Description
Technical field
The present invention relates to data analysis technique fields, and in particular to a kind of method of user's space positioning, especially mobile phone
The accurate positioning method of user.
Background technique
With the improvement of people's living standards, mobile phone early has become no matter wherein everyone daily necessities are all
Mobile phone can be carried.Mobile phone will realize network savvy, must be communicated with nearest base station, when mobile phone is from a base station
Coverage area when being moved to the coverage area of another base station, automatically switch to and be attached with another base station, therefore, led to
The motion profile for crossing observation mobile phone may know that the motion profile for carrying the people of the mobile phone.But due to the coverage area of base station
It is a face, can only knows that the mobile phone occurs in the coverage area of the base station, but not know the specific location of appearance.Together
When, in order to guarantee the stability of phone network, same place may there are multiple base stations to cover, when mobile phone is from different
When position enters the place, the base station of connection is different, if there is such case, is just unable to judge accurately the movement rail of mobile phone
Mark.In addition, since the coordinate of same geographical entity building is the set of a coordinate points, while having multiple base stations and it is carried out
Covering or geographical entity wing are covered by the base station A, and another part is covered by the base station B, when mobile phone user exists
When in geographical entity building, different base stations may be connected, or when mobile phone user is mobile in the geographical entity is built,
Also the switching that base station can occur, impacts to accurate positioning.
Positioning, which is carried out, currently with communication operation quotient data is mainly the following mode:
1, MR signaling data fingerprint location: the MR data comprising location information are trained for fingerprint base, by not position
MR carries out fingerprint matching forming position information according to feature.
2, MR signaling multipoint positioning: according to cell and at least adjacent cell signal receives field strength and path loss formula and receipts
Send out time difference calculating distance.
It is generally presented with positioning result of the upper type to user with 100*100 meters of grid fashions.I.e. by map according to longitude and latitude
Degree is divided into the grid of 100*100 meters of grid types, and user is positioned in the form of grid, only knows user in which grid
In lattice, but the specific location of user is not known.Simultaneously when 100*100 meters of grid positioning, the grid artificially divided does not have yet
Any representative meaning, without reference to value.
In existing MR signaling data fingerprint location, for training the MR data comprising location information of fingerprint to need work
Personnel carry out frequency sweep, drive test carries out actual measurement, or are parsed and provided using the OTT data comprising location information.Frequency sweep, drive test etc.
Mode needs a large amount of human resources, general only to carry out to small range region, it is difficult to carry out extensive drive test.And on the other hand, OTT
Data resolution factor is not high, and parsing difficulty also makes greatly this method be difficult to carry out large-scale production and application.
And MR multipoint positioning can not support MR since branch company, common carrier each province IT system construction degree is different comprehensively
The parsing of history large-scale data is cleaned, and user's history continuous path data are formed, and is normally only used for disposable positioning in real time and is asked
It asks, user's complete trajectory can not be continuously tracked.Meanwhile the positioning result of rasterizing is difficult to match with specific geographical location, quotient
Industry value is lower.
Summary of the invention
Mesh of the present invention provides a kind of method of user's space positioning, solve in the prior art cannot to mobile phone user into
The problem of row is accurately positioned.
The technical scheme adopted by the invention is as follows:
A kind of method of user's space positioning, comprising the following steps:
S1, base station engineering parameter, mobile service signaling data and Map Services quotient offer that common carrier provides are obtained
Space block actual position coordinate point set；
S2, pass through base station engineering parameter and space block actual position coordinate point set, formation geographical entity characteristic fingerprint；
S3, by traffic signaling data temporally, spatial relationship polymerize, determine that the traffic signaling track data of user is special
Sign；Due to being traffic signaling, i.e., one time point only one base station.But it, may be due to more since user is at a position
Base station switching can occur for kind factor, i.e., continuously a plurality of traffic signaling may be directed to a position to user, it is therefore desirable to will use
The traffic signaling at family is temporally, spatial relationship polymerize；
S4, according to the traffic signaling track data feature after polymerization, each period of mobile phone user is positioned, judge
User's specific geographic entity locating for each period.
As a preferred embodiment of the above technical solution, in the step S2, formed geographical entity characteristic fingerprint the step of are as follows:
S201, according to the covering surface of base station engineering parameter calculation base station；

Multiple switching then merges this two traffic signaling records；
Such as base station A- > ... the such switching of -> base station A, the time interval for such as occurring base station A twice are no more than 2 hours,
And the distance between other base stations occurred before the A of base station twice and base station A are no more than 1km, then merge these records；
S302, the traffic signaling data by time interval at 1 minute merge；
Since traffic signaling acquisition source is multiple data sources, and each data source time may have a little bit different, thus by when
Between be spaced in 1 minute traffic signaling data merge；
S303, iteration execute step S301 and step S302, until can not merge；
Record after S304, merging is divided into multiple periods by " beginning-end " time, and there are a plurality of notes in each period
Record, corrects mistake data, finds the longest base station of time of occurrence in each period, and rejects and be greater than in the period with the base station distance
The record of 1km；
S305, historical data study, by step S304 treated record deposit database, and with historical record carry out phase
It is matched like degree, similar historical record is incorporated to the period；
S306, each base station for occurring in same period is calculated in the frequency of occurrence W in nearly middle of the month；
Record after S307, output merging:
{U,Ts,Te,{Lc1,W1},{Lc2,W2},{Lc3,W3}…{Lcn,Wn}} (2)
