Interworking method for message systems and message interworking gateway

Abstract

An interworking method for message systems and a message interworking gateway are provided. When a session initiation protocol (SIP) message system sends a message to a non-SIP message system, the message is first sent to the message interworking gateway through a message session relay protocol (MSRP) channel established between the SIP message system and the message interworking gateway, and then sent to the non-SIP message system by the message interworking gateway. Further, when the non-SIP message system sends a message to the SIP message system, the message is first sent to the message interworking gateway, and then sent to the SIP message system through the MSRP channel by the message interworking gateway. As the MSRP channel established between the SIP message system and the message interworking gateway may transmit large or small messages, the method of interworking message systems and the message interworking gateway provided by embodiments of the present invention may be adopted to achieve the interworking between the SIP message system and the non-SIP message system.
