Method and system for supporting multiple services using SIP protocol

Abstract

The present invention relates to a method for carrying multi-services with use of a SIP protocol, which includes steps as following: step one, a gateway sending a SIP message which expands a head characters, a SIP protocol adapter distinguishing different petitions from different upper service module in a net element by an inner interface between the upper service module with basis of the head characters, filling the head characters of the SIP message with different values and sending them to the opposite net element; step two, another net element receiving the SIP message, a SIP protocol adapter of this net element executing corresponding treatment according to the values of the head characters, and returning the response information to the corresponding upper service module. The invention also provides a system for carrying multi-services with use of a SIP protocol. The invention automatically distinguishes different upper service modules with dependence of software, realizes the carrying of multi-services with needs of only a set of input port and output port, and effectively avoids the disadvantages of that the existed technology excessively occupies network resources and excessively relies on system management.

Description

technical field [0001] The present invention relates to the application technology of the session initiation protocol (Session Initial Protocol, referred to as SIP), in particular to a method and system for carrying multiple services using the SIP protocol. Background technique [0002] Currently, Voice over Internet Protocol (VoIP for short) technology has been widely used in the communication field. It uses the Internet for voice transmission. Compared with the traditional Public Switched Telephone Network (PSTN), it has a great price advantage in terms of networking costs, and fully exploits the role of the data communication network (Internet) , especially suitable for telecom operators to open up new operating areas. [0003] Session Initiation Protocol (SIP) has developed rapidly in recent years. In particular, the transition scheme of the next generation (3G) network, that is, the unified communication scheme, and the next generation (3G) network communication schem...

Problems solved by technology

[0005] However, the disadvantage of this implementation is obvious

First of all, the existing solution needs to occupy a set of ingress port and egress port to provide a SIP service. In today’s increasingly tense network resources, this solution occupies too many network resources, especially the more services provided, the more difficult this solution is implementation; secondly, it relies on the system maintenance personnel of each link to configure correctly according to the requirements, which has great uncertainty and is easily affected by the wrong configuration of a certain link, causing the system to fail to operate normally
