摘　　要：近几年时分同步码分多址接入(TD-SCDMA,Time Division-Synchronization Code DivisionMultiple Access)网络的分组业务(Packet Service)发展迅速,在网络维护和优化过程中发现,随着用户数的大量增加,TD-SCDMA网络的分组业务误块率高的情况日益严重,用户在进行浏览网页或下载等分组业务时,常常会出现速度慢、容易掉线等问题,对用户的使用造成了一定影响。结合实际,对误块率的形成机制和原因进行了分析,并总结了简易可行的分析和优化方法,从实际应用经验来看,是行之有效的。Recently,TD-SCDMA network packet service develops rapidly,and it is found during maintenance and optimization of the network that,with the dramatic increase of users number,the block error ratio of TD-SCDMA network packet service is increasingly serious,and the problems such as low speed and easy drop would occur during users＇ browsing of web pages,down loading and other packet services.This paper,in connection with reality,does some analysis on the formation mechanism and cause of block error ratio,and summarizes some simple and effective analysis and optimization methods.
