Abstract:
1. A method for improving a data processing speed in a mobile communication system employing a High Speed Downlink Packet Access (HSDPA), the method comprising the steps of: a) producing a data unit for HSDPA services by inserting a header padding field into a header of the data unit; b) transmitting the produced data unit; and c) determining if the header padding field is to be inserted into the header of the data unit, wherein step c) includes the steps of: c-1) determining an effective field length of the header of the data unit; and c-2) determining if effective field length of the header of the data unit is a multiple of n bits so that the effective field length of the header can be divided on the same basis as the length of a payload of the data unit, and wherein when receiving the data unit, a user equipment (UE) determines if the effective field length of the header of the received data unit is a multiple of n bits, and if the effective field length of the received data unit is not a multiple of n bits, the UE extracts the payload of the received data unit, after removing the header padding field from the header of the received data unit, and transfers the extracted payload to an upper layer.
