1. An apparatus for making a plurality of terminals have a random access to the reverse common channel of a base station in CDMA, comprising:

  • code synchronization detection information broadcast means provided in said base station for broadcasting the state information of a channel card in real time for said terminals to recognize the code synchronization detection when the code synchronization of a certain data is acquired through performing the code synchronization of the preambles transmitted from said terminals through said reverse common channel; and

    data transmission determination means provided in said terminals for making the terminals to have attempted data transmission in the same time slot with the data of said code synchronization detection continue data transmission and the other terminals stop data transmission.
