Abstract
A method for service migration is disclosed. A first Serving-Call Session Control Function (S-CSCF) receives a service migration command; the first S-CSCF receives a user's register message sent by an Interrogating-Call Session Control Function (I-CSCF), and decides, according to a preset configuration policy, whether to migrate the user's service. An apparatus and a system for service migration are also disclosed. By using the method, apparatus and system disclosed herein, the user's service can be migrated flexibly.

A service migration method, comprising:
- receiving, by a first Serving-Call Session Control Function (S-CSCF), a service migration command;
- and
- receiving, by the first S-CSCF, a user's register message sent by an Interrogating-Call Session Control Function (I-CSCF), and determining, according to a preset configuration policy, whether to migrate the user's service.
A Serving-Call Session Control Function (S-CSCF), comprising:
- a first receiving unit, configured to receive a service migration command;
- a second receiving unit, configured to receive a user's register message sent by an Interrogating-Call Session Control Function (I-CSCF);
- and
- a deciding unit, configured to, after the second receiving unit receives the user's register message, determine, according to a preset configuration policy, whether to migrate the user's service.
A service migration system, comprising:
- an Interrogating-Call Session Control Function (I-CSCF), configured to send a user's register message to a Serving-Call Session Control Function (S-CSCF);
- and
- the S-CSCF, configured to:
- receive a service migration command;
- and after receiving the register message sent by the I-CSCF, determine, according to a preset configuration policy, whether to migrate the user's service.
