Processing method and device capable of keeping uplink synchronization of terminals in DRX mode

Abstract

The invention discloses a processing method and a device capable of keeping uplink synchronization of terminals in a DRX (discontinuous reception) mode, wherein the processing method comprises the following steps: recording the first time length that a terminal does not execute data scheduling through a first counter in a base station; and judging whether the first time length is larger than a first threshold value, wherein when the first time length is larger than the first threshold value, the base station does not send a timing advance TA (time alignment) command; and when the first time length is smaller than the first threshold value, the base station can determine to sent a TA command according to the result of comparing the timing length of a TA timer with the period length of DRX (discontinuous reception). According to the processing method, UE (user equipment) can flexibly keep synchronization with the uplink of the base station at the same time of the realization of the DRX configuration, and meanwhile, the happening of the uplink out-of synchronization is reduced to the maximum extent, and the utilization rate of system resources is optimized.

Description

technical field [0001] The present invention relates to the communication field, in particular, to a processing method and device for maintaining uplink synchronization of a terminal in DRX mode. Background technique [0002] In the third-generation mobile communication Long Term Evolution (LTE for short) system, in order to save the battery consumption of the User Equipment (UE for short, also called the terminal), the system configures Discontinuous Reception (Discontinuous Reception, referred to as DRX) function. DRX can make the UE stop monitoring the physical downlink control channel (Physical Downlink Control Channel, PDCCH for short) within a certain period of time. [0003] The DRX cycle (DRX Cycle) refers to the periodic repetition of the duration (OnDuration) and the inactive time (Inactive). [0004] The OnDuration Timer (OnDuration Timer) defines the number of subframes that the UE needs to continuously monitor the PDCCH at the beginning of the DRX cycle. [0...

AI Technical Summary

Problems solved by technology

[0009] The main purpose of the present invention is to provide a processing method and device for a terminal to maintain uplink synchronization in DRX mode, so as to solve the problem in the prior art that when the UE is configured with DRX, when the TATimer time period expires and a TA command needs to be sent, due to The UE is not in the active time, causing the UE to fail to receive TA commands and enter the uplink out-of-sync state
