Problems solved by technology

[0022] The present invention aims to provide a system, a method and a device for implementing session superposition when a CSI terminal communicates with an IMS terminal, and a method and system for enhancing MGCF, which can solve the problem of the CSI terminal when the CSI terminal communicates with an IMS terminal in the above-mentioned related technologies. The problem of not being able to initiate a multimedia session to the peer IMS terminal. Session superposition means that the calling terminal initiates a session first, and then initiates another session, so that the later initiated session terminates on the same called terminal.

Embodiment Construction

[0074] Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

[0075] The principle of the present invention will be described below with reference to FIG. 2 and FIG. 3 .

[0076] Fig. 2 shows a flowchart of a conversation overlay method according to the principles of the present invention.

[0077] As shown in FIG. 2 , the method for solving session superposition when a CSI terminal communicates with an IMS terminal according to the present invention includes the following steps:

[0078] Step S10, the calling terminal initiates a session request to the called terminal, and the S-CSCF (Serving-CSCF, Serving-CSCF) of the called terminal or the S-CSCF of the calling terminal forwards the session request to the user A CSI-IW interworking functional entity for controlling interworking (that is, an interworking control functional entity), wherein the calling terminal is a CSI terminal or an IMS terminal, and the called termina...

Abstract

The method is used in overlapping the session in the intercommunication between CSI terminal and IMS terminal. It comprise: a) calling terminal initiates a session request to the called terminal, the serving call session control function (S-CSCF) entity of called terminal relays the session request to the intercommunication control function entity of local domain; b) after receiving the session request from the intercommunication control function entity, S-CSCF entity makes associated match for the existed session; c) according to the result of associated match, making session overlapping operation. The invention also reveals a session overlapping device.

Description

technical field [0001] The present invention relates to the communication field, and more specifically, to a system for session superposition when a CSI terminal and an IMS terminal intercommunicate in a packet network, an implementation method and a device thereof, and an MGCF enhanced method and system. Background technique [0002] CSI (Combining CS and IMS services, CS and IMS combined service) is a research topic that people pay attention to in the current 3GPP (3rd Generation Partnership Project, third generation mobile communication standardization partner project) standard. This subject aims to solve how to combine 3G CS (Call Control, call control) domain services with IMS (IP Multimedia Subsystem, IP Multimedia Subsystem) domain services. [0003] The main research content of CSI phase 1 (CSI Phase 1) is how to associate a CS (Circuit Switched, Circuit Switched) domain call of a CS IMS dual-mode terminal with a session in the IMS domain. Due to the limitation of i...
