Rate resource can be shared, and maximally utilize radio frequency resource to reach, and reduce network investment and promote the purpose of user experience.
The power resource of cell demand in each sector is assessed in the embodiment of the present invention, then judges that sector is corresponding
The available power resource of radio frequency unit whether can satisfy the demand of cell in sector, that is, whether there is sector to be adjusted,
Sector to be adjusted if it exists will be determined cell to be adjusted from sector to be adjusted, be adjusted by power distribution apparatus
In the target sector that can satisfy cell demand to other, in this way, the embodiment of the present invention can estimate the power of each cell in real time
The resource amount of renewing, and measure the power resource amount that can be exported with radio frequency unit according to its demand and the cell under each sector is fitted
When adjust, without manually participate in and stop the communication equipments such as base station can solve radio frequency unit power resource it is nervous
The problem of, avoid power resource in some sectors nervous, and the situation of other Sector Power resource free time, it realizes simply, no
It will affect the use of user's regular traffic.
Further embodiment of this invention provides a kind of method of radio frequency unit power distribution, as shown in figure 3, the method packet
It includes:
201, it is defeated to determine that the corresponding relationship of each radio frequency unit and each sector, each radio frequency unit are able to for baseband processing unit
The usage degree of the total amount of power resource and each radio frequency unit out.
202, baseband processing unit determines priority according to the usage degree of each radio frequency unit, and according to priority by height to
It is low to be ranked up.
Wherein, the higher usage degree for indicating radio frequency unit of priority is lower.
203, baseband processing unit obtain the number of users of cell in current each sector, in each sector the portfolio of cell and
The wireless communication status of each sector.
204, baseband processing unit estimates each cell in each sector according to number of users, portfolio and wireless communication status
The demand of the demand of power resource and each Sector Power resource.
205, baseband processing unit judges that there are sectors to be adjusted for each sector, if there are sector to be adjusted in each sector,
Execute step 206；If sector to be adjusted is not present in each sector, 203 are thened follow the steps.
Wherein, sector to be adjusted indicates that the demand that power resource is estimated in sector to be adjusted is corresponding greater than sector to be adjusted
The total amount of radio frequency unit output power resource.When there are when sector to be adjusted, indicate some sectors to power resource meeting for each sector
There is very big demand, and the power resource that corresponding radio frequency unit can export is not able to satisfy its demand, these fans
Area will emergent power resource anxiety situation.
206, baseband processing unit determines cell to be adjusted in the cell of sector to be adjusted.
Wherein, cell to be adjusted is that the cell of other sectors is adjusted to from sector to be adjusted, and sector to be adjusted will be wait adjust
Whole cell is adjusted to other sectors, and the power resource demand of estimating of remaining cell will be corresponding less than or equal to sector to be adjusted
The power resource amount that radio frequency unit can export.
207, baseband processing unit is according to putting in order, according to corresponding relationship, each radio frequency unit output power resource it is total
Amount, each sector estimates the demand of power resource and the demand of cell prediction power resource to be adjusted successively judges whether there is
Target sector, target sector, thens follow the steps 208 if it exists；Target sector if it does not exist thens follow the steps 201.
Wherein, the target sector corresponds to the power resource that radio frequency unit has idle frequency point and the idle frequency point offer
Not less than the demand of the cell prediction power resource to be adjusted.
It should be noted that radio frequency unit priority is higher, indicate that its power resource usage degree is lower, i.e., it is idle
Power resource degree is higher, then when adjusting cell to be adjusted, the high sector of the idle power resource degree of preferential judgement, from
And target sector can be determined as soon as possible, reduce the process of data processing.
208, judge whether the idle frequency point of target sector is in completely idle state, if idle frequency point is in completely idle
When state, step 211 is executed；If idle frequency point is not at completely idle state, step 209 is executed.
209, the demand for estimating power resource of the currently used idle frequency point cell is determined.
210, judge the demand for estimating power resource and residue cell prediction power of currently used idle frequency point cell
Whether the sum of demand of resource, which is greater than sector to be adjusted, corresponds to the total amount of radio frequency unit output power resource, if being not more than,
Execute step 211；If more than thening follow the steps 201.
Wherein, remaining cell is sector to be adjusted except remaining cell after cell to be adjusted.
211, baseband processing unit sends adjustment instruction to the power distribution apparatus.
Wherein, the adjustment instruction includes the corresponding relationship of the cell to be adjusted and the target sector, and expression will be to
Adjustment cell is adjusted to target sector.When the need for estimating power resource for determining currently used idle frequency point cell in step 210
The sum of the amount of asking and demand of remaining cell prediction power resource are no more than the corresponding radio frequency unit output power money in sector to be adjusted
When the total amount in source, adjustment instruction, which further includes that the currently used idle frequency point cell is corresponding with the sector to be adjusted, is closed
System, expression not only adjust cell to be adjusted to target sector, it is also necessary to adjust currently used idle frequency point cell to wait adjust
Whole sector.
The power resource of cell demand in each sector is assessed in the embodiment of the present invention, then judges that sector is corresponding
The available power resource of radio frequency unit whether can satisfy the demand of cell in sector, that is, whether there is sector to be adjusted,
Sector to be adjusted if it exists will be determined cell to be adjusted from sector to be adjusted, be adjusted by power distribution apparatus
In the target sector that can satisfy cell demand to other, in this way, the embodiment of the present invention can estimate the power of each cell in real time
The resource amount of renewing, and measure the power resource amount that can be exported with radio frequency unit according to its demand and the cell under each sector is fitted
When adjust, without manually participate in and stop the communication equipments such as base station can solve radio frequency unit power resource it is nervous
The problem of, avoid power resource in some sectors nervous, and the situation of other Sector Power resource free time, it realizes simply, no
It will affect the use of user's regular traffic.
