Embodiment Construction

[0025] see figure 1 , which is a schematic flowchart of a method for accessing a multimedia subsystem IMS domain by a CS domain user terminal disclosed in the present invention. This embodiment mainly introduces the method for accessing the IMS domain when the CS domain user terminal serves as the calling device.

[0026] In order to introduce the solution of the present invention more clearly, several functional entities involved in the method are firstly introduced. The user terminal UE is a terminal serving the circuit domain, used as a calling device in this embodiment, and a mobile switching center MSC that provides services for the calling terminal. The calling call state control function CSCF belongs to the functional entities of the IP Multimedia Subsystem IMS domain, and mainly includes a proxy CSCF (P-CSCF), a serving CSCF (S-CSCF) and an inquiry CSCF (I-CSCF). Among them, the P-CSCF is the first contact point of the user terminal in the IP multimedia subsystem; th...

Abstract

The present invention discloses circuit domain terminal accessing multimedia subsystem method. It contains Mobile switching center MSC simulating IMS terminal originating Session Initiation Protocol (SIP) signaling, accessing circuit domain terminal into multimedia subsystem IMS domain. The present invention also discloses searching called circuit domain terminal method through multimedia subsystem, after executing registered called complementary service value added service in multimedia subsystem IMS domain, forward shifting calling to terminal called mobile switching center MSC; said MSC receiving INVITE signaling from IMS domain, resolving called circuit domain terminal number and switching called terminal.

Description

technical field [0001] The present invention relates to the field of network communication, in particular to a method for a circuit domain terminal to access a multimedia subsystem and an implementation device thereof. Background technique [0002] Now the mobile network is based on the system of the circuit domain, and the function of the user terminal is relatively single, and generally only supports voice and simple data services, and IMS (IP Multimedia Subsystem), as the architecture of the next-generation , billing, an open service provision system, and the ability to easily integrate with IT systems are gaining more and more support from telecom equipment manufacturers and telecom operators. Through the IMS system, multimedia value-added services that cannot be provided by the circuit domain can be provided to 3G multimedia user terminals, such as presence services (Presence), instant messaging, and video conferences. [0003] However, the existing circuit domain netw...
