The location of a UE in ECM-IDLE state is known by thenetwork on a Tracking Area List granularity. A UE in ECM-IDLEstate is paged in all cells of the Tracking Areas in which it is currentlyregistered. The UE may be registered in multiple Tracking Areas. All thetracking areas in a Tracking Area List to which a UE is registered are servedby the same serving MME.这是401里的一句话。
“The UE may be registered in multiple Tracking Areas”。这句话不知道是什么意思哦。。。一个CELL只能属于一个TA，一个UE在一个时刻只能在一个CELL里，这里怎么说一个UE可以同时在多个TA里注册呢？
