A kind of method for adjustment voltage of power amplifier provided in an embodiment of the present invention, as shown in figure 1, the method includes：
S101, base station obtain carrier traffic.
Carrier wave is used to carry communication service, and using carrier-wave transmission, we can be by the signal loading of data to carrier wave
Signal on, and then complete the transmission of signal.For example, the acoustical signal of two user's communications just can be carried in the signal of carrier wave
On.
Base station can periodically be detected and obtain the carrier traffic being carried on all carrier waves, and then passes through carrier wave industry
Business amount arranges operating carriers number, and specific Bearer traffic quantity measuring method those skilled in the art is capable of, and the present invention is real
Apply example not to be limited.
S102, base station arrange operating carriers number according to carrier traffic.
Base station arranges operating carriers number according to the carrier traffic getting, and exemplary, base station is according to Bearer traffic
The increase of amount or reduce and to be switched on or off carrier wave, even carrier traffic is more than the first pre-determined threshold, then open corresponding carriers,
So that operating carriers number increases to the corresponding carrier number of carrier traffic, if carrier traffic is less than the second pre-determined threshold,
Turn off corresponding carriers, so that operating carriers number reduces carrier number corresponding to carrier traffic.
For example, currently there are two carrier waves of A, B in work, that is, operating carriers number is 2, the carrier wave industry that two carrier waves are carried
Business amount is 50 it will be assumed that the value of the first pre-determined threshold is 60, then when the carrier traffic being carried on two carrier waves increases
And during more than 60, carrier wave C is then opened in base station, and then now just there are three carrier waves in work, likewise, we assume that second is default
The value of thresholding is 30, then when the carrier traffic being carried on two carrier waves reduces and is less than 30, base station then turns off in A, B
A carrier wave, and then now have a carrier wave work.It is understood that so that carrier traffic reduces as a example, if two
When the carrier traffic being carried on carrier wave reduces to 20, and 10 business are carried on A carrier wave, B carrier wave also carries 10
Individual business, then base station can be transferred to the business carrying on carrier wave one of in A or B on another carrier wave, and turns off not
The carrier wave of bearer traffic again, specific service transfer method those skilled in the art is capable of, and the embodiment of the present invention is simultaneously
It is not limited.
It is pointed out that the embodiment of the present invention carries according to carrier traffic setting work simply by illustrating base station
The process of wave number, specific first pre-determined threshold, the value of the second pre-determined threshold can be set according to practical situation, the present invention
Embodiment is not limited, but also should be within the protection domain of the embodiment of the present invention.
S103, base station arrange maximum bias voltage and the highest of power amplifier corresponding with operating carriers number according to operating carriers number
Slicing thresholding.
Base station, can be according to the setting of operating carriers number and this operating carriers after arranging operating carriers number according to carrier traffic
The corresponding maximum bias voltage of number and highest slicing thresholding.
Here, need to be divided into two kinds of scenes to be described in detail, a kind of is that base station is capable of power amplifier is moved
The scene of state pressure regulation, another kind is the scene that the dynamic voltage adjustment to power amplifier can not be realized in base station.
Dynamic voltage adjustment refers to, operating carriers number one timing, and base station can adjust according to the increase of carrier traffic or reduction
The bias voltage of power amplifier and the size of slicing thresholding.For example, currently there are two carrier waves of A, B in work, two carrier waves of A, B carry
Carrier traffic be 60, bias voltage is adjusted to 25V, and slicing thresholding is adjusted to 10dB, then when carrier traffic is decreased to
When 50, bias voltage can be adjusted to 24V by base station, and slicing thresholding is adjusted to 9dB, when carrier traffic is decreased to 40, base
Stand and bias voltage can be adjusted to 23V, slicing thresholding is adjusted to 8dB, when carrier traffic rises, carrier traffic rises
How much, bias voltage all can be adjusted to 25V by base station, and slicing thresholding is adjusted to 10dB.I.e. when operating carriers number one timing, partially
Put voltage and slicing thresholding can change with the change of carrier traffic, and the principle in accordance with " fast liter is dropped slowly ".
It should be noted that the dynamic voltage adjustment that the embodiment of the present invention is proposed, bias voltage is divided grade, but specifically
It is divided into several grades, and the corresponding occurrence of each grade, the present invention is not limited, and can be set according to actual situation
Put.For example, in UMTS (Universal Mobile Telecommunications System, UMTS) system
In system, only R99 business when, the bias voltage of power amplifier can be divided into eight grades, there is HSPA (High Speed
Packet Access, high speed packet data access) business when, the bias voltage of power amplifier can be divided into four grades.
When base station is capable of the dynamic voltage adjustment to power amplifier, base station carries according to the setting of operating carriers number and work
Wave number corresponding maximum bias voltage and highest slicing thresholding, maximum bias voltage here and highest slicing thresholding refer to power
The maximum bias voltage corresponding to this operating carriers number of amplifier and highest slicing thresholding, for example, have operating carriers number to be 2
When, the correspondence of base station setting is 25V with the maximum bias voltage of 2 carrier waves, and highest slicing thresholding is 10dB, carrier traffic
Reducing and exceed the portfolio that present operating voltage serviced can make base station that bias voltage and slicing thresholding are reduced by one etc.
Level；When carrier traffic increases, base station directly bias voltage is set to 25V and slicing thresholding is set to 10dB, that is, reduce
It is to reduce by grade step by step, and raising is directly to be upgraded to this carrier number corresponding maximum bias voltage and highest slicing door
Limit is it is achieved that " fast rise slow drop ".
When the dynamic voltage adjustment to power amplifier can not be realized in base station, base station is according to the setting of operating carriers number and work
Carrier number corresponding maximum bias voltage and highest slicing thresholding, now, if operating carriers number does not change, then biasing
Voltage and slicing thresholding all do not change, and only operating carriers number changes, and base station ability is to bias voltage and slicing thresholding
Reset, for example, when there being two carrier operation of A, B, maximum bias voltage is 25V, and highest slicing thresholding is 10dB,
No matter how carrier traffic changes, bias voltage is 25V and slicing thresholding is 10dB, when there being tri- carrier wave works of A, B, C
When making, base station resets maximum bias voltage 28V, and highest slicing thresholding is 12dB, as long as carrier traffic does not cause work
The change of carrier number, then still using bias voltage 28V, slicing thresholding is operated for 12dB.
In sum, if dynamic voltage adjustment characteristic is opened, then reduce in carrier traffic and be less than present operating voltage
During the scope being serviced, the bias voltage of power amplifier and slicing thresholding are reduced downwards a grade；If Bearer traffic
Amount increases, then the bias voltage of power amplifier is increased to the maximum bias voltage corresponding to work at present carrier number, slicing
Thresholding also improves the highest slicing thresholding corresponding to current carrier number.If dynamic voltage adjustment characteristic is not turned on, no matter carrier wave
How portfolio changes, and the bias voltage of power amplifier and slicing thresholding are respectively equal to the maximum bias voltage corresponding to operating carriers number
With highest slicing thresholding.
And then, power amplifier is worked with slicing thresholding with the bias voltage after adjusting.
Method for adjustment voltage of power amplifier provided in an embodiment of the present invention, by obtaining carrier traffic, and according to carrier wave industry
After business amount setting operating carriers number, according to the setting of operating carriers number and this operating carriers number corresponding maximum bias voltage and highest
Slicing thresholding.By the program, can be according to the operating carriers number of change, setting maximum bias corresponding with operating carriers number electricity
Pressure and highest slicing thresholding, so that power amplifier is when portfolio changes, can be operated in energy-conservation, most reliable biasing
Voltage is worked with slicing thresholding, and then reduces the energy consumption of base station.
Method for adjustment voltage of power amplifier provided in an embodiment of the present invention, as shown in Fig. 2 when base station is capable of to power amplification
During the dynamic voltage adjustment of device, the method includes：
S201, base station obtain carrier traffic.
Carrier wave is used to carry communication service, and using carrier-wave transmission, we can be by the signal loading of data to carrier wave
Signal on, and then complete the transmission of signal.For example, the acoustical signal of two user's communications just can be carried in the signal of carrier wave
On.
Base station can periodically be detected and obtain the carrier traffic being carried on all carrier waves, and then passes through carrier wave industry
Business amount arranges operating carriers number, and specific Bearer traffic quantity measuring method those skilled in the art is capable of, and the present invention is real
Apply example not to be limited.
S202, base station arrange operating carriers number according to carrier traffic.
Base station arranges operating carriers number according to the carrier traffic getting, and exemplary, base station is according to Bearer traffic
The increase of amount or reduce and to be switched on or off carrier wave, even carrier traffic is more than the first pre-determined threshold, then open corresponding carriers,
So that operating carriers number increases to the corresponding carrier number of carrier traffic, if carrier traffic is less than the second pre-determined threshold,
Turn off corresponding carriers, so that operating carriers number reduces carrier number corresponding to carrier traffic.
For example, currently there are two carrier waves of A, B in work, that is, operating carriers number is 2, the carrier wave industry that two carrier waves are carried
Business amount is 50 it will be assumed that the value of the first pre-determined threshold is 60, then when the carrier traffic being carried on two carrier waves increases
And during more than 60, carrier wave C is then opened in base station, and then now just there are three carrier waves in work, likewise, we assume that second is default
The value of thresholding is 30, then when the carrier traffic being carried on two carrier waves reduces and is less than 30, base station then turns off in A, B
A carrier wave, and then now have a carrier wave work.It is understood that so that carrier traffic reduces as a example, if two
When the carrier traffic being carried on carrier wave reduces to 20, and 10 business are carried on A carrier wave, B carrier wave also carries 10
Individual business, then base station can be transferred to the business carrying on carrier wave one of in A or B on another carrier wave, and turns off not
The carrier wave of bearer traffic again, specific service transfer method those skilled in the art is capable of, and the embodiment of the present invention is simultaneously
It is not limited.
It is pointed out that the embodiment of the present invention carries according to carrier traffic setting work simply by illustrating base station
The process of wave number, specific first pre-determined threshold, the value of the second pre-determined threshold can be set according to practical situation, the present invention
Embodiment is not limited, but also should be within the protection domain of the embodiment of the present invention.
S203, base station arrange maximum bias voltage and the highest of power amplifier corresponding with operating carriers number according to operating carriers number
Slicing thresholding.
Base station, can be according to the setting of operating carriers number and this operating carriers after arranging operating carriers number according to carrier traffic
The corresponding maximum bias voltage of number and highest slicing thresholding.
For example, in a base station that can configure three carrier waves,
If current operating carriers number is 1, maximum bias voltage is set to 22v, and highest slicing thresholding is to be set to
7dB.
If current operating carriers number is 2, maximum bias voltage is set to 25v, and highest slicing thresholding is to be set to
10dB.
If current operating carriers number is 3, maximum bias voltage is set to 28v, and highest slicing thresholding is to be set to
12dB.
Table 1
Can be it is clearly noted not only that when base station be capable of dynamic voltage adjustment from table 1, carrier traffic, bias voltage, slicing
Relation between thresholding, carrier number, maximum bias voltage and highest slicing thresholding.
You need to add is that, the dynamic voltage adjustment that the embodiment of the present invention is proposed, bias voltage has been divided grade, but specifically
It is divided into several grades, and the corresponding occurrence of each grade, this programme is not limited, and can be set according to actual situation
Put.For example, in the umts system, only R99 business when, the bias voltage of power amplifier can be divided into eight grades, exists
During HSPA business, the bias voltage of power amplifier can be divided into four grades.
S204, base station arrange bias voltage and the slicing door of power amplifier corresponding with carrier traffic according to carrier traffic
Limit.
Specifically, if carrier traffic drops to the 3rd pre-determined threshold, reset work(corresponding with carrier traffic
The bias voltage put and slicing thresholding, if carrier traffic rises, by the bias voltage of power amplifier corresponding with carrier traffic
It is set to maximum bias voltage, the slicing thresholding of power amplifier corresponding with carrier traffic is set to highest slicing thresholding.
When base station is capable of the dynamic voltage adjustment to power amplifier, reduces in carrier traffic and be less than work at present
During the scope that voltage is serviced, the bias voltage of power amplifier and slicing thresholding are reduced a grade downwards, if carrier wave
Portfolio increases, and no matter portfolio increase is how many, all the bias voltage of power amplifier is increased to work at present carrier number institute
Corresponding maximum bias voltage, slicing thresholding also improves the highest slicing thresholding corresponding to current carrier number, it is achieved thereby that
" fast liter is dropped slowly ".
Adjustment process the following detailed description of " fast liter is dropped slowly "：
(1) " the fast liter " when carrier traffic increases
For example, in a base station that can configure 3 carrier waves, currently there are two carrier waves of A, B in work, two carrier waves of A, B
The carrier traffic of upper carrying is 35, and bias voltage is 23V, and slicing thresholding is 8dB, then
If carrier traffic is when 35 are increased to 55, bias voltage is adjusted to 25V by 23v by base station, and slicing thresholding is adjusted
Whole is to rise a height of 10dB by 8dB；
If carrier traffic is when 35 are increased to 45, base station is also that by 23v, bias voltage is adjusted to 25V, slicing door
Limit is adjusted to and rises a height of 10dB by 8dB；
Wherein 25v and 10dB is the maximum bias voltage and highest slicing thresholding corresponding to two carrier waves.It is pointed out that
Three carrier waves in base station when all opening corresponding maximum bias voltage and highest slicing thresholding be 28v and 12dB.Special instruction
It is that the present invention, when carrier traffic increases, allows bias voltage rise to 25v rather than 28v, slicing thresholding improves to 10dB not
It is 12dB, because currently only two carrier waves are in running order.This is one of important innovations point of the present invention.
(2) " the slow fall " when carrier traffic reduces
For example, currently there are two carrier waves of A, B in work, the carrier traffic that two carrier waves of A, B carry is 60, biased electrical
Press as 25V, slicing thresholding is 10dB, then
If carrier traffic is when 60 are decreased to 45, bias voltage is adjusted to 24V by base station, and slicing thresholding is adjusted to
9dB；
If carrier traffic is when 60 are decreased to 35, bias voltage and slicing thresholding are lowered a grade by base station, that is,
Bias voltage is to be changed into 24V from 25v, and slicing thresholding is adjusted to 9dB by 10dB；If next periodic traffic is still 35, then base
Stand and again bias voltage and slicing thresholding are lowered a grade, that is, bias voltage is to be changed into 23V from 24v, and slicing thresholding is adjusted by 9dB
Whole for 8dB；
In sum, when operating carriers number one timing, bias voltage can change with the change of carrier traffic, and
Principle in accordance with " fast liter is dropped slowly ".
And then, power amplifier is worked with slicing thresholding with the bias voltage after adjusting.
As shown in figure 3, when the dynamic voltage adjustment to power amplifier can not be realized in base station, the method includes：

On.
Base station can periodically be detected and obtain the carrier traffic being carried on all carrier waves, and then passes through carrier wave industry

Turn off corresponding carriers, so that operating carriers number reduces carrier number corresponding to carrier traffic.
For example, currently there are two carrier waves of A, B in work, that is, operating carriers number is 2, the carrier wave industry that two carrier waves are carried
Business amount is 50 it will be assumed that the value of the first pre-determined threshold is 60, then when the carrier traffic being carried on two carrier waves increases
And during more than 60, carrier wave C is then opened in base station, and then now just there are three carrier waves in work, likewise, we assume that second is default
