Description
Technical field
The present invention relates to a kind of communication technical field, more particularly to a kind of power regulating method, device, equipment and computer
Readable storage medium storing program for executing.

Under being oriented to using data service as the optimization of unique business, the network optimization is configured based on data service, and these are set simultaneously
The perception demand of not exclusively suitable speech business.For example：For the power programming of base station, current TD-LTE network powers are set
Mainly consider descending covering gain, base station transmitting power sets higher, and descending coverage is bigger, the sense that user covers to signal
Know better.But, the transmission power of base station sets excessive, and MPS process edge can be caused up limited, the voice of user is influenceed
Speech quality, specifically：
As shown in figure 1, when station spacing is excessive between base station 11 and base station 12, the He of descending coverage 101 of base station 11
There can be weak overlay area 103 between the descending coverage 102 of base station 12.Under such a scene, lifting base station 11 and base station
12 transmission power, the problem of weak covering can be improved to a certain extent.
As illustrated in fig. 2, it is assumed that the transmission power of lifting base station 11 and base station 12, then weak overlay area 103 hair to be lifted
The descending coverage 201 of base station 11 and the descending coverage 202 of base station 12 after lifting transmission power after power is penetrated to be covered,
This will lift the perception that user covers to signal in weak overlay area 103 to a certain extent.
But, for practical business use, base station power set conference to cause MPS process edge up limited, its
Actual performance is that descending covering is good, and user equipment (User Equipment, UE) transmission power reaches maximum still not
The transmission demand of uplink business data can be met, in such cases, the influence journey that speech business and data service are perceived to user
Degree is different.
As shown in figure 3, when the transmission power of base station 30 sets excessive, it is up that its descending coverage 301 will be greater than its
Range of receiving 302, now, if user equipment 31 is in cell edge (position shown in Fig. 3), at user equipment 31
In in the descending coverage of base station 30, but not in the range of the uplink receiving of base station 30, for data service, it can cause
The increase of up BLER(block error rate) (Block Error Ratio, BLER), data packet retransmission increased frequency, transfer delay increase, to
It is exactly that speed of surfing the Internet is deteriorated that what family was perceived, which directly affects, opens webpage slowly, extension etc. during uploading pictures, but data service is substantially
Still it can use；And VoLTE is symmetrical service, under normal circumstances, VoLTE upstream data packet loss is under
Row data packetloss, because upstream data packet loss problem is very big to VoLTE user's sensation influence, experiment shows, when upstream data is lost
When bag rate is more than 5%, voice quality will deteriorate into the unacceptable degree of human ear, therefore, and up-link is limited directly to be led
The high packet loss of upstream data is caused, so as to cause poor voice call quality, single-pass or even call drop, has serious to the experience of user
Negative effect.
In summary, base station can be made when solving weak covering problem by increasing base station transmitting power in the prior art
Descending coverage is more than uplink receiving scope, so as to cause the user equipment uplink in cell edge to be limited, seriously
Influence the voice call quality of user.

In the embodiment of the present invention, when it is determined that the descending coverage of base station is more than the uplink receiving scope of base station, then may be used
It is limited with the up-link for determining cell where causing base station because the power setting of base station is improper, therefore needs to adjust the hair of base station
Power is penetrated, so that the up-downgoing balance of cell where base station.
Step S402, the transmission power surplus that reports of intra-cell users equipment where obtaining base station and user equipment to report
Reference Signal Received Power RSRP.
The transmission power surplus being previously mentioned in the embodiment of the present invention refers to the maximum transmission power of user equipment permission and worked as
It is preceding assess obtained Physical Uplink Shared Channel (Physical Uplink Shared Channel, PUSCH) transimission power it
Between difference, what it was represented is the work(that user equipment can be used except when outside transimission power used in preceding PUSCH transmission
Rate.Its span is -23 decibels of (db)~40 decibel (db), and user equipment passes through index when reporting transmission power surplus
Mode report, corresponding index is 0-63, wherein, 0 corresponding transmission power surplus of index be more than or equal to -23db and
Less than -22db, 1 corresponding transmission power surplus of index is more than or equal to -22db and less than -21db, by that analogy, index
63 corresponding transmission power surpluses are more than or equal to 40db.
When it is implemented, the measurement report that transmission power surplus and RSRP can periodically be reported from user equipment
Obtained in (Measurement Report, MR), here is omitted.
Step S403, it is determined that the user equipment accounting that transmission power surplus is located in pre-set interval is less than the first default ratio
Example threshold value, and RSRP be more than the first predetermined power threshold value user equipment accounting be more than the second preset ratio threshold value under conditions of,
Stop the transmission power of regulation base station.
In the embodiment of the present invention, it is determined that transmission power surplus, which is located at the user equipment accounting in pre-set interval, is less than first
Preset ratio threshold value, and RSRP be more than the first predetermined power threshold value user equipment accounting be more than the second preset ratio threshold value when,
The up-link of cell and descending covering where base station can be determined are satisfied by requiring, namely the up-downgoing of cell where base station is put down
Weighing apparatus, then stop the transmission power of regulation base station.
Wherein, transmission power surplus is located at the user equipment accounting in pre-set interval, refers to that transmission power surplus is located at pre-
If the ratio of the number of user equipment and total number of user equipment in interval；The user that RSRP is more than the first predetermined power threshold value sets
Standby accounting, refers to that RSRP is more than the number of user equipment of the first predetermined power threshold value and the ratio of total number of user equipment.It is default
Interval, the first predetermined power threshold value, the first preset ratio threshold value and the second preset ratio threshold value can be carried out based on experience value
Setting, for example：Pre-set interval is [0,10], and the value of the first predetermined power threshold value is -110db, the first preset ratio threshold value
Value is 10%, and the value of the second preset ratio threshold value is 90%.
In the embodiment of the present invention, when it is determined that the descending coverage of base station is more than the uplink receiving scope of base station, namely
It is determined that the up-link of the user equipment in cell edge where base station is by limited time, by adjusting the transmission power of base station, adjust
The descending coverage of base station is saved, and obtains transmission power surplus and user equipment that base station place intra-cell users equipment is reported
The RSRP reported, it is determined that transmission power surplus, which is located at the user equipment accounting in pre-set interval, is less than the first preset ratio threshold
Value, and RSRP is more than the user equipment accounting of the first predetermined power threshold value more than under conditions of the second preset ratio threshold value, stops
The transmission power of base station is adjusted, the up-downgoing balance of cell is realized, so that while weak covering problem is solved, it is to avoid in small
The user equipment uplink of area edge is limited, and improves cell edge uplink quality, improves the call of edge customer equipment
Quality.
In practice, the power setting of base station cross conference cause Cell Edge User equipment up-link be limited, uplink interference
Caused quality of uplink signal is poor, also results in Cell Edge User equipment up-link and is limited, and uplink interference is usually
, it is necessary to manually investigate and eliminate interference as caused by interference source.Therefore, the embodiment of the present invention adjusts base station in implementation steps S401
Transmission power before, it is thus necessary to determine that the up-link of Cell Edge User equipment is limited be due to base station power setting it is excessive
It is caused, namely it needs to be determined that the descending coverage of base station is more than the uplink receiving scope of base station, and it is determined that base station
When descending coverage is more than uplink receiving scope, while it needs to be determined that the uplink interference in cell is not enough to cause cell edge
User equipment uplink is limited.
In consideration of it, the embodiment of the present invention is before the transmission power of regulation base station, in addition to：Obtain intra-cell users equipment
The transmission power surplus and the RSRP of user equipment to report reported；Based on transmission power surplus, RSRP and obtain in advance it is dry
Signal code power (Interference Signal Code Power, ISCP) is disturbed, determines that the descending coverage of base station is more than
The uplink receiving scope of base station.
Because transmission power surplus can be used for the uplink quality of determination cell, RSRP can be used for determining the descending of cell
Coverage rate, and ISCP can be used for the uplink interference level for determining cell, therefore, the embodiment of the present invention is set in acquisition intra-cell users
, can be based on transmission power surplus, RSRP and pre- after the RSRP of the standby transmission power surplus reported and user equipment to report
The ISCP first obtained, determines that the descending coverage of base station is more than the uplink receiving scope of base station.
When it is implemented, based on transmission power surplus, RSRP and the ISCP obtained in advance, determining the descending covering of base station
Scope is more than the uplink receiving scope of base station, including：It is determined that transmission power surplus, RSRP and ISCP meet condition simultaneously
First, condition two and during condition three, determines that the descending coverage of base station is more than the uplink receiving scope of base station：Condition one includes hair
Penetrate user equipment accounting of the power headroom in pre-set interval and be more than the first preset ratio threshold value；Condition two is more than including RSRP
The user equipment accounting of first predetermined power threshold value is more than the second preset ratio threshold value；Condition three includes ISCP and preset less than second
Power threshold.Wherein, the second predetermined power threshold value can be determined based on experience value, for example：The value of second predetermined power threshold value
For -90db.
Transmission power surplus is used for the uplink quality for determining cell, it is determined that transmission power surplus is located at pre-set interval
When interior user equipment accounting is more than the first preset ratio threshold value, determine that the uplink quality of cell has problem；RSRP is used
In calculating cell coverage, when it is determined that cell coverage is more than the first predetermined power threshold value, cell downlink coverage is determined
Meet and require；Now, cell uplink interference level is inquired about with reference to ISCP, if uplink interference level is less than the second predetermined power threshold
Value, then can exclude because uplink interference causes the limited situation of cell uplink, judge that cell is due to base station transmitting power
Set excessive caused up-link to be limited, namely determine that the descending coverage of base station is more than uplink receiving scope.
Reality is when adjusting the transmission power of base station, due to adjusting the transmission power of base station, is improving stingy up-link
While quality, the descending coverage of base station can be changed, therefore, in order that the base station up-downgoing balance after must adjusting, is being adjusted
, it is necessary to according to the change of uplink quality and descending coverage (or descending coverage rate) during the transmission power at integral basis station
Change be adjusted, with ensure adjustment after base station up-downgoing balance.
Specifically, the transmission power of base station is adjusted, including：Obtain the transmission power surplus that intra-cell users equipment is reported
With the RSRP of user equipment to report；It is big according to user equipment accounting of the transmission power surplus in pre-set interval, and RSRP
In the user equipment accounting of the first predetermined power threshold value, the transmission power of base station is adjusted.
When it is implemented, it is located at the user equipment accounting in pre-set interval according to transmission power surplus, and RSRP is more than
The user equipment accounting of first predetermined power threshold value, adjusts the transmission power of base station, including：It is determined that transmission power surplus is located at
User equipment accounting in pre-set interval is more than under conditions of the first preset ratio threshold value, reduces the transmission power of base station；True
Determine user equipment accounting of the transmission power surplus in pre-set interval and be less than the first preset ratio threshold value, and RSRP is more than first
The user equipment accounting of predetermined power threshold value is less than under conditions of the second preset ratio threshold value, increases the transmission power of base station.
It is determined that transmission power surplus, which is located at the user equipment accounting in pre-set interval, is more than the first preset ratio threshold value
Under the conditions of, show that the up-link of cell is limited, therefore need by reducing the transmission power of base station, covered to reduce the descending of base station
Lid scope, so as to avoid the up-link in Cell Edge User equipment from being limited.
Specifically when reducing the transmission power of base station, the transmitting work(of base station can be reduced with the first predetermined power regulated quantity
Rate.In order to ensure that the up-downgoing of base station is balanced, in some embodiments of the invention, with the reduction of the first predetermined power regulated quantity
During the transmission power of base station, the transmission power of base station can be repeatedly reduced, and after the transmission power of reduction base station every time, weight
The RSRP of the new transmission power surplus and user equipment for obtaining user equipment, and judge whether to need to continue to reduce the transmitting of base station
Power.Wherein, the first predetermined power regulated quantity can freely be set, in order to improve degree of regulation, can be by the first predetermined power
It is a little bit smaller that regulated quantity is set, for example：First predetermined power regulated quantity is 2db；, can also be by first in order to improve governing speed
Predetermined power regulated quantity set it is big a bit, for example：First predetermined power regulated quantity is 5db.
Certainly, it is necessary to illustrate, in order to take into account degree of regulation and governing speed, in other embodiments of the present invention,
When reducing the transmission power of base station, the size of the first predetermined power regulated quantity can also be changed with preset rules, for example：First
When reducing the transmission power of base station, the first predetermined power regulated quantity value is 5db, and the transmission power of base station is reduced after first
When, each reduction amount (namely first predetermined power regulated quantity) reduces 0.5db, namely second compared to previous reduction amount
During the transmission power of secondary reduction base station, the value of the first predetermined power regulated quantity is 4.5db, by that analogy.
It is determined that transmission power surplus be located at pre-set interval in user equipment accounting be less than the first preset ratio threshold value, and
RSRP is more than the user equipment accounting of the first predetermined power threshold value and is less than under conditions of the second preset ratio threshold value, shows cell
Up-link is normal, but the descending coverage rate of cell is not up to requirement, at this time, it may be necessary to increase the transmission power of base station, increases
The descending coverage of cell, makes the descending coverage rate of cell reach requirement, but also needs to ensure the up-link of cell simultaneously
Normally, balanced with the up-downgoing for reaching cell.
Specifically when increasing the transmission power of base station, the transmitting work(of base station can be increased with the second predetermined power regulated quantity
Rate, in order to ensure that the up-downgoing of base station is balanced, can increase the transmission power of base station several times, and in the hair of increase base station every time
Penetrate after power, reacquire the transmission power surplus of user equipment and the RSRP of user equipment, and judge whether to need to continue
Increase the transmission power of base station.Wherein, the second predetermined power regulated quantity can freely be set, more preferably, and setting second is pre-
If power adjusting amount is 0.5 times of the first predetermined power regulated quantity, such as：When the first predetermined power regulated quantity is 2db, set
Second predetermined power regulated quantity is 1db.
It should be noted that the embodiment of the present invention, it is determined that causing the descending covering of base station because base station power setting is excessive
When scope is more than uplink receiving scope, the detailed process of base station transmitting power is adjusted, including：
If it is determined that the user equipment accounting that transmission power surplus is located in pre-set interval is more than the first preset ratio threshold value, then
Reduce the transmission power of base station；Preset if it is determined that the user equipment accounting that transmission power surplus is located in pre-set interval is less than first
Proportion threshold value, and RSRP is more than the user equipment accounting of the first predetermined power threshold value less than the second preset ratio threshold value, then increases
