Abstract

The invention discloses a method for reset control of radio link control entity which comprises: setting a corresponding discard timer for each Packet Data Convergence Protocol service data unit (PDCP SDU) on Packet Data Convergence Protocol (PDCP) layer; starting the discard timer when the upper layer of the PDCP layer transfers the PDCP SDU; stopping the discard timer, setting and starting an RLC reset timer when a first predetermined condition is fulfilled, and triggering the reset procedure of the RLC entity when a second predetermined condition is fulfilled. The first predetermined condition is: the PDCP SDU has been transferred to the RLC layer and the RLC sequence number has been assigned before the discard timer expires. The second predetermined condition is: when the RLC reset timer expires, there exist RLC PDUs which are not transferred successfully among all of the RLC PDUs.

Description

technical field

[0001] The invention relates to the technical field of digital mobile communication, in particular to a reset control method of a wireless link control entity in a wireless communication system. Background technique

[0002] The radio link control layer (Radio Link Control, referred to as RLC) of the wireless interface of the third generation mobile communication system Wideband Code Division Multiple Access (WCDMA for short) includes three modes of RLC entities: transparent mode ( Transparent Mode, TM for short), Unacknowledged Mode (UM: Unacknowledged Mode, UM for short), and Acknowledged Mode (AM). The TM RLC entity and the UM RLC entity can be configured as a sending RLC entity or a receiving RLC entity. When sending an RLC entity, a Radio Link Control Protocol Data Unit (Radio Link Control Protocol Data Unit, RLC PDU for short) is sent, and the receiving RLC entity receives an RLC PDU. . The AM RLC entity includes a sending end and a receiving end, whe...
