为了使移动通信业务具有各种性能，爱立信公司从其日本标准ＰＤＣ（个人数字蜂窝区系统）的ＣＭＳ３０开始，蜂窝区系统首次采用增强型网络结构。该增强型网络结构展示了将智能网（ＩＮ）结构融入蜂窝区系统的一种方式。作者阐述了ＣＭＳ３０蜂窝区系统在近期将如何发展，以满足新业务的需求。原则上，增强型网络结构适用于所有数字蜂窝区标准，包括欧洲的ＧＳＭ标准、Ｄ－ＡＭＰＳ标准和北美正在出现的ＰＣＳ（个人通信业务）标准。
In order to make the mobile communication business have various performance, Ericsson company adopts the enhanced network structure for the first time since CMS30 of its Japanese standard PDC (personal digital cellular system). This enhanced network structure demonstrates one way to incorporate an intelligent network (IN) fabric into a cellular system. The author explains how the CMS30 cellular system will grow in the near future to meet the needs of new businesses.
