4G地铁扩容评估分析方法与策略

Analysis method and strategy of 4G capacity expansion in metro

在现有地铁4G室内分布系统覆盖基础上,对地铁场景下的现网小区用户分布情况、市场占有率、4G终端占比、RRC平均用户数、业务激活比例等多维数据源进行综合分析,分别从用户驻留、业务接入、业务体验3个维度给出地铁场景下的扩容分析方法,并建立相应的扩容策略,可有效为专业设计人员对4G地铁扩容预测分析方法和解决策略提供相应参考与指导。

Based on the coverage of 4G cellular network in the metro indoor distribution system,the multi-dimensional data sources such as user distribution,market share,proportion of 4G terminals,average number of RRC subscribers and service activation ratio under the scenario of metro were analyzed comprehensively. The method of capacity expansion under the scenario of metro was presented from the three dimensions of user presence,service access and service experience. Meanwhile,the capacity expansion strategy was established,which could effectively provide reference and guidance for professional designers to analyze and predict 4G cellular wireless network capacity expansion under the scenario of metro.
