Patent ID: 7499424

Claim:
A method of efficiently providing transmission power status information (TPS) and buffer occupancy information (BO) of a user equipment (UE), in a mobile communication system, the method comprising the steps of: confirming whether an amount of data to be transmitted by the UE exceeds a preset threshold value; if the amount of data exceeds the threshold value, including the TPS and the BO of the UE in a protocol data unit (PDU) of a media access control layer (MAC-e); reporting a start of a packet data service by transmitting the MAC-e PDU that comprises the TPS and the BO of the UE to a Node B through a MAC-e signaling; and reporting an occurrence of an indicator that indicates an end of the TPS transmission to the Node B through a MAC-e signaling if the amount of data to be transmitted by the UE is less than the threshold value.
