Claim:
1. A method for data packet transport during a multimedia session, the method comprising: determining, by an interworking node, a maximum packet size for a video flow based on a negotiation between a media gateway control function (MGCF) of the interworking node and a circuit-switched terminal, wherein the maximum packet size is determined in part based on a bearer capability exchange between the MGCF and the circuit-switched terminal over a circuit-switched channel having a fixed bandwidth; and sending an SDP message from the interworking node to a packet-switched terminal, the SDP message having information comprising a parameter indicating to the packet-switched terminal the maximum packet size that can be transmitted to the circuit-switched terminal without fragmenting, at a media gateway (MGW) of the interworking node, data packets received from the packet-switched terminal prior to transmission of the data packets by the MGW to the circuit-switched terminal.
