Patent ID: 7529271

Claim:
A method comprising: at a radio link control/medium access control protocol layer, receiving at least one logical link control packet data unit from an upper protocol layer, wherein each logical link control packet data unit belongs to a certain packet data protocol context associated with logical link control connection information and wherein quality of service information relating to the logical link control connection information is defined for the certain packet data protocol context, reordering each logical link control packet data unit the radio link control/medium access control protocol layer according to a relative urgency of transmission of the logical link control packet data unit with respect to a buffered logical link control packet data unit based on at least the logical link control connection information and the quality of service information, and delivering the received logical link control packet data unit and the buffered logical link control packet data unit further from the radio link control/medium access control protocol layer in reordered order, wherein the method is performed by a mobile station to transfer user data in a wireless packet data network.
