单级号码分析表在移动软交换中的应用

号码分析表是程控交换机根据路由代码映射到具体局向时所需要使用的数据。目前号码分析表主要有两种构成方法:单级表和多级表,一般认为单级号码分析表已经不适应当今交换技术的发展。文章结合移动通信的特点和发展趋势,并结合仿真结果进行分析,对两种路由表在时间和空间上的优缺点进行了对比,验证了在局向配置较少的交换局中使用单级号码分析表的可行性和优点。

The application of single routing cade analysis table in mobile softswitch

Routing code analysis table is used to map the route code to the destination address. Nowadays there are two methods to construct the analysis table: single table and multiple table. This article analysed the features and the trends of mobile communication. We compare the two kinds of tables using the simulation results. After analysis of the results in the time and space domain of the emulation, we validated that the single table can be used in the specifical mobile switch.
