通过对小区寻呼容量和LAC(位置区码)区容量的计算和分析,结论是:PS(分组交换)域业务引入后,同等情况下,小区的PCH(寻呼信道)负荷大幅增加,同一LAC支持的最大CS(电路交换)话务量减小;可以通过把同一LAC区划分成多个RAC(路由区码)区的形式,来减少PS域业务引入后对CS域的寻呼影响。
Through the calculation and analysis of cell paging capacity and LAC area capacity, the conclusion is: After the introduction of the PS (packet switched) domain service, under the same circumstances, the PCH (paging channel) load of a cell increases substantially, and the same The maximum CS (circuit switched) traffic supported by the LAC is reduced. You can reduce the paging impact on the CS domain after the PS domain service is introduced by dividing the same LAC area into multiple RAC (Routing Area Code) areas.
