For example, during specific implementation, the raininess R of the terminal can be obtained according to formula one；
One: R=(γ of formulaR/k)α；
Wherein, the k and α is constant, γRDecayed by rainfall bring for the corresponding attentuation by rain rate of the terminal；
According to RPathLoss=23+PHR- (Noise-Gain+ULSINR+10lg (12 × NUMPRB)), obtain the terminal

Reason, obtains the rainfall of grid areas.
The method for measuring precipitation by communication base station in the present embodiment is similar with radar, is all to measure indirectly.But this reality
It applies in example and extrapolates precipitation intensity by detecting electromagnetic wave attenuation near the ground.Communication base station has a very wide distribution, density is big, signal frequency
Rate is more, therefore can provide continuously, in real time accurate Rainfall Monitoring near the ground, and manual maintenance workload is small, has whole day
Wait the condition for carrying out measurement.
The accuracy of above method measurement, which compares, relies on precipitation forecast model, such as K~R model and microwave link equipment
Distribution.The above method is using the canonical measure of rain gage bucket as a result, to the microwave attentuation by rain rate under 0.5~35GHz frequency with raininess
Between exponential relationship revised, and be exaggerated decaying caused by rainfall using the thought of raster overlay, to a certain extent
Improve measurement accuracy.
Particularly, it is merged, is further eliminated because environment reason bring is interfered by multivariate data in the present embodiment.
In addition, being obtained in the slave OMC in above-mentioned 201 each in each grid in a kind of optional realization scene
Before the metrical information that a base station is summarized, method shown in Fig. 2 may also include following the step of being not shown in the figure:
A01, OMC receive the measurement report that each base station is sent, according to the corresponding Timing Advance Ta of each measurement report

A02, if so, judging the measurement report whether measurement report belongs in pretreatment condition；
A03, if it is not, then the metrical information that the measurement report is summarized as the base station.
The terminal for meeting precipitation sampling condition in the present embodiment can be not at the phenanthrene of the base station covering for the terminal
The region Nie Er.
Particularly, if terminal does not meet precipitation sampling condition, the measurement report can be directly ignored during Rainfall estimation
It accuses.
In addition, the above-mentioned measurement report belonged in pretreatment condition, mainly screening measurement report, i.e., it will be due to base station
Measurement report caused by class defect abandons, not as determining the metrical information of rainfall.
The executing subject of above-mentioned Fig. 1 and method shown in Fig. 2 can be OMC, can also be after obtaining metrical information in OMC
It is executed by individual calculating treatmenting equipment such as rainfall server.
Atmospheric water condensate is obtained in the above method using the terminal survey report of mobile communication system to radio magnetic wave
The measurement of decaying；And then it is obtained using desired unbiased esti-mator and is declined the unbiased esti-mator of rate to rain；Larger range of drop can be achieved
The measurement of water distribution, without installing rain gage bucket, not increasing maintenance and collecting work amount；And can satisfy measurement accuracy, measurement essence
Degree is even better than radar surveying in the prior art, is also better than rain gage bucket measurement under given conditions, realizes that round-the-clock development is surveyed
Amount and acquisition.
Particularly, measurement report is utilized in the present embodiment, can also be achieved the beginning and ending time for differentiating rain.
To better understand above-mentioned Fig. 1 and method shown in Fig. 2, the present invention is implemented below in conjunction with the model of the prior art
The method of example is described in detail.
1) atmospheric water condensate Rain fade modes
It will receive the influence of particle in atmosphere when electromagnetic wave is propagated in an atmosphere, and generate and scatter, absorb, going to pole
The effects such as change and leads to the decaying of electromagnetic wave energy.If when being mingled with dampening condensate in atmosphere, water-setting object to electromagnetic wave this
Kind influences will be more significant, especially the shorter wave band of microwave and wavelength, and the conductivity of rainwater is higher, and raindrop size is close or big
In wavelength, when electric wave is propagated by rain belt, raindrop also scatter incident wave direction all directions in addition to absorbing part energy.
It is this be primarily due to water droplet decay caused by electromagnetic wave referred to as attentuation by rain.In a practical situation, attentuation by rain is with precipitation intensity, micro-
The factors such as the distance of wave link are related.This characteristic is based in the embodiment of the present invention, using precipitation for base station and user UE it
Between the decaying of transmission signal be finally inversed by precipitation intensity.
Currently, communication base station have have a very wide distribution, the big feature of density, generally honeycomb distributed network, base station with
Distance is generally not too large between base station, and in tens meters to one liang kilometer ranges, the signal of communication between base station is by precipitation
Influence can be embodied when decaying by the variation of electromagnetic wave power.It can be former based on Mie scattering in the embodiment of the present invention
Reason, it is assumed that under conditions of raindrop are spherical shape, what is utilized is the empirical mode (ITU-R is P.838-3) that International Telecommunication Association (ITU) provides,
The attentuation by rain forecasting model provided according to ITU-RP.838-2:
γR=kRα (1)
Wherein k and α is parameter, depends primarily on the related parameter such as frequency, the elevation angle and polarizing angle, and R is raininess (mm/h),
γRIt is attentuation by rain rate (dB/km).P.838.3 suggested according to ITU-R, can use following formula and k and α are calculated:
Wherein a, b, c, m are parameters, and f is microwave frequency.
Above-mentioned formula (1) reflects signal decaying with the exponential relationship between raininess, and calculating is simple and convenient, can be to avoid multiple
Miscellaneous theoretical calculation, and it is suitble to the electromagnetic wave of each frequency range of high latitude area in China place, and have preferable calculating essence
Degree.
2) terminal survey report
When terminal is in service connection state, not go offline when guaranteeing that terminal moves in cellular networks, terminal needs simultaneously
Measure the level of this cell and potential target adjacent area, so as to this Cell level drop to it is unacceptable before be switched to one in time
Level target adjacent area good enough, to realize the duration of connection.The mechanism is to including global system for mobile communications (Global
System for Mobile Communication, abbreviation GSM), Universal Mobile Communication System (Universal Mobile
Telecommunications System, abbreviation UMTS), including long term evolution (Long Term Evolution, abbreviation LTE)
All mobile communication system be just as effectively.By taking LTE as an example, terminal meeting periodically this cell of the measurement of (such as 2 seconds)
With the level (such as RSRP) of target adjacent area, base is reported in the form of measurement report (Measurement Report, abbreviation MR)
It stands, base station can collect these MR, and do necessary pretreatment, then be aggregated into OMC with the bigger period (such as 15 minutes).
Time division duplex (Time Division Duplexing, abbreviation TDD) system has the principle of uplink and downlink reciprocity, changes
The loss and the loss of uplink of the i.e. downlink of speech are always equal, use the multiple parameters for including in MR as meter in the embodiment of the present invention
Basis is calculated, obtains more accurately acquiring actual circuit loss value.Approaches uniformity distribution terminal under the same cell is to same neighbour
The measurement result in area pair meets independent same distribution requirement.A large amount of terminals spread in a network, which are formd, covers geographic region to base station
Seamless measurement in domain.
In practice, it is reported due to the presence of Fresnel region when macro station distance is too close to outside user distance room
There are obvious errors for MR data.And once user distance base station is too far, environmental disturbances are excessive, be unfavorable for the later period extract because rainfall is made
At decaying.Therefore, user is screened roughly with Timing Advance (Time Advanced, abbreviation Ta) in the present embodiment,
It will be screened out apart from the sampled point of website excessively closely or too far.From the point of view of many experiments empirical data, report Ta 3~10
Sampled point meets sampling condition.
3) path loss and raininess calculate
According to formula above-mentioned (1), raininess R can be acquired by formula (3), and wherein k and α is that constant can table look-up acquisition.As long as
According to the MR of mobile communications network be calculated each cell position γ value can in the hope of each cellular raininess, thus
Entire target geographical area can be extended to.
R=(γR/k)α (3)
As above, the statistical property needed for a large amount of terminal measurement meets, measurement expectation fall in main serving cell periphery
Meet unbiased esti-mator, practical path loss can be expressed from the next.
RPathLoss=23+PHR- (Noise-Gain+ULSINR+10lg (12 × NUMPRB)) (4)
Wherein, RPathLossFor path loss, in practical applications, due to Reference Signal Received Power (Reference Signal
Receiving Power, abbreviation RSRP) precision is not high, therefore use above-mentioned formula (4) this mode.
PHR is power headroom in formula (4), and Noise is that system carries noise (constant), and Gain is to receive diversity gain
(constant: if 8 antenna 9dB, 2 antenna 3dB), UL SINR are uplink signal-to-noise ratio, NUMPRBPhysical Resource Block uses number (the one of LTE
A parameter).
Above-mentioned formula (4) obtained value is that average road is declined value i.e. path loss, and the road value that declines is not merely since rainfall is drawn
It rises, further includes the factors such as space is freely lost, rapid fading, multi-path jamming and natural environment obstruct.In order to extract
It is required to decay as caused by rainfall, thus, using fine day value as R in the present embodimentbase.Polynary meteorological factor is introduced,
The data such as gas epidemic disaster, rainfall gauge data, weather radar data, satellite cloud picture, as improvement factor, as far as possible also
The decaying of signal caused by former actual environment.Finally, decay caused by rainfall:
γR=Rpathloss-Rbase+Cenv+Cweather (5)。
4) amplification of rainfall attenuation
It is standardized according to (ITU-R is P.838-3), the upper embodiment of the present invention has carried out mathematical modeling on Matlab2017, obtained
It has arrived (1.9Ghz~2.1Ghz) under the conditions of existing net, user's theoretical attenuation value caused by rainfall within the scope of 1km.The theoretical attenuation
Value and measured data are due to that more or less all can cause pad value with the presence of ponding on actual antenna for base station there are error
It is bigger than normal than theoretical.However, decay caused by rainfall still less than normal, be not able to satisfy this programme pair under existing net acquisition condition
The demand of precision.Therefore, identical feature is worth using a small range rainfall.All basic station over network is divided in the grid of N number of 1km x 1km
In lattice.The decaying that each base station is acquired is overlapped, achievees the purpose that amplifying rainfall causes decaying.
As shown in figure 3, right side is the original weather station data of the whole province in Fig. 3, left side is the measurement of present invention method
Data, by the comparisons of two figures as can be seen that the measurement result in the present invention under experiment condition is basic identical with practical rainfall,
Although there are still small-scale precipitation susceptibilitys there are still deficiency, error is more than the region of 5mm less than 17%；Rainfall error exists
The region of 10mm or more is less than 3%.
