, exchanges signaling with means, coupled to said communication media, for setting up the link and processing the converted packet-formatted data in accordance with the signaling, and wherein said appropriate adaptation includes at least one of TCP header compression/decompression, RTP header compression/decompression, and RTP header stripping/regeneration, and wherein the multimedia information comprises a first information-type and at least a second information-type, and wherein a first logical channel is assigned upon which to generate the multimedia information of the first information-type, the first information-type being real-time media and the second information-type being non-real-time media.
