EFFICIENT INTERWORKING BETWEEN CIRCUIT-SWITCHED AND PACKET-SWITCHED MULTIMEDIA SERVICES, REGULATING MAXIMUM PACKET SIZE ATTRIBUTE

摘要

PROBLEM TO BE SOLVED: To avoid inefficient reformatting when sending media from a packet-switched terminal to a circuit-switched terminal.SOLUTION: An interworking node 120 obtains information from a circuit-switched terminal during call setup, and signals to a packet-switched terminal 110 that another end of the telephony session is a circuit-switched terminal 140. In a further aspect, the interworking node signals to the packet-switched terminal a maximum packet size limitation negotiated with the circuit-switched terminal. Further techniques for the packet-switched terminal to accommodate the maximum negotiated packet size to minimize data reformatting by the interworking node are described.
