    • A CDMA communication system transmits packet data via a designated forward channel which uses a particular spreading code, in the case where a base station has the packet data to send to a mobile station while the mobile sation does not have a dedicated channel established. A base station includes a first channel transmitter for transmitting a control message including information representative of a spreading code for designating a specific forward common channel to a specific mobile station, to the mobile station via a forward common channel, and a second channel transmitter for spreading user data with the spreading code upon reception of a response to the control message and transmitting the spread user data. A mobile station includes a control message analyzer for analyzing a message including information representative of a designated spreading code received via a forward common channel, and a forward common channel receiver for despreading user data spread with the designated spreading code generated based on the information, using the spreading code.

    • 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.
    • 提供了一种用于在CDMA移动通信系统中在基站与移动台之间发送分组数据的状态同步方法。 在一种方法中,基站在活动状态下向移动台发送状态检查消息。 基站从移动台接收响应消息,分析接收到的响应消息以确定移动台的状态。 基站终止对应的信道并转移到移动台的状态。 在CDMA移动通信系统中,在基站与移动台之间发送分组数据的第二种方法中,移动台在活动状态下向基站发送状态检查消息。 移动台从基站接收响应消息,分析接收到的响应消息以确定基站的状态。 移动台终止对应的信道,并将移动台转换到基站的状态。
