METHOD FOR NEGOTIATING MESSAGE SESSION RELAY PROTOCOL CONNECTION PARAMETERS

摘要

The present invention discloses a method for negotiating MSRP connection parameters. The method comprises completing the negotiation of the MSRP parameters via a SDP negotiation process between a CPM client at the transmitting side, an originating participation function entity, a terminating participation function entity and a CPM client at the receiving side, that is, carrying the MSRP connection parameters of a transmitter of a SDP datagram in the SDP datagram carried in a session invite message and/or a success response message message. The present invention completes the negotiation of the MSRP parameters by carrying the MSRP connection parameters of the transmitter of the SDP datagram in the SDP datagram carried in the session invite message and/or the success response message, solves the problem in the prior art that the negotiation of the MSRP connection parameters cannot be achieved by a MSRP transmission link, thereby improving a scheme of transmitting a large message mode CPM message.
