A method for preventing a collision among access requests made from a plurality of mobile stations requesting access to a base station in a radio communication system having a plurality of forward link and reverse link access channels. The base station allocates one of the forward link channels as a broadcast channel and transmits channel information about currently available reverse link access channels to the mobile stations via the broadcast channel. Based on the channel information received via the broadcast channel, one or more of the mobile stations transmits an access request signal to the base station via a selected one of the currently unoccupied reverse link access channels. Upon receipt of an access approval signal from the base station, the access requested mobile station accesses the base station via the selected unoccupied access channel.
