Problems solved by technology

The reason is that, one: sometimes in order to enable the SIP business to start smoothly, it is necessary to control the load of the SIP application server to keep it at a certain level; second, not all the messages forwarded by the SIP agent to the SIP application server are necessary. These messages will cause a waste of transmission resources, and will also increase the load of the SIP application server
However, the prior art has not provided such mechanisms for controlling the flow of messages to SIP application servers

Embodiment Construction

[0055] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0056] The core idea of ​​the present invention is: a SIP message filtering device is set, and the SIP message filtering device generates filtering rules and filters the SIP messages to be sent to the SIP application server by the SIP agent according to the filtering rules, and indicates that the SIP agent discards the SIP messages that meet the filtering rules. SIP messages and send SIP messages that do not meet the filtering rules to the SIP application server.

Abstract

A system for filtering a Session Initial Protocol (SIP) message includes: a SIP Application Server AS, a SIP proxy, a first filtering unit and a second filtering unit; the first filtering unit generates filtering criteria and sends the filtering criteria to the second filtering unit; the second filtering unit filters a SIP message sent from the SIP proxy to the SIP AS according to the filtering criteria, and instructs the SIP proxy to discard the SIP message or instructs the SIP proxy to send the SIP message to the SIP AS. Embodiments of the present invention further provide a method for filtering the SIP message. Because the SIP messages sent from the SIP proxy to the SIP AS are filtered, the load of the SIP AS may be effectively controlled, and unnecessary SIP messages may be intercepted.

Description

technical field [0001] The invention relates to a session initiation protocol (SIP, Session Initiation Protocol) application technology, in particular to a system, device and method for filtering SIP messages. Background technique [0002] The SIP is an Internet Protocol (IP) telephony signaling protocol proposed by the Internet Engineering Task Force (IETF, Internet Engineering Task Force). Its initial purpose is to solve the signaling control in the IP network and communicate with the SIP proxy (SIP proxy), so as to form a next-generation value-added service platform and provide better value-added services for telecommunications, banking, finance and other industries. [0003] SIP is a part of the IETF standard process, and it is established on the basis of protocols such as Simple Mail Transport Protocol (SMTP, Simple Mail Transport Protocol) and Hypertext Transfer Protocol (HTTP, HyperTextTransport Protocol). SIP is described as being used to create, modify, and termina...
