The embodiment of the present invention provides a kind of base station collocation method, as shown in Figure 1, this method includes：
S101, Multi-Mode Base Station obtain the edges cover performance parameter of the first supported standard network.Wherein, first system
Formula network is any standard network that the Multi-Mode Base Station is supported.
S102, the Multi-Mode Base Station determine the network coverage existing for the first standard network according to the edges cover performance parameter
Problem.
S103, the Multi-Mode Base Station adjust the transmission power of the first standard network according to the network coverage problem so that should
The transmission power of first standard network meets network coverage requirement.
Optionally, which includes cell edge coverage strength, if the cell of the first standard network
Edges cover intensity SnLess than cell edge coverage threshold STHR n, then the Multi-Mode Base Station determine the first standard network there are sides
The weak covering problem of edge.
Illustratively, which receives the downlink reception letter that all user equipmenies of the first standard network coverage are sent
Number power, and count the CDF of all down receiving signal power (Cumulative Distribution Function tire out

It should be noted that the downlink signal power that the user equipment covered by the first network standard is received is equal to
The transmission power of first network standard subtracts the Multi-Mode Base Station to the path loss of user equipment, and therefore, which should
The transmission power P of first standard networknIncrease STHR n-SnOr PHRAfterwards, since path loss is constant, what which received
Downlink signal power also increases STHR n-SnOr PHR。
If in this way, should, then the Multi-Mode Base Station is by the transmission power P of the first standard networknIncrease
STHR n-SnAfterwards, the cell edge coverage strength S of the first standard networknIt is increased to Sn+STHR n-Sn=STHR nSo that this first

The transmission power P of networknIncrease PHRAfterwards, the cell edge coverage strength S of the first standard networknIt is increased to Sn+PHR, at this point,
Cell edge coverage strength after first standard network increase is still less than STHR n。
Therefore, further, the Multi-Mode Base Station is according to power headroom PHRIncrease the transmitting work(of the first standard network
Rate PnLater, however, it is determined that the transmission power P after the first standard network increasen' with increase before transmission power PnDifference Pn′-Pn<
STHR n-Sn(the cell edge coverage strength i.e. after the first standard network adjustment is still less than STHR n), then the Multi-Mode Base Station obtains
Take the cell edge coverage strength S of the second standard networkm, which is the institute in addition to the first standard network
Any standard network for stating Multi-Mode Base Station support, if the cell edge coverage strength S of the second standard networkmMore than cell edge

In this way, the Multi-Mode Base Station is by power headroom PHRAfter all increasing to the first standard network, if the first standard net
The cell edge coverage strength of network is still unsatisfactory for cell edge coverage threshold STHR n, since the general power of the Multi-Mode Base Station is certain
, therefore, the transmission power which can will meet other standard networks that covering requires reduces, continue to increase this
The transmission power of one standard network, wherein if above-mentioned second standard network meets Sm-STHR m>=STHR n-Sn-PHR, then the multimode

Sm-STHR mAfterwards, the cell edge coverage strength of the first standard network is Sn+PHR+Sm-STHR m, still less than the cell edge
Coverage threshold STHR n, at this point, the Multi-Mode Base Station can obtain the cell edge coverage strength of other standard networks, and according to above-mentioned
Flow is adjusted at least once, and the cell edge coverage strength of the first standard network is equal to after transmission power increase
STHR n。
Optionally, which includes cell edge coverage strength and cell edge coverage distance, if should
Cell edge coverage strength SnMore than cell edge coverage threshold STHR n, and cell edge coverage distance DnMore than plot planning
Radius Rn, then the Multi-Mode Base Station determine that the first standard network crosses covering problem there are cell, and by the first standard network
Transmission power reduces Sn-STHR n。
Illustratively, which obtains between all user equipmenies and the Multi-Mode Base Station of the first standard network coverage
Distance value, and count the cumulative distribution function CDF of all distance values, 95% corresponding distance value of cumulative distribution probability made
For cell edge coverage distance Dn。
Wherein, which obtains between all user equipmenies and the Multi-Mode Base Station of the first standard network coverage
Distance value includes：The range measurement message of user equipment transmission is received, which includes that the user equipment is sent
Sending time mark when the range measurement message；Obtain receiving time mark when receiving the range measurement message；According to this
Sending time identifies and receiving time mark calculates the distance between the Multi-Mode Base Station and the user equipment value.
It should be noted that the difference of receiving time mark and sending time mark is the Multi-Mode Base Station and the user
Signal transmission time delay between equipment, in this way, since signaling rate is the light velocity, the Multi-Mode Base Station and the user equipment
The distance between can be calculated and obtain by the signal transmission time delay and the product of the light velocity.
Optionally, the Multi-Mode Base Station is before receiving the range measurement message that the user equipment is sent, to the user equipment
The system time for sending the Multi-Mode Base Station, so as to the user equipment according to the system time of the Multi-Mode Base Station to the sending time mark
Knowledge is calibrated.
Since the time between the Multi-Mode Base Station and the user equipment may be inconsistent, that is to say, that for synchronization,
The Multi-Mode Base Station may be different for the time identifier of the synchronization from the user equipment, and therefore, which is obtaining
Before the distance between user equipment value, the system time of the Multi-Mode Base Station can be sent to the user equipment, so as to the use
Family equipment calibrates sending time mark according to the system time of the Multi-Mode Base Station.
Further, if cell edge coverage strength SnMore than cell edge coverage threshold STHR n, and the cell edge
Coverage distance DnMore than plot planning radius Rn, then the Multi-Mode Base Station transmission power of the first standard network is reduced into Sn-
STHR nSo that the cell edge coverage strength S after the first standard network reductionnEqual to STHR n, solve the first standard net
Network crosses covering problem, and saves more power headroom P for the Multi-Mode Base StationHR。
Using the above method, Multi-Mode Base Station obtains the edges cover performance parameter of the first standard network, and according to the edge
Covering performance parameter determines network coverage problem existing for the first standard network, according to the network coverage problem adjust this first
The transmission power of standard network so that the transmission power of the first standard network meets network coverage requirement.In this way, the multimode base
It stands and is based on network covering property parameter automatic identification network coverage problem, and each standard net that voluntarily adjustment Multi-Mode Base Station is supported
The transmission power of network solves the problems, such as the network coverage caused by power configuration is improper, realizes that the general power of Multi-Mode Base Station exists
Reasonable distribution finds the network coverage to meet network coverage requirement compared to existing tested by manual site between multi-mode networks
Reconfiguring for transmission power is carried out again after problem, it is more efficient, and avoid manpower consumption.
In order to enable those skilled in the art to be more clearly understood that a kind of base station configuration side provided in an embodiment of the present invention
The technical solution of method carries out specifically a kind of base station collocation method provided by the invention below by specific embodiment
It is bright, as shown in Fig. 2, including：
S201, Multi-Mode Base Station obtain the cell edge coverage strength S of the first standard networknWith cell edge coverage distance Dn。
Specifically, which receives the downlink reception letter that all user equipmenies of the first standard network coverage are sent
Number power, and the cumulative distribution function CDF of all down receiving signal power is counted, cumulative distribution probability 5% is corresponding
Down receiving signal power is as cell edge coverage strength Sn。
Illustratively, which obtains the downlink that all user equipment measurements report in the area of coverage according to predetermined period and connects
Signal power is received, detailed process is：The Multi-Mode Base Station by RRC (Radio Resource Control) layer signalings in
The user equipment sending measuring control message of connection status, indicates that the user equipment is measured and reported under serving cell and adjacent area
The information such as row received signal power, the user equipment receive measure control message after, according to the message instruction execute measure and
Assessment, and measurement result is reported to the Multi-Mode Base Station.
For example, using all down receiving signal power as sample space, be denoted as Pr1, Pr2 ..., PrM }, M
For the number for the down receiving signal power parameter sample point that the period counts on, then the Multi-Mode Base Station, which determines, is based on sample space
The cumulative distribution function CDF of { Pr1, Pr2 ..., PrM }, and by 5% corresponding down receiving signal work(of cumulative distribution probability
Rate is as cell edge coverage strength Sn, using Fig. 3 for example, the horizontal axis of CDF curves is down receiving signal power P r, the longitudinal axis
For cumulative distribution probability F (Pr), wherein F (Pr)=P (Pri<Pr), Pr is independent variable, Pri indicate sample space Pr1,
Pr2 ..., PrM in down receiving signal power, then F (Pr) indicate in sample space { Pr1, Pr2 ..., PrM }
Down receiving signal power be less than independent variable Pr probability, therefore, as shown in Figure 3, when independent variable Pr be Min Pr1,
Pr2 ..., PrM } when, down receiving signal power is general less than the Pr in sample space { Pr1, Pr2 ..., PrM }
Rate is 0, i.e. F (Pr)=0；When independent variable Pr is more than Max { Pr1, Pr2 ..., PrM }, sample space Pr1,
Pr2 ..., PrM in down receiving signal power less than the Pr probability be 1, i.e. F (Pr)=1.Such as Fig. 3, the multimode base
It is that the corresponding down receiving signal power P r of 5% (i.e. F (Pr)=0.05) are covered as cell edge to stand cumulative distribution probability
Intensity Sn。
It should be noted that the Multi-Mode Base Station is using 5% corresponding down receiving signal probability of cumulative distribution probability as small
Area edge coverage strength SnOnly a kind of preferred embodiment of the invention, for example, the Multi-Mode Base Station can also will be by iterated integral
10% corresponding down receiving signal probability of cloth probability is as cell edge coverage strength Sn, this is not limited by the present invention.
Similarly, which obtains between all user equipmenies and the Multi-Mode Base Station of the first standard network coverage
Distance value, and count the cumulative distribution function CDF of all distance values, using 95% corresponding distance value of cumulative distribution probability as
Cell edge coverage distance Dn。
Illustratively, all distance values are as sample space { d1, d2 ... ..., dM }, the sample space d1, d2 ... ...,
DM } CDF curves as shown in figure 4, the Multi-Mode Base Station by cumulative distribution probability be the corresponding distance in 95% (i.e. F (d)=0.95)
Value d is as cell edge coverage distance Dn, similarly, the Multi-Mode Base Station is using 95% corresponding distance value of cumulative distribution probability as small
Area edge coverage distance DnOnly a kind of preferred embodiment of the invention, for example, the Multi-Mode Base Station can also will be by iterated integral
90% corresponding distance value of cloth probability is as cell edge coverage distance Dn, this is not limited by the present invention.
Specifically, which obtains between all user equipmenies and the Multi-Mode Base Station of the first standard network coverage
Distance value include：The Multi-Mode Base Station receives the range measurement message that user equipment is sent, which includes the use
Family equipment sends the sending time mark when range measurement message；It obtains when the user equipment receives the range measurement message
Receiving time identifies；It is calculated between the Multi-Mode Base Station and the user equipment according to sending time mark and receiving time mark
Distance value.
It should be noted that the difference of receiving time mark and sending time mark is the Multi-Mode Base Station and the user
Signal transmission time delay between equipment, in this way, since signaling rate is the light velocity, the Multi-Mode Base Station and the user equipment
The distance between can be calculated and obtain by the signal transmission time delay and the product of the light velocity.
Optionally, the Multi-Mode Base Station is before receiving the range measurement message that the user equipment is sent, to the user equipment
The system time for sending the Multi-Mode Base Station, so as to the user equipment according to the system time of the Multi-Mode Base Station to the sending time mark
Knowledge is calibrated.
Since the time between the Multi-Mode Base Station and the user equipment may be inconsistent, that is to say, that for synchronization,
The Multi-Mode Base Station may be different for the time identifier of the synchronization from the user equipment.
Therefore, illustratively, which before value, can set at a distance from acquisition is between user equipment to the user
Preparation gives the system time T of the Multi-Mode Base StationBS, which calculates the system time T of the Multi-Mode Base StationBSIt is set with the user
Standby side time TUEBetween time deviation △ T=TBS-TUE, in this way, the user equipment is obtained when sending the range measurement message
User equipment side time when sending the range measurement message is taken, and user equipment side time increase △ T are obtained into the transmission
Time identifier.
S202, the Multi-Mode Base Station judge cell edge coverage strength SnWhether cell edge coverage threshold S is more thanTHR n。
Specifically, cell edge coverage threshold STHR nIt can be pre-set by user, to weigh first standard
Whether the transmission power of network meets the requirement of edges cover intensity.
Wherein, if cell edge coverage strength SnMore than cell edge coverage threshold STHR n, then follow the steps S203
With step S204, if cell edge coverage strength SnLess than cell edge coverage threshold STHR n, then follow the steps S205 extremely
Step S211；If cell edge coverage strength SnEqual to cell edge coverage threshold STHR n, then stop to first standard
The adjustment of network launches power terminates flow.
S203、SnMore than STHR nWhen, if cell edge coverage distance DnMore than plot planning radius Rn, then the multimode base
Standing, there are cells to cross covering problem for the determining first standard network.
S204, the Multi-Mode Base Station are by the transmission power P of the first standard networknReduce Sn-STHR n。
In this way, the transmission power P after the first standard network reductionn'=Pn-(Sn-STHR n), due to the first network system
The transmission power that the downlink signal power that the user equipment that formula is covered receives is equal to first network standard subtracts the Multi-Mode Base Station
To the path loss of user equipment, therefore, the Multi-Mode Base Station is by the transmission power P of the first standard networknReduce Sn-STHR n
Afterwards, since path loss is constant, the downlink signal power which receives also reduces Sn-STHR n, correspondingly, downlink reception
The CDF curves (as shown in Figure 3) of signal power deviate S to the leftn-STHR n, i.e. cell edge coverage strength also reduces Sn-STHR n,
That is, the cell edge coverage strength of the first standard network after transmission power reduction is Sn-(Sn-STHR n)=
STHR n, at this point, the cell edge coverage strength of the first standard network meets cell edge coverage threshold requirement, and solve small
Covering problem is crossed in area.In addition, the transmission power for reducing the first standard network is equivalent to more than the power for increasing the Multi-Mode Base Station
Measure PHR。
S205、SnLess than STHR n, which determines the first standard network, and there are the weak covering problems in edge.
S206, the Multi-Mode Base Station inquire current power headroom PHR, and judge power headroom PHRWhether it is greater than or equal to
STHR n-Sn。
It should be noted that the general power of Multi-Mode Base Station is certain, all standard networks which is supported
The sum of transmission power be less than or equal to the general power of the Multi-Mode Base Station.Therefore, which is the total of the Multi-Mode Base Station
Difference between the sum of transmission power of power and all standard networks.
Wherein, if PHRMore than or equal to STHR n-Sn, then follow the steps S207；If PHRLess than STHR n-Sn, then follow the steps
S208。
The transmission power of the first standard network is increased S by S207, the Multi-Mode Base StationTHR n-Sn。
As the above analysis, transmission power increases STHR n-SnThe cell edge covering of the first standard network afterwards is strong
Degree is Sn+(STHR n-Sn)=STHR n, at this point, the cell edge coverage strength of the first standard network meets cell edge covering
Threshold requirement solves the weak covering problem of cell edge.
The transmission power of the first standard network is increased P by S208, the Multi-Mode Base StationHR。
Similarly, transmission power increases PHRThe cell edge coverage strength of the first standard network afterwards is Sn+PHR, due to
PHRLess than STHR n-Sn, therefore the cell edge coverage strength of the first standard network is still less than STHR n。
The transmission power P of S209, the Multi-Mode Base Station after determining that the first standard network increasesn' with increase before transmitting
Power PnDifference Pn′-Pn<STHR n-SnWhen, obtain the cell edge coverage strength S of the second standard networkm。
Specifically, the transmission power P after which increasesn' with increase before transmission power PnDifference Pn′-Pn
<STHR n-Sn, show that the transmission power increases PHRThe cell edge coverage strength of the first standard network afterwards is still less than STHR n,
At this time, it may be necessary to further increase the transmission power of the first standard network.
If S210, cell edge coverage strength SmMore than the cell edge coverage threshold S of the second standard networkTHR m,
Then the Multi-Mode Base Station is by the transmission power P of the second standard networkmReduce min { Sm-STHR m, STHR n-Sn-PHR}。
It should be noted that in the specific implementation, if the cell edge coverage strength of the second standard network is less than or equal to
The cell edge coverage threshold of the second standard network, then the Multi-Mode Base Station can reacquire the cell of next standard network
Edges cover intensity, until being more than the standard network of cell edge coverage threshold until getting cell edge coverage strength.
S211, the Multi-Mode Base Station by the first standard network increase after transmission power Pn' increase min { Sm-STHR m,
STHR n-Sn-PHR}。
In this way, the Multi-Mode Base Station is by power headroom PHRAfter all increasing to the first standard network, if the first standard net
The cell edge coverage strength of network is still unsatisfactory for cell edge coverage threshold STHR n, since the general power of the Multi-Mode Base Station is certain
, therefore, which can reduce the transmission power of other standard networks, continue the hair for increasing the first standard network
Penetrate power, wherein if above-mentioned second standard network meets Sm-STHR m>=STHR n-Sn-PHR, then the Multi-Mode Base Station by this second
The transmission power P of standard networkmReduce STHR n-Sn-PHR, the transmission power P after which is increasedn' continue to increase
Big STHR n-Sn-PHRAfterwards, the cell edge coverage strength of the first standard network is STHR nSo that the first standard network
Transmission power meets network coverage requirement；If Sm-STHR m<STHR n-Sn-PHR, then the Multi-Mode Base Station is by the second standard network
Transmission power PmReduce Sm-STHR m, the transmission power P after which is increasedn' continue to increase Sm-STHR mAfterwards, should
The cell edge coverage strength of first standard network is Sn+PHR+Sm-STHR m, still less than cell edge coverage threshold STHR n,
At this point, the Multi-Mode Base Station can obtain the cell edge coverage strength of other standard networks, and with reference to above-mentioned steps S209 to step
Rapid S211 is adjusted at least once, for example, for cell edge coverage strength SqMore than cell edge coverage threshold STHR q's
Third standard network, at this point, the transmission power of third standard network should be reduced Min { S by the Multi-Mode Base Stationq-STHR q,STHR n-
Sn-PHR-Sm+STHRm, the transmission power of the first standard network is increased into Min { Sq-STHR q,STHR n-Sn-PHR-Sm+STHRm}。
It is covered it should be noted that the above method is the network that any standard network supported for the Multi-Mode Base Station carries out
