To facilitate the understanding of the present invention, a kind of applicable possible network architecture of the lower embodiment of the present invention is first introduced below Figure.Referring to Figure 1, architecture diagram shown in includes base station, UE.In the network architecture, paging be by base station triggers, it is optional , in this case, paging message is used to that system information to be notified to update, and notice UE receives tsunami warning system (EarthquakeandTsunamiWarningSystem, ETWS), commercial mobile phone early warning system Information such as (CommercialMobileAlertSystem, CMAS).The P- of the user equipment is carried in the paging message RNTI.Wherein, the base station can realize the function of paging UE in unlicensed band.In the specific implementation, generating UE in base station Paging message after, according to the configuration information of DRX, according to paging frame calculation formula and paging subframe calculation formula, calculating is sought Frame and paging subframe are exhaled, and access channel is attempted in base station on paging frame, if being successfully accessed, base station is sent in paging subframe Paging message carries the P-RNTI of UE in the paging message.

Fig. 2 is referred to, for the embodiment of the invention provides alternatively possible network structures, as shown in Fig. 2, architecture diagram Including base station, UE, mobility management entity (MME).In the network architecture, paging is triggered by MME.When network side has UE Related service when, the tracking area that MME was registered according to UE, the base station for being included to the tracking area by S1 interface sends paging Message carries the P-RNTI of UE in the paging message.After base station receives paging message, by determining the P-RNTI of UE, in turn Find tracing area mark (TrackingAreaIdentity, TAI) list of UE, and the cell in tracking zone list The paging information is directly passed through UE, specifically basis after communication connection is established in base station and UE by the paging eated dishes without rice or wine The configuration information of DRX calculates paging frame and paging subframe, and base according to paging frame calculation formula and paging subframe calculation formula It stands and attempts access channel on paging frame, if being successfully accessed, base station sends paging message in paging subframe.

Wherein, the calculation formula of paging frame and paging subframe is introduced referring to following:

The calculation formula of paging frame PF are as follows:

SFNmodT=(TdivN) * (UE_IDmodN) (1)

Wherein, the value of all System Frame Numbers (SystemFrameNumber, SFN) for meeting formula (1) is all PF. Since the value range of SFN is 0~1023, so PF can be in the appearance of 0~1023 value range periodically.

Calling time (PagingOccasion, PO) is that user equipment needs to monitor subframe numbers of the PDCCH on paging frame. After calculating PF, if call number i_s of the PO of UE on PF is calculated again, then further according to the mapping between i_s and PO Relationship, so that it may accurately obtain the accurate time location that UE should go the PDCCH monitored to occur.

It is directed toward the calculation formula of the call number (i_s) of calling time (PagingOccasion, PO) are as follows:

I_s=floor (UE_ID/N) modNs (2)

The calculation formula of the number N of PF in DRX cycle are as follows:

N=min { T, nB } (3)

The calculation formula of the number N s of PO in PF are as follows:

Ns=max { 1, nB/T } (4)

Wherein, the configuration information of DRX includes paging cycle T, paging density nB.Specifically, T is special according to cell where UE The fixed specific DRX cycle of DRX cycle and UE is come what is determined, and e.g., T=min { Tc, Tue }, Tc is the specific DRX of cell here, Value is 32,64,128,256, and unit is radio frames；Tue is the specific DRX of UE, value 32,64,128,256, and unit is Radio frames.Paging density nB value is 4T, 2T, T, T/2, T/4, T/8, T/16, T/32, which indicates described at least one Number is paged in paging cycle.

Further, N indicates the number of the paging frame in DRX cycle；Ns, which indicates to be used as in the paging frame of paging, pages son The number of frame.For example, a radio frames include 10 subframes, and in the case that the radio frames are used as paging, this is wireless Frame is referred to as paging frame, so that the paging frame includes 10 subframes, for example when nB=1/2T, Ns=1 illustrates that the paging frame has 1 A subframe is for paging；For another example, when nB=4T, Ns=4 illustrates that each radio frames have 4 subframes for paging.UE_ID= IMSImod1024.Wherein, IMSI is international mobile subscriber identity (InternationalMobileSubscriberIdentificationNumber), for UE described in unique identification, right After IMSI modulo operation, UE_ID can also be with the unique identification UE.

Further, in formula (1), after determining T, UE_ID, N, it is capable of determining that the corresponding SFN of PF.In LTE In system, the value range of System Frame Number is 0~1023；Determining SFN is calculated according to formula (1), so that it may which the SFN is corresponding Radio frames be determined as send UE paging message paging frame PF.Then, it is determined in paging frame for sending seeking for UE Exhale the paging subframe of message.According to the introduction of above-mentioned Ns, the subframe that there are at least one for paging in a paging frame.PO is used In the serial number of the paging subframe for the paging message for sending UE that instruction is determined in paging frame, specifically: in formula (2) In, after determining UE_ID, N, Ns, first determine i_s；Then further according to the mapping relations between i_s and PO, so that it may really Determine PO, and then determines the position for paging subframe in paging frame.

Please also refer to Fig. 3, for the embodiment of the invention provides a kind of exemplary diagrams of paging frame.As shown in figure 3, at one It include multiple radio frames in DRX cycle.By formula (1), formula (3) and after determining T, UE_ID, calculating is to SFN 20 radio frames are paging frame, and further, crossing in the paging frame includes multiple subframes, and corresponding subframe numbers are respectively #0, # 1,#2,#3,#4,#5,#6,#7,#8,#9；Pass through formula (2), formula (3), formula (4) and after determining T, UE_ID, knot The mapping relations between i_s and PO are closed, the subframe numbers that paging subframe is calculated are #5.The calculating of paging frame can be passed through in this way The calculation formula of formula and paging subframe determines the paging frame that paging message is sent in DRX cycle and paging subframe.

It should be noted that the mapping relations in the embodiment of the present invention between i_s and PO can refer to 3GPPTS36.304V14.2.0 specific introduction in, details are not described herein.

Equally, in the network architecture shown in fig. 1 or fig. 2, UE according to the configuration message of DRX, according to PF calculation formula and PO calculation formula, calculates separately PF and PO, such UE can PO occurs in PF time location monitored on PDCCH up and be The no P-RNTI for carrying UE.If carrying the P-RNTI of UE on PDCCH, just according to the ginseng of the PDSCH indicated on PDCCH Number goes to receive the data on PDSCH；If UE does not parse the P-RNTI of UE on PDCCH, no longer need to receive on PDSCH Data, so that it may enter suspend mode according to DRX cycle.

Based on this mechanism, in a DRX cycle, UE only can receive PDCCH in the time location that PO occurs up, Then it goes to receive PDSCH further according to needs.But due to base station it is possible that be not successfully accessed channel in unlicensed band, because This base station and not sent paging message.For UE, in a DRX cycle, UE cannot be listened at this time in corresponding PF The P-RNTI of itself is listened in PDCCH, UE, which can take for eNB, does not have downlink data to reach and be again introduced into DRX state, causes The paging time delay of the downlink unlicensed band of the UE increases, i.e., base station is once accessed unsuccessful, it is necessary to which UE is waited next time DRX reduces paging efficiency in this way.

And in embodiments of the present invention, base station is getting the paging message that the user equipment being paged is user equipment In the case of, first according to the configuration information of the target DRX of user equipment, determine at least two virtual paging frames；Then at least two Access channel is attempted on a virtual paging frame, determines that the virtual paging frame of one of them to arrive after it is successfully accessed channel is target Virtual paging frame, and sent a notification message to user equipment by destination virtual paging frame, Downlink Control Information and paging message. Base station can improve the probability that base station is successfully accessed channel, so that the user sets by repeatedly attempting access channel in this way The paging time delay of standby reception paging message reduces, and improves paging efficiency.It should be pointed out that optional, destination virtual Paging frame can be to be successfully accessed the virtual paging frame of channel earliest, here " be successfully accessed the virtual paging frame of channel earliest For destination virtual paging frame " it is not necessarily and is calculated since at the time of channel is accessed at first in base station, it can also be by base station and user Agreement is using the radio frames of the sometime start time after accessing channel as destination virtual paging frame.Here " agreement " It can be base station and send jointly to user in broadcast message and other broadcast messages；It is also possible to base station not prior notice user, User carries out blind Detecting acquisition when receiving paging message.

It should be noted that the base station in the embodiment of the present invention can apply in the paging scene of unlicensed band, by There is more resource in authorized spectrum band, in paging scene, base station is not necessarily to seize channel with the equipment of other systems, therefore, Base station in the embodiment of the present invention, which is realized, realizes the function of calling user device in unlicensed band.In addition, optional, the present invention Base station in embodiment can also be realized other than it may be implemented in the function that unlicensed band realizes calling user device The function of authorized spectrum band realization calling user device.

The scheme of the embodiment of the present invention can be applied in the wireless network architecture that there is paging scene, such as the whole world is mobile Communication system (GlobalSystemforMobileCommunication, GSM), Universal Mobile Communication System The wireless communication system of (UniversalMobileTelecommunicationsSystem, UMTS), future 5G or other are wireless Communication system etc..
