Embodiment Construction

[0024] The technical solutions of the present invention will be described in further detail below with reference to the accompanying drawings and embodiments.

[0025] In the IMS environment, the MGCF is a gateway enabling communication between users in the IMS domain and users in the CS domain. All call control signaling from users in the CS domain is directed to the MGCF, which is responsible for the protocol conversion between the integrated services digital network (Integrated Services Digital Network, ISDN) user part or bearer-independent call control and the SIP protocol, and converts the session Forward to IMS. Similarly, all sessions initiated by the IMS domain to users in the CS domain also pass through the MGCF.

[0026] In the present invention, on the one hand, the SIP message sent by the sending device in the IMS domain is forwarded to the Serving-Call Session Control Function (S-CSCF) in the domain, and according to the Telephone Number Mapping Working Group (Te...

Abstract

This invention discloses one method to connect IMS area and CS area, wherein the method to send IMS to CS comprises the following steps: transferring IMS device to service call dialogue control unit; servo call dialogue control unit converts the IMS and CS agreements and number through CS area to receive device. The method for CS to IMS comprises the following steps: CS send device sends message to short message center to IMS media network control unit; the media network gate control unit converts CS and IMS agreement and number to receive device.

Description

technical field [0001] The invention relates to a method for message intercommunication between two networks, in particular to a method for completing the query of user routing information between the two networks through an IMS standard network element media gateway control unit, and realizing the method for IMS domain and CS message intercommunication. Background technique [0002] Multimedia services have long been popular all over the world, but they are based on the good capabilities of fixed Internet networks, without any quality assurance of communication and access. Therefore, the rapid development of mobile Internet protocol (Internet Protocol, referred to as IP) multimedia services is the current telecommunications An imperative for operators. The IP Multimedia Subsystem (IMS for short) is the center for providing end-to-end multimedia services and cluster multimedia services in the core network of the Universal Mobile Telecommunications System (UMTS for short). U...
