Embodiment Construction

[0027] like figure 1 As shown in FIG. 2 , it is a schematic diagram of networking using the S-CSCF resource pool mode. Two or more S-CSCFs can form an S-CSCF resource pool (S-CSCF Pool). Here, three S-CSCFs in the S-CSCF resource pool are taken as an example for illustration. like figure 1 The shown IMS system includes a proxy call session control function entity (P-CSCF, Proxy-Call Session Control Function), an inquiry call session control function entity I-CSCF, a home domain subscriber server (HSS, Home Subscriber Server), S- CSCF resource pool (S-CSCF Pool). The S-CSCF resource pool includes S-CSCF1, S-CSCF2, and S-CSCF3, and the resources of these three S-CSCFs are shared. When one of the S-CSCFs fails, other S-CSCFs in the pool can take over the services of the failed S-CSCF, thereby improving network reliability. S-CSCF is used for registration, session control and processing; P-CSCF is the first entry point for UE to access IMS; I-CSCF is the entry point from the...

Abstract

The embodiment of the invention provides a business migration method which comprises the following procedures: a Serving Call Session Control Function Entity receives an order of carrying out business migration; the first session control function entity receives the register information of users sent by Interrogating Call Session Control Function Entity, and whether to transfer the business of the user is decided according to the preset placement strategies. The embodiment of the invention also provides a device and system for business transfer. The business of users can be transferred through the method, the device and the system provided by the embodiment of the invention.

Description

technical field [0001] The present invention relates to the field of communications, in particular to a method, device and system for service migration. Background technique [0002] In an IP Multimedia Subsystem (IMS, IP Multimedia Subsystem), in order to improve the security of a Serving-Call Session Control Function (S-CSCF, Serving-Call Session Control Function), a resource pool method is adopted. There are multiple S-CSCFs in the resource pool, and the resources of the multiple S-CSCFs in the pool are shared. When one of the S-CSCFs fails, other S-CSCFs in the pool can take over the services of the failed S-CSCF, thereby improving network reliability. Moreover, it can facilitate operation and maintenance. For example, when S-CSCF1 needs to be upgraded, the services of users in S-CSCF1 can be migrated to other S-CSCFs in the pool first, and S-CSCF1 can be upgraded without services. And fully verified, after the upgrade is completed, the user's business is migrated bac...
