Embodiment Construction

[0020] In order to make the object, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be described in detail below with reference to the accompanying drawings and examples.

[0021] An embodiment of the present application provides a method for discontinuously monitoring a control channel in a trunking communication system, which is applied to a UE in a trunking group during a group call service. By configuring the cluster DRX function for the cluster group, the UEs in the cluster group determine the activation time according to the cluster DRX configuration information configured by the base station, and monitor the PDCCH within the activation time. In this way, the trunking UE does not need to continuously monitor the PDCCH channel when answering the group call, which can save power.

[0022] Hereinafter, for the convenience of description, the UEs in the cluster group are referred to as cluster UEs.

Abstract

The invention provides a method and device for the non-continuous monitoring of a control channel in a cluster communication system, and the system comprises the steps that cluster UE obtains cluster DRX configuration information which is configured by a base station for a cluster group, wherein the cluster DRX configuration information comprises a cluster DRX period, the start moment offset of the cluster DRX period, and a cluster group time duration timer; the cluster UE determines the start time of the cluster group time duration timer according to the cluster DRX period and the start moment offset of the cluster DRX period; the cluster UE monitors a PDCCH (physical downlink control channel) in an activation time period, wherein the activation time period is a period when the cluster group time duration timer is in operation. Based on the same invention thought, the invention also proposes a device for non-continuous monitoring of the control channel in the cluster communication system. When the cluster UE receives a group call, there is no need to monitor the PDCCH continuously, thereby saving the power.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a method and device for discontinuously monitoring a control channel in a cluster communication system. Background technique [0002] The broadband digital trunking communication system based on Time Division-Long Term Evolution (TD-LTE) technology can not only support various multimedia services of the TD-LTE mobile communication system itself, but also provide basic trunking call services and trunking multimedia services. [0003] The trunking group call service is a typical service in the trunking system, which is participated by multiple users and plays a huge role in the private network communication field. In order to realize fast call establishment of the trunking group call service, according to the characteristics of the point-to-multipoint service, the downlink generally adopts the broadcast mode to send the control plane signaling and user plane data, and the gr...
