NEW QUESTION 40
Regarding the analysis of the signaling process before the call drop, which of the following descriptions is wrong?
- A. If the UE handover occurs before the call drop, and the UE sending the reconfiguration message completely and until the call drop has not received any signaling issued by eNodeB, eNodeB may have received and issued new RRC establishment procedure, However, E is not received. Because the signaling message adopts the AM mode, it needs to receive the acknowledgement of the AM mode data by the receiving end within a certain period of time, and finally the RLC unrecoverable error occurs in the RLC layer of the UE.
- B. If the RRC connection reestablishment process occurs because the radio link fails before the call is dropped, the downlink quality of the dropped area is degraded. It is recommended to check the coverage, interference, and neighboring area mismatch.
- C. If handover occurs before call drop, and the UE sending the reconfiguration message completely has not been received any signaling issued by eNodeB until the call drop, reconfiguration complete message eNlodeB may not receive, so the timer releases link after a timeout.
- D. If the eNodeB detects the uplink out-of-step of the terminal before the call drop, the uplink quality of the dropped area is deteriorated. It is recommended to check for coverage, interference, neighboring area mismatch, power parameter settings, etc.
Answer: A
