SYSTEM AND METHOD FOR AVOIDING STALL USING TIMER FOR HIGH-SPEED DOWNLINK PACKET ACCESS SYSTEM |
摘要 |
A method for preventing a stall condition in a terminal of a mobile communications system uses a timer to limit how long data blocks are stored in a reordering buffer. The method includes receiving a data block over a wireless link, determining whether a preceding data block has not been received, storing the received data block in the reordering buffer if a preceding data block has not been received, and then outputting the received block from the buffer when the timer expires. Whether or not a preceding data block is missing is determined based on a comparison of transmission sequence numbers. In other steps of the method, succeeding data blocks are output from the buffer based on expiration of a second timer period. The periods of the timer are advantageously controlled to prevent a wrap-around of transmission sequence numbers with respect to data blocks stored in the buffer. |
