There are possibility that paging can be missed at UE side, did they have any provision to handle this at RAN side? can they re transmit it ?
I think paging retransmission is done from MME side. From MME side- MME has a timer T3413 for paging messages.If its not receive S1AP initial message after sending Paging messages ,T3413 expires then the MME will resend the paging message to the UE.
How last serving gNB sends paging message to UE when UE in RRC Inactive state?Because UE will be moving across gNB while inactive and how RAN based paging works in this scenario?
