Description
Technical Field
The present disclosure relates to big data technologies, and in particular, to a space-time matching method and apparatus for multiple signaling tracks.
Background
The matching technology of the signaling track of the mobile terminal has important application in the aspects of similar track identification, peer judgment, trailing person early warning and the like. The prior art has the following technical defects:
first, the tracks have limited matching capability on a time scale.
The prior art performs distance similarity calculation in a weighted form by a method of regarding dwell time as a position weight. But the comparison of the time to reach the position is omitted. Theoretically, the closer the two tracks arrive at the same position, the closer the time to stay, the greater the similarity of the two tracks. However, the prior art focuses only on dwell time, with limited matching capability on the time scale.
Second, the effect of the direction of movement on the spatial matching result is not considered.
In the prior art, distances of different tracks in European space are calculated and used as references for similarity judgment. But the prior art ignores the effect of the direction of movement on the matching result. In theory, although the distance between each pair of position points is far, they are spatially parallel, i.e. the moving direction is the same, so that the similarity between the two tracks is still high. However, the prior art only focuses on Euclidean distance, but ignores the influence of the moving direction on the matching result.
In view of the above drawbacks, the problems to be solved by the present application are: based on limited signaling observation values, how to achieve the matching effect on similar tracks through a time and space analysis technology.

The space-time matching method of the multi-signaling track in the embodiment of the application is further described below with reference to a specific embodiment scheme, specifically:
first, the basic data is preprocessed.
The base data includes base station location data and terminal signaling data.
The base station position data comprises a position area code (location area code, LAC) of the base station, a CELL value of the CELL and longitude and latitude coordinates corresponding to each pair of LAC and CELL. The preprocessing of the base station position data is embodied in that the corresponding longitude and latitude is searched according to the LAC and CELL values of each base station, namely, the longitude and latitude of the base station is determined (taking a WGS84 coordinate system as a reference).
The terminal signaling data comprises LAC and CELL values when the terminal communicates with the base station and the time when the communication occurs. The preprocessing of the terminal signaling data is embodied in that the position of the terminal is initialized, namely, the coverage area of the terminal in which base station is positioned at the moment is determined according to the time and LAC and CELL values, and the longitude and latitude of the base station are initialized to the position of the terminal.
Second, a signaling trace bundle is calculated.
The signaling track beam is a track vector M from a first base station position to a second base station position, a departure time T1 from the first base station position, an arrival time T2 from the second base station position, a residence time deltaT 1 at the first base station position and a residence time deltaT2 at the second base station position; the first base station position and the second base station position are two base station positions through which the terminal sequentially passes in turn.
Fig. 2 is a schematic diagram of a calculated signaling track beam provided in an embodiment of the present application, where (a) in fig. 2 is a certain signaling observation sequence, and A1, B2, B3, C1, D2 are base station CELLs uniquely determined by LAC and CELL, and (B) in fig. 2 is a track beam generated by calculation, where A, B, C, D is a position (longitude and latitude) corresponding to a different base station CELL. The calculation process is as follows:
step s201, signaling base station location aggregation.
As shown in fig. 2, in the continuous signaling observation, if the latices and latitudes corresponding to LAC and CELL at a certain moment are the same as each other, for example, B1, B2, B3 and D1, D2, then these records are combined, and the record positions B and D are the positions of the time period. In other cases, if A1 and C1 are used, the time position is directly recorded A, C.
Step s202, calculating track beam parameters.
The track beam parameters are (lambda, T, delta T), wherein lambda is the track beam vector, T is the track beam starting time, and delta T is the residence time. As shown in fig. 2 (B), for two consecutive positions A, B, the observation of position B is (x) b ，y b ，t 2 ，t 4 ) Wherein x is b 、y b Is the longitude and latitude of the position, t 2 ，t 4 For the time of arrival at the B-position and the time of departure from the B-position. The observation of the corresponding position a is (x a ，y a ，t 1 ，t 1 ) The arrival and departure times at this time are the same. Then the track parameter is
λ＝((x b -x a ),(y b -y a ))
Tb＝t2
Ta＝t1
Δt b ＝t 4 –t 3
Δt a ＝0
Third, time matching of signaling traces.
The time matching of the signaling trace includes: after the steps, the matching times of the two groups of observation signaling in time are calculated, compared with a target threshold value, and two groups of signaling track pairs which are more than the threshold value and accord with time matching are screened out.
Fig. 3 is a schematic diagram of time matching provided in an embodiment of the present application. Fig. 3 (c) is a set of observation signaling to be matched, wherein A, D, C, B is the timing position, t 1 ' is the observation time of position A, t 2 ' is the observation time of position C. Fig. 3 (d) is another set of observation signaling to be matched, where A, B, C, D is the timing position, t 1 For the observation time of position A, t 2 For the entry time of position D, t 3 For the departure time of position D, ε is a specified reserved time parameter, ε>0. The calculation of the time matching of the signalling is based on signalling (d) and for position A the calculation is based on [ (t) 1 -ε),(t 1 +ε)]Whether there is an observed location in the time frame signaling (c), and if so, considering an A location hit on (d). For position D, calculate [ (t) 2 -ε),(t 3 +ε)]Whether there is an observation location in the in-range signaling (c), and if so, deeming a D-location hit on (D). And others alike. Finally, the hit rate of (d) is calculated as follows:
wherein, gamma b For hit rate, N is the number of hit positions, and N is the total number of positions. Similarly, the hit rate gamma of (c) is calculated based on (c) a . The final hit rate γ for both sets of signaling is:
γ＝max(γ a ,γ b )
if γ is greater than the set time hit rate threshold, they pass time matching. Otherwise, the time matching is not passed.
And fourthly, spatial matching of signaling tracks.
The spatial matching of the signaling tracks comprises: and judging whether the positions of the two groups of track positions meet the matching requirement for the positions in the signaling track matched with the elapsed time. If so, calculating the hit rate of the space; if not, their spatial hit rate is 0. And finally judging whether the space hit rate is larger than a threshold value, if so, passing space matching, and if not, not passing.
Fig. 4 is a schematic diagram of signaling track space matching principle provided in an embodiment of the present application. A. B is two sets of signaling, A1-A6 and B1-B5 are respectively continuous time sequence positions, wherein A2-A6 and B1-B5 are matched through time. The method for performing space matching on the position passing the space matching comprises the following steps:
step s401, spatial position matching.
The spatial position matching comprises the following steps: and B is used as a reference signaling, a buffer area taking the position as a unit is established for each position, if the corresponding moment in A has the position in the unit buffer area, the position in B passes through position matching, and otherwise, the position does not pass through. The buffer zone is a circle in space with a certain position as a center and a certain length as a radius. The circle covers the buffer area of the position.
For example, A 4 And B 3 Are the same location, they are matched by location. A is that 5 Is a circle P, B 4 Within its buffer, then A 5 And B 4 By position matching. However, B 1 At A 2 They do not pass the position match.
Based on the track positions meeting the position matching condition, firstly taking (a) as a reference, establishing a buffer unit taking each position as a center, and calculating the hit rate, wherein the hit rate is larger than a threshold value, the position matching is passed, and otherwise, the hit rate is not passed.
Wherein N is the number of positions in (a) matching with (b), N is the total number of positions in (a), λ a Is the spatial hit rate. Similarly, the hit rate lambda is calculated based on (b) a . The final location hit rate λ for the two sets of signaling is:
λ＝max(λ a ,λ b )
if λ is greater than the set location hit threshold, they pass location matching. Otherwise, the position matching is not passed.
Step s402 calculates the space-time hit rate
The said calculation of the space-time hit rate means that for two track bundles that pass through the position matching, the probability of them hit in space-time is calculated, if the probability is greater than the threshold, they hit in space-time, otherwise they miss. And finally calculating the space-time hit rate. If the space-time hit rate is greater than the threshold, the matching is passed, otherwise the matching is not passed.
Where N is the number of track bundles hit in space, N is the number of track bundles formed by position points matched in position, and k is the space hit rate.
The process of calculating the probability of two track bundles hitting in space is that,
h＝a 1 cosθ+a 2 e- |ΔT| +a 3 e- |Δt|
for example two track bundles as in fig. 4And->Wherein the included angle of the two vectors is theta, and the space hit probability of the two vectors is calculated as follows:
wherein a is 1 、a 2 、a 3 And h is the hit probability, which is the probability adjustment coefficient.
The embodiment of the application provides a space-time matching method based on a track beam. According to the method, a probability estimation model taking the track vector, the arrival time difference and the residence time difference as parameters is established according to the track beam constructed by the track vector, the departure time and the arrival time, and then the probability of hit of the two track beams in space-time is calculated.
The embodiment of the application provides a position matching method based on unit buffer analysis. The method judges whether the position to be matched exists in the buffer zone or not by establishing the buffer zone taking the reference position as a unit, thereby judging whether the reference position is matched with the position to be matched or not.
According to the embodiment of the application, firstly, the tracks to be matched are subjected to time matching, then, the track sequences hit in time are subjected to space position matching, so that space-time matching probability calculation is performed on the track sequences matched through the space positions, and finally, the matching hit rate is calculated. In the matching process, the time matching, the position matching and the space-time matching probability are one, and the matching is unsuccessful if the matching condition is not met. According to the method and the device, under a multi-level matching mechanism, the matching error rate can be reduced.
The embodiment of the application introduces the track beam object with space-time dimension, reflects the space matching degree through the vector, and finally controls the influence weight of different matching modes on the hit probability through the arrival time and residence time reaction time matching degree. Therefore, the embodiment of the application can provide a track matching method for multiple modes such as similar positions, similar directions and similar time.

The space matching module of the signaling track is connected with the time matching module, after the time matching result is screened out by the module, whether the track bundles hit in time in the space hit is judged, the space hit rate is calculated, and finally the space matching result meeting the condition is screened out.
