Abstract

The embodiment of the invention provides a realization method of terminal mobile service in an internet protocol (IP) multimedia subsystem architecture, which comprises the following steps of: in the course of a call of a user, receiving a terminal portability (TP) service trigger request submitted by an integrated services digital network (ISDN) user terminal; according to a TP service request message, establishing a TP service suspending request message; sending the TP service suspending request message to a core network of an IP multimedia subsystem (IMS), so that the core network of the IMS identifies the TP service suspending request, and performs the TP service suspending operation. The embodiment of the invention also provides a realization device of terminal mobile service in the IP multimedia subsystem architecture. The realization scheme of terminal mobile service in the IP multimedia subsystem architecture provided by the embodiment of the invention, the core network of the IMS can identify the TP service initiated by users, the TP service can be distinguished from the Call Hold service, and the handling of billing, traffic statistics and the like for the TP service can be separately performed.

Description

technical field

[0001] The present invention relates to the field of communication technology, in particular to a method and device for realizing terminal mobile services under the framework of an IP multimedia subsystem. Background technique

[0002] TP (Terminal Portability, terminal mobility) service is a unique service for ISDN (integrated service digital network, integrated service digital network) users in the PSTN (Public Switched Telephone Network, public switched telephone network) network. An S interface (S interface refers to the S interface in the ISDN network, that is, the interface for users to access the network, which can be understood as a subscriber line is an S interface) to move a phone from one socket to another socket (socket refers to port connected to the user terminal under the same S-interface), or move a call from one phone to another phone on the same S-interface.

[0003] In the prior art, the TISPAN ts_183036 document defines the implementation...
