在CDMA2000系统的研发过程中，发现了运行在CDMA2000核心网络上的位置管理技术存在效率问题。该文在CDMA2000系统业务模型的基础上，提出了一种优化技术，这种优化技术无需改变当前核心网络的体系结构，但能大大提高用户位置管理的效率，而且在现存的已初具规模的CDMA2000系统中，很容易通过软件改造实现。关 键 词 位置管理; 位置更新; 位置查询; 临时本地目录号Abstract Location management scheme is very important in mobile communication system. During developing the CDMA2000 system, it is found that location management scheme of CDMA2000 core network works inefficiently. In this paper, an optimized scheme is proposed based on the service model of the current CDMA2000 system. Not changing the system structure of CDMA2000, this optimized scheme can work efficiently. At the same time, this scheme can be easily realized only via software alteration in the current CDMA2000 system.Key words location management; location-updating; location searching; temporary local directory number
