Title: RANDOM ACCESS METHOD, DEVICE AND COMMUNICATIONS SYSTEM
Abstract:
A random access device and a communications system, the random access device comprising: a first sending unit, the first sending unit being used for sending at least one third message according to a plurality of second messages which is returned by a network side. Thus, after a user equipment (UE) initiates a random access process to the network side, the plurality of second messages which is returned by the network side may be received so as to send a third message according to a second message, and carry out a subsequent random access process. In this way, the UE may carry out a plurality of random access attempts in parallel, which may improve the success rate of UE random access and reduce UE random access delays.
