Problems solved by technology

Since there is no relevant signaling network management method defined in SIP, when a device fails or the network is congested, adjacent devices cannot know, and subsequent calls will continue to be sent to the faulty device or the congested network, resulting in call failure or Waste of signaling resources

Embodiment Construction

[0026] Fig. 1 illustrates a schematic flowchart of a method for implementing SIP signaling network management in the present invention, wherein a communication device transmits signaling network management information to one or more adjacent communication devices to implement SIP signaling network management. Only two adjacent communication devices are shown in FIG. 1 , and there may be multiple communication devices in actual situations. As shown in Figure 1, the first communication device can inform the adjacent second communication device of the relevant SIP signaling network management information, and after receiving the information, the second communication device sends a response to the first communication device and according to the information to perform the appropriate action.

[0027] For example: when the first communication device breaks down, it will inform the second communication device of the prohibited transmission information, and after receiving the informa...

Abstract

The method includes following steps: (1) through SIP message, first communication device informs management information of SIP signaling network to second communication device; (2) after receiving SIP message, second communication device executes corresponding processes based on management information of SIP signaling network. The invention increases call completing rate, and prevents waste of signaling resources.

Description

technical field [0001] The invention relates to a signaling network management technology, in particular to a method for realizing SIP signaling network management. Background technique [0002] SIP (Session Initiation Protocol, Session Initiation Protocol) is an application-layer control protocol, which is mainly used to establish, modify, and terminate a multimedia session (or conference) to implement control over a multimedia session (or conference). SIP is composed of SIP basic protocol and a series of SIP extensions. SIP basic protocol is defined by IETF (The Internet Engineering Task Force, Internet Engineering Task Force) RFC 3261, and SIP extension is composed of a series of documents, mainly including RFC 3262, RFC 3311, RFC3323, RFC 3325, RFC 3455, RFC 3903 and more than 20 manuscripts. Among them, the PUBLISH message is extended in RFC3903. [0003] On the basis of RFC 3455, the 3GPP standardization organization further expands SIP according to the characteristi...
