When step S101 is performed, generally according to LTE-U base stations spatial relation, by LTE-U base stations successively since 0
Numbering, the numbering of adjoining LTE-U base stations is continuous, is then grouped the LTE-U base stations after numbering, wherein, belong to
The LTE-U base station coverage areas of same packet are continuous, and the LTE-U base station coverage areas of different grouping are different.Assuming that such as Fig. 3 institutes
Show, the LTE-U base stations in setting regions are divided into three set as shown in Figure 3, and each set is more comprising what is be positioned proximate to
Individual LTE-U base stations, so, unlicensed spectrum resource just periodically can be allocated to the different time periods by network side equipment
Corresponding set, such as, a cycle T is divided into 3 time periods T1, T2, T3, wherein in time period T1, set 1
LTE-U base stations can use unlicensed spectrum resource, and the LTE-U base stations in time period T2, set 2 can use unauthorized frequency
Spectrum resource, the LTE-U base stations in time period T3, set 3 can use unlicensed spectrum resource, it is seen then that the LTE- in set 1
U base stations can only take LTE-U unlicensed spectrum resources in time period T1, and within the T1 time periods, LTE base station completes control signaling
Transmission after, all available running time-frequency resource carries out data transmission for unconditional seizure；Because LTE-U base stations are to LTE system service
In the range of system in the frequency range have strong jamming, each Wi-Fi systems are based on CSMA/CA mechanism, are infinitely kept out of the way, until
LTE system does not work, and outside the T1 time periods, each Wi-Fi base stations in set 1 can just use according to 802.11 regulation
The running time-frequency resource of CSMA/CA mechanism shared channels.
Wherein, it is described to determine that each is integrated into same period T the different time period for taking unlicensed spectrum resource, bag
Include：
N number of set is started from scratch and is numbered, obtain the set identification of each set, calculated in the cycle according to formula one
Each set starts to take the initial time of unlicensed spectrum resource in T；
Ton_i=floor (T/N) × i ... ... ... ... ... formula [1]
Wherein, floor is represented and rounded downwards, and N is set sum, and i is numbering, and T is time cycle, Ton_iIt is set identification
For the set of i takes the initial time of unlicensed spectrum resource.
Therefore, start to take the initial time of unlicensed spectrum resource according to each set and default each set takes
The time span of unauthorized frequency range frequency spectrum resource, determines that each is integrated into same period T and takes unlicensed spectrum resource not
The same time period.
As shown in figure 4, the unlicensed spectrum resource occupation duration of the LTE-U base stations of each set, is designated as Ton；Collection
The LTE-U base stations in 1 are closed from Ton_1Start to take unlicensed spectrum resource, occupy TonStop taking afterwards, then, set 2
In LTE-U base stations from Ton_2Start to take unlicensed spectrum resource, occupy TonStop taking afterwards, until in set n
LTE-U base stations are from Ton_nStart to take unlicensed spectrum resource, occupy TonStop taking afterwards.The unauthorized frequency of the base station
Section carrier occupancy duration Ton, value is not more than cycle T.As seen from Figure 4, the LTE-U base stations of identity set are belonged to, its is non-to award
Power frequency range carrier wave open at the beginning of between it is identical, the unlicensed spectrum resource of different sets starts to take the initial time of resource not
Together, any time in cycle T always have LTE-U base stations take unlicensed spectrum resource.So that in cycle T, when any
Carve, the unauthorized frequency range carrier wave for always having base station is opened, and LTE system resource can be fully utilized always, while wherein working as portion
When dividing set to be not take up unlicensed spectrum resource, the Wi-Fi base stations around the set can just take unlicensed spectrum resource, real
The fair of shared channel uses between existing LTE-U and Wi-Fi systems, while, it is ensured that LTE-U networks can be always in unauthorized frequency range
It is lasting that service is provided.

Technology is mainly, and the whole network is using all LTE-U base stations in identical unlatching/shut-in time, i.e. setting regions in setting time
Unlicensed spectrum resources are all taken in section, after occupying setting time section, and in follow-up setting time section all
Stop taking unlicensed spectrum resource.When LTE-U systems stop taking unlicensed spectrum resource, LTE-U systems are unauthorized
The service disruption that frequency range is provided, produces influence will certainly to the LTE terminal for accessing unauthorized frequency range carrier wave, can even be led when serious
LTE terminal call drop is caused, Consumer's Experience is reduced, the overall performance of network is also affected.If each base station be voluntarily determined and
Adjustment unlicensed spectrum resource occupation time, it is contemplated that the LTE-U base stations of a certain Wi-Fi base stations of influence there may be multiple, if
The unauthorized frequency range carrier occupancy Time Inconsistency of these base stations, can have a strong impact on the transmission of Wi-Fi systems.And the present invention is implemented
Example is divided into different set by by the LTE-U base stations in setting regions, and unlicensed spectrum resource is taken in subregional, so that it may
Unlicensed spectrum resource only can be taken in the same time period with the LTE-U base stations for ensureing a certain Wi-Fi base stations of influence, in the time
Would not be taken again outside section, so Wi-Fi base stations can just access unlicensed spectrum resource outside the time period.So,
Ensure that LTE-U provides continuous service in unauthorized frequency range, and LTE-U can be met and passed with the data of Wi-Fi both sides
Defeated time demand.

Unanimously.
Data flow based on bag is typically paroxysmal, has data transfer within a period of time, but at ensuing one section
There is no data transfer in long period.When there is no data transfer, can be by stopping receiving PDCCH (Physical
Downlink Control Channel, Physical Downlink Control Channel) (can now stop PDCCH blind checks) reduce power consumption, from
And lift service time of battery.Here it is the origin of DRX.The fundamental mechanism of DRX is for the UE in RRC_CONNECTED states matches somebody with somebody
Put a DRX cycle.DRX cycle is by " On Duration (activation phase) " and " Opportunity for DRX (rest period) " group
Into：At " On Duration " in the time, UE is monitored and is received PDCCH；At " Opportunity for DRX ", in the time, UE is not
PDCCH is received to reduce power consumption.Have in These characteristics, therefore gathering network overlay area in data receiver in view of terminal
