Abstract

The present invention relates to a technology for managing discontinuous reception (DRX). DRX cycles of different cycle lengths are configured according to service types of UE. If it is identified that the user equipment (UE) initiates a voice service, a relatively short first long DRX cycle is configured for the UE or the UE is instructed to deactivate DRX; and if it is identified that the UE does not perform a voice service, a relatively long second long DRX cycle is configured for the UE. The UE performs corresponding receiver on/off control according to the configured long DRX cycle, so as to receive downlink data or hibernate. According to the solution provided in the present invention, a DRX cycle of UE can be flexibly configured, so that a better balance between power consumption reduction of the UE and user experience improvement can be achieved.

Claims14

Dependent claims

A method for managing a discontinuous reception (DRX) cycle, wherein the method comprises:

identifying, by a base station, that a user equipment initiates a voice service;
and
in response to identifying that the user equipment initiates the voice service, configuring, by the base station, a long DRX cycle for the user equipment to be a first cycle length or instructing the user equipment to deactivate DRX, wherein the first cycle length is longer than a second cycle length for the long DRX cycle, the second cycle length corresponding to the long DRX cycle for a service other than the voice service performed by the user equipment when the user equipment does not perform the voice service;
wherein identifying that the user equipment initiates the voice service is based on:
detecting that there is a data packet transmitted on a signaling bearer of QCI=5;
detecting that a message sent on a signaling bearer of QCI=5 is a session initiation protocol (SIP) invite message;
detecting that a message sent on a signaling bearer of QCI=5 is an acknowledgement response message for an SIP invite message;
or
receiving a notification from a core network or an IP multimedia subsystem (IMS), wherein the notification indicates that the user equipment initiates the voice service.

6 more elements

A base station, comprising:

at least one processor, configured to:
configure a long discontinuous reception (DRX) cycle for a user equipment to be a first cycle length or instruct the user equipment to deactivate DRX in case the user equipment is identified as initiating a voice service;
and
configure the long DRX cycle for the user equipment to be a second cycle length for a service other than the voice service in case the user equipment is identified as not performing the voice service, wherein the first cycle length is shorter than the second cycle length;
and
a transmitter, configured to send the first cycle length, the second cycle length, or an instruction for instructing the user equipment to deactivate DRX;
wherein the at least one processor is configured to identify that the user equipment initiates the voice service based on:
detecting that there is a data packet transmitted on a signaling bearer of QCI=5;
detecting that a message sent on a signaling bearer of QCI=5 is a session initiation protocol (SIP) invite message;
detecting that a message sent on a signaling bearer of QCI=5 is an acknowledgement response message for an SIP invite message;
and/or
receiving a notification from a core network or an IP multimedia subsystem (IMS), wherein the notification indicates that the user equipment initiates the voice service.

9 more elements

A communications system, comprising:

a base station;
and
a user equipment;
wherein the base station is configured to:
configure a long discontinuous reception (DRX) cycle for the user equipment to be a first cycle length or instruct the user equipment to deactivate DRX in case the user equipment is identified as initiating a voice service;
configure the long DRX cycle for the user equipment to be a second cycle length for a service other than the voice service in case the user equipment is identified as not performing the voice service, wherein the first cycle length is shorter than the second cycle length;
and
send the first cycle length, the second cycle length, or an instruction for instructing the user equipment to deactivate DRX;
and
wherein the user equipment is configured to receive paging according to the first cycle length, the DRX deactivation instruction, or the second cycle length;
wherein the base station is configured to identify that the user equipment initiates the voice service based on:
detecting that there is a data packet transmitted on a signaling bearer of QCI=5;
detecting that a message sent on a signaling bearer of QCI=5 is a session initiation protocol (SIP) invite message;
detecting that a message sent on a signaling bearer of QCI=5 is an acknowledgement response message for an SIP invite message;
and/or
receiving a notification from a core network or an IP multimedia subsystem (IMS), wherein the notification indicates that the user equipment initiates the voice service.
