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;
? 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;
? 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。

楼上 A4是异频切换事件好吗?
