Abstract

The invention provides a method and system for improving the data transmission performance. The method for improving the data transmission performance comprises the steps that a wireless resource control layer on a user side reports a measurement report, and a wireless link control layer on the user side is informed to conduct process switching at any moment; after the wireless link control layer on the user side receives an instruction of the wireless resource control layer on the user side, an uplink is triggered to send an uplink state packet and a P position data packet; after uplink resources distributed by a network are received, a user sends the measurement report, the uplink state packet and the P position data packet to a network side; a source base station on the network side conducts process switching according to the measurement report, confirms and releases a downlink data packet according to the uplink state packet and returns the downlink state packet to the user side according to the P position data packet; the user side confirms and releases the uplink data packet according to the downlink data packet. According to the method and system for improving the data transmission performance, uplink data packets and downlink data packets which are successfully sent are confirmed as many as possible before switching, and the probability of ineffective re-transmission of several packets during switching is reduced.

Description

technical field [0001] The present invention relates to the field of wireless technology, in particular to a method and system for improving data transmission performance. Background technique [0002] 3GPP (3Generation Partnership Project) protocol 36.323sec5.2.1.1 stipulates that when the upper layer requests a PDCP (Packet Data Convergence Protocol) reconstruction, the UE (user) shall: reconstruct the uplink header compression protocol (if configured); During the reconstruction process, the encryption algorithm and the key provided by the upper layer are used for encryption; starting from the first PDCP SDU for which the corresponding PDCP PDU is successfully delivered but not acknowledged by the lower layer, before PDCP reconstruction as described below, all Starting from the COUNT value corresponding to this PDCP SDU, retransmission or transmission of the PDCP SDUs corresponding to the PDCP SN values ​​arranged in ascending order of the COUNT value. [0003] 3GPP (3Gen...
