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.

1. An access request message formatting method for a mobile method for a mobile station in a CDMA (Code Division Multiple Access) communication system employing RSMA (Reserve Multiple Access) 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, comprising the steps of:generating a multi-bit ID for enabling the mobile station to exclusively use the reverse common channel; generating multi-bit traffic representing traffic information on the reverse common channel; generating CRC bits and tail bits; and scrambling said multi-bit traffic information; wherein the traffic information includes traffic transfer rate information, one-frame length information, and message length information. 2. The access request message formatting method as claimed in claim 1, wherein the ID is created with a hashed value of an electronic serial number (ESN).3. 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, comprising:an ID generator for generating a multi-bit 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; an access channel transmitter for generating the access request message using the ID and the traffic information, and transmitting the generated access request message to the base station over an access channel; and a scrambling circuit for scrambling said multi-bit traffic information; wherein the traffic information includes traffic transfer rate information, one-frame length information, and message length information. 4. The access request message transmission device as claimed in claim 3, wherein the access channel transmitter comprising a CRC generator and a tail bit generator, wherein the access channel transmitter creates an access request message comprised of the ID, traffic information, CRC bits and tail bits.5. The access request message transmission device as claimed in claim 3, wherein the ID generator creates the ID based on a hashed value of an ESN.6. An access request message transmission method 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, comprising the steps of:generating a multi-bit ID for exclusively using the reverse common channel; generating a multi-bit traffic information representing traffic information on the reverse common channel; generating the access request message using the ID and the traffic information; scrambling said multi-bit traffic information; and transmitting the generated access request message to the base station over an access channel; wherein the traffic information includes traffic transfer rate information, one-frame length information, and message length information.
