摘要
固网软交换向IMS的演进已经成为NGN发展的必然趋势,如何实施演进也成为电信业界关注的焦点。首先介绍了软交换和IMS的体系结构以及AGCF网元的功能,分析了基于固网软交换实现AGCF的可行性,最后提出了具体的设计方案:基于软交换软件架构,沿用系统保障功能、呼叫控制功能和媒体网关控制功能,增加IMS接入功能、IMS终端配置管理功能和IMS终端注册管理功能,并重点阐述了IMS终端注册管理功能的详细设计与实现。
It is the inevitable trend of next generation network(NGN) evolution from fixed network softswitch to IP multimedia subsystem(IMS), it is also a focal point of telecom industry the implementation of evolution. At first the architectures of both softswitch and IMS are introduced, the function of AGCF is presented, the feasibility of AGCF based on fixed network softswitch is analyzed, and finally the specific design scheme is proposed, which is based on software architecture of softswitch, follows the system assurance function,call control function and media gateway control function, adds IMS access function, IMS term configuration management function, IMS term registration management function. This paper describes the detailed design and implementation of IMS term registration management function.
