FIELD: radio engineering, communication.SUBSTANCE: disclosed are techniques for signalling a packet size limitation of 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 call setup, and signals to a packet-switched terminal that another end of the telephony session is a circuit-switched terminal. In a another 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 minimise data reformatting by the interworking node are described.EFFECT: improved efficiency of moving data packets during a multimedia communication session.15 cl, 5 dwg |
