An access request message transmission device for a mobile station in a CDMA
communication
system employing RSMA in which a base station assigns a reverse common channel
in response to an access request message from the mobile station, and the mobile
station transmits a message to the base station over the assigned reverse common
channel. The access request message transmission device includes a hash ID generator
for generating a multi-bit hash ID for exclusively using the reverse common channel;
a traffic information generator for generating multi-bit traffic information representing
traffic information on the reverse common channel; and an access channel transmitter
for generating the access request message using the hash ID and the traffic information,
and transmitting the generated access request message to the base station over
an access channel.
