基于CDL的精确定位和网络优化探讨

Accurately Positioning and Network Optimization Discussion Based on CDL

CDMA网络中,每一次通话都产生一个CDL(call detail log,通话记录),其记录本次通话的详细过程,包括主、被叫号码,起止时间,占用时隙,CFC代码等,对网络的分析与优化有不可替代的作用。本文通过对CDL数据的分析和解读,阐述了在三角定位算法中引入工程参数和无线环境补偿因子解决CDL数据利用的瓶颈—定位准确性问题,并通过具体的案例,分析了如何利用CDL数据进行网络优化和分析。

CDL including the information about the whole wireless network environment,such as call numbers,calling time,seized CE,CFC.CDL is the most important data for wireless network optimization.The accuracy about positioning is the key problem for how to use the CDL.This essay will represent it by analyzing CDL,bring in the compensation coefficient and parameter of BTS for AFLT to improve the precision of calculation.And it analyses the use case in details to descript how to use these CDL in daily work for wireless network optimization.
