标题[讨论] 关於LTE NAS layer spec的讨论
时间Sun Aug 5 04:00:39 2012
TS24.301 P32提到
The UEi shall mark the EPS security context on the USIM or in the
non-volatile memory as invalid when the UE initiates an attach procedure as
described in subclause 5.5.1 or when the UE leaves state EMM-DEREGISTERED for
any other state except EMM-NULL.
其中不太懂为啥UE离开EMM-DEREGISTERED
这样EPS security context就要是invalid..@@
欢迎有在研究LTE L2 L3的大大们一起讨论
