Implementation method for preventing avalanche effect of IMS (IP Multimedia Subsystem) registration

Abstract

The invention provides an implementation method for preventing an avalanche effect of IMS (IP Multimedia Subsystem) registration. The implementation method comprises the following steps of: adding IMS account numbers into a circular registration queue; then registering a first IMS account number at the head of the registration queue in sequence and setting maximum waiting duration; if a response of a registration server is received in the maximum waiting duration, removing the IMS account number from the head of the circular registration queue, and immediately registering the next IMS account number in the circular registration queue; and if no response is received in the maximum waiting duration, stopping registering the IMS account number, and inserting the IMS account number into the tail of the circular registration queue and waiting the next registration choice; and doing the steps repeatedly till the circular registration queue is empty. Therefore, according to the implementation method disclosed by the invention, the avalanche effect of the IMS registration is prevented, all IMS account numbers can be registered as fast as possible, and the total registration time is shortened.

Description

technical field [0001] The invention relates to a realization method for preventing IMS registration avalanche effect, and belongs to the technical field of IMS registration. Background technique [0002] With the development and application of IMS networks, more and more enterprises and operators need to deploy access devices such as IP PBX, and configure a large number of IMS accounts on these devices, and then unify them to SBC (negotiating border controller) Send the REGISTER registration request message, and then the SBC forwards the REGISTER registration request message to the registration server. A large number of REGISTER registration request packets need to be sent to the SBC in a short period of time, which will cause a large load on the network and the registration server, and easily generate an avalanche effect, thereby affecting the performance of the network and the registration server. [0003] In order to deal with the avalanche effect mentioned above, opera...

AI Technical Summary

Problems solved by technology

[0008] According to the above description, when access devices such as IP PBX register a large number of IMS accounts, if some accounts do not receive a response within the interval stipulated in the protocol due to the firewall settings of the SBC or network congestion, the registration message needs to be resent. , which will cause a more intense avalanche effect, and at the same time cause some IMS account registration to take longer or fail to register due to timeout
