Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete
Site preparation is described.
Occur significantly declining to solve the general power of wideband Multi-Mode Base Station, cause the communication matter of terminal under each standard
The problem of quantitative change is poor, the embodiment of the present invention provides a kind of method of power distribution, as shown in figure 1, this method includes：
Step 101, base station obtain the corresponding portfolio of each standard and each standard corresponding end in Target cell respectively
Hold number.
It is understood that wideband Multi-Mode Base Station can manage multiple cells, the embodiment of the present invention is only with wideband multimode base
Illustrate the method for power distribution exemplified by one cell of station administration.For example, the cell A that is managed of wideband Multi-Mode Base Station support GSM,
WCDMA and FDD Long Term Evolution (Frequency Division Duplexing Long Term Evolution, below
Abbreviation FDD-LTE) and time division duplex Long Term Evolution (Time Division Duplexing Long Term Evolution, with
Lower abbreviation TDD-LTE) four kinds of standards.
Step 102, base station calculate the corresponding portfolio ratio of each standard in Target cell respectively.
Wherein, portfolio ratio accounts for the ratio of Target cell total traffic for each corresponding portfolio of standard in Target cell
Example.
It is assumed that after calculating, each self-corresponding portfolio ratio of 4 standards is 0.05,0.45,0.25,0.25 in cell A,
I.e. in cell a, the use of the corresponding portfolio ratio of terminal of GSM standards is 0.05, the terminal using WCDMA standards is corresponding
Portfolio ratio is 0.45, the use of the corresponding portfolio ratio of the terminal of FDD-LTE standards is 0.25, uses TDD-LTE standards
The corresponding portfolio ratio of terminal be 0.25.
Step 103, base station calculate the corresponding number of terminals ratio of each standard in Target cell respectively.
Wherein, number of terminals ratio accounts for the ratio of the total number of terminals of Target cell for each corresponding number of terminals of standard in Target cell
Example.
For example, through calculating, in cell a, each self-corresponding number of terminals ratio of 4 standards be 0.04,0.46,0.2,
0.3。
If step 104, base station determine that the general power of Target cell is less than power threshold, respectively according to every in Target cell
The individual corresponding portfolio ratio of standard and the corresponding number of terminals ratio of each standard, redistribute the corresponding work(of each standard
Rate.
It should be noted that only when the general power of Target cell is less than power threshold, terminal is logical in Target cell
Letter quality has been only possible to significant decline.For example, the general power of Target cell is 200W, when the general power of Target cell is dropped to
During 160W, the terminal under each standard still is able to be normally carried out communication, and when the general power of Target cell is less than 150W, very may be used
Terminal under some standards of energy can not be normally carried out communication, therefore, it can regard 150W as power threshold.It may be appreciated
Be, in embodiments of the present invention, when the communication quality of terminal is not remarkably decreased not to Target cell in each standard
Corresponding power is adjusted, and it is corresponding only just to redistribute each standard when the general power of Target cell is less than power threshold
Power, so as to optimize the communication quality of terminal under each standard.
The method of power distribution provided in an embodiment of the present invention, obtains and calculates the corresponding portfolio of each standard in cell
Ratio and number of terminals ratio, when multimode wideband base station emergent power declines, with that can not optimize under each standard in the prior art
The communication quality of terminal is compared, in embodiments of the present invention, can be according to the corresponding portfolio ratio of each standard and number of terminals
Ratio adaptively redistributes the corresponding power of each standard so that wideband Multi-Mode Base Station more can be redistributed balancedly
Each corresponding power of standard, it is to avoid by the larger power distribution standard small to power demand, caused by power dissipation,
Meanwhile, it also avoid the less power distribution standard big to power demand, so as to ensure that under the big standard of power demand
The communication quality of terminal, and then the communication quality of terminal under each standard can be optimized.
It should be noted that when the general power of Target cell is less than power threshold, each standard correspondence need to be redistributed
Power, based on this, as shown in Fig. 2 in another implementation provided in an embodiment of the present invention, step 104, respectively basis
Each corresponding portfolio ratio of standard and the corresponding number of terminals ratio of each standard, redistribute each system in Target cell
The corresponding power of formula includes：
Step 201, base station determine that portfolio ratio is maximum in Target cell, and number of terminals ratio is more than or equal to number of terminals
The standard of proportion threshold value is advantage standard；Determine that portfolio ratio is less than portfolio proportion threshold value, and number of terminals ratio is less than eventually
The standard for holding number proportion threshold value is inferior position standard, and the standard in addition to advantage standard and inferior position standard is middle standard.
It is assumed that default portfolio proportion threshold value is 0.4, number of terminals proportion threshold value is 0.05, with reference to above-mentioned citing,
In Target cell, the corresponding portfolio ratios of WCDMA are maximum, and the number of terminals 0.46 communicated by WCDMA>Number of terminals ratio
Example threshold value 0.05, then regard WCDMA as advantage standard.
It should be noted that in embodiments of the present invention, in order to avoid illegal terminal takes the mode of flow attacking to send
Mass data, takes the resources such as the substantial amounts of bandwidth of communication network, communication network is made a very bad impression, when the corresponding industry of standard A
When business amount ratio is maximum, the number of terminals ratio that data are sent using standard A need to be judged, if sending data using standard A
Number of terminals ratio be less than number of terminals proportion threshold value, illustrate that using the terminal that standard A sends data be illegal terminal, accordingly,
Standard A is illegal standard.
It is understood that when there is illegal standard in Target cell, can be descending according to portfolio ratio
Order is ranked up to the corresponding portfolio ratio of each standard, then chooses the sequence of portfolio ratio after illegal standard
The maximum standard of portfolio ratio is used as advantage standard.For example, there is following 5 kinds of standards, by 5 kinds of standards according to portfolio ratio by
Small order is arrived greatly to be arranged as：Standard A, standard B, standard C, standard D, standard E.If standard A is illegal standard, standard is judged
Whether the corresponding number of terminals ratios of B are less than number of terminals proportion threshold value, if the corresponding number of terminals ratios of standard B are less than number of terminals ratio
Threshold value, then standard B also serves as illegal standard, and then judges whether standard C number of terminals ratio is less than number of terminals proportion threshold value, if
The corresponding number of terminals ratios of standard C are more than or equal to number of terminals proportion threshold value, then regard standard C as advantage standard.
Illustrate as described above, the corresponding portfolio ratios 0.05 of GSM<Portfolio proportion threshold value 0.4, and the corresponding terminals of GSM
Number ratio 0.04<Number of terminals proportion threshold value 0.05, then regard GSM as inferior position standard
It is understood that after determination advantage standard and inferior position standard, will be in addition to advantage standard and inferior position standard
FDD-LTE and TDD-LTE be used as middle standard.
Step 202, base station calculate the corresponding original configuration power of advantage standard and the corresponding pre-configured work(of advantage standard
Rate.
Wherein, the corresponding configuration power of each standard before original configuration power is critical moment, pre-configured power is to face
The corresponding configuration power of each standard after boundary's moment, critical moment is determines that the general power of Target cell is less than power threshold
Moment.
The corresponding original configuration power of advantage standard isThe corresponding pre-configured work(of advantage standard
Rate isPbefFor the sum of each self-corresponding original configuration power of each standard in Target cell, servi
For the corresponding portfolios of standard i,For the sum of each each self-corresponding portfolio of standard in Target cell.
First, with reference to the critical moment in for example bright embodiment of the present invention, such as wideband Multi-Mode Base Station is stable normal
During work, the terminal that the general power of Target cell is maintained in 200W, and Target cell can be normally carried out communication.Afterwards, exist
Moment A, the general power of Target cell drops to 100W suddenly, now, and wideband Multi-Mode Base Station detects the general power of Target cell
(100W) is less than power threshold (150W), then wideband Multi-Mode Base Station regard moment A as critical moment.
It should be noted that before calculating that advantage standard is corresponding and reconfiguring power, in order to avoid using illegal standard
Terminal malicious attack communication network, need to be adjusted to 0 by the corresponding power of illegal standard.
With reference to the citing of above-mentioned steps, it is assumed that power threshold is 150W, if wideband Multi-Mode Base Station is in the work of normal table
When making state, the general power of Target cell maintains 200W, and the corresponding original configuration power of advantage standard WCDMA isAfterwards, the general power of Target cell drops to 100W suddenly, then
As critical moment at the time of the general power of Target cell to drop to 100W suddenly, in the general power of critical moment Target cell
For 100W, the corresponding pre-configured power of advantage standard WCDMA
If step 203, base station determine that the corresponding original configuration power of advantage standard is less than in critical moment Target cell
General power, then determine advantage standard according to the corresponding original configuration power of advantage standard and the corresponding pre-configured power of advantage standard
It is corresponding to reconfigure power.Wherein, the corresponding power that reconfigures of advantage standard is Psup,i=Pbef,i*k1+Paft,i*k2, k1、k2For
Power regulation factor, k1+k2=1.
With reference to the citing in step 202, before critical moment, need what is distributed for advantage standard according to portfolio ratio
Original configuration power is 90W, to ensure the communication quality of the terminal using advantage standard, after critical moment, according to business
Amount ratio need to be that the pre-configured power of advantage standard distribution is 45W.In order to distribute more reasonable for advantage standard in Target cell
Reconfigure power, in embodiments of the present invention, be provided with power adjustment parameters k1And k2.By adjusting k1And k2, can make excellent
Gesture standard is corresponding to reconfigure the corresponding original configuration power of power infinite approach advantage standard, or makes advantage standard corresponding
The corresponding predistribution power of power infinite approach advantage standard is reconfigured, or the corresponding performance number of advantage standard is adjusted to former
Any performance number begun between configuration power and pre-configured power.
With reference to the example above, it is assumed that k1For 0.8, k2For 0.2, before critical moment, WCDMA standards are corresponding original to match somebody with somebody
Put power 90W<The general power 100W of critical moment Target cell.Accordingly, it is determined that advantage standard WCDMA is corresponding to reconfigure power
For Psup,i=90W*0.8+45W*0.2=81W.
The corresponding power that reconfigures of inferior position standard is adjusted to 0 by step 204, base station.
As a kind of achievable mode, after critical moment, the corresponding power that reconfigures of inferior position standard can be adjusted
Whole is 0, and the corresponding power distribution of inferior position standard other standards larger to portfolio are used, and lifting portfolio ratio is big
The communication quality of terminal under standard.
Step 205, base station calculate dump power, and dump power is the general power and advantage system in critical moment Target cell
The corresponding difference for reconfiguring power of formula.
With reference to the example above, dump power is obtained for 100W-81W=19W.
Step 206, base station adjust that each middle standard is corresponding heavy to match somebody with somebody according to portfolio ratio and dump power respectively
Put power.
Wherein, the corresponding power that reconfigures of each middle standard isPleftFor dump power,
servjFor the corresponding portfolios of middle standard j,For each self-corresponding portfolio of each middle standard in Target cell
Sum.
With reference to the example above, to middle standard TD-LTE and FDD-LTE, obtain that middle standard TD-LTE is corresponding to be reconfigured
Power is
The corresponding power that reconfigures of middle standard FDD-LTE is
The method of power distribution provided in an embodiment of the present invention, it is corresponding according to the standard of each in Target cell respectively first
The type of each standard of portfolio ratio and number of terminals ratio-dependent, then calculates the corresponding original configuration power of advantage standard
Pbef,iPre-configured power P corresponding with advantage standardaft,iIf it is corresponding that the corresponding original configuration power of advantage standard is less than its
Pre-configured power, then the power distributed for advantage standard is Psup,i=Pbef,i*k1+Paft,i*k2, to ensure as the distribution of advantage standard
More sufficient power, and the corresponding power of inferior position standard is adjusted to 0, to cause the corresponding power distribution of inferior position standard to industry
Other big standards of business amount ratio, finally, calculate dump power, and dump power is made according to portfolio pro rate to middle
Formula.It can be seen that, in embodiments of the present invention, after the type by each standard of portfolio ratio and number of terminals ratio-dependent, just
More power can be distributed for the standard of portfolio large percentage, be that the less standard of portfolio distributes less power, from
And make it that the power for the distribution of each standard is more balanced, optimize the communication quality of terminal under every kind of standard.
It should be noted that when the corresponding original configuration power of advantage standard is more than the general power of critical moment Target cell
When, illustrate that wideband Multi-Mode Base Station can not distribute sufficiently large power for advantage standard, now, it should be according to portfolio ratio
Advantage standard and other standard distribution powers in addition to advantage standard, based on this, provided in an embodiment of the present invention another
Plant in implementation, as shown in figure 3, step 202, the corresponding original configuration power of calculating advantage standard and advantage standard correspondence
Pre-configured power after, can also carry out step 301.
If the corresponding original configuration power of step 301, advantage standard is more than the general power in critical moment Target cell,
The corresponding power of the standard of each in Target cell is readjusted in base station according to portfolio ratio, and the corresponding power of each standard isWherein, PaftFor in the general power of critical moment Target cell, servkFor the corresponding portfolios of standard k,For the corresponding portfolio ratios of standard k.
It is assumed that before critical moment, the general power of wideband Multi-Mode Base Station maintain in 200W, cell A GSM, WCDMA and
TDD-LTE and the corresponding portfolio ratio of tetra- kinds of standards of FDD-LTE are respectively 0.05,0.6,0.2,0.15, then advantage standard
The corresponding original configuration power of WCDMA isAfterwards, wideband is more
The power of mould base station declines suddenly, and the general power caused in critical moment Target cell is 100W.Because advantage standard is corresponding
Original configuration power (120W) is more than the general power 100W of critical moment Target cell, then obtains each system according to portfolio ratio
The power of formula is as follows：
The corresponding power of advantage standard WCDMA isInferior position standard
The corresponding power of GSM isThe corresponding power of middle standard TDD-LTE isThe corresponding power of middle standard FDD-LTE is

And the corresponding number of terminals ratio of each standard.
It should be noted that for cell A, before power adjustment flow is performed, GSM, WCDMA, FDD-LTE and TDD-
Each self-corresponding portfolio ratio of tetra- standards of LTE is 0.05,0.45,0.25,0.25.Flow is being adjusted by first time power
Afterwards, in predetermined period, the communication conditions of terminal change under each standard, for example, being communicated using WCDMA standards
Terminal portfolio increasing proportion, and the number of terminals ratio of the terminal communicated using WCDMA standards also increased, this time width
Frequency Multi-Mode Base Station need to redefine the corresponding portfolio ratio of each standard number of terminals ratio corresponding with each standard.For example,
Wideband Multi-Mode Base Station determines that the corresponding portfolio ratio of tetra- standards of GSM, WCDMA, FDD-LTE and TDD-LTE is respectively again
0.05th, 0.65,0.15,0.15, the corresponding number of terminals ratio of these four standards is 0.04,0.56,0.1,0.3.
Step 402, base station are according to the corresponding portfolio ratio of each standard in the Target cell redefined and again
