Abstract
There are provided a common channel message communicating device and method in a CDMA communication system. In a base station of the common channel message communicating device a control message generator (612) generates a control message including information representative of a spreading code for spreading a reverse common channel message and a forward common channel transmitter (618) transmits the control message on a forward common channel. In a mobile station a control message analyser analyses information representative of an assigned spreading code included in the control message received on the forward common channel a spreading code generator generates a spreading code based on the spreading code information and a channel transmitter spreads the reverse common channel message by the spreading code and transmits the spread reverse common channel message.

60. A common channel message communicating method in a CDMA communication system, comprising the steps of: 2 o causing a base station to generate a control message including information WO 99/49597 PCT/KR99/00141 - 47 representative of a spreading code for spreading a reverse common channel message; causing the base station to transmit the control message on a forward common channel; 5 causing a mobile station to analyse the information representative of an assigned spreading code included in the control message received on the forward common channel; causing the mobile station to generate a spreading code based on the spreading code information; and 10 causing the mobile station to spread the reverse common channel message by the spreading code and transmit the spread reverse common channel message.
61. The method of claim 60, wherein the spreading code information is used for the mobile station exclusively to communicate with the base station when the mobile station spreads the reverse common channel message. 15
62. The method of claim 61, wherein the spreading code information is an access channel number.
63. The method of claim 62, further comprising the step of causing the base station not to assign the same access channel number to a different mobile station while the mobile station uses the access channel number. 20
