In embodiments of the present invention, this term of load capacity represents the occupation condition in community.One skilled in the art will appreciate that negative
Carrying capacity can be reflected by different indexs according to actual needs, such as, can be reflected by portfolio, these indexs of number of users,
Therefore can correspondingly select judgment criterion to determine the transmitting changed power requirement of capacity station community CELL2.Launch changed power
Require may is that and improve launching power and needing the transmission power level improved, the transmitting power reducing CELL2 and permit of CELL2
The transmitting power being permitted transmission power level and the holding CELL2 reduced is constant.About specifically how determining that transmitting changed power is wanted
Ask, specifically describe hereinafter in connection with Fig. 4.
Step 320, require to utilize Business Processing mode to user according to the transmitting changed power of capacity station community CELL2 and/or
Business processes.Here, the processing mode used can determine according to actual needs, include but not limited to: to Gao You
First level Business Processing, low priority traffice processed and double small district (DC) user is processed, its purpose is to drop as far as possible
Low systematic function and Consumer's Experience are affected.About specifically how customer service being processed, have hereinafter in connection with Fig. 5
Body describes.
Step 330, launching at the transmitting power that changed power requires capacity station community according to capacity station community CELL2
Reason.
Preferably, above-mentioned power deratng method can periodically carry out, and such as, can be provided with timing in a base station for this
Device, periodically to trigger said method.For example, it is possible to every 100ms performs the most above-mentioned power deratng method.
If it addition, use load capacity based on QoS of survice to determine the transmitting changed power requirement of CELL2 in the step 310,
The most preferably, based on QoS of survice, the user in capacity station community CELL2 was first processed before step 310.Specifically
For, process according to the diversity of user and the priority of business.For high-priority users and dedicated channel (DCH)
User, still ensures its business, i.e. remains unchanged, and for low priority traffice, reduces speed and only ensure that it is basic
Bit rate (GBR), and do not guarantee that real time rate.By reducing low priority traffice in advance based on QoS of survice
Speed, thus reduce load capacity L2 in CELL2 so that in step 310 subsequently, load capacity based on QoS is come
Determine when the transmitting changed power of CELL2 requires there is bigger being likely to be obtained and reduce the requirement launching power of CELL2, from
And be conducive to saving the power consumption of base station.
In the method for the present embodiment, adjust the transmitting power of capacity station community according to the load capacity of community, thus solve existing

Fig. 4 shows that load capacity based on covering community, station and capacity station community according to embodiments of the present invention is according to predetermined
Judgment criterion determine capacity station community launch the flow chart that requires of changed power.As seen from Figure 4, true according to cell load amount
The transmitting changed power of constant volume station community CELL2 requires to specifically include:
Step 410, acquisition cover first load capacity L1 of station community CELL1, by the first load capacity L1 and the first threshold value
Th1 compares.As described in embodiment above, load capacity can be reflected by different indexs according to actual needs,
Such as can be reflected by portfolio, these indexs of number of users, therefore can correspondingly select the first used threshold value
Th1.Such as, in the case of carrying out reflected load amount by portfolio, it is assumed that the total business volume that CELL1 can carry is A, set
Th1 is A*80%.Or, in the case of carrying out reflected load amount by number of users, it is assumed that the number of users that CELL1 can accommodate is B,
Set Th1 as B*80%.The most here 80% is merely possible to example and is given, and those skilled in the art can be according to reality
Situation specifically sets.First threshold T h1 is relevant with the transmitting power P 1 covering station community CELL1.Such as, covering is worked as
The transmitting power P 1 of community of standing is the biggest, then total business volume A that CELL1 can carry is the biggest, or open ended number of users B
The most, etc..
Step 420, when the first load capacity L1 more than the first threshold T h1 time, determine capacity station community CELL2 need improve
Launch power, and correspondingly determine the transmission power level needing to improve.As L1 ＞ Th1, show to cover station community CELL1's
Load capacity is the biggest, it is therefore desirable to improve the transmitting power of capacity station community CELL2, in order to meet the capacity requirement of business.When
Determine when capacity station community CELL2 needs to improve transmitting power, the transmitting power of capacity station community CELL2 is improved to institute
Need performance number.For this transmitting power of capacity station community CELL2 can be divided into N number of grade (according to N it needs to be determined that
Natural number), according to hardware limitation such as power amplifiers, it is assumed that the maximum transmission power of capacity station community CELL2 is P2MAX, then power divides
After Ji, it is launched power and is designated as P respectively2,0, P2,1, P2,2..., P2, N(wherein P2,0=P2MAX, P2, N＞ 0).Here, each grade it
Between difference power can be as desired to determine, and it is identical to be not necessarily to Seeking Truth.When improving transmitting power, merit will be launched
Rate improves according to grade.Do not require that it is to improve step by step the most yet, but can according to practical situation determine raising one or
Several grades of person, in order to meet the capacity requirement of business.Owing to there is the situation of burst service, therefore improving transmitting merit
Preferably directly improve launching power to the maximum P being capable of during rate2MAX, can not meet avoiding the occurrence of power system capacity
The situation of business demand.
Step 430, when the first load capacity L1 is below the first threshold T h1, obtain capacity station community CELL2 second
Load capacity L2, compares the second load capacity L2 and the second threshold T h2.Owing to when L1 is at below Th1, showing to cover
The load capacity of Gai Zhan community CELL1 is little, whether therefore can determine whether the transmitting power of capacity station community CELL2
Need to adjust.As described above, it is also possible to correspondingly select the second used threshold value according to the index of reflected load amount
Th2.Such as, in the case of carrying out reflected load amount by portfolio, it is assumed that the total business volume that CELL2 can carry is B, set
Th2 is B*20%.Or, in the case of carrying out reflected load amount by number of users, it is assumed that the number of users that CELL2 can accommodate is B,
Set Th2 as B*20%.Here 20% is also merely possible to example and is given, and those skilled in the art can be according to actual feelings
Condition specifically sets.Second threshold T h2 is the most relevant with the transmitting power P 2 of capacity station community CELL2.
Step 440, when the second load capacity L2 less than the second threshold T h2 time, determine capacity station community CELL2 allow fall
Low transmitting power, and correspondingly determine the transmission power level allowing to reduce.As L2 ＜ Th2, capacity station community CELL2 is described
Load capacity less, therefore can reduce the transmitting power of CELL2 to save power consumption.To this end, can determine whether to hold
Whether second load capacity L2 of Liang Zhan community CELL2 is less than the 3rd threshold T h3, if the second load capacity L2 is less than the
Three threshold T h3, it is determined that allow to turn off the transmitting power of capacity station community, otherwise determine that permission will be launched power and be reduced
Predetermined grade.Here, the 3rd threshold T h3 is value set in advance.When the second load capacity is less than the 3rd thresholding
During value Th3, illustrate that the business load amount of this capacity station community is the least, carrier wave shutoff can be carried out.Turn off carrier wave namely pass
Disconnected community, including the pilot frequency information turned off in this district common channel, broadcast message etc..Carrier wave turn-off technique is existing skill
Art, is not detailed herein.If the second load capacity L2 is more than the 3rd threshold T h3, it is impossible to carry out carrier wave pass
Disconnected, in order to avoid the impact on user as far as possible, determine and use, when reducing and launching power, the method gradually reduced.Here,
The grade classification being the most set can be used, it would however also be possible to employ different grade classification.Each grade it
Between difference power can be as desired to determine, and it is identical to be not necessarily to Seeking Truth.When reducing transmitting power, merit will be launched
Rate reduces according to grade.Do not require that it is to reduce step by step the most yet, but can according to practical situation determine reduction by one or
Several grades of person.
Step 450, when the second load capacity L2 is more than the second threshold T h2, show to cover station community CELL1 and appearance
Liang Zhan community CELL2, all in suitable duty, is i.e. in stable duty, it is thus determined that capacity station community CELL2
Keep launching power constant.
Visible, according in the scheme of the present embodiment, utilize corresponding based on the load capacity covering community, station and capacity station community
Threshold value judge, such that it is able to exactly the duty of community is classified, in order to further control capability
Stand the transmitting power of community.
Fig. 5 show according to embodiments of the present invention, require to utilize industry according to the transmitting changed power of capacity station community CELL2
The flow chart that user and/or business are processed by business processing mode.From figure 5 it can be seen that to user and/or business
Reason comprises the following steps.
Step 510, the transmitting changed power requirement of acquisition capacity station community CELL2.Here, can be from combining described by Fig. 4
Method in obtain above-mentioned transmitting changed power requirement.
Step 520, when determine capacity station community CELL2 allow reduce launch power, and correspondingly determine allow reduce
During transmission power level, the transmission power level reduced according to this permission is revised the community of the graphical user in capacity station community and is cut
Change threshold value so that the user being in connection status in graphical user switches to cover in the community stood, and is in idle shape
State user, after power reduces, reselects to cover community, station automatically.In embodiments of the present invention, graphical user is meant that,
Originally in the coverage of capacity station community CELL2, but do not locate after reducing the transmitting power of capacity station community
User in its coverage.Therefore, it can according to allowing the transmission power level reduced to determine graphical user and to it
Community handoff threshold value is modified.For the user of switching, for example, it is possible to come by radio network controller (RNC)
The community handoff threshold value of amendment user.When reducing due to the transmitting power of CELL2, CELL2 coverage reduces accordingly,
Belong to the graphical user in the coverage of CELL2 originally may not continue to be attached in CELL2, therefore by revising this
The handoff threshold value of a little graphical user, so that these users think that the signal intensity of CELL2 can not meet communicating requirement,
Thus Pre-handoff is to covering in the community CELL1 of station, thus avoid the follow-up adjustment impact launching power on CELL2
Graphical user.
Step 530, other users in addition to graphical user in capacity station community CELL2 are classified, and according to
The classification at family carries out respective handling.For example, it is possible to switch to high-priority service cover in the community CELL1 of station, thus
Ensure the service of high-priority service；Low priority traffice can be reduced speed and ensure its basic bit speed, thus
After reducing the transmitting power of capacity station community CELL2, it is reduced as far as the capacity to capacity station community CELL2
Impact；And so that double small district (DC) user select cover station community CELL1 as its main plot, due to DC
User uses Liang Ge community simultaneously, by using covering station community CELL1 as main plot, equally make as auxiliary little
The transmitting power of capacity station community CELL2 in district reduces the impact for DC user and is reduced to minimum.
If it is determined that capacity station community CELL2 transmitting power need increase or keep constant, then without to user and/
Or business carries out above-mentioned process.
Visible, according in the scheme of the present embodiment, before changing the transmitting power of capacity station community CELL2 to user and/
Or business is processed, so that the impact for systematic function and Consumer's Experience is less.

Liang Zhan community CELL2 allows to reduce when launching power, it is possible to use voltage adjustment of the power amplifier technology, according to the output that power amplifier is actual
Numerical value, dynamically adjusts the running voltage of the power amplifier of base station, when capacity station community CELL2 needs to increase power, makes diligent
Put voltage-regulating technique so that the performance number improved as required adjusts the running voltage of base station.For example, it is possible to notified base by RNC
Stand in when power is launched in reduction and use voltage adjustment of the power amplifier technology.
Visible, in power adjustment procedure, improve to maximum by power directly will be launched when improving and launching power, and
Reduce and carry out according to predetermined grade when launching power, it is to avoid power system capacity can not meet the situation of business demand, and
Can avoid reducing the power impact on user.It addition, by using voltage adjustment of the power amplifier technology, even if at the transmitting power of CELL2
When being reduced to reduced levels, the work efficiency of power amplifier also will not be the lowest so that power amplifier is fully used, thus saves power
Resource.
