Abstract
The present disclosure relates to a method and a device for responding to a random access. The method includes: a user equipment (UE) sending a random access request, wherein information including a UE identifier is carried in the random access request; and the UE receiving a random access response, wherein when UE identifier carried in the random access response is consistent with the UE identifier in the random access request, a contention resolution is completed; when the UE identifier carried in the random access response is inconsistent with the UE identifier in the random access request, the UE determines that the random access fails this time, and re-initiates a random access attempt; and when no UE identifier is carried in the random access response, the UE falls back to a random access process in which no UE identifier information is carried in the random access request.
