The invention discloses a transmission method of CDMA base station system and its message, the method comprises the following steps: a user terminal from DO? AN to switch to the same packet control function under PCF 1x? BS PCF DO AN; to send? Used to inform the user terminal in 1x? BS in the establishment and / or release data a notification message service which is used to inform the user terminal in 1x? PCF carrying the currently selected packet data service node PDSN address information notification message establishing data service in BS; DO? AN receives the notification message according to the notification message update local storage and PDSN address information corresponding to the user terminal. The invention solves the problem of abnormal interaction with PDSN when data service change occurs between 1xBS and DO and AN in the same PCF, thereby improving the stability of the system.
