目前,若UE需求进行小区切换时,需要经过测量上报触发,测量结果上报,切换准备,切换命令下发,切换执行等过程,因此,UE进行小区切换时延较长,并且,小区切换时延较长可能导致小区切换过程中,UE在服务小区的信号质量较差,从而导
致发生RLF或接收不到切换命令,使得UE小区切换失败。
现有的小区切换的主要步骤包括:
(1)源基站向UE发送测量配置。
(2)UE根据源基站发送的测量配置进行测量,并在满足条件时上报测量报告。
(3)源基站与目标基站交互,并进行切换准备。
(4)UE接收源基站下发的切换命令,立即与源小区断开连接,并接入到目标小区。
下面对本申请实施例提供的小区切换方法、装置、用户设备及存储介质中涉及的一些概念和/或术语做一下解释说明。
1、事件触发的测量上报
通常,在测量配置中的reportType字段设置为eventTriggered时,UE可以基于配置的事件判决是否触发测量上报,如表1所示,事件主要分为以下9种:
表1
其中,Intra-RAT切换常用的事件为A3或A5事件,以A3事件为例,进入条件和离开条件的各参数含义如下:
Mn:邻小区测量结果,不考虑任何偏移。
Ofn:邻小区测量对象特定偏移量。
Ocn:邻小区小区级特定偏移量。
Mp:主服务小区(SpCell)测量结果,不考虑任何偏移。
Ofp:SpCell测量对象特定偏移量。
Ocp:SpCell小区级特定偏移量。
Hys:事件的滞后参数。
Off:事件的偏移参数。
为了避免乒乓切换,基站在测量上报配置中针对每一事件配置触发时间(timeToTrigger)参数。
(1)当一个或多个小区在timeToTrigger时间内的L3滤波信号质量都满足事件的进入条件时,UE将对应小区包含进小区触发列表(cellsTriggeredList),并触发上报。
(2)若上报配置中使能ReportOnLeave,则当cellsTriggeredList中的一个或多个小区在timeToTrigger时间内的L3滤波信号质量都满足事件的离开条件时,UE将对应小区从cellsTriggeredList中移除,并触发上报。
本申请实施例提供一种基于AI的小区切换方法,应用AI预测网络侧设备的服务小区和/或UE的邻小区在未来一个或多个时刻的信号质量,从而可以根据预测结果判断是否触发测量上报,并上报相关预测结果。
