In LTE,suppose RLF Is occurs then how we know about RLF?

Question

If after attach procedure suddendly enodeb shut down then how mme will know about enodeb?

Answer 1

Hi,
To be honest there is no clear way explained in specs regarding RLF, and there is no way "we" can detect whether RLF has happened or not. but UE can detect RLF if:
1. RSRP value too low.
2. UE failed to decode PDSCH and PDCCH

Someone ask me, through which message ue know about the rlf??
