The present invention relates to the field of communications technologies, and in particular, to a method and an apparatus for discontinuously monitoring a control channel in a trunking communication system.
Background
The broadband digital trunking communication system based on the time division-long term evolution (TD-L TE) technology can not only support various multimedia services of the TD-L TE mobile communication system, but also provide basic trunking call services and trunking multimedia services.
The cluster group calling service is a typical service in a cluster system, is participated by a plurality of users together, and plays a great role in the field of private network communication. In order to realize fast call establishment of the cluster group call service, for the characteristics of the point-to-multipoint service, the downlink generally adopts a broadcast mode to send control plane signaling and user plane data, and the group call user in an idle state can directly receive the control plane signaling and the user plane data without being converted into a connection state, thereby accelerating call establishment and service data reception.
In L TE system, in order to save power of User Equipment (UE) and increase the usage time of UE battery, Discontinuous Reception (DRX) mechanism is introduced, i.e. when UE is in connection state, it is not necessary to monitor the control channel of base station (eNode B) continuously, but to monitor the control channel discontinuously.
In order to implement DRX operation specifically, multiple timers are defined in the TS36.321 protocol, and a working mode combining the timers and DRX is adopted, so that the eNode B maintains the same DRX working mode as the UE, and knows in real time whether the UE is in an active period or a sleep period, thereby ensuring that data transmission is performed only in the active period of the UE.
In a trunked communication system, a trunked UE may listen to a group call in a Radio Resource Control (RRC) idle state. If the cluster UE continuously monitors the control channel of the eNodeB all the time in the whole group call process, it is very power consuming.

Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more clearly apparent, the technical solutions of the present invention are described in detail below with reference to the accompanying drawings and examples.
The embodiment of the application provides a method for discontinuously monitoring a control channel in a trunking communication system, which is applied to UE in a trunking group in the process of group call service. And by configuring the cluster DRX function for the cluster group, the UE in the cluster group determines the activation time according to the cluster DRX configuration information configured by the base station, and monitors the PDCCH within the activation time. Therefore, when the cluster UE listens to the group call, the cluster UE does not need to continuously monitor the PDCCH all the time, and power can be saved.
For convenience of description, the UEs in the cluster group are referred to as cluster UEs hereinafter.
The group calling service process comprises the following steps: the method comprises the steps of group calling establishment process, receiving of group calling service established by group calling, speaking right application of UE receiving group calling, receiving mobility of group calling UE, receiving group calling service of other groups changed by group calling UE and the like.
In the group calling establishing process, a core network initiates the establishment of group downlink bearing to related base stations, each base station configures G-RNTI and/or SPS G-RNTI for a group, cluster UE configures G-RNTI and/or SPS G-RNTI configured by a serving cell for the cluster group, and when the cluster UE performs cell switching or cell reselection, the G-RNTI and/or SPS G-RNTI configured by a target cell for the cluster group is reconfigured.
In the technical solution provided in this embodiment, for the cluster UE configured with the cluster DRX function, if the cluster UE is not configured with the cluster DRX function, the monitoring mode of the cluster UE not configured with the cluster DRX function is not described in detail according to the existing implementation.
In this embodiment, a base station configures cluster DRX configuration information for a cluster to implement a cluster right DRX function configured for the cluster, where the cluster DRX configuration information includes: cluster DRX cycle, cluster DRX cycle start time offset, and cluster group duration timer.
And the base station carries the cluster DRX configuration information in an RRC command and sends the RRC command to the cluster UE.
When the cluster DRX configuration information is carried in the RRC command, the cluster DRX configuration information is carried by adding a cluster DRX configuration (trunk DRX-Config) cell in the RRC command.
Specifically, the TrunkingDRX-Config cell may be added in a cluster group call configuration (GroupCallConfig) cell; may also be added in a trunking paging message (TrunkingPaging) cell.
For ease of understanding, two cluster DRX configuration cell structures are given below, but not limited to these two structures:
the first structure is as follows:
the above is a description of a first cell configuration structure for trunking DRX, in which an uplink group duration timer (ontrunked group scheduling timer) indicates an activation timing of trunking DRX, a length of the timer determines a time for which UEs in a trunking group periodically monitor a control channel, and a value of the uplink group duration timer may be represented by a number of PDCCH subframes. The value psf1 corresponds to 1 PDCCH subframe, psf2 corresponds to 2 PDCCH subframes, and so on.
the trunkingDRX-Cycle represents a cluster DRX Cycle, the value of which may be expressed in number of subframes. The value sf2 corresponds to 2 subframes, sf5 corresponds to 5 subframes, and so on.
trunkingdrxStartOffset indicates the cluster DRX cycle start time offset. The value of the cluster DRX cycle start time offset is expressed in number of subframes.
The second structure is as follows:
the above is a description of a second cell configuration structure for trunking DRX, in which an uplink group duration timer (ontrunked group scheduling timer) indicates an activation timing of trunking DRX, a length of the timer determines a time period for which UEs in a trunking group periodically monitor a control channel, and a value of the uplink group duration timer may be represented by a number of PDCCH subframes. The value psf1 corresponds to 1 PDCCH subframe, psf2 corresponds to 2 PDCCH subframes, and so on.
the trunkingDRX-Cycle represents a cluster DRX Cycle, the value of which may be expressed in number of subframes. The value sf2 corresponds to 2 subframes, sf5 corresponds to 5 subframes, and so on.
trunkingdrxStartOffset indicates the cluster DRX cycle start time offset. The value of the cluster DRX cycle start time offset is expressed in number of subframes.
And when the cluster UE receives an RRC instruction sent by the base station, the cluster UE acquires cluster DRX configuration information configured for the cluster group by the base station in the RRC instruction and stores the cluster DRX configuration information locally so as to monitor a control channel. The trunking DRX configuration information is carried in a trunking DRX configuration cell newly added in the RRC command.
The following describes in detail a process of non-continuously listening to a control channel in a trunking communication system in an embodiment of the present application with reference to the accompanying drawings.
Referring to fig. 1, fig. 1 is a schematic flowchart illustrating discontinuous listening to a control channel in a trunking communication system according to an embodiment of the present application. The method comprises the following specific steps:
In this step, the time of starting the cluster group duration timer (onTrunkingGroupDurationTimer) each time is the subframe start time satisfying the following formula:
(SFN×10)+subframe number]modulo(trunkingDRX-Cycle)＝trunkingdrxStartOffset。
wherein, the trunk drx Cycle and the trunk drx startoffset are configured by the eNode B and sent to the clustered UE.
And the cluster UE determines the starting time of the cluster group duration timer according to the cluster DRX cycle and the offset of the starting time of the cluster DRX cycle. Cluster UE starts a cluster group duration timer from a subframe meeting the formula; the time of the timer in the running state after being started is the timing duration configured by the cluster group duration timer. In the embodiment of the present application, for a cluster UE configured with a cluster DRX function, when a cluster group duration timer corresponding to the cluster UE is in an operating state, the cluster UE determines that the cluster UE is currently within an active time.
Considering that L TE DRX is compatible, for a clustered UE, under certain conditions, such as different states of the clustered UE and whether L TE DRX is configured, the embodiments of the present application provide processing schemes for different conditions, which are specifically as follows:
in the first case: the cluster UE is configured with a cluster DRX function and monitors the PDCCH in the activation time when the cluster UE is in an RRC idle state.
When the cluster UE is in the RRC idle state, the L TE DRX is not configured, so the activation time only includes the time when the cluster group duration timer is in the running state.
In the second case, clustered UEs are configured with clustered DRX functionality and in RRC connected state, in which case there are L TE DRX configured and L TE DRX unconfigured.
When the L TE DRX is not configured, the PDCCH is continuously monitored, namely, the PDCCH is monitored in the inactive time and the active time.
And when L TE DRX is configured, monitoring the PDCCH in an active state, wherein the active time at the moment is any one of the following occurrence time, namely determining that the PDCCH is currently in the active time as long as any one of the following occurrence time:
a time that the cluster group duration timer is in the run state;
the time when the duration timer (onDurationTimer) is in the running state;
drx-the time that the inactivity timer (drx-inactivity timer) is running;
drx-the time that the retransmission timer (drx-retransmission timer) is in a running state;
a time when the MAC contention resolution timer (MAC-ContentionResolutionTimer) is in a running state;
there is a pending scheduling request sent on PUCCH;
the authorization of uplink HARQ retransmission arrives, and data exists in a corresponding HARQ buffer;
after successful reception of the random access response for the non-UE selected preamble, the PDCCH indicating new data transmission identified with the C-RNTI has not been received.
In the above case, the cluster group duration timer is a timer generated by configuring the cluster DRX function, and the duration timer, the DRX-inactivity timer, the DRX-retransmission timer, and the MAC contention resolution timer are timers generated by configuring L TE DRX.
In each of the above cases, the cluster UE monitors the PDCCH when determining that the subframe is part of the measurement interval and determining that the current cluster group duration timer is in the running state for any PDCCH subframe during the activation time; when it is determined that the subframe is part of a measurement interval and it is determined that the current cluster group duration timer is not in an active state, the PDCCH is not monitored.
Considering the point-to-multipoint characteristic of the cluster group call, when the UE measurement conflicts with the time of group call reception, the group call is preferentially received.
When it is determined that the subframe is not part of a measurement interval, performing the following:
monitoring a PDCCH; if the PDCCH scrambled by the C-RNTI or the T-C RNTI indicates downlink transmission or the subframe is configured with downlink authorization, starting an HARQ RTT timer for the corresponding HARQ process and stopping a drx-retransmission timer of the corresponding HARQ process; and if the PDCCH scrambled by the C-RNTI or the T-C RNTI indicates a new transmission, starting or restarting a drx-retransmission timer.
In the specific embodiment of the present application, there are some special cases, in which the PDCCH is continuously monitored. These special cases are specifically as follows:
switching RRC connected UE which has received the group call, and if the cluster UE does not receive cluster DRX configuration information corresponding to the cluster group call in a target cell;
reselecting the ID L E state UE cell which has received the group call, and if the cluster UE does not receive the cluster DRX configuration information corresponding to the cluster group call in the target cell;
and G-RNTI is changed, and if the cluster UE does not receive cluster DRX configuration information corresponding to the cluster group calling.
Regardless of whether the PDCCH is being monitored or not, the cluster UE will normally transmit/receive HARQ feedback, if desired, and transmit a type-1 trigger type SRS.
In the inactive time, the cluster UE should not report the SRS of type-0 trigger type. If the high layer configures CQImasking (i.e. CQI-mask), when the onDurationTimer timer is not running, the CQI/PMI/RI/PTI should not be reported on the PUCCH; if the high layer does not configure CQI masking, in the inactive time, CQI/PMI/RI/PTI should not be reported on PUCCH.
After receiving new data transmission (uplink/downlink) indicated by the PDCCH scrambled by the C-RNTI or the T-C RNTI in the last subframe of the activation time, the UE can choose not to report the SRS/PMI/RI/PTI and/or transmission type-0 triggering type SRS on the PUCCH in at most 4 subframes. But this alternative does not apply to the onDurationTimer run phase.
It should be noted that, when the UE needs to read the system information of the BCCH, the paging message of the PCCH, and the trunking paging message of the TPCCH, the UE is not affected by the trunking DRX, and the UE can monitor the PDCCH scrambled by the corresponding RNTI (SI-RNTI/P-RNTI/TP-RNTI) at the corresponding time based on the configuration information provided by the RRC.
It should be noted that, when the trunking DRX is configured for the trunking group in the trunking group call setup process, the base station needs to maintain the same DRX operation mode as the trunking group and know whether the trunking group is in the active period in real time.
The base station schedules the cluster group to allocate resources in the activation period of the cluster group; and the UE in the cluster group can blindly detect the PDCCH in each downlink subframe in the activation period of the cluster group to receive the group call service.
Furthermore, in a group call session, the RRC states of the member UEs in the group are different, some UEs may be in an RRC idle state, some UEs may be in an RRC connected state, and even some UEs may change their RRC states during the group call session. However, for all UEs in the set group, the PDCCH must be monitored during the active period of the set group. During the non-trunking period of the trunking group, the UEs in the RRC connected state in the trunking group may also monitor the PDCCH at some time according to the above description.
Based on the same inventive concept, the application also provides a device for discontinuously monitoring the control channel in the trunking communication system, which is applied to trunking User Equipment (UE) in a trunking group in the process of group call service, and configures a trunking DRX function for the trunking group.
