id='REI-00001' date='20231010' The present invention relates to aid='REI-00001' id='REI-00002' date='20231010' A id='REI-00002' preamble allocation method id='REI-00003' date='20231010' and a random access methodid='REI-00003' in a mobile communication systemid='REI-00004' date='20231010' . In the present invention,id='REI-00004' id='REI-00005' date='20231010' includes allocating id='REI-00005' one among preamble resources id='REI-00006' date='20231010' is allocatedid='REI-00006' to id='REI-00007' date='20231010' a id='REI-00007' specific mobile id='REI-00008' date='20231010' stationsid='REI-00008' id='REI-00009' date='20231010' station id='REI-00009' in advance, before random access. The mobile id='REI-00010' date='20231010' stations requestid='REI-00010' id='REI-00011' date='20231010' station requests id='REI-00011' random access by transmitting a preamble based on the pre-allocated preamble resource to a base station. id='REI-00012' date='20231010' It is therefore possible to preventid='REI-00012' id='REI-00013' date='20231010' A id='REI-00013' collision caused by id='REI-00014' date='20231010' the fact that other mobile stations transmit the same preambleid='REI-00014' id='REI-00015' date='20231010' the same preamble transmission by another mobile station may be preventedid='REI-00015' .
