Embodiment Construction

[0113] Below according to accompanying drawing and embodiment the present invention will be described in further detail:

[0114] In order to realize the object of the present invention, the basic method of the present invention is exactly to connect the core network of the circuit as the access network of the IMS domain with the core network of the multimedia domain, and register the traditional mobile terminal in the IMS domain by the HLR position of the core network of the circuit domain, so that A traditional mobile terminal can initiate / receive SIP session services in the IMS domain. Therefore, the present invention designs two different network models in order to adapt to the current two different network architectures—a bearer and control separation architecture and a non-bearer and control separation architecture.

[0115] Such as figure 2 As shown, under the bearer and control separation architecture, the network model includes the multimedia domain core network and...

Abstract

The system comprises a multi media domain core network and a circuit domain core network. MS accesses the circuit domain core network through RAN; the circuit domain comprises MSCe/VLR in communication with RAN and a mobile user agent (MUA) in communication with MSCe/VLR; the MUA communicates with the CSCF of multi media domain core network to connect the circuit domain core network to said multi media domain as an access network. The method thereof comprises: the circuit domain core network is taken as the access network of IMS to connect to the multi media domain network; the traditional mobile terminal is registered into the IMS domain through the HLR of circuit domain core network so as to make the traditional mobile terminal capable of initiating and receiving the SIP session service, and enjoying the multi media service.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a system and a method for connecting a traditional non-grouping mode mobile terminal to a multimedia domain to provide multimedia services. 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, no matter it is CDMA or GSM / WCDMA, they have experienced such an evolution process from traditional circuit switching network to IP packet switching network with separated control and bearer, and then to all-IP multimedia network. Taking the evolution of CDMA as an example, the bearer of CDMA network has changed from the initial TDM (Time Division Multiplex) bearer to the definition of two evolution stages of LMSD and MMD. IP is selected as the bearer of the core network and access network, and A The interface selects IP as the bearer type. Among them, the ...
