Description
Technical field
The present invention relates to the mobile communication technology field, particularly relate to a kind of mobile subscriber track generation method and device.
Background technology
In user's mobile monitor technical field and other technologies field,, need accurately know the motion track of user in a period of time in order to grasp user's concrete whereabouts.
For the motion track of supervisory user, realize the regeneration of mobile motion track, the method that adopts mainly contains following five kinds at present:
One, rationalistic emulation technology.Rationalistic emulation technology is carried out on the plane freely at one, the user can move to more arbitrarily, a bit do not stop the restriction of number of users arbitrarily, this emulation technology is to set user's the time of staying and stop probability, traveling time and translational speed, moving direction, drive based on chance event, the final mobile result who forms macroscopic view is because this simulation model is fully not according to real user's moving characteristic, therefore only possess theoretical value, and do not have practical value.
Two, based on the emulation technology of current conditions.Based on the emulation technology of current conditions is improvement to the pure theory emulation technology, and plane is freely changed into road and two kinds of objects of building, and the user can only move along road, and is resident in building, and the user is divided into mobile person and resident person.This emulation technology is to set user's the time of staying and stop probability, traveling time and translational speed, moving direction.Set customer volume that can be resident, the area and the capacity correlative factor of building simultaneously, the customer volume that can flow is relevant with the size of road.Road and building derive from real map.Drive based on chance event, the final mobile result who forms macroscopic view, therefore this emulation technology, possesses certain reference value according to certain current conditions, but owing to be not according to real user's moving characteristic, does not therefore also have practical value.
Three, based on the technology of real traffic data.A lot of city traffic management departments monitor key road by camera, and can add up the dealing vehicle flowrate at each crossing, every road accurately.For traffic administration, this is the model of vehicle moving characteristic accurately, but for the cellphone subscriber, this model just has certain representative feature and inaccuracy, because vehicle is representative's flow not, such as several cellphone subscribers that decuple car of cellphone subscriber's possibility of a bus, and for different operators, not representing each passenger all is the cellphone subscriber.In addition, some non-key roads such as branch road and path can't be monitored and add up, and the overall flow of the people and the key road of path are suitable.Therefore, model that obtains based on the technology of traffic data and cellphone subscriber's moving characteristic have certain correlated characteristic, but can not represent fully.
Four, the technology of based on network statistics.The statistical function of network also provides the data of certain customers' moving characteristic, such as the statistics of the switching between two sub-districts, can represent two users' under the district calling state moving characteristic.Also having the amount of upgrading based on the position of moving, is the user's in all cross-location district the summation of amount of movement, is not the amount of movement between every pair of neighboring BS relationship.The technology of based on network statistics moving characteristic abstract from ground physics and chemistry be incidence matrices between sub-district and the sub-district, but not comprehensive, the amount of movement under the talking state can be provided, the amount of movement under the idle condition can not be quantized to the neighboring BS relationship rank.
Five, the modeling technique of based on network statistics.As described above, the technology of statistics Network Based can provide the quantification of part sub-district to the moving characteristic of sub-district, user position, but not comprehensive.Improved technology is the statistics position of the moving characteristic under the reaction idle condition to be upgraded do darker development and use.At user position cell boarder, the amount that the position is upgraded is that the community user in some cross-locations district enters this sub-district sum, therefore, can reasonably decompose amount of movement between each sub-district.The improvement of this technology is that the amount of movement under the idle condition between lane place and the border cell is had a quantification, and shortcoming is, can't accurately quantize for the amount of movement under the idle condition of inside, lane place.
Therefore, up to the present, also there is not a kind of method can be exactly the motion track of mobile network user to be described.

Embodiment
Core concept of the present invention is: the motion track between the sub-districts takes place in current two the continuous incidents that need regenerate for the user, detect earlier and judge whether these two sub-districts are neighbor cell, when these two sub-districts are non-conterminous, gathering the user is under the mobile status the various motion tracks between these two sub-districts always and writes down the used time, the time that various tracks are used and the time of origin of two continuous incidents compare at interval, select immediate track as the motion track between current two continuous incidents generation sub-districts at last.
For making those skilled in the art understand the present invention better, technical scheme provided by the invention is specified below in conjunction with specific embodiment.
In the mobile network, the user of mobile communication equipment can always not stay in the three unities, generally only will the occurrence positions change after a place stays for some time, perhaps the user is in the state when taking bullet train (as) of shift in position always in a period of time.
In view of the motion track of user in a period of time can show as geographically: the user stays for some time in a building earlier, moves along certain paths along driving then, up to another building the inside.So, corresponding user at the structural motion track of mobile network is: the user stays for some time under a network node, passes a series of network node then, stops below reaching another network node.
In view of this, user's motion track can be described by the mode of user's change in location track of sub-district, place in mobile communications network.
Fig. 1 is complete user's motion track schematic diagram.In Fig. 1, the user is in the A sub-district, the incident of being carried out is to have made a call one, this moment call detail record (Calling Detail Records, CDR) Time To Event noted down of information is that t1, cell information are specially: Location Area Identity (location area codeID, LAC ID) be x1, cell ID (CELL ID) is y1.Through the B sub-district, owing to be idle condition, user mobile phone is only accepted the information of network to the user, but does not send to network under idle condition, so CDR information the inside is without any record.The user is in the C sub-district, and the incident of being carried out is to have sent out a note, and the Time To Event that is write down by CDR information is t2, and cell information is: LAC ID=x2, cell ID CELL ID=y2.
The incident that the user is carried out in the E sub-district is to have done a position to upgrade, and the Time To Event that is write down by CDR information is time t3, and cell information is: LAC ID=x3, cell ID CELL ID=y3.The incident that the user is carried out in the F sub-district is to have sent out a note, and the Time To Event that is write down by CDR information is time t4, and cell information is: LAC ID=x4, cell ID CELL ID=y4.
As shown in the figure, the sub-district number of the true process of user is A, B, C, E, F, but because the sub-district of the generation incident that writes down is A in the CDR information, C, E, the F sub-district, do not have the B sub-district, because sub-district B is the switching sub-district that is in the process of user from the A sub-district to the C sub-district under the idle condition, in the B sub-district because mobile phone does not carry out signal contact with the base station, therefore, there is not CDR information record, therefore, Mobile Network Operator and do not know the switching process of user mobile phone from the A sub-district to the C sub-district the B sub-district particular location of process, CDR also can't know this sub-district by logout information, the part track that the just user of CDR record moves not is whole tracks that the user moves.
Need to prove that (Calling Detail Records CDR) has described the overall process of call proceeding to call detail record.The parameter that writes down in CDR comes from original signalling message data, by some important parameters in the record are further analyzed and handled, can provide the basis of analysis for fixed-line telephone network or mobile phone network service.
Referring to Fig. 2, flow chart for a kind of mobile subscriber track generation method provided by the invention, this method can know with estimating the user in twice continuous incident subdistrict position and twice continuous incident between the subdistrict position of process, thereby whole tracks that the user moves are described out.
May further comprise the steps:
Step S201: gather the recorded information of each incident that the user carried out, know the time of origin of each incident of user, the position that sub-district and neighbor cell thereof take place.
Be specially: gather user's call detail record CDR information, know the time of origin of each incident of user, the position that sub-district and neighbor cell thereof take place incident.
(Calling Detail Records, CDR) information has write down the time of origin of each incident in the overall process (as start, shutdown, conversation, event procedure such as transmitting-receiving note etc.) of user mobile phone call proceeding, the longitude and latitude that the sub-district takes place incident, the information such as longitude and latitude that the neighbor cell of sub-district takes place incident to described call detail record.
The positional information of described sub-district is the latitude and longitude information of sub-district.
Step S202: according to the position that each incident the sub-district takes place and the neighbor cell of sub-district takes place, whether the generation sub-district of any two continuous incidents of detection user is adjacent;
In view of CDR information has write down each incident the adjacent cell information of sub-district taking place, therefore, according to CDR information, can know whether the generation sub-district of two continuous incidents is neighbor cell.
If adjacent, then illustrate not have the switching sub-district between the generation sub-district of these two continuous incidents, carry out step S203: know that the user carries out moving continuously in the generation sub-district of described two continuous incidents;
If not, illustrate that then current two continuous incidents take place to have one or more switchings sub-district between the sub-district, enter step S204: various tracks that move in described any two continuous incidents generation minizones when the collection user is in communications status always and used traveling time are at interval.
Be specially: according to CDR information, know the user be under the communications status described two continuous incidents take place to move between the sub-districts each sub-district of process and used traveling time at interval;
According to the user move the sub-district of process, obtain the track of user in described two continuous incident generation moving between cells.
In view of the user when the generation moving between cells of two continuous incidents, usually the rectilinear direction near the generation sub-district of two continuous incidents moves, therefore, the motion track among the step S204 is preferably the track near the rectilinear direction of the generation sub-district of two continuous incidents.
According to the position of two continuous incidents generation sub-districts, can know the rectilinear direction of the generation sub-district of two continuous incidents.
Step S205: the time of origin of the time interval that the various tracks that move in described any two continuous incidents generation minizones when relatively the user is in communications status always are used and any two continuous incidents of current required detection at interval;
Step S206: motion track between the sub-districts takes place as the user in any two continuous incidents of current required detection in the at interval the most close motion track of select time.
By the said method flow process, can know the motion track of user between the sub-district of any two continuous incidents, thereby, can know whole motion tracks of user according to the motion track of user between per twice continuous incident generation sub-district.
By above-mentioned flow process provided by the invention, can know the track of mobile subscriber, thereby finally describe out whole motion tracks of mobile subscriber in any two most possible processes of continuous incident.With regard to instantiation technical scheme of the present invention is described below:
