Abstract
A method for controlling channel access in a mobile communication system. A base station generates a broadcast channel frame, which includes status information indicating whether channel codes which are changing in real time are occupied or not. The base station transmits the broadcast channel frame at predetermined intervals. Then, a mobile station selects an available channel code based on information from the received broadcast channel frame, generates a channel assignment request message, and transmits the channel assignment request message on a random access channel. Upon reception of the channel assignment request message on the random access channel, the base station assigns a channel, sets a transmission rate, and transmits the information on a forward access channel.
