Above method monitors the business load change in macro base station coverage by obtaining the business load in macro base station coverage, when the business load, which changes, causes the business load occupancy in macro base station coverage to be less than or equal to the first thresholding, if there is activated state capacity in macro base station coverage shares base station, and the activated state capacity shares the service switching of base station to after macro base station, the business load of macro base station is without departing from load-threshold, just share base station to the activated state capacity and send SLEEP instruction, base station, which is shared, to trigger activated state capacity enters sleep state, reduce energy resource consumption；When the business load, which changes, causes the business load occupancy in macro base station coverage to be more than or equal to the second thresholding; if there is sleep state capacity in macro base station coverage shares base station; just the sleep state capacity into macro base station coverage shares base station transmission activation instruction; base station is shared with activated sleep state capacity; share the business load of macro base station, it is ensured that Consumer's Experience.It can be seen that; this method can adaptively in macro base station coverage network load change; sleep state capacity in activation macro base station coverage, which shares base station or the sleep state capacity in coverage is shared base station, enters sleep state, so as to carry out the administration of energy conservation of intelligence to wireless network on the whole.
In above step S310, the business load in macro base station coverage can be that the capacity in activated state is shared their business load of the cell periodic report of base station and obtained in cell and macro base station coverage by macro base station.Can also answer the call instruction of macro base station or network management device and report, and this call instruction can be issued with the cycle, it can also be issued according to the issuing the time of advance planning, for example in office building region, obvious change occurs in commuter time section in business load, call instruction can be then issued within early, middle and late three periods, is obtained in macro base station coverage
Business load.The present embodiment does not do any limitation.
It should be noted that above business load can be radio bearer（Radio Bearer, RB) utilization rate, number of users（The number of users refers to the active user number that network element is serviced）, or both overall balance.Certainly, it is only for example herein, the present embodiment can also can react the statistic of business load situation, such as the CPU occupation rates of accounting base-station using other.
Business load in macro base station coverage refers to that the business load occupancy in the business load that all cells that all base stations in activated state are covered in macro base station coverage are reported, macro base station coverage refers to the ratio for the full business load that the business load in macro base station coverage is accounted in macro base station coverage.By taking RB utilization rates and number of users as an example, the computational methods of business load occupancy in macro base station coverage are described in detail, now, the business load occupancy in macro base station coverage is the average RB utilization rates and average user number occupation rate in macro base station coverage.
It should be noted that; business load in macro base station coverage includes macro base station and activated state capacity shares base station; if being additionally provided with the other types of access network equipments such as the blind base station of benefit in macro base station coverage; then and these equipment be in activated state, then the business load in macro base station coverage also include the business load of these equipment.
Assuming that macro base station covers m cell, the full RB numbers that each cell is supported are MRB, full number of users is MUSR.There is N number of capacity to share base station in the macro base station coverage, the broadband that all capacity share base station cell is consistent with number of users specification；Each capacity, which shares base station, n cell, and the full RB numbers that each cell is supported are SRB, full number of users be SUSR, wherein, m, n and N are positive integer.Certain moment, the RB utilization rates that i-th of cell of macro base station is reported are that ^1^1^16 [1], number of users occupation rate are MUSRRate[i];And it is S that the activated state capacity in macro base station coverage, which shares the RB utilization rates that j-th of cell of base station report,RBRate j], number of users occupation rate be SUSRRate [j], the then average RB utilization rates AREA_RB in macro base station coverageUsed_ Rate and average user number occupation rate AREA_UserUsed_ Rate calculation formula are as follows：
ΑδΕΑ^Β ;ϊ6.≤ ¾ίδ = (∑^sMgg * ¾Rga3te?| ¾s * ¾sTe Warfare》/ (M^e ÷ N * a S^s) (1) flat H=(∑i¾ ¾ssRateii】 ÷∑^S^ S^ ^ )/Cm , :¾ ÷ :, ^ S, ^ (2) are in above step S320, the determination of the business load occupancy in macro base station coverage, this
Field computing staff is referred to above computational methods, will not be described in detail herein.
In above step S330 and S340; first thresholding and the second thresholding are two values of the ratio for the full business load that the business load in macro base station coverage is accounted in macro base station coverage respectively; the corresponding value of first thresholding characterizes a critical point; when the ratio for the full business load that the business load in macro base station coverage is accounted in macro base station coverage is less than this critical point, at least one activated state capacity in macro base station coverage can be made to share base station and enter sleep state.And first thresholding can set based on experience value, can also be determined according to operator for the demand of service quality, for example, can be arranged on less than 50%.The corresponding value of second thresholding characterizes another critical point; when the ratio for the full business load that the business load in macro base station coverage is accounted in macro base station coverage is higher than this critical point; at least one the sleep state capacity activated in macro base station coverage is needed to share base station, to share the business load of macro base station.It can be seen that, the first thresholding can be less than or equal to the second thresholding.Load-threshold can be set according to macro base station maximum traffic load capacity, or, load-threshold can be set to by certain proportion according to the QoS requirement of operator（Such as 60% ~ macro base station maximum traffic load capacity 80%), the not any limitation of # texts of this example.
In above step S330, when the business load occupancy determined in step S320 is less than or equal to the first thresholding, the activated state capacity that directly load-threshold can be less than or equal to business load and macro base station business load sum shares base station and sends SLEEP instruction, can continue to monitor macro base station coverage in business load for a period of time after, when business load occupancy in the macro base station coverage is still less than or equal to the first thresholding, the activated state capacity for being less than or equal to load-threshold to business load and macro base station business load sum again shares base station and sends SLEEP instruction, now, above step S330 further comprises step as shown in Figure 5：
S331 :If the business load occupancy determined in step S320 is less than or equal to the first thresholding; the capacity shares base station and is in activated state; and the capacity shares the business load of base station and the macro base station business load sum is less than or equal to load-threshold, obtains the business load in the macro base station coverage of preset times.Wherein, for the selection of preset times, the present embodiment does not do any limitation, specifically can change the more obvious time according to the business load of macro base station coverage in daily statistics
Length determines the number of preset times, naturally it is also possible to set according to the demand of operator.
For ease of statement, the preset times business load obtained in step S331 can uniformly be designated as the second business load, to be made a distinction with the first business load obtained in above-mentioned steps S310.It should be noted that, the preset times business load obtained in step S331 is uniformly designated as the second business load, it is identical to be not intended that the business load obtained every time, in second business load of preset times, the business load obtained every time can be with identical, can also be different, depending on the actual traffic load situation in macro base station coverage.
S332:According to the business load in the macro base station coverage of the preset times obtained in step S331, the business load occupancy in the macro base station coverage of preset times is determined.
S333:If the business load occupancy determined in step S332 is respectively less than or equal to the first thresholding, shares base station to the capacity and send SLEEP instruction.
So; through monitoring after a while; business load reduction interim in macro base station coverage can be avoided; in the case of returning to higher business load again quickly; base station is shared to activated state capacity and sends SLEEP instruction; activated state capacity is shared base station and entered after sleep state, and macro base station business load is higher, in addition it is also necessary to reactivates sleep state capacity and shares repeating for base station.
In the preferred embodiment, two business load report cycle period 1 Tlong and second round Tshort of cell configuration of base station can be shared for macro base station and activated state capacity.Wherein period 1 Tlong is more than second round Tshort.In daily monitoring, macro base station and activated state capacity are shared to business load report cycle configuration period 1 Tlong of the cell of base station.That is in above step S310, the business load in macro base station coverage is obtained using period 1 Tlong.When finding that business load occupancy is less than or equal to the first thresholding; the business load report cycle that macro base station and activated state capacity are shared to the cell of base station is adjusted to second round Tshort; to utilize the business load of macro base station described in shorter cycle monitoring; i.e. in above step S331, the business load in the macro base station coverage of preset times is obtained using second round.Shorten business load report cycle to be advantageous in that; if there is the trend of rapid decrease in the business load in macro base station coverage; shorten business load report cycle, be adapted to this trend, to reach that activated state capacity is shared base station during the reduction of business load amount enters
The effect of sleep state.For example; in office building region; obvious reduction trend occurs in quitting time section in business load amount, and peak occurs within an of short duration time in this trend, has crossed after this peak; business load amount can be significantly reduced; therefore, shorten business load report cycle, be beneficial to adapt to business load reduction trend; enter sleep state so as to quickly make activated state capacity share base station, reach the effect of fast energy-saving.
In addition, the capacity of possible more than one activated state shares base station in macro base station coverage.And the trend of business load amount reduction is there may be in macro base station coverage; so gradually decreasing with business load amount; the activated state capacity that can be saved shares the possible more than one in base station; even as business load amount is reduced in the case that only macro base station just can be supported, the capacity of all activated state can be made to share base station and enter sleep state.In this case, it disposably can share base station to the capacity of all activated state and send SLEEP instruction, can also send one by one.Specific strategy can include but is not limited to：When the business load sum of business load and macro base station that all activated state capacity shares base station is less than or equal to load-threshold, while sharing base station to all activated state capacity sends SLEEP instruction.Or; by the order of business load from high to low; an activated state capacity is excluded successively shares base station; calculate the business load sum that remaining activated state capacity shares base station and macro base station; and when calculating obtained business load sum less than or equal to load-threshold, share base station to all activated state capacity corresponding to now business load sum and send SLEEP instruction.Or, the business load of base station is shared according to activated state capacity, SLEEP instruction is sent according to order from small to large.
Preferably, the business load of base station can be shared according to activated state capacity, SLEEP instruction is sent according to order from small to large.This algorithm cylinder is single, and overhead is relatively small, and is more suitable for the characteristics of load of network changes randomness.Now, the communication means that the embodiment of the present invention is provided can include step as shown in Figure 6：
S610:The capacity that multiple activated states are provided with business load in acquisition macro base station coverage, macro base station coverage shares base station.
S620:According to the business load in the macro base station coverage obtained in step S610, the business load occupancy in macro base station coverage is determined.
S630:Whether the business load occupancy determined in judgment step S620 is less than or equal to the first thresholding, if performing step S640, otherwise terminates.
S640:If the business load occupancy determined in step S630 is less than or equal to the first thresholding, judge whether the business load sum of business load and macro base station that the minimum activated state capacity of current business load shares base station in macro base station coverage is less than or equal to load-threshold；If so, step 651 can be performed to 654, base station transmission SLEEP instruction can also be shared by the minimum activated state capacity of current business load directly into macro base station coverage, otherwise terminated.
S651 :Obtain the business load in the macro base station coverage of preset times.
S652:According to the business load in the macro base station coverage of the preset times obtained in step S651, the business load occupancy in the macro base station coverage of preset times is determined.
S653:Whether the business load occupancy determined in judgment step S652 is respectively less than or equal to the first thresholding, if performing step S654, otherwise terminates.
S654:Into macro base station coverage, the minimum activated state capacity of current business load shares base station transmission SLEEP instruction.
Then, above step S640 to 654 is repeated, until step S640 or step S653 judged result is no, or the activated state capacity in macro base station coverage shares base station and fully enters sleep state.
For ease of statement, the business load of the preset times obtained in step S652 can uniformly be designated as the second business load with the preset times business load obtained in step S331, to be made a distinction with the first business load obtained in above-mentioned steps S310.It should be noted that, the preset times business load obtained in step S331 is uniformly designated as the second business load, it is identical to be not intended that the business load obtained every time, in second business load of preset times, the business load obtained every time can be with identical, can also be different, depending on the actual traffic load situation in macro base station coverage.Equally, during above step S640 to 654 is repeated, it can uniformly be remembered in the business load of the acquisition repeated every time by repeating the business load of the preset times of step S652 acquisitions.For example, the business load for the preset times that first time repeat step S652 is obtained can uniformly be designated as the 3rd business load, the second business obtained with performing step S652 with the first business load and first time that are obtained in above-mentioned steps S310 is born
Load makes a distinction.It should be noted that, for the first time and repeat the business load of preset times second and the 3rd business load obtained in step S652, it is identical to be not intended that the business load obtained every time, in the second business load and the 3rd business load of preset times, the business load obtained every time can be with identical, can also be different, depending on the actual traffic load situation in macro base station coverage.In above step S340, when the business load occupancy determined in step S320 is more than or equal to the second thresholding, sleep state capacity that can be directly into macro base station coverage shares base station transmission activation instruction, can continue to monitor macro base station coverage in business load for a period of time after, when business load occupancy in the macro base station coverage is still greater than or equal to the second thresholding, the sleep state capacity into macro base station coverage shares base station transmission activation instruction again, now, above step S340 further comprises step as shown in Figure 7：
S341:If the business load occupancy determined in step S320 is more than or equal to the second thresholding, and the capacity shares base station and is in sleep state, obtains the business load in the macro base station coverage of preset times.Wherein, for the selection of preset times, the present embodiment does not do any limitation, specifically the length of more obvious time can be changed according to the business load of macro base station coverage in daily statistics determine preset times number, naturally it is also possible to set according to the demand of operator.
S342:According to the business load in the macro base station coverage of the preset times obtained in step S341, the business load occupancy in the macro base station coverage of preset times is determined.
S343:If the business load occupancy determined in step S342 is all higher than or equal to the second thresholding, shares base station to the capacity and send activation instruction.
So; through monitoring after a while; business load rise interim in macro base station coverage can be avoided; in the case of returning to relatively low business load again quickly; base station is shared to sleep state capacity and sends activation instruction; sleep state capacity is shared base station and entered after activated state, and macro base station business load is relatively low, in addition it is also necessary to activated state capacity is shared base station repeating into sleep state again.
In the preferred embodiment, two business load report cycle period 1 Tlong and second round Tshort of cell configuration of base station can be shared for macro base station and activated state capacity.Wherein period 1 Tlong is more than second round Tshort.In daily monitoring, macro base station and activated state capacity are shared into the small of base station
Business load report cycle configuration period 1 Tlong in area.That is in above step S310, the business load in macro base station coverage is obtained using period 1 Tlong.When finding that business load occupancy is less than or equal to the first thresholding; the business load report cycle that macro base station and activated state capacity are shared to the cell of base station is adjusted to second round Tshort; to utilize the business load of macro base station described in shorter cycle monitoring; i.e. in above step S341, the business load in the macro base station coverage of preset times is obtained using second round.Shorten business load report cycle to be advantageous in that; if there is zooming trend in the business load in macro base station coverage; shorten business load report cycle, be adapted to this trend, quick activated sleep state capacity shares the effect of base station during reaching that business load amount rises.For example; in office building region; obvious ascendant trend occurs in business load amount period that is on duty; and peak occurs within an of short duration time in this trend, has crossed after this peak, business load amount can keep balance; therefore; shorten business load report cycle, be beneficial to adapt to business load ascendant trend, so that quick activated sleep state capacity shares base station.
In addition, the capacity of possible more than one sleep state shares base station in macro base station coverage.And the trend of business load amount rising is there may be in macro base station coverage; so with the rising of business load amount; the sleep state capacity of activation shares the possible more than one in base station; even as business load amount rises to a certain extent, it is necessary to which the capacity for activating all sleep states shares base station.In this case, it disposably can share base station to the capacity of all or part of sleep states and send activation instruction, can also send one by one.
Preferably, the business load size that can be shared after base station activation can be shared according to sleep state capacity, enter to send activation instruction according to order from big to small.Relative to once activating in the case that multiple sleep state capacity share base station; after some sleep state capacity shares base station activation; business load in macro base station coverage has met requirement; other sleep state capacity may not necessarily be then then turned on and share base station, unnecessary energy waste can be avoided.Now, the communication means that the embodiment of the present invention is provided can include step as shown in Figure 8：
