GSM系统移动交换网络的优化 摘 要 当今科学技术尤其是信息技术的迅猛发展，正引领世界进入信息社会。伴随着世界范围内的信息革命，通信技术正以前年未有的速度发展、更新。特别是移动通信，它作为一个科技密集型和知识密集型的高新技术产业，能够满足人们在任何时间、任何地点与任何个人进行通信的愿望。在我国，移动通信发展势头高涨，每年用户数保持着很高的增长速度。 随着移动用户数量的增加和消费意识的变化，用户对移动网络性能的要求已经越来越高，而且随着我国加入了世贸组织，不同移动网络经营商之间的竞争也越来越激烈。因而网络质量的好坏已经越来越被人们重视，这就要求网络维护工作者们将工作重点从以前单纯的设备维护转移到更高层次的网络优化上来。 本设计是对GSM网络交换系统进行优化。本设计目的在于利用交换网络优化方法达到可以长期、持续、有效地提高交换网络的通信质量。其内容主要包括：GSM移动通信网络的结构及功能应用， GSM中No.7信令基础知识、GSM网络的接口与协议，交换设备CC08数字程控交换机、GSM交换系统中的各种参数等。本设计从信令命名规范，局间信号规范，规范通知音，交换机抗灾难措施，实时监控五方面对交换网络进行系统的优化。最后将GSM-MSC至CDMA-MSC的中继割接至综合关口局使C网G网不直连，通过记录参数计算得到交换系统接通率的提高，达到优化的目的。 关键词：GSM；交换网络；优化；交换系统接通率 Abstract Todays science and technology, especially the rapid development of information technology, is leading the world into the information society.With the worldwide information revolution, the previous years, communications technology is not the speed of development, updating. Especially in mobile communications, as a technology-intensive and knowledge-intensive high-tech industries, to meet at any time, any place and any personal desire to communicate. In China, the rising trend of mobile communications development, the number of users per year to maintain a high growth rate. With the increasing number of mobile subscribers and consumer awareness of the changes, users of mobile networks has become increasingly high performance requirements, and with Chinas accession to the WTO, between different mobile network operators and competition increasingly fierce. The quality of the network which has been growing attention, which requires network maintenance workers who will focus on simple equipment maintenance from the previous shift to a higher-level network optimization up.  The design is to optimize the GSM network switching system. This is designed to exchange network optimization method used to achieve long-term, sustained, effective exchange network to improve communication quality.
