As shown in Figure 1, this method comprises:
S1: signaling data is obtained.
S2: according to the phone number of the user carried in signaling data and corresponding with phone number international mobile respectively
EIC equipment identification code and international mobile subscriber identity generate the corresponding user identifier of user.
Wherein, IMEI (International Mobile Equipment Identity) is international mobile device identification
The abbreviation of code.International mobile subscriber identity (IMSI:International Mobile Subscriber
Identification Number) it is the mark for distinguishing mobile subscriber.
Due to individually using phone number as the corresponding user identifier of user, in fact it could happen that multiple user trajectories mixed
Situation.It is in the present embodiment, raw according to phone number, IMEI and IMSI in order to more accurately be identified to user identity
At the corresponding unique user identifier of user.To efficiently avoid the problem of user's wrong identification causes track to mix.
S3: dividing signaling data based on user identifier, obtains the corresponding base station handoff relation of user and switching time
Number.
It is understood that the amount of signaling data is very more.And the different corresponding signaling datas of user is not identical.
Therefore, it is necessary to the signaling datas to each user to distinguish.Since user identifier is uniquely, so user identifier can be based on
It is the differentiation to user, signaling data is distinguished.So in this step, by user identifier to the signaling number of magnanimity
According to being divided, it can be ensured that the technical effect precisely divided to magnanimity signaling data.And ensures base station handoff relation and cut
Change the reliability of number.

It is to cut or cut out according to corresponding event type, finds the type after screening to the signaling data for cutting or cutting out type
Signaling cannot really reflect user location track, and then cannot reflect positional relationship between base station, should give rejecting.
S3-2: it is sorted based on user identifier to target signaling data, obtains the corresponding base station sequence of each user.
Since target signaling data records sequentially in time, the signaling data of different user is mixed in together,
It can not directly utilize.And target data polymerize and handle according to time-sequencing based on user identifier, single use can be formed
Base station sequence of the family with timestamp.
S3-3: base station corresponding with user handoff relation is extracted from the corresponding base station sequence of each user.
In this step, the corresponding base station switching of user's motion track can be extracted according to the user identifier of each user

Now the concrete scheme of S3-3 is illustrated in the form of specific example.Such as:
According between the base station in base station distribution sparse regional (for example, along village, high-speed rail etc.), (such as 5 is public by average distance d
In), using high-speed rail speed (such as 300 kilometers/hour) as speed limit v, obtain produced two signalings of normal position variation
Time interval upper limit Δ tmax,
Δtmax=d/v
It calculates between two signaling datas adjacent in each user time (two adjacent base stations that there is handoff relation)
Time difference Δ tn=tn-tn-1.If Δ tn≤Δtmax, then by tnAnd tn-1Corresponding base station A and B forms base station handoff relation
(A,B)。
S3-4: according to the corresponding base station handoff relation of each user, obtain the corresponding base station handoff relation of all users and
The switching times of base station handoff relation.
In this step, the corresponding base station handoff relation of all users is converged, the base station handoff relation of full dose and right is formed
The switching times answered.It is understood that flow of the people is bigger, base station covers more intensive area, corresponding more base station switching
Relationship and switching times.
For example, it is assumed that 2 user's first and second are co-existed in, if the base station handoff relation that first extracts in (1) is (A, B),
(B, C), (C, D), the base station handoff relation that second extracts in (1) are (B, C), (C, E).Base station handoff relation after convergence and
Quantity are as follows: (A, B): 1 time, (B, C): 2 times, (C, D): 1 time, (C, E): 1 time.
S4: it is scored based on base station handoff relation, the confidence level of switching times calculation base station.
In a kind of technical solution in the cards, S4 is specifically included:
S4-1: the longitude coordinate and latitude coordinate of two base stations in each base station handoff relation are obtained.
S4-2: the distance between two base stations in each base station handoff relation is calculated based on longitude coordinate and latitude coordinate.

Wherein, r is earth radius, latAFor the corresponding latitude coordinate of base station A, latBFor the corresponding latitude coordinate of base station B,
lonAFor the corresponding longitude coordinate of base station A, lonBFor the corresponding longitude coordinate of base station B, and latA、latB、lonA、lonBUse arc
Degree tabulation is shown.
That is to say, base station A, B corresponding for any base station handoff relation (A, B), extract theirs from existing record
Latitude and longitude coordinates (lonA,latA)、(lonB,latB), based on the distance between formula 1 calculation base station A and B distA,B。
S4-3: it is determined based on the distance between two base stations in each base station handoff relation apart from median.
S4-4: based on base station handoff relation, switching times, distance and apart from median determine confidence level score.
In a kind of technical solution in the cards, S4-4 is specifically included:
