端到端的LTE网络切换优化探讨

摘要

Handoff is a vital link for the mobile communication network. Negative inlfuence brought by excessive handoff failure should be avoided. To create better network experience, optimize network handoff, the paper analyzed the LTE handoff optimization method from end-to-end. First, it analyzed KPI index from network side, such as interference, X2 and S1 proportion, early and late handoff, preparation success rate, etc., and then it discussed the issue from the user perception MR aspects, such as RSRP, RSRQ, TA, unbalanced up-down line, etc., providing reference for LTE handoff optimization.%对于移动通信网络，切换是一个至关重要的环节，应避免过多的切换失败对网络带来的负面影响。为了创造更好的网络体验，优化网络切换，从端到端分析LTE切换优化方法。首先从干扰、X2和S1占比、早切换和晚切换、准备成功率等网络侧KPI指标分析研究，再从RSRP、RSRQ、TA、上下行不平衡等基于用户感知的MR方面进行探讨，为LT E切换优化提供参考。
