Four, edge section, wherein center of housing estate section are that signal quality is adjudicated more than or equal to center of housing estate in serving cell where user
Corresponding position when thresholding；Secondary center of housing estate section is that signal quality is less than center of housing estate decision gate in serving cell where user
It limits and is more than or equal to corresponding position when secondary center of housing estate decision threshold；Cell switching band section is serving cell where user
Interior signal quality is less than time center of housing estate decision threshold and position corresponding more than or equal to when switching with decision threshold；Cell side
Edge section is that signal quality is less than corresponding position when switching band decision threshold in serving cell where user；
Step S204：Different power contorl parameters are arranged to different position sections in base station：The channel compensation factor
With minimum target Signal to Interference plus Noise Ratio；
The channel compensation factor and minimum target Signal to Interference plus Noise Ratio in the step S204 are matched according to four positions section
It sets, following criterion may be used in the principle of configuration：Four center of housing estate, secondary center of housing estate, cell switching band and cell edge areas
Between the channel compensation factor be gradually reduced, and the minimum target Signal to Interference plus Noise Ratio in four sections is gradually reduced, and ensures each area
Between the maximum target Signal to Interference plus Noise Ratio that calculates be less than the minimum target Signal to Interference plus Noise Ratio close to center of housing estate section, for example, secondary small
The maximum target Signal to Interference plus Noise Ratio of district center should be smaller than the minimum target Signal to Interference plus Noise Ratio of center of housing estate, wherein maximum target Signal to Interference plus Noise Ratio
According to the channel compensation factor and minimum target Signal to Interference plus Noise Ratio, it is calculated by Signal to Interference plus Noise Ratio calculation formula.
This concrete application example realizes that dynamic position section is drawn by the user mobile information in periodic harvest cell
Point, the target Signal to Interference plus Noise Ratio meter that user's physical location is mapped to corresponding section will not be influenced because of the adjustment of the coverage area of base station
It calculates, there is stronger operability.In addition, different path loss is arranged to different position sections in this concrete application example
Compensation factor and minimum target Signal to Interference plus Noise Ratio ensure that the user for switching band and cell edge in cell will not be to subcenter
Cell and Cell Center User interfere, and ensure that user's lowest performance of cell switching band and cell edge is wanted
It asks, under the premise of avoiding interference, improves cell entire throughput and handover success rate.
Step S205：Base station obtains the location information of user；
Location information in the step S205 refers mainly to the path damage of user distance service base station in this serving cell
Consumption can be estimated by RSRP that UE measurements report or PHR；
Step S206：Corresponding Signal to Interference plus Noise Ratio (SINR) is searched according to customer position information and adjusts section in base station；
The method of lookup in the step S206 is mapped to according to the location information of user in center of housing estate, secondary cell
One of section in four heart, cell switching band and cell edge sections, and the target letter for obtaining user place section is dry
Make an uproar than calculation formula；
Step S207, base station calculate the Signal to Interference plus Noise Ratio needed for corresponding position, update the target Signal to Interference plus Noise Ratio of user
(SINRtar)；
This concrete application example obtains the location information of user by the mobile message that user's measurement reports, and searches corresponding
Signal to Interference plus Noise Ratio calculation formula, the target Signal to Interference plus Noise Ratio of this user is calculated according to Signal to Interference plus Noise Ratio calculation formula.This is specifically answered
With the Signal to Interference plus Noise Ratio calculation formula of location information of the example based on user and different sections, ensure that in cell switch band and
The user of cell edge will not interfere secondary middle cell heart user and center of housing estate, while also ensure that cell switches band
And user's minimum performance requirement of cell edge improves cell entire throughput and switching under the premise of avoiding interference
Success rate.

Section；
Section and its corresponding channel compensation factor are adjusted according to the Signal to Interference plus Noise Ratio and minimum target Signal to Interference plus Noise Ratio calculates use
The Signal to Interference plus Noise Ratio is updated to the target Signal to Interference plus Noise Ratio of user by the Signal to Interference plus Noise Ratio needed for the corresponding position of family；The threshold module
Execute the user location decision threshold that statistics and average treatment are carried out to the mobile message, obtain needed for power control
Process is further used for：
Statistical weight is carried out averagely to the mobile message or statistics arithmetic average is handled, obtains cell switching band decision gate
Limit；
Switch band decision threshold according to cell and time center of housing estate decision threshold and center of housing estate decision gate are obtained by calculation formula
Limit；Wherein, calculation formula is A=B+ Δs1=C+2* Δs1, the A expressions center of housing estate decision threshold, the B expressions secondary cell
Center decision threshold, C indicate the cell switching band decision threshold, Δ1Indicate the signal quality difference of setting.
5. base station upstream power control system according to claim 4, which is characterized in that described in the division module executes
According to user location decision threshold, cell is marked off into different Signal to Interference plus Noise Ratio adjustment section processes and is further used for：
According to user location decision threshold, it is not less than the center of housing estate decision gate according to the signal quality in center of housing estate section
The signal quality of limit, secondary center of housing estate section is adjudicated not less than the secondary center of housing estate decision threshold and less than the center of housing estate
The signal quality of thresholding, cell impulsive switches band decision threshold not less than the cell and sentences less than the secondary center of housing estate
Certainly thresholding, the signal quality in cell edge section are less than cell switching band decision threshold and are divided into four Signal to Interference plus Noise Ratio adjustment
Section.
6. base station upstream power control system according to claim 5, which is characterized in that described in the setup module executes
During to the different Signal to Interference plus Noise Ratio adjustment section, the corresponding channel compensation factor and minimum target Signal to Interference plus Noise Ratio are set, if
The mode set is further used for：
According to the center of housing estate section, secondary center of housing estate section, cell impulsive, cell edge section channel compensation because
Son and minimum target Signal to Interference plus Noise Ratio successively decrease successively, and the section minimum target in two neighboring section close to center of housing estate believes dry make an uproar
Than more than the section maximum target Signal to Interference plus Noise Ratio close to cell edge.
