Embodiment Construction

[0023] Below in conjunction with accompanying drawing, the implementation of technical scheme is described in further detail:

[0024] In the SIP multiprocessor system applying the present invention, there are at least two or more UAPs (UAProcessor, User Agent Processing Unit) serving as UA (User Agent); at least one SP (Scheduler Processor, scheduling processing unit); at least one LS (Location Service, location service unit). SP, UAP and LS together form a SIP multiprocessor system (or SIP service system) to provide services for external UA. In the SIP service system of the present invention, there are communication links between SP and all UAPs, and there are communication links between UAPs, and they can forward session SIP messages to each other. SP manages and maintains whether all UAPs are available, and puts all available UAPs in a list; SP performs session scheduling according to the available status of UAPs. LS provides location services for all UAPs.

Abstract

The present invention aims to provide a method for implementing session scheduling in a SIP multiprocessor system, which is used for session scheduling in the communication field, including: the scheduling processing unit SP decodes the SIP message, obtains the corresponding session ID, and maps it to each user respectively On the UAP list of the proxy processing unit, the obtained UAPs form a next-hop UAP list; the SP forwards the SIP message to the first UAP in the next-hop UAP list for processing, and notifies the first UAP of the remaining next-hop UAP information; the first UAP After receiving the SIP message, check whether the session is processed; if not, the SP continues to forward the SIP message to the second UAP in the next-hop UAP list for processing, and notifies the second UAP of the remaining next-hop UAP information until the next One-hop UAP list information is empty. The invention occupies few resources, can provide efficient multi-processor SIP session scheduling, and improves the reliability of the SIP service system.

Description

technical field [0001] The invention relates to a session scheduling technology in the communication field, in particular to a session scheduling technology in a multiprocessor system. Background technique [0002] With the development of Internet and broadband technology, voice transmission over IP network (VOIP) technology has been more and more applied in enterprise network and public network. It is used more and more in the communication network. For a carrier-class communication network, it must have large-capacity processing capabilities, and how to achieve large-capacity processing capabilities, distributed multi-processor processing technology is a good way to solve this problem. [0003] In the prior art, the method for implementing session scheduling in a SIP multiprocessor system is to store the corresponding relationship between each session and the processor, and perform scheduling and distribution processing according to the corresponding relationship. This me...
