1. A method for processing random access, comprising:
receiving, by a base station, a random access request sent by a user equipment (UE), wherein the random access request comprises a preamble;
generating, by the base station, a random access response message, wherein in response to a length of a random access response window being greater than a preset length threshold, the random access response message comprises indication information, and in response to the length of the random access response window being not greater than the preset length threshold, the random access response message does not comprise the indication information, wherein the indication information is configured to indicate a sending position where the preamble corresponding to a scheduling random access radio network temporary identifier (RA-RNTI) of the random access response message is sent, wherein the scheduling RA-RNTI of the random access response message corresponds to multiple sending positions in response to the length of the random access response window being greater than the preset length threshold; and
sending, by the base station, the random access response message to the UE.
