Fig. 1 is the flow chart for the power sharing method that one embodiment of the invention provides.In the present embodiment, at least two system
The communication system of formula shares same power amplifier, for example, the communication system of the communication system of GSM standards and UMTS standards share it is same
Individual power amplifier.As illustrated, this method includes：
Step 101, the communication of at least one standard in the communication system for each standard for sharing same power amplifier
The power demand of system determines whether that power is carried out between different systems communication system to be shared.
, can be according to the logical of wherein one or more standards for the communication system for each standard for sharing same power amplifier
The power demand of letter system, it is determined that whether having power remaining for the communication system of some standard, it so can determine whether
Power is carried out between different systems communication system to share.
Step 102, if it is determined that carry out power between different systems communication system and share, adjust wherein one or more
The available horsepower of the communication system of standard.
Shared if it is determined that to carry out power between different systems communication system, then can be to wherein one or more

With the associated description with reference to subsequent embodiment.
The method of the present embodiment, when determining that to carry out power shares according to power demand, in different systems communication system
Between carry out power and share, so as to which the power for realizing dynamic flexible between the communication system of at least two standards is shared.
It is further to note that if at least one in the communication system of each standard of shared same power amplifier is made
The communication system of formula also uses the available work of other power amplifiers, the then communication system of above-mentioned wherein one or more standards of adjustment simultaneously
Rate includes：Adjust the shared power amplifier and other one or more power amplifiers is used simultaneously other one or more work(
The ratio for the power that the communication system put takes, simultaneously should using the communication system occupancy of other one or more power amplifiers to reduce
Power on shared power amplifier.
Wherein, the shared power amplifier and the communication system for being used simultaneously other power amplifiers occupancy of other power amplifiers are adjusted
The mode of the ratio of power can have it is a variety of, as long as can realize reduce that described while using other power amplifiers communication systems take should
The purpose of power on shared power amplifier.For example, it is assumed that UMTS and GSM shares the first power amplifier, and GSM is also simultaneously simultaneously
The first power amplifier and the second power amplifier can be then adjusted using the second power amplifier by the ratio of the GSM power taken, the is taken to reduce GSM
Power on one power amplifier, because the general power needed for GSM is fixed, therefore, when GSM takes more power on the second power amplifier
When, power shared on the first power amplifier GSM can be reduced, so that the power of the first power amplifier is accounted for by UMTS as far as possible
With.A kind of mode therein can be：Preferentially using the power distribution of the second power amplifier to GSM as its available horsepower.Need to illustrate
, different demands is configured with according to different, sometimes will be uniformly using the power of two power amplifiers.Such as in MIMO
（Multiple Input Multiple Output, Multiinputoutput）Under scene, GSM can be now caused uniformly to use as far as possible
The power of first power amplifier and the second power amplifier.Wherein it is possible to power is shared from GSM to UMTS using hair diversity or other modes.
Fig. 2 is the flow chart for the power sharing method that another embodiment of the present invention provides, will be shared same in the present embodiment
The communication system of multiple standards of power amplifier is referred to as the communication system of the first standard and the communication system of other one or more standards
System, as illustrated, including：
Step 201, in predetermined period, according to the communication of the power demand of the communication system of the first standard and the first standard
The available horsepower of system obtains the sharable dump power of the communication system of the first standard.
Specifically, the sharable dump power of each standard communication can be known in the following way：
When predetermined period reaches, the general power that the communication system of a standard is currently configured is subtracted into current power needs
Ask, obtained difference is sharable dump power；Or when predetermined period reaches, the communication system of a standard is worked as
The available horsepower of preceding configuration subtracts current power demand and reserved power, and obtained difference is sharable dump power；Or
Constant power value or fixed proportion in the general power that the communication system of one standard is currently configured can be shared as described in
Dump power.
Wherein, current power demand refers to that the communication system of a standard runs required power to remain current.
For example, the current power demand of GSM standards refers to maximum of the current each slot requirements power of 8 time slots with, wherein wrapping
Power containing pilot transmission.In time slot time division multiple access（Time Division Multiple Access, referred to as：TDMA）In technology,
One frame is made up of 8 time slots.GSM pilot transmission power refers in BCCH (Broadcast Control
Channel, referred to as：BCCH power used during transmitting pilot signal in).Make because pilot signal generally has before offer to code
To divide the function such as access channel time limit, coherent demodulation phase reference, be very important signal, its transmission power will keep constant,
Therefore used not as communication system of the sharable dump power for other standards.
Wherein, reserved power refers to the idle power for keeping for a standard to use, in case the burst service that may be predicted
Arrival or for meeting power demand of the communication system of the standard in next predetermined period.The reserved power can be with
Any number is arranged to according to being actually needed.
It should be noted that predetermined period herein can be set according to being actually needed.And the first standard of the above is logical
Letter system can be any one in the communication system for the multiple standards for sharing power amplifier.
Step 202, judge whether to agree to receive the according to the power demand of the communication system of other one or more standards
The sharable dump power of the communication system of one standard.
Specifically, if the network load of the communication system of other one or more standards, such as high-speed slender body theory
（High Speed Downlink Packet Access, referred to as：HSDPA）Network load is lighter, it is not necessary to receives shared power
When, then reject the dump power.Or if the remaining time that can be shared of the dump power be less than be available for one or
The minimum effective time that the communication system of other multiple standards uses（Unit ms）, then shared power can also be rejected, with
Too short to the usage time of shared power after avoiding progress power shared, utilization rate is too low.Wherein, remaining time refers to one
In the individual shared cycle, used from the communication system for determining to share to dump power into other one or more standards to the shared week
Phase terminate between this period.
Step 203, if the sharable dump power of the communication system of the first standard meet default shared condition and
The power demand of the communication system of other one or more standards agrees to receive the sharable surplus of the communication system of the first standard
Complementary work rate, shared it is determined that carrying out power between different systems communication system.
Specifically, if the sharable dump power of the communication system of the first standard is more than or equal to the first thresholding,
Determine that the sharable dump power of the communication system of the first standard meets default shared condition；Or if the first standard
Communication system sharable dump power and the communication system of other one or more standards sharable dump power
Difference when being more than or equal to the second thresholding, determine the communication system of the first standard sharable dump power meet it is default
Shared condition.Certainly, according to different demands, there can also be other modes to determine being total to for the communication system of the first standard
Whether the dump power enjoyed meets default shared condition, will not enumerate herein.If the in addition, communication system of the first standard
When the sharable dump power of system is unsatisfactory for default shared condition, the communication system of another standard can be redefined
Sharable dump power whether meet default shared condition, if the communication system of another standard is sharable
Dump power meets default shared condition, and the power of the communication system can be shared to the communication system of other standards.
For example, it is assumed that the communication system of the first standard is GSM, if GSM dump powers are more than or equal to the first thresholding,
Illustrate that the power demand of now GSM standards is relatively low, a part of GSM dump powers can be shared to other standards；Otherwise illustrate
Now the power demand of GSM standards in itself is also very high, should not share power to other standards, in order to avoid influence GSM standards itself
Normal operation.
For another example the communication system for assuming the first standard is GSM, the communication system of other standards is UMTS, if
Warp-wise UMTS patterns have shared power to upper cycle GSM standard, therefore only when the sharable remaining work(of gsm communication system
Just meet shared condition when the difference of rate and UMTS sharable dump power is more than or equal to the second thresholding, to ensure to only have
Power just is shared to UMTS when GSM there are enough dump powers, is total to avoiding frequently carrying out back-off and repeating power
The operation enjoyed, to mitigate system burden.Except GSM and UMTS, can also there are the communication system of other standards, such as Long Term Evolution
(Long Term Evolution, referred to as：LTE), regardless of whether being the communication system of which kind of standard, the thinking of processing be it is similar,
The present embodiment does not enumerate.
It should be noted that being illustrated above exemplified by power is shared into UMTS by GSM, in actual conditions, also may be used
So that power is shared into GSM by UMTS.The numerical value of the thresholding of the above first and the second thresholding can be set according to being actually needed, this hair
Bright embodiment is not limited this.
In addition, if when the communication system of the first standard is GSM, then the logical of the first standard is obtained in above-mentioned steps 201
It can further include before the sharable dump power of letter system：Judging the quantity of the non-master B carrier waves in GSM carrier waves is
It is no to reach default numerical value, if reaching default numerical value, perform the sharable residue for the communication system for obtaining the first standard
The step of power；Wherein, default numerical value can be any positive integer, and main B carrier waves refer to the carrier wave of pilot signal transmitted, non-
Main B carrier waves refer to the carrier wave in addition to main B carrier waves.In gsm, can the carrier waves of the B based on distribution foot in order to ensure its normal operation
Enough power, therefore, substantial amounts of available horsepower can be taken, when the quantity of non-master B carrier waves is enough, there may be a large amount of remaining work(
Rate shares to other one or more communication systems, then can be when determining whether that dump power is shared to non-master B carrier waves
Quantity judged in advance, if the quantity of non-master B carrier waves is not reaching to default numerical value, can avoid follow-up sentencing
It is disconnected.
Step 204, if it is determined that carry out power between different systems communication system and share, adjust wherein one or more
The available horsepower of the communication system of standard.
Shared if it is determined that to carry out power between different systems communication system, then can be to wherein one or more
The available horsepower of the communication system of standard enters Mobile state adjustment.Specifically adjustment mode can have a variety of, and which part mode can
With the associated description with reference to subsequent embodiment.
Fig. 3 is the flow chart for the power sharing method that another embodiment of the present invention provides, as illustrated, including：
Step 301, the communication of at least one standard in the communication system for each standard for sharing same power amplifier
The power demand of system determines whether that power is carried out between different systems communication system to be shared.
The implementation of the step may be referred to the associated description in Fig. 1 or Fig. 2, and here is omitted.
Step 302, according to the sharable dump power of the communication system of the first standard, the communication system to the first standard
With the communication system configuration available horsepower of other one or more standards.
For example, the general power being currently configured of the communication system of the first standard first can be subtracted into sharable dump power
Available horsepower as the communication system for being allocated to the first standard afterwards；Then being currently configured in one or more other standards
On power level, sharable dump power is distributed to the communication system of other one or more standards according to default rule
System.
Specifically, sharable dump power distributes to the communication system of other one or more standards according to default rule
Uniting to be：If there is the communication system of other multiple standards, then the sharable dump power is temporally divided successively
The communication system of other the multiple standards of dispensing（For example, at 12, sharable dump power is distributed into UMTS and is total to
Enjoy, at 15, it is shared etc. that sharable dump power is distributed into LTE）；Or can be according to the logical of other multiple standards
The priority of letter system, by sharable dump power according to priority from high to low be sequentially assigned to multiple other standards
Communication system；Or sharable dump power is averagely allocated to the communication system of other multiple standards.Wherein, priority
It can be determined according to the performance of communication system, for example, the problem of communication system of certain standard easily produces underpower, then need
High priority is arranged to, preferentially to obtain shared power；Or priority can also determine according to the tendentiousness of operator,
For example, operator wishes the preferential normal operation for ensureing UMTS, then the system can be arranged to high priority；Or according to
The power demand of the communication system of these standards, power demand is bigger, and the priority of setting is higher.
Step 303, the sharable dump power of the communication system of the first standard is shared into other one or more systems
The communication system of formula.
For example, it is assumed that the communication system of the first standard is GSM, the communication system of other standards is UMTS, specifically,
Obtain the shared power of the UMTS available horsepowers before power is shared in UMTS available horsepowers=acquisition after shared power+agreement reception.
Wherein, the shared power for agreeing to receive is the part work(that UMTS agrees to receive from the sharable dump power of gsm system
Rate.Further, the HSDPA networks that the shared power received from GSM standards can be used under UMTS standards, the HSDPA networks
Using from the shared obtained power of GSM standards, because power is more, available modulation code is got in code division multiple access modulation mode
More, the content of carrying is bigger, therefore can be that community user improves downlink transmission data rate.
It is further to note that if the communication system for the first standard that the current preset cycle obtains when reaching is total to
The absolute value of the difference for the sharable dump power that the dump power enjoyed obtains when being reached with a upper predetermined period be less than or
Equal to the 3rd thresholding, the available horsepower of the communication system of each standard can be maintained constant, otherwise, according to the communication of the first standard
The sharable dump power of system is to the communication system of the first standard and the communication system configuration of other one or more standards
Available horsepower.So as to when the dump power of the communication system when the first standard changes greatly, to it is one or more other
The communication system of standard provides shared power, and when the dump power change of the communication system of the first standard is smaller, enter again
Row power is shared to have little significance, therefore can avoid continually carrying out the configuration of available horsepower, increases system burden.The above
Three thresholdings can also be set according to being actually needed.
Above examples provide communication system from the first standard to the communication system of other standards provide long when power
Secret sharing, after the communication system of communication system to other the one or more standards of the first standard, which carries out power, to be shared, the
Burst service is might have under the communication system of one standard, or, it is predicted that the available horsepower of the communication system of the first standard is not
Power demand of the communication system of the first standard in next predetermined period can be met, then the rollback of power can be carried out.
It will be described in detail below in case of there is burst service.
Illustrated below in case of GSM and UMTS shares a power amplifier, it is assumed that the communication system of the first standard
For GSM.
Shared it is assumed that providing power to UMTS from GSM, PA is configured with three GSM carrier frequency and a UMTS
Carrier frequency (is expressed as " G3U1 ") in Fig. 4, wherein, dotted line position represents that GSM carrier frequency reaches a power demand at the moment and is
20W burst service, remained after the power needed for the burst service is providing shared power beyond GSM standards for UMTS standards
During remaining available free power, current GSM residues available horsepower can not meet the needs of burst service, now need to return in time
The power for sharing to UMTS standards is received, and hacures represent carrier frequency uniformly to be cut on the time slot of burst service distribution in Fig. 4
Peak, to ensure that overall power requirement is no more than the PA of GSM side rated power, while to UMTS sides rollback power.It is therefore, of the invention
Another embodiment provides following power sharing method again.
Fig. 5 is the flow chart for the power sharing method that another embodiment of the present invention provides, as illustrated, being total to when carrying out power
It may further include after enjoying：
Step 401, when the communication system for detecting the first standard has burst service arrival and the communication system of first standard
The available horsepower of system can not meet the burst service reach after power demand when, the first standard after being reached according to burst service
The available horsepower of the communication system of the power demand of communication system and the first standard determines rollback power.
For example, it is assumed that the communication system of the first standard is UMTS, power demands of the UMTS in next predetermined period=
The current remaining work(of the when power demand+UMTS of HSDPA data is sent in UMTS current power demands+next predetermined period
Rate.
Step 402, the communication of the communication system and other one or more standards of the first standard is updated according to rollback power
The available horsepower of system.
Specifically, the communication system of the first standard before available horsepower=renewal of the communication system of the first standard after renewal
The available horsepower of system+rollback power.Complete renewal after, by power amplifier according to the available horsepower after each system update be into
Row power amplification.
By the present embodiment methods described, when the communication system traffic of the first standard is busy, Hui You can be dynamically wanted
The communication system of one standard shares to the shared power of the communication system of the second standard, therefore can further improve power and share
Flexibility, farthest avoid to caused by the service feature of the communication system of the first standard adverse effect.
It is further to note that because above-mentioned rollback power process has certain time delay, therefore returned completing power
PA overloads may occur before moving back, therefore before above-mentioned steps 402 are performed, can also further perform following steps：According to
The difference of the available horsepower of the communication system of the power demand of the communication system of first standard and the first standard cuts down the first standard
Communication system available horsepower.
For example, it is assumed that the communication system of the first standard is GSM, specifically, can be calculated according to equation below：GSM
Peak clipping power=GSM power demand-GSM available horsepowers.
Wherein, GSM peak clippings power refers to the power to be pruned from GSM available horsepowers.GSM power demands include：It is above-mentioned
Demand power before burst service arrival（The transmission power needed including pilot signal）And above-mentioned burst service demand
Power.
Then peak clipping processing is carried out to the traffic carrier configured under GSM according to the GSM peak clippings power calculated.Specifically cut
Peak processing can carry out uniform peak clipping according to the number of the traffic carrier configured under GSM to each traffic carrier.Each business carries
Ripple peak clipping power=GSM peak clippings power/gsm service carrier number.Wherein, traffic carrier refers to remove and led in BCCH channels for transmission
Carrier wave beyond frequency signal.
It should be noted that above is being illustrated in case of there is burst service, it is to be appreciated that when
Predicting the available horsepower of the communication system of the first standard can not meet the communication system of first standard next default
During power demand in the cycle, can also similar mode be used to handle, can be according in next predetermined period under this scene
Power demand and the available horsepower of communication system of the first standard determine rollback power.
Fig. 6 is the flow chart for the power sharing method that another embodiment of the present invention provides, as illustrated, this method includes：
Step 501, in units of the maximum power control cycle in the communication system of each standard, in the communication system of each standard
In each minimum power control cycle in system, the power demand sum for the communication system for sharing the same each standard of power amplifier is obtained,
If power demand sum is more than the rated power of power amplifier, shared it is determined that carrying out power between different systems communication system.
For example, it is assumed that the communication system of one of standard is GSM, the communication system of another standard is UMTS.Such as Fig. 7 institutes
Show, be GSM and UMTS power demand moment schematic diagram, the numeral of " 0 " " 1 " in figure ... " 7 " is represented in a TDMA frame
8 time slots numbering, can be by a UMTS slot length as illustrated, herein（Such as 2ms）It is interpreted as maximum power control week
Phase；And a GSM slot length is the minimum power control cycle.For example, in first 2ms of UMTS time slot, " 0 " number,
GSM and UMTS power demand sum is obtained in the GSM time slots of " 1 " number and " 2 " number, if the power demand got it
With the rated power more than power amplifier, it is determined that need the progress power between GSM and UMTS to share.
Step 502, the available horsepower of the communication system of wherein one or more standards is adjusted.
For example, it is assumed that the communication system of one of standard is GSM, the communication systems of other standards is UMTS, specific mistake
Journey can be as follows：
（1）If GSM current power demand is beyond GSM available horsepower, and UMTS current power demand does not have
Beyond UMTS available horsepower, then peak clipping processing is carried out to GSM, and GSM peak clippings power=GSM current power demands+UMTS works as
The rated power of preceding power demand-power amplifier.
Wherein, the peak clipping processing carried out to GSM refers to reduction average emitted power, and " GSM current power demands+UMTS works as
Preceding power demand " represents the total power demands of GSM and UMTS, using total power demand beyond the part of PA rated power as
GSM peak clipping power carries out peak clipping processing to GSM, to ensure UMTS power demand.
（2）If GSM current power demands without departing from GSM available horsepowers, and UMTS current power demands beyond
UMTS available horsepowers, then peak clipping processing is not done in GSM standards.
（3）If GSM current power demand is beyond GSM available horsepower, and UMTS current power demand also surpasses
UMTS available horsepower is gone out, then peak clipping processing has been carried out to GSM, and GSM peak clippings power=GSM current power demands-GSM can use
Power.
Due to GSM current power beyond the GSM available horsepower, therefore will exceed part be used as GSM peak clipping power
Peak clipping processing is carried out to GSM.
When the communication system of the above-mentioned each standard for sharing same power amplifier is GSM and UMTS, this example can also enter
One step comprises the following steps：
Step 503, if the power of GSM and UMTS complex RF signal beyond power amplifier rated power, it is right
UMTS carries out slicing processing.
For example, after carrying out peak clipping processing to GSM in step 502, GSM and UMTS complex RF signal still have
The rated power of power amplifier can be exceeded, therefore slicing processing is carried out to UMTS using this step, wherein, slicing processing refers to reduce peak
Compare.
Instantaneous power is realized by the power control cycle in communication system of the present embodiment methods described based on each standard
It is shared, shared so as to realize the power of dynamic flexible between the communication system of at least two standards.
Fig. 8 is the flow chart for the power sharing method that another embodiment of the present invention provides, as illustrated, this method includes：
Step 601, if sharing the communication system of high priority in the communication system of each standard of same power amplifier
Power demand exceedes default load thresholding, it is determined that power is carried out between different systems communication system and is shared.
Wherein, priority can determine according to the performance of communication system, for example, the communication system of certain standard easily produces
The problem of underpower, then need to be arranged to high priority, preferentially to obtain shared power；Or priority can also basis
The tendentiousness of operator determines, for example, operator wishes the preferential normal operation for ensureing UMTS, then can be arranged to the system
High priority；Or the power demand of the communication system according to these standards, power demand is bigger, and the priority of setting is higher.
Certainly the priority of communication system can also be determined in other way, and the present embodiment is not limited this.
Step 602, the available horsepower of the communication system of low priority is reduced.
The present embodiment methods described is when the communication for sharing high priority in the communication system of each standard of same power amplifier
The power demand of system exceedes default load thresholding, it is determined that power is carried out between different systems communication system and is shared, and is dropped
The available horsepower of the communication system of low low priority, so as to advantageously ensure that the communication system of high priority has enough can use
Power.
