1、同异频切换的参数配置A1 事件：事件进入条件：Ms - Hys Thresh停止异频测量门限：Threshold th2a for RSRP(Threshold2a)A1 迟滞：Related hysteresis of threshold th2a for RSRP (hys threshold2a)服务小区的 RSRP- hys threshold2a Threshold2a，且保持时间超过a1TimeToTriggerDeactInterMeas 的设置时间，则停止异频测量。A2 事件：启动同频测量门限 threshold1 事件进入条件：Ms + Hys Ms + Ofs + Ocs
2、+ Off 事件离开条件：Mn + Ofn + Ocn + Hys 服务小区的 RSRP+ a3Offset ，由于 hysA3Offset 配置为 0，故 A3 事件的示意图如下图所示：异频 A3 事件异频 A3 偏置 A3 offset RSRP inter frequencya3OffsetRsrpInterFreq 异频 A3 报告时长：A3 report interval RSRP inter frequency异频 A3 触发时延：A3 time to trigger RSRP inter frequency异频 A3 迟滞：Related hysteresis offset a3
3、offset RSRP inter frequencyhysA3OffsetRsrpInterFreq 异频 A3 事件满足：邻小区的 RSRPhysA3OffsetRsrpInterFreq 服务小区的 RSRP+ a3OffsetRsrpInterFreqA5 事件：事件进入条件：Ms + Hys Threah2诺西无 Ofn/Ocn 参数同频 A5 事件：Thresh1:Threshold th3 for RSRP(threshold3 )Thresh2 :Threshold th3a for RSRPthreshold3a A5 报告时长 A5 report intervalA5 触发
4、时延 A5 time to triggerA5 迟滞 Related hysteresis th3 and th3a for RSRP同频 A5 事件满足：当服务小区的RSRP+hysThreshold3threshold3a由于现网中的迟滞配置为 0，故只要服务小区低于 threshold3，邻区高于threshold3a，并达到触发的时间，就会发生切换，其示意图如图所示：异频 A5 事件：Thresh1:Threshold th3 for RSRP inter frequency（threshold3InterFreq ）Thresh2 :Threshold th3a for RSRP inter frequency（threshold3aInterFreq ）A5 报告时长 A5 report interval inter frequencyA5 触发时延 A5 time to trigger inter frequencyA5 迟滞 Related hysteresis of thresholds th3 and th3a for RSRP （hysThreshold3InterFreq ）
