<p>A method for radio link control entity reset is provided, it includes: a Timer_Discard timer is set respectively for each Packet Data Convergence Protocol Service Data Unit, and the corresponding Timer_Discard timer is started when an upper layer of the Packet Data Convergence Protocol forwards a Service Data Unit; in the case of the started Timer_Discard timer overtime, if the Service Data Unit corresponding to the started Timer_Discard timer has been forwarded to a Radio Link Control entity and has been assigned a Radio Link Control sequence number, then a Radio Link Control Timer_RST timer is started; in the case of the started Timer_RST timer overtime, if not all the Protocol Data Units related to the Service Data Unit are sent successfully, then the Radio Link Control reset procedure is started. The present invention can prevent from buffer overload and radio resource waste and unfairness caused by immediately discarding the Service Data Unit, and can simplify the processing mechanism, it can reduce the number of timers, and can lessen processing complexity and overhead.</p> |
