Abstract
Disclosed are a method for distributing a random access and a method for distributing and performing the random access. According to the present invention, a method for performing a random access of a terminal comprises the step of receiving a paging message indicative of a network reentry from a base station, wherein said paging message can contain at least either the identifier information of terminal groups, in which terminals are grouped, or the random access configuration information which corresponds to said terminal groups. Said random access configuration information can contain random access standby time information of said terminal groups and back-off window size information. Said method further comprises the steps of: selecting a random access opportunity on the basis of said random access configuration information; and transmitting a random access code to said base station in said selected random access opportunity.
