The research actuality of the data throughput of the 2g and 2 . 5g mobile communication systems , and the data service characteristics of cdma2000 ix ev - do system , are analyzed detailed in this paper . on the base of that , the paper puts forward the realization project of increasing the forward / reverse link data throughput of the system : the data schedule arithmetic on forward link , and the data rate control arithmetic on reverse link 本文对2g 、 2 . 5g移动通信系统数据吞吐量问题研究现状、 cdma20001xev - do系统数据业务特点进行了详细分析，在此基础上，提出了提高系统前、反向链路数据吞吐量的实现方法：前向链路的数据调度算法和反向链路的数据速率控制算法。
Locating with cell _ id based on gsm network : in gsm network , this kind of system is called counter - link locating system . the locating process is several base stations detecting the ms ' s signal and sending the information to an information process center , then the information process center calculates the ms ' s location 基于网络的cell _ id定位：这类系统在蜂窝网络中也叫做反向链路定位系统。其定位过程是由多个固定位置接收机同时检测移动台发射的信号，将从各接收信号携带的某种与移动台位置有关的特征信息送到一个信息处理中心进行处理，计算出移动台的估计位置。
