摘　　要：SA/NSA网络下,4G/5G互操作参数对终端驻留5G网络存在较大影响。5G信号不足时会回落4G,导致5G差样本数据未上报,通过5G CHR评估覆盖时无法发现问题,存在“覆盖虚高”现象。本文从终端驻留5G网络策略和产品CHR打点机制等方面分析,结合网络结构和用户行为等维度数据建模,旨在更加完整评估5G网络的覆盖水平,还原5G的真实覆盖。In 5G network,4G/5G interoperability parameters have a great impact on UEs camping on 5G networks.UEs always fall back to 4G networks when 5G signal is weak.As a result,weak 5G measurement samples are not reported,and problems cannot be detected during coverage evaluation based on 5G CHR,which will cause the evaluation of 5G coverage is falsely high.In this report we introduced a new way to comprehensively evaluate 5G network coverage and restore actual 5G coverage based on 5G network camping policy,CHR mechanism and user behavior.

关 键 词：异系统测量 CHR评估 5G真实覆盖
