一种基于S1-MME信令的CSFB寻呼优化

摘要

TD-LTE系统是纯IP网络，话音解决方案有单卡双待和话音回落两种，话音回落方案对终端电池的续航能力有较大提升。本文重点介绍TD-LTE系统话音回落的寻呼优化，针对寻呼过程中影响成功率的末端原因进行逐一分析定位，对失败占比较大的寻呼无响应、TAU、干扰进行了详细的分析并给出优化建议。%TD-LTE system is a pure IP network, voice solutions with a single card dual standby and voice dropped two, endurance voice down scheme of terminal battery is greatly improved. This paper focuses on the optimization of TD-LTE system for speech paging fall. By analyzing the reasons for affecting the positioning terminal paging process success rate, the failure to account for the relatively large non response paging, TAU, interference is analyzed in detail and gives suggestions for optimization.
