Event A1 (Serving becomes better than threshold)
:表示服务小区信号质量高于一定门限,满足此条件的事件被上报时,eNodeB停止异频/异系统测量;类似于UMTS里面的2F事件;


Event A2 (Serving becomes worse than threshold)
:表示服务小区信号质量低于一定门限,满足此条件的事件被上报时,eNodeB启动异频/异系统测量;类似于UMTS里面的2D事件;


Event A3 (Neighbour becomes offset better than serving)
:表示同频/异频邻区质量高于服务小区质量,满足此条件的事件被上报时,源eNodeB启动同频切换请求;一般来说是基于覆盖的切换


Event A4 (Neighbour becomes better than threshold)
:表示异频邻区质量高于一定门限量,满足此条件的事件被上报时,源eNodeB启动异频切换请求;一般来说是基于负荷均衡的切换


Event A5 (Serving becomes worse than threshold1 and neighbour becomes better than threshold2)
:表示服务小区质量低于一定门限并且邻区质量高于一定门限;类似于UMTS里的2B事件;


Event B1 (Inter RAT neighbour becomes better than threshold)
:表示异系统邻区质量高于一定门限,满足此条件事件被上报时,源eNodeB启动异系统切换请求;类似于UMTS里的3C事件;


Event B2 (Serving becomes worse than threshold1 and inter RAT neighbour becomes better than threshold2)
:表示服务小区质量低于一定门限并且异系统邻区质量高于一定门限,类似于UMTS里进行异系统切换的3A事件。
