Disclosed is a method for providing time information in an asynchronous mobile communication system. The method includes the steps of, upon receiving a location registration request from a mobile station (302), detecting a location shift of the mobile station and performing location registration depending on the detection result (304); determining whether to transmit the time information to the mobile station depending on the location shift of the mobile station (310); and upon determining to transmit the time information to the mobile station, generating a string message corresponding to the time information (318) and transmitting the string message to the mobile station (320).
The mobile station acquires the time information from the received string message (322) and controls its local time using the acquired time information (330). The string message can be a USSD, and the time information can be transmitted only when the location registration message is initially transmitted to the VLR. |
