METHOD FOR SUPPORTING ACKNOWLEDGED TRANSPORT LAYER PROTOCOLS IN GPRS/EDGE HOST APPLICATION

摘要

A method for sending acknowledged transport data between a mobile station (202) and a base station system (208) in a GPRS system (200) in which a protocol control unit (214) counts the number of data blocks in an acknowledgement message sent by the mobile station in response to a data packet transmission. A heuristic is then defined, based on the number of data blocks counted, and the number of corresponding data blocks corresponding to a subsequent data packet transmission is compared with the heuristic to determine that a virtual acknowledgement channel is being requested when the number of corresponding data blocks in the subsequent packet data transmission is less than the heuristic.
