呼吸效应对CDMA网络的影响初探

Tentative exploration into the impact of cell breathing effect on CDMA

随着中国电信接手联通CDMA网络之后,用户数的稳步发展,特别是在发达省内部分地区。但在此部分高话务量区域呈现出话务高峰时段Ec/Io等指标突发恶化现象,造成用户感知度变差。本文将通过仿真手段针对呼吸效应现象带来的影响进行定量的分析,并在保证覆盖一定的前提下从网络容量和网络质量的角度阐述两者的关系。

After taking over CDMA from China Unicom,China Telecom has seen the stable development in the number of users,especially within some parts of the developed provinces.But in those areas with heavy speech traffic,the indexs such as Ec/Io all of a sudden deteriorate during the rush hour of the telephone traffic.Such phenomenon will lead to the worsened user’s sensibility.This thesis is devoted to quantitive analysis on the impact of the cell breathing effect phenomenon through method of stimulation,and under the premise of guaranteed cover,from the perspective of both network capacity and network quality it is also devoted to the elaboration of relationship between the two.
