An embodiment of the present invention provides a kind of method of control UE (User Equipment, user equipment) monitoring carrier wave, As shown in Figure 1, including：

101, first base station sends the first instruction message to the UE, to indicate that the UE ceases listening for the first base station First carrier DSS (UE-specific Search Space, dedicated search space) all or part of DCI (Downlink Control Information, Downlink Control Information).

Wherein, first instruction message be used to indicate UE cease listening for first carrier dedicated search space DSS it is complete Portion or part Downlink Control Information DCI.

Specifically, when UE is moved to the range of the second base station covering, first base station determines UE without monitoring the complete of DSS Portion or when the DCI of part, the first instruction message is sent to UE.

Further, first identifier information is carried in the first instruction message.Wherein, the first identifier information is for marking The DCI for the DSS that the UE is ceased listening for is shown.

Optionally, the part DCI includes uplink DCI or downlink DCI, the first identifier information include：Uplink DCI's The information of information or downlink DCI.

Wherein, the uplink DCI refers to the DCI for distributing ascending resource.The downlink DCI refers to being used for allocation of downlink The DCI of resource.

Alternatively, the part DCI includes the DCI of at least one format, the first identifier information includes：At least one lattice The sequence number information of the DCI of formula.

It should be noted that the sequence number information of the DCI of at least one format refers at least one directional information The sequence number information of DCI.For example, the sequence number information of uplink DCI.

Further, the first instruction message can be the DCI message for the DSS for deactivating first carrier, can also be downlink BSR (Buffer State Report, buffer status report) message.Wherein, the downlink BSR message is waited for for recording first base station It sends, the corresponding data volume of the UE.

It should be noted that the first instruction message can also be that other message, the present invention are without limitation.

It should be noted that the first carrier of first base station can be the main carrier of UE.

102, the second base station sends control message with to described by the Data Radio Bearer DRB of the second carrier wave to the UE UE is controlled.

Specifically, after first base station sends the first instruction message to UE, first base station is not in the DSS by first carrier All or part of DCI to UE send control message.The control message that UE need to be sent to is sent to the second base station by first base station, Second base station by this control message by DRB (Data Radio Bearer, Data Radio Bearer) be sent to UE so as to UE into Row control.

It should be noted that it is described to UE carry out control may include：To the control that UE is measured, the control of switching, The control of cell reselection, the control and the control in terms of bearer management of each layer parameter configuration, can also be otherwise control System, the present invention are without limitation.

103, the first base station and the second base station provide service for the UE jointly.

Wherein, the service includes：Data service and signalling service.

Specifically, in the case where UE ceases listening for the part DCI of the DSS of the first carrier of first base station, in the first base It stands after sending control message to UE by the second base station, first base station can be UE offer data services with the second base station, and First base station provides signalling service for UE.

For example, first base station carries out the communication of downlink data with UE, the second base station carries out the communication of upstream data with UE.The The UE upstream datas sent can be forwarded to first base station by two base stations.

In the case where UE ceases listening for whole DCI of the DSS of the first carrier of first base station, pass through in first base station After two base stations send control message to UE, first base station provides signalling service for UE, and the second base station provides data service for UE.

An embodiment of the present invention provides a kind of method of control UE monitoring carrier waves, first base station sends the first instruction to UE and disappears Breath, to indicate that UE after receiving the first instruction message, ceases listening for all or part of the DSS of the first carrier of first base station DCI.At this point, the second base station sends control message to control UE by the DRB of the second carrier wave to UE, first base station and the Two base stations provide data service for UE jointly.In this way, UE monitors all or part of DCI of the DSS of first base station without the moment, the One base station can be sent control signaling by the DRB of the second carrier wave of the second base station to UE, to reduce the power consumption of UE, and be improved User experience.

An embodiment of the present invention provides a kind of methods of control user equipment (UE) monitoring carrier wave, as shown in Fig. 2, including：

201, the first instruction message that first base station is sent is received.

Further, the first instruction message carries first identifier information.Wherein, the first identifier information is for indicating Go out the DCI for the DSS that the UE is ceased listening for.

Specifically, in the case where UE is to be moved to the coverage area of the second base station, if first base station determines that UE is not necessarily to The part DCI of the DSS of the first carrier of first base station is monitored, then the first instruction that first identifier information is carried to UE transmissions disappears Breath, UE receives the first instruction message sent, and also carries first identifier information in the first instruction message received.In UE When being moved to the coverage area of the second base station, if first base station determines that UE is not necessarily to monitor the DSS of the first carrier of first base station Whole DCI, then to UE send the first instruction message, do not carry any identification information in the first instruction message at this time.

Further, the first instruction message can be the DCI message for the DSS for deactivating first carrier.First instruction message It can also be downlink BSR message.Wherein, first base station is to be sent, and the UE is corresponding for recording for the downlink BSR message Data volume.

202, according to first instruction message, all or part of DCI of the DSS is ceased listening for.

Specifically, in the case where the first instruction message is the DCI message for the DSS for deactivating first carrier, UE is received After first instruction message, first identifier information is carried in the first instruction message if detecting, is disappeared according to first instruction First identifier information in breath ceases listening for the part DCI of the DSS of the first identifier message identification.

Further, if first identifier information includes：When the information of uplink DCI, UE stops to the first carrier The associated up-link carriers of SIB2 (System Information Block 2, system information block 2) send upstream data.Namely It says, UE ceases listening for the uplink DCI of first carrier.If first identifier information includes：When the information of downlink DCI, then according to First identifier information cease listening for the first carrier with downlink DCI.

Also, UE is on first carrier using the first DRX (Discontinues Receive, discontinuous to receive) pattern ginseng Number is discontinuously to be received.The DRX mode parameter of first carrier is first by the second DRX mode Parameter Switch by as UE DRX mode parameter.

In traditional LTE (long term evolution of Long Term Evolution, 3GPP) system, DRX is when UE is in sky When not busy (IDLE) state, UE without RRC connections and the specific resource of user, therefore mainly listening broadcast message with seek The scheduling information of the public control message such as message is exhaled, therefore, as long as carrying out PDCCH for the UE configurations longer discontinuous reception period The blind Detecting of the DCI of (Physical Downlink Control Channel, Physical Downlink Control Channel) channel, so that it may with Achieve the purpose that discontinuous reception.The idle mode DRX parameters, refer to network be UE configuration when UE is in idle condition DRX parameters, generally comprise DRX cycle and for calculate UE monitor the moment some other parameters.

The DRX that also has state of activation corresponding with idle mode DRX, the DRX of so-called state of activation, which refer to that UE is in, to be swashed When (also referred to as RRC connection status) living, UE discontinuously carries out the monitoring of the DCI of PDCCH to obtain according to certain period Scheduling information, it is however generally that, the period of the DRX of state of activation is more shorter than the DRX cycle of idle mode, and UE is needed in each period The time for monitoring DCI is longer, so, using state of activation DRX than idle mode DRX more power savings.

In embodiments of the present invention, when UE is operated in first base station and the second base station, although UE is active, UE Still the monitoring for carrying out DCI using the DRX parameters of idle mode on first carrier, so that UE is on first carrier More power saving.For example, when ceasing listening for whole DCI of DSS of first carrier, UE can use the DRX of idle mode to join Number monitors the DCI of CSS, although in this way, UE is still maintained is connect with the RRC of first carrier, is still within state of activation, UE It can be reached than using DRX ginsengs when activation pattern (or referred to as connection status) by using the DRX parameters of idle mode The better power saving effect of number.

Wherein, the first DRX mode parameter can be the DRX parameters under idle mode.The idle mode DRX parameters Refer to when UE is at idle state (idle mode), network is the DRX parameters of UE configurations.

Second DRX mode parameter can be the DRX parameters under state of activation.DRX parameters under the state of activation refer to For UE at state of activation (active mode), network is the DRX parameters of UE configurations.

Optionally, UE stops to associated up-link carrier PUCCH (the Physical Uplink of the SIB2 of first carrier Control Channel, physical uplink control channel) and/or PUSCH (Physical Uplink Share Channel, Physical Uplink Shared Channel) on feedback CQI (Channel Quality Indicator, channel quality instruction), PMI, RI (RankIndication, order instruction), PTI (Precoding Type Indicator, precoding type instruction) etc. Information.

If the first identifier information includes：The sequence number information of the DCI of at least one format then refers to according to described first Show the first identifier information in message, ceases listening for the part DCI of the DSS of the first identifier message identification.Namely It says, at least one format of the DSS of first carrier is ceased listening for according to the sequence number information of the DCI of at least one format The DCI of the sequence number information mark of DCI.

If detecting without carrying first identifier information in first instruction message of reception, refer to according to described first Show message, ceases listening for whole DCI of the DSS of the first carrier.

Further, UE still keeps monitoring described in all or part of DCI for the DSS for ceasing listening for first carrier The DCI of the CSS (Common Search Space, public search space) of one carrier wave, so as to continue to obtain first base station Common control information keeps the connection between first base station.

It should be noted that UE can obtain the scheduling information of public control message by monitoring the DCI of CSS, for example, System information.UE can obtain professional message and business datum by monitoring the DCI of DSS.First base station is needed through CSS's Public control message is sent to all UE of first base station service by DCI, at this point, first base station only need to be wide by the DCI of CSS Public control message is broadcast, all UE of first base station service can receive public control message, and first base station can at this time Only to send primary public control message.

If UE ceases listening for the DCI of the CSS of the first carrier of first base station, first base station need to be by public control message It is sent one time for each UE of its each service, will produce the wasting of resources in this way, and increase the workload of first base station, institute With UE need to keep monitoring the DCI of the CSS of the first carrier of first base station.

Optionally, the time for monitoring CSS can be determined according to the DRX parameters of the first DRX mode parameter.

In the case where the first instruction message is downlink BSR message, UE receives the downlink BSR message of first base station transmission Afterwards, downlink BSR message can be detected, if detecting, the data volume recorded in downlink BSR message is not more than the first threshold value, UE ceases listening for whole DCI or whole downlink DCI of the DSS of first carrier, and keeps monitoring the DCI of the CSS of first carrier.If It detects that the data volume recorded in downlink BSR message is more than the first threshold value, but is not more than the second threshold value, then UE is ceased listening for The part DCI or part downlink DCI of the DSS of first carrier, and keep monitoring the DCI of the CSS of first carrier.If detecting downlink The data volume recorded in BSR message is more than the second threshold value, then UE keeps monitoring whole DCI of the DSS of first carrier, and monitors The DCI of the CSS of first carrier.

Alternatively, UE can also determine whether to monitor the DCI of first carrier according to the uplink BSR of itself, if detecting uplink The data volume of BSR is not more than third threshold value, then UE ceases listening for whole DCI or whole uplink DCI of the DSS of first carrier, And keep monitoring the DCI of the CSS of first carrier.If detecting, the data volume recorded in uplink BSR message is more than third threshold value, And being not more than the 4th threshold value, then UE ceases listening for the part DCI or part uplink DCI of the DSS of first carrier, and keeps monitoring The DCI of the CSS of first carrier.If detecting, the data volume recorded in uplink BSR message is more than the 4th threshold value, and UE keeps prison Whole DCI of the DSS of first carrier are listened, and monitor the DCI of the CSS of first carrier.

Alternatively, after UE receives the downlink BSR message of first base station hair, downlink BSR message and UE itself can be detected Uplink BSR message, if detecting the data volume recorded in downlink BSR and uplink BSR message no more than the 5th threshold value, UE Whole DCI of the DSS of first carrier are ceased listening for, and keep monitoring the DCI of the CSS of first carrier.If detect downlink BSR and The data volume recorded in uplink BSR message is all higher than the 5th threshold value, and no more than the 6th threshold value, then UE ceases listening for The part DCI of the DSS of one carrier wave, and keep monitoring the DCI of the CSS of first carrier.Otherwise, UE keeps monitoring first carrier Whole DCI of DSS, and monitor the DCI of the CSS of first carrier.

It should be noted that the first threshold value, the second threshold value, third threshold value, the 4th threshold value, the 5th threshold value, 6th threshold value is all pre-set.

Alternatively, when UE receives the downlink BSR that first base station issues and is higher than seven thresholdings, determine to first carrier The DCI of the DCI and DS S of CSS is monitored.Otherwise the DCI of the CSS of first carrier is listened only to.

Alternatively, when the uplink BSR of UE oneself is higher than eight thresholdings, determine to the DCI and DSS of the CSS of first carrier DCI is monitored.Otherwise the CSS of first carrier is listened only to, and is not listening to the DCI of DSS.

Alternatively, when UE determines downlink BSR and uplink BSR is above nine thresholdings, determine to the CSS's of first carrier The DCI of DCI and DSS is monitored, and the CSS of first carrier is otherwise listened only to, and is not listening to the DCI of DSS.

It should be noted that the 7th threshold value, the 8th threshold value, the 9th threshold value are all pre-set.

203, by the Data Radio Bearer DRB of the second carrier wave receive that the second base station sends for being controlled UE Control message.

Specifically, after UE ceases listening for all or part of DCI of the DSS of the first carrier of first base station, monitors second and carry All or part of DCI of the DSS of wave receives the use that the second base station is sent using the Data Radio Bearer DRB of second carrier wave In the control message controlled UE.
