【摘要】：现有的移动核心网语音通信中一直采用电路交换的方式进行,在长期的建设和运营中,该方式渐渐暴露出对话务高峰应对能力差、资源利用率低和核心网网络调整繁琐等一系列问题。而随着IP技术的发展,分组交换方式替代电路交换方式已经逐步成为不可逆转的趋势。本文结合目前中国联通GSM/WCDMA网络运营商IP化的进展情况,针对本地网软交换核心层IP化阶段进行了分析,首先探讨了核心网IP化的发展进程和IP化的意义,简单介绍了移动核心网的功能、架构、核心网主要设备、对外接口以及湘潭联通移动核心网的现状,并结合核心网组网设计原则和语音IP化主要技术介绍了湘潭联通IP化改造的方案设计和实施过程,包括IP化对网络的影响、改造目标、改造内容、实施计划、话务网和信令网组网方案,实施方案,改造涉及的协议。湘潭联通从2013年8月开始,根据本方案对本地端局进行改造,到2013年11月完成了全部改造,改造后网络结构得到优化和演进。
[Abstract]:The existing mobile core network voice communication has been using circuit switching, in the long-term construction and operation, the way gradually exposed to the peak response to traffic poor, A series of problems such as low utilization of resources and tedious adjustment of core network. With the development of IP technology, packet-switched alternative circuit switching has become an irreversible trend. According to the development of IP in China Unicom GSM/WCDMA network operator, this paper analyzes the IP stage of local network softswitch core layer. Firstly, it discusses the development process of core network IP and the significance of IP. This paper briefly introduces the function, architecture, main equipment of the core network, external interface and the current situation of Xiangtan Unicom mobile core network. Combined with the core network design principle and the main technology of voice IP, this paper introduces the scheme design and implementation process of Xiangtan Unicom's IP transformation, including the influence of IP on the network, the transformation target, the reform content and the implementation plan. Traffic network and signaling network scheme, implementation scheme, transformation of the protocol involved. Xiangtan Unicom started from August, 2013, according to this plan to transform the local end bureau, by November 2013, completed all the transformation, the network structure has been optimized and evolved after the transformation.
