Embodiments of the invention are described below in detail, the example of the embodiment is shown in the drawings, wherein from beginning to end
Same or similar label represents same or similar element or the element with same or like function.Below with reference to attached
The embodiment of figure description is exemplary, is only used for explaining the present invention, and is not considered as limiting the invention.
The embodiments of the invention provide a kind of method of the cooperation of the inter-cell power under LTE scenes, referring to Fig. 1, being this
The flow chart of inter-cell power collaboration method under the LTE scenes of inventive embodiments, as illustrated, the method comprising the steps of S101
To S103.
Step S101, the user according to each cell access number or customize the priority that scene determines each cell.It is described
Priority includes one kind in the first priority, the second priority, third priority.Third priority is lowest priority, the
One priority is limit priority, and the second priority is normal priority.The transmission power of normal priority cell is initially to match somebody with somebody
The transmission power put.The priority of cell can be determined according to one in following two methods.
First, the number of users that base station side is currently accessed according to cell adaptively confirms the priority of cell, i.e.
When the user of cell, which accesses number, is higher than first threshold, the cell is defined as the first priority cell；
When the user of cell, which accesses number, to be between first threshold and Second Threshold, the cell is defined as the second priority
Cell；
When the user of cell, which accesses number, is less than Second Threshold, the cell is defined as third priority cell.
The first threshold that each cell is set is more than Second Threshold, according to actual state, the first threshold of each cell setting
Value or Second Threshold can be with identical, can also be different.
Second, when configuring cell on OMMB, the customization scene according to cell directly can determine the priority of cell
For one kind in the first priority, the second priority, third priority.The customization scene of cell is for example moved including special screne
Meeting, concert etc., and general scene, it is defined as the first priority for the native region priority of special screne, general scene
Native region priority can be identified as the second priority or third priority.The cell of priority is not determined when configuring cell on OMMB

First priority cell, the transmission power of corresponding distribution adds for the transmission power of cell initial configuration puts down
Equal dump power, the average residual power subtract second priority cell and the 3rd excellent for the rated power of RRU veneers
It is small according to the first priority after the transmission power of first level cell distribution and the transmission power of the first priority cell initial configuration
The number in area carries out average value.
Step S103, according to the transmission power of each cell distribution, the scheduling of transmission power is carried out to each cell.So that
User in cell perceives the change of transmission power, so as to embodied on data throughout.The transmitting work(of each cell
Rate can be from the power for strengthening the reference power of cell level, the radiation beam intensity for strengthening cell, UE user class, these three
Dimension is scheduled RSRP (Reference Signal Receiving Power, the reference for being finally reached enhancing user and receiving
Signal reception power), (Signal to Interference plus Noise Ratio, signal adds with interference makes an uproar lifting SINR
Acoustic ratio), so as to improve data throughout.The scheduling mode of three dimensions is：
The reference power of cell is adjusted according to the transmission power of distribution；
The angle of radiation of cell is adjusted according to the transmission power of distribution；
Each user in cell is adjusted according to the transmission power of distribution and receives power.
The present embodiment by determining each native region priority of work at present in base station in real time, according to priority and transmitting
The specified transmission power that the corresponding relation of power distribution supports RRU veneers distributes to each cell, and by each small differentiation
It is scheduled with obtained transmission power, realizing expires use of the specified transmission power without waste that RRU veneers are supported, and can
To realize each cell of distributing to of dynamic optimization, improvement intercell load is unbalanced, reaches the effect of lifting Consumer's Experience.
In another embodiment of the invention, step S104 includes：Judge the current transmission power of each cell whether etc.
In the transmission power of each cell distribution；When transmission power of the current transmission power of cell not equal to cell distribution,
According to the transmission power of cell distribution, the transmission power of the cell is scheduled.

It is not defined as the first priority cell and third priority cell.
Step 303, distributed according to default priority and transmission power distribution corresponding relation and adjust Cell1 and Cell2
Transmission power.The transmission power of Cell2 distribution suppresses configuration parameter for the power of cell on OMMB and matches somebody with somebody the initial of the cell
Real power P2 ' after putting transmission power and reducing, such as when power suppresses configuration parameter and is equal to 3Db, P2 ' is approximately equal to the one of P2
Half；The transmission power of Cell1 distribution adds average residual power, the average residual work(for the transmission power of Cell1 initial configurations
Rate for RRU veneers rated power subtract Cell2 distribution transmission power and Cell1 cell initials configuration transmission power after by
Average value is carried out according to the number of the first priority cell, specifically, the calculation formula of the transmission power of Cell1 distribution is：P1+
(P0-P2 '-P1)/1, wherein denominator 1 represent the number of the first priority cell, and in the present embodiment, the first priority cell only has
1.
The present embodiment is custom made with special screne such as athletic meeting, concert mainly for some cells, by OMMB
During upper configuration cell, these cells are directly determined into the first priority, the priority of other cells be defined as the second priority or
Third priority, and according to default priority and the transmission power of transmission power distribution corresponding relation distribution cell.
It should be noted that configure cell on OMMB, and when determining the priority of cell, it is not absolutely required to all
Cell determine priority, when configuring cell on OMMB, do not determine the cell of priority, then by the number of users in cell come
Determine the priority of cell.
