摘要
为了解决东莞市地铁开通后客户流量迅速增长以及运营商实施提速降费策略后无线网络流量需求暴增,导致乘客在乘坐地铁时上网感知较差的问题,针对该市地铁的通信网络结构特点,采用重耕A频方式快速改造提升4G网络容量。方案利用原有RRU、BBU等设备,采用在POI至RRU间新增馈线的方法快速重耕A频,并根据市场部商用终端灵活适配优化参数策略。经网络管理性能统计数据验证,该方案能有效缓解网络拥塞、快速提升4G容量和用户上网感知速率。
In order to solve the poor user experience of mobile network for passengers in Dongguan subway, which is caused by rapid traffic growth and price adjustment strategy of operator. In the solution, the refarming of A frequency is adopted to upgrade the 4G network capacity rapidly according to the characteristics of communication network situation in subway. The refarming is deployed just by reutilizing the old equipment such as RRU & BBU and then by adding feeders between POI and RRU. After that, flexible parameter optimization strategy is configured according to the mobile terminals statistics in marketing. The network performance statistics proves that the solution can effectively alleviate network congestion, rapidly improve 4G capacity and user experience.
