Embodiment Construction

[0110] In order to make the circuit domain intelligent service control entity unable to perceive the media information of the IMS domain multimedia session, the present invention provides a system for the circuit domain to perceive the media information of the IMS domain multimedia session, as shown in Figure 7, including IM-SSF, and through Si / Sh The HSS connected to the IM-SSF through the interface, the S-CSCF connected to the IM-SSF through the ISC interface, and the SCP (winSCP in the CDMA intelligent network) connected to the IM-SSF through the T1' interface.

[0111] The S-CSCF (Serving Session Control Function Entity) performs session control and registration services for IMS domain users. When the user is in the session, the S-CSCF maintains the session state, and interacts with the IM-SSF through the ISC interface according to the service support needs of the network operator, and the IM-SSF provides corresponding services.

[0112] The HSS stores data related to user...

Abstract

The present invention discloses a method as well as a system for apperceiving IMS field multimedia conversation medium information of circuit field, for solving the problem that the existing circuit field intelligent business control entity can not apperceive IMS field multimedia conversation medium information. The method includes: a business exchanging function entity (IM-SSF) obtains multimedia conversation medium information from the received IMS field conversation control signalling; and IM-SSF report the obtained multimedia conversation medium information to the intelligent business control entity (SCP). The system of the present invention comprises: HSS, SCP and S-CSCF, IM-SSF which connects with the HSS, SCP and S-CSCF separately; interfaces between the IM-SSF and the SCP. The present invention ensures the circuit field intelligent business control entity apperceive IMS field multimedia conversation medium information.

Description

technical field [0001] The present invention relates to the field of communication, in particular to a method and system for the circuit domain to sense the multimedia session media information in the IMS domain. Background technique [0002] The bearer of the next-generation communication network has already begun to switch to IP. From the perspective of communication network development, whether it is CDMA or GSM / WCDMA, they have experienced such an evolution process from the traditional circuit switching network to the IP packet switching network with separated control and bearer, and then to the all-IP multimedia network. Take the evolution of CDMA as an example: CDMA network bearer has changed from the initial TDM bearer to the definition of two evolution stages of LMSD and MMD. IP is selected as the bearer choice for the core network and access network, and the A interface selects IP for the bearer type; In the CDMA LMSD stage, the circuit domain realizes the separati...
