Problems solved by technology

After the network returns to normal, the SIP server may receive registration requests from tens of thousands or even hundreds of thousands of terminals at the same time, and the application layer of the SIP server will process the large number of registration requests. Due to the processing capability of the application layer of the SIP service limited, which leads to SIP server failure. In order to avoid the occurrence of the above situation, in the prior art, a firewall is usually installed on the SIP server side. When the firewall receives a large number of registration requests, the firewall will release the registration requests in batches. At the same time, the firewall may send Terminals that send registration requests too frequently are identified as attack targets, and terminals identified as attack targets are added to the blacklist
[0004] However, after the terminal is added to the blacklist, the terminal cannot perform normal business, and unless the administrator manually intervenes, the terminal that is added to the blacklist cannot resume normal business in a short time, making the user experience poor

Abstract

Embodiments of the present invention provide a SIP registration method, terminal and system. The method includes: the terminal obtains the communication status between the terminal and the SIP server; the terminal judges whether the communication status is normal; when the terminal determines that the communication status is normal, generates a random duration; Register request message. It is used to avoid SIP server failure during the SIP registration process.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of communication, and in particular to a SIP registration method, terminal and system. Background technique [0002] A SIP server and a terminal are included in a Session Initiation Protocol (SIP for short) system. The terminal is, for example, a Voice over Internet Protocol (VoIP for short) terminal. Only after the terminal is registered with the SIP server can normal communication be realized. business. [0003] In actual use, when a network failure occurs in the SIP system (such as SIP server downtime, power outage, etc.), all terminals registered in the SIP server are all offline. Send a registration request to the SIP server until the registration succeeds or stop sending the registration request when it times out. After the network returns to normal, the SIP server may receive registration requests from tens of thousands or even hundreds of thousands of terminals at the same...
