Problems solved by technology

It is understandable that when the DRX cycle is too short, the scheduling opportunity of the UE can be guaranteed, but the frequent detection of the channel by the UE will increase the power consumption of the UE
When the DRX cycle is too long, it can effectively reduce the power consumption of the UE, but there will be too long a delay for the paging of the UE to be responded by the UE, resulting in a decrease in system performance

Embodiment Construction

[0040] The application scenarios of the present invention and the technical solutions in the embodiments will be described below with reference to the accompanying drawings.

[0041] Such as figure 1 As shown, the user equipment UE accesses the IMS network through a radio access network (RadioAccessNetwork, referred to as) and a core network (CoreNetwork, referred to as CN). The technology described in the present invention can be applied to a Long Term Evolution (LTE for short) system, or a wireless communication system using various wireless access technologies, such as code division multiple access, frequency division multiple access, time division multiple access, orthogonal frequency Access technology systems such as division multiple access and single carrier frequency division multiple access. In addition, it can also be applied to a subsequent evolution system using the LTE system. For the sake of clarity, only the LTE system is taken as an example for description he...

Abstract

The present invention relates to the technology for managing discontinuous reception (DRX). According to the service type of UE, the DRX cycles with different cycle lengths are configured. When the initiation of a voice service by user equipment (UE) is identified, a short first DRX long period is configured for the UE or the UE is indicated to activate the DRX. When the condition that the UE does not initiate the voice service is identified, a second DRX long period is configured for the UE. The UE carries out corresponding receiver switch control according to the configured DRX long periods so as to receive downlink data or go to sleep. Through the scheme provided by the invention, the DRX period of the UE can be flexibly configured, and thus the better balance between UE power consumption saving and user experience improvement is obtained.

Description

technical field [0001] The present invention relates to the field of mobile communication, in particular to a discontinuous reception (Discontinuous Reception, DRX for short) technology in a wireless communication system. Background technique [0002] VoLTE (Voice over LTE) technology is a voice solution based on IP Multimedia Subsystem (IP Multimedia Subsystem, IMS for short). VoLTE technology can not only improve the utilization rate of wireless spectrum, reduce the network cost of operators, but also greatly improve user experience. Using VoLTE technology, users can wait for a shorter time and enjoy higher-quality, more natural audio and video call effects. [0003] With the widespread application of smart terminals, in order to reduce power consumption of terminals, such as user equipment (User Equipment, UE for short), DRX technology is introduced. The cycle of DRX indicates when the UE needs to monitor the channel and when the UE needs to turn off the power to save b...
