EFFICIENT INTERWORK BETWEEN MULTIMEDIA SERVICES SWITCHED BY CIRCUIT AND SWITCHED BY PACKAGE DEFINING A MAXIMUM PACKAGE SIZE ATTRIBUTE

摘要

efficient interworking between circuit-switched and packet-switched multimedia services by defining a maximum packet size attribute. techniques for signaling a packet size limitation from a circuit-switched terminal to a packet-switched terminal during a multimedia session such as a multimedia telephony session. in one aspect, an interworking node obtains information from the circuit-switched terminal during the packet call setup that the other end of the telephony session is a circuit-switched terminal. in an additional aspect, the interworking node signals to the packet-switched terminal a maximum packet size limitation negotiated with the circuit-switched terminal. Additional techniques for the packet-switched terminal to accommodate the maximum negotiated packet size to minimize reformatting of data by the interworking node are described.
