Method and apparatus for improving a mobile station cell change operation in the general packet radio system (GPRS)

摘要

A mobile station executed method, wherein upon changing from a current cell to a new cell in a wireless packet data network the mobile station enters the new cell; generates a cell change packet data unit (PDU) message for informing the network of the location of the mobile station in the new cell; buffers the cell change PDU message into a PDU transmit queue before any buffered PDUs that were present before the mobile station entered the new cell; and transmits the buffered cell change PDU before any of the buffered PDUs that were present before the mobile station entered the new cell.

1. A method, comprising:
generating a cell change logical link control (“LLC”) packet data unit (“PDU”) for informing a network of a location of a mobile station in a new cell; buffering the cell change LLC PDU into a LLC PDU transmit queue such that the cell change LLC PDU is selected for transmission prior to any other buffered packet data units that are present in the LLC PDU transmit queue when the cell change LLC PDU is buffered; and transmitting the buffered cell change LLC PDU before any of the other buffered packet data units that are present in the LLC PDU transmit queue when the cell change LLC PDU is buffered.
