質問 37
Regarding the T310 timer, which of the following descriptions is wrong?
- A. Receive N311 continuous synchronization, indication from the lower layer, trigger the corresponding handover process, and stop when initializing the connection re-establishment process
- B. If the security is not activated after the timer expires, the RRC enters idle state, otherwise, the RRC connection establishment process is initiated.
- C. During the operation of the T310 timer, if the wireless link recovers, stop the timer, otherwise it will run all the time. Once the timing expires, the wireless link is considered to be failed.
- D. When the physical layer problem is detected, it is turned on, that is, the receiving the indication that N310 is continuously out of sync, and from the lower layer.
正解: B
