Problems solved by technology

[0013] ①The amount of user data in IMS is quite large, and the storage of user data in the primary and backup S-CSCF will inevitably occupy a lot of valuable storage space;
[0014] ② In order to ensure the synchronization of user business file data between CSCF devices, repeated transmission of user data wastes considerable bandwidth and seriously affects processing efficiency

Embodiment Construction

[0053] The following will be described in detail in conjunction with the accompanying drawings and embodiments.

[0054] As shown in Figure 2, the more detailed realization of some steps in the present invention is as follows:

[0055] 1. About step (2)

[0056] Step (2) includes:

[0057] (2.1) After receiving the registration information flow, the active S-CSCF (B) will update the user registration status to the HSS (C) through the server assignment request (SAR), and request the user service file;

[0058] (2.2) After receiving the SAR, the HSS (C) queries the database according to the request type and parameters, updates the user's registration status, and then carries the user's business file through the Server Assignment Answer (SAA) message.

[0059] 2. About step (4)

[0060] Step (4) includes:

[0061] (4.1) The active S-CSCF (B) sends the compressed user service profile to the standby S-CSCF (D).

[0062] (4.2) The standby S-CSCF (D) returns a response to the ac...

Abstract

The invention discloses the saving method of a multi-media sub-system user business archive and relates to a data compression strategy in the acquiring course of multi-media sub-system(IMS) network. The invention comprises the following steps: (1): when logging on IMS network, UF(A) transmits the registration information to main S-CSCF; (2): in the registration course of a user equipment, main S-CSCF(B) downloads user business archive data from HSS(C); (3): The main S-CSCF(B) compresses the user business archive data through key word file and saves the user business archive data; (4): the S-CSCF(B) also adopts the compression method in the course that the S-CSCF(B) transmits user business archive backup to S-CSCF(D); (5): the main S-CSCF(B) loops back one response of registration success to UE(A). The invention has the advantages of simple acquiring course, can effectively reduce data storage space of the user business archive and can reduce bandwidth needed by user business archive data synchronization between CSCF equipments.

Description

technical field [0001] The present invention relates to a data compression strategy in the implementation process of the Multimedia Subsystem (IMS) network, in particular, it relates to a call session controller (CSCF) that saves user service files in a compressed manner and backs up the user service files at the CSCF Compression is also used during transmission. Background technique [0002] IMS is the trend of network technology and business development. It is recognized as an important link in the evolution of fixed and mobile networks, and is the best way to realize the convergence (FMC) of fixed and mobile communications. As an important node for call processing, the CSCF is the core device of the IMS network control layer, and realizes the control function of the IMS domain session. According to the different functions of CSCF, it can be divided into three categories: [0003] ●P-CSCF (Proxy CSCF) [0004] ●I-CSCF (inquiry CSCF) [0005] ●S-CSCF (Serving CSCF) [...
