Problems solved by technology

[0007] In practical applications, the above solution has the following problems: when the S-CSCF fails, the services of the relevant users cannot be restored in time, so the continuity of services cannot be maintained, which affects the user experience
[0008] The main reason for this situation is that, in the prior art, once an S-CSCF fails, users served by the failed S-CSCF will not be able to continue to obtain services until these users who cannot continue to obtain services register again , to resume normal session handling for these users
However, since a short registration interval will generate a large amount of communication traffic, the interval between user registrations is generally longer, about tens of minutes
That is to say, if the user registration interval is tens of minutes, then the user who cannot continue to obtain services due to the faulty S-CSCF will still be unable to resume normal session processing within the user registration interval of tens of minutes , affecting the user experience
Moreover, even after the faulty S-CSCF recovers, if these users do not re-register, service may not be restored immediately

Embodiment Construction

[0041] 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.

[0042] The core of the present invention is that when the user successfully registers in the S-CSCF, the S-CSCF initiates the process of saving the user-related information to another S-CSCF that shares the load with the S-CSCF through a third-party registration method. request, and back up the dynamic data required to process the user's SIP request as transparent data to the data backup entity used for backing up data in the HSS or other network devices. When the S-CSCF fails, the network side forwards the SIP request of the registered user in the failed S-CSCF to another S-CSCF sharing the load with the S-CSCF. If the S-CSCF receives a SIP request that does not belong to the registered user of the S-CSCF, it will check whether the SIP request belongs to a third-...

Abstract

The invention discloses an S-CSCF alternate method and system, which is characterized by the following: building AS in the S-CSCF; sending user information to other S-CSCF working with S-CSCF at load share pattern at successful registering time; reserving other S-CSCF in the user information to realize the third registering for user; duplicating the needed dynamic data of S-CSCF in the HSS; transferring the business request of accident S-CSCF at network side to other S-CSCF at S-CSCF accident time; downloading the dynamic data and practice information from HSS according to the third registering information if S-CSCF receives the business request of the third part registered user; providing service for user continually.

Description

technical field [0001] The invention relates to the SIP multimedia subsystem, in particular to the internal backup technology of the SIP multimedia subsystem. Background technique [0002] The mobile communication system can meet people's requirements for communication anytime and anywhere, and has developed rapidly since its appearance. With the introduction and further development of the third generation mobile communication (The Third Generation, referred to as "3G") technology, the bandwidth of the mobile network has greatly increased, and mobile communication will not only be limited to traditional voice communication, but also combine Multimedia services of multiple media types such as text will be developed gradually. The combination of mobile communication with data services such as presence, short message, web browsing, positioning information, push service (PUSH), and file sharing can provide users with more service options. For example, instant messages, chat ro...
