Embodiment Construction

[0041] In order to solve the problem in the prior art that the quality of data transmission is degraded due to enabling the CDRX function, the embodiment of the present invention conducts a detailed study on the CDRX execution process of the existing solution.

[0042] Firstly, the existing CDRX execution process is introduced.

[0043] The CDRX execution process is to make the terminal enter the DRX sleep period when there is no data transmission, and re-enter the DRX activation period when there is data to be transmitted, so as to reduce the power consumption of the terminal. After receiving the radio resource control protocol (Radio Resource Control, RRC) reconfiguration message issued by the base station, the terminal reads the CDRX parameters, and then the terminal periodically monitors the PDCCH according to the established rules to configure only one CDRX cycle CDRX execution process For example, CDRX parameters include:

[0044] On Duration Timer: An activation timer,...

Abstract

The invention discloses a method and device for controlling discontinuous reception in order to solve a problem that data transmission quality is decreased due to fact that a CDRX function is started. The method of the invention comprises steps of obtaining a parameter value characterizing quality of the current channel when discontinuous reception CDRX cycle is started under a state that a radio resource control protocol which is indicated by a network side RRC _CONNECTED is connected, and extending monitoring time for a physical downlink control channel-PDCCH channel in a CDRX cycle when the parameter value is greater than a first preset threshold value.

Description

technical field [0001] The present invention relates to the technical field of mobile communication, in particular to a control method and device for discontinuous reception. Background technique [0002] In the long-term evolution (ong Term Evolution, LTE) system, the terminal obtains the wireless resource information for sending or receiving the uplink and downlink data packets by monitoring the Physical Downlink Control Channel (PDCCH), and the continuous monitoring of the PDCCH will aggravate the power consumption. Considering that the transmission of uplink and downlink data packets in the LTE system is generally bursty, if the terminal can monitor the PDCCH when there is data transmission, and stop monitoring the PDCCH when there is no data transmission, the power of the terminal can be greatly reduced. consumption. In view of this feature, in the LTE system, a discontinuous reception (Discontinuous Reception, DRX) function is configured for a terminal in a radio res...
