Research On Technical Programmes Of Convergence Of IMS And WCDMA Core Network

IP Multimedia Subsystem(IMS) is looking to the future of open standardization system. From 3GPP R5 first proposed, and was adopted as the FMC TISPAN network architecture is based on SIP protocol to provide IP and multimedia applications, and access to technology has nothing to do (support 2G/3G, Wlan, Wimax, fixed-line broadband access) The system. Based on the IMS architecture can provide IP telephony, video telephony, showing, instant messaging and shared services, etc;With the popularity of IP technology, as individual users to provide IP multimedia, and other diversified business to provide bandwidth and technical assurance. IMS concept of the proposed 3G network and the development of evolution is a close relationship, but only to the ITU IMS network to complete the standard-setting, as to how to carry out the concrete of the IMS and WCDMA core of the integration is not clear that, with the mobile Network integration of the need for the development of more and more prominent, and work in the domestic network is still at an experimental stage, the process of integration in the Senate miscellaneous WCDMA networks makes the evolution of the integration programme has become complex and diverse, this paper will The integration of a variety of programmes of evaluation, in summing up the characteristics of the various options based on a comparison with the optimization of the programme at this stage; research in this paper in the communications and computer equipment general context of the complete, based on the current network computing The ability to greatly enhance the wider use of IP protocol provides a reliable hardware protection, signaling conversion, media control and separation of carrying large consumption of computing power needed to achieve it possible to function, making WACDMA network elements through the transformation to meet the evolving needs.This paper by the ITU definition of the IMS network structure analysis, to understand the definition of IMS network elements function, carry through on WCDMA network core network analysis to the WCDMA 3G network elements of the network function, interface master of understanding the evolution of the network structure The direction of a system of understanding, network integration with the various stages of evolution of the characteristics of the analysis of the first appraisal of the research "to the WCDMA 3G network domain circuit/packet integration of the various evaluation of the programme, according to the evolution of the road network Reasonable integration programmes. " This paper by the IMS session control system uses the SIP protocol and authentication consultations Diameter agreement learning about the two network protocols work mechanism, as well as through the business for several typical scenarios business session control, media consultation processes to improve the analytical section Two research purposes "in the sound level signaling a typical scene of the signaling process design."Through this research paper by following the results of a study, combining the features of mobile networks and the evolution of a more scientific routes viable network topology of the integration programme, 2 with a typical scene of the signaling network business group and business processes interactive network Detailed design. In this paper, the results of research on the process of integration for the IMS network overlay network topology to face the problem of how to resolve the typical business scene and how to conduct business under the exploration of the issue provided a solution, the programme of the technical characteristics of the domestic carriers To the actual process of integration has a reference value.
