A base station and a base station controller are used for providing data communication channels using random access (RACHs) for mobile stations. The base station or the base station controller provides for notifying channel information on an RACH. Each mobile station provide for determining whether or not a packet can be sent and for shifting from one RACH to another based on the channel information. The base station and the base station controller further provide for transferring a packet to a mobile station over the RACH. The base station controller provides for terminal identifier management and packet division and reconstruction for transferring a packet between mobile stations or between a mobile station and the LAN.
