Embodiment 1

[0061] figure 1 It is a flow chart of the protocol conversion method provided by Embodiment 1 of the present invention.

[0062] refer to figure 1 , applied to the protocol conversion gateway, the protocol conversion gateway is respectively connected to the SIP system and the third-party system, and there is a one-to-one mapping relationship between the equipment information of the SIP system and the equipment information of the third-party system; the method includes the following steps:

[0063] Step S101, receiving device registration information sent by a third-party system;

[0064] Step S102, according to the device registration information and the mapping relationship, make the third-party system perform device registration or device deregistration with the SIP system;

[0065] Step S103, receiving a session instruction sent by the SIP system;

[0066] Step S104, according to the session instruction and the mapping relationship, make the SIP system establish or cance...

Abstract

The invention provides a protocol conversion method and device which are applied to a protocol conversion gateway, the protocol conversion gateway is connected with an SIP system and a third-party system, and equipment information of the SIP system and equipment information of the third-party system have a one-to-one mapping relation. Comprising the following steps: receiving equipment registration information sent by a third-party system; according to the device registration information and the mapping relation, the third-party system carries out device registration or device logout on the SIP system; receiving a session instruction sent by the SIP system; according to the session instruction and the mapping relation, session establishment or session cancellation is carried out between the SIP system and the third-party system; when the format of the media stream of the SIP system is different from that of the media stream of the third-party system, the media stream of the SIP system or the media stream of the third-party system is subjected to encapsulation conversion processing and transcoding processing, and the processed media stream is obtained; therefore, multimedia communication among different systems is realized.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a protocol conversion method and device. Background technique [0002] SIP (Session Initialization Protocol, Session Initiation Protocol), as an application layer protocol, works in cooperation with other application layer protocols to control multimedia communication sessions through the Internet. SIP signaling is simple in design and strong in scalability, and it is more and more widely used in practical applications. In addition to SIP, third-party protocols such as H323, RTSP (Real Time Streaming Protocol, real-time streaming protocol) and proprietary protocols may be used in some other systems for multimedia communication. Because there are protocol differences between the SIP system and the third-party protocol system, multimedia communication cannot be directly performed. [0003] The SIP and H323 protocols complete the protocol conversion through the protocol conversi...
