摘要
LTE网络驻留指标直观表征LTE用户接入并驻留在LTE网络内使用业务的情况。通过深入分析基于LTE系统的信令流程,针对网络互操作的各个场景在EPC网络各接口信令流程的特征,梳理出分场景的指标算法规则,提出一种简单有效的基于LTE网络信令的驻留时长指标算法。利用该指标可开展2G/3G/4G网络互操作问题分析定位,指导LTE网络优化工作。
The LTE network resident indicators （ICTs） directly characterize the situations of LTE users access and reside in LTE networks. The signaling process of LTE systems was analyzed in depth firstly. Secondly, the characteristics of each network interoperability scenarios in each interface signaling process in EPC network were given. Then, the rules of sub-scenario index algorithm were summarized. A simple and effective signaling based resident time index algorithm for LTE network was proposed. The indicator can be used to analyze and locate 2G/3G/4G interoperability as well as guide the LTE network optimization.
