Example Embodiment

[0032] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention clearer and clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention, but not to limit the present invention.

[0033] figure 2 It is a schematic diagram of a structure in an evolved base station according to an embodiment of the present invention. Such as figure 2 As shown, the base station eNodeB may include: DRX module 1 and TA module 2, where the DRX module 1 is used to maintain the start and stop of DRX timers and the state transition of the UE, and at the same time maintain the UE’s non-scheduled data time counter and the UE in DRX inactive time counter; TA module 2, used to maintain the TATimer timer, obtain related configuration information and UE stat...

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...
