Third party re-registration method and third party re-registration device

Abstract

The invention relates to a third party re-registration method and a third party re-registration device. According to the method and the device, after local first registration and third party first registration of a terminal are accomplished by a network side, by improving processing mechanism of third party registration and third party re-registration by the network side, times of the third party re-registration by the network side are reduced, signaling interaction times of an ISC interface are further reduced, signaling processing pressure of the ISC interface is reduced, load of related network elements of the ISC interface is reduced, and work efficiency of the network side is improved. The method comprises steps that: after re-registration of the terminal is accomplished by the network side, time duration from present re-registration to the local first registration of the terminal and a re-registration period of the terminal are determined by the network side, whether the third party re-registration is carried out is determined by the network side according to the time duration, the re-registration period of the terminal and a pre-set third party re-registration period of the terminal, and the third party re-registration period is greater than the re-registration period of the terminal.

Description

technical field [0001] The present invention relates to the communication field, in particular to a third-party re-registration method and device. Background technique [0002] Regarding the third-party registration of the terminal on the network side, there are clear instructions in 3GPP TS24.229 and 24.228 and other agreements. The terminal initiates registration to the network side, and the service-call session control function (Server-Call Session Control Function, S-CSCF) on the network side completes the local registration of the terminal, according to the initial filtering rules carried when the terminal initiates registration to the network side Set the third-party registration of the terminal, wherein the initial filtering rule set contains information such as the address of the third-party access stratum (Access Stratum, AS) that the terminal needs to perform third-party registration, and the S-CSCF on the network side will report to the The third-party AS initiat...

AI Technical Summary

Problems solved by technology

[0019] To sum up, with the existing technology, every time the network side completes the local registration of the terminal, regardless of whether the local registration is the first local registration or the local re-registration, the network side will perform a third-party registration, so the use of the existing technology will increase the ISC The number of signaling interactions on the interface will increase the signaling processing pressure of the ISC interface and increase the load on the network elements related to the ISC interface.
