Abstract
State synchronization methods for transmitting packet data between a base station and a mobile station in a CDMA mobile communication system are provided. In one method, the base station transmits a state check message to the mobile station in an active state. The base station receives a response message from the mobile station, and analyzes the received response message to determine a state of the mobile station. The base station terminates a corresponding channel and transitions to the state of the mobile station. In a second method for transmitting packet data between a base station and a mobile station in a CDMA mobile communication system, the mobile station transmits a state check message to the base station in an active state. The mobile station receives a response message from the base station and analyzes the received response message to determine a state of the base station. The mobile station terminates a corresponding channel and transitions the mobile station to the state of the base station.
