随着移动用户的持续增长和手机新业务的不断推广,移动通信系统的寻呼负荷日益加重。以移动用户漫游被叫时的呼叫流程为例,分析IMSI寻呼和TMSI寻呼的原理,对比两种寻呼方式对网络性能影响,提出一种评估寻呼方式的量化计算方法。通过对寻呼容量较为紧张网元的试验证明,该方法可以科学指导寻呼方式的优化工作,提高移动通信网络的系统寻呼容量,改善移动通信系统寻呼性能。
With the continuous growth of mobile users and the continuous promotion of new cell phone services, the paging load of the mobile communication system is getting heavier and heavier. Taking the call flow when the mobile user roams the called party as an example, the principle of IMSI paging and TMSI paging is analyzed. Comparing the impact of the two paging modes on the network performance, a quantitative calculation method for evaluating the paging mode is proposed. Through the trial of the network element with relatively tight paging capacity, this method proves that this method can scientifically guide the paging optimization, improve the paging capacity of the mobile communication network and improve the paging performance of the mobile communication system.
