For the first screening of step S102 ticket, namely " from user radio ticket, high ferro user ticket is filtered out based on the high ferro sector group set up ", the embodiment of the present invention proposes a kind of high ferro user ticket screening scheme, namely, to access and to be released in the user radio ticket of high ferro coverage cell for analytic target, in conjunction with the contiguous wireless talking list Conjoint Analysis of time in other high ferro coverage cell of same user, estimation user moving speed, utilizes the translational speed difference section of high ferro user and domestic consumer to separate high ferro user ticket in user radio ticket.
The high ferro user ticket screening scheme that one is exemplary is provided below, that is, the user radio ticket meeting the following conditions (1-3) is screened as high ferro user ticket:
Condition 1) user radio ticket access community and release community all in high ferro sector group.
Condition 2) user radio ticket discharges at it other wireless tickets having this user before and after moment in a period of time in high ferro sector group, and the distance between the release center of other wireless tickets of user radio ticket and this user exceedes predeterminable range.
Condition 3) user radio ticket had other wireless tickets of this user in a period of time before and after its release moment in high ferro sector group, and according to the distance between the release center of other wireless tickets of user radio ticket and this user and release time interval determine the translational speed of this user, the translational speed of this user exceedes pre-set velocity.Wherein, speed calculates can utilize existing formula v=d/t, and wherein, v represents the translational speed of user, and d represents the distance between two ticket release centers, and t represents interval release time of two tickets.
In above-mentioned screening conditions, wherein, before and after the user radio ticket release moment, a period of time can be arranged flexibly, such as, to be set to before and after the release moment in 1 hour; Predeterminable range between release center can be arranged flexibly, such as, is set to 10 kilometers; The pre-set velocity of high ferro user movement can be arranged according to the current high ferro speed of service, such as, is set to 120km/h.Those skilled in the art can adjust the concrete numerical value of aforesaid time, distance, speed etc. according to actual conditions, and the concrete numerical value of these parameters is not limited to examples cited.

In above-mentioned screening conditions, the release center of user radio ticket refers to the center that sector covers, and is used for the position (as longitude and latitude) of approximate representation user when discharging.In one embodiment, release center (that is, the center of sector covering) can be determined according to the antenna feeder work ginseng of sector in the Active Set of user radio ticket, specifically comprises step 1-3:
Step 1) hang high and antenna total angle of declination determination Active Set list branch covering radius according to antenna.Such as can adopt following formulae discovery:
r＝h/tan；
Wherein, r represents Active Set list branch (sector) covering radius, and h represents that antenna is hung high, and tan represents the total angle of declination of antenna.
Step 2) cover center longitude according to latitude and longitude of base station, antenna azimuth and covering radius determination Active Set list branch of Active Set list branch.Such as can adopt following formulae discovery:
lat(i)＝lat0+r×cos(rad(α))/(111×1000)；
lon(i)＝long0+r×sin(rad(α))/(111×1000×cos(rad(lat(i))))；
Wherein, lat (i) represents that Active Set list branch i covers center latitude, lat0 represents base station latitude, and r represents Active Set list branch covering radius, and α represents antenna azimuth, lon (i) represents that Active Set list branch i covers center latitude, long0 represents base station longitude, and angle conversion is become radian by function rad () expression, and 111 × 1000 represent 1/360th of terrestrial equator girths, unit rice, i.e. 111 kms.
Step 3) all branches covering center longitude in Active Set to be averaged, this mean value is as the release center of user radio ticket.Such as can adopt following formulae discovery:
Latitude＝SUM(lat(i))/N；
Longitude＝SUM(lon(i))/N；
Wherein, Latitude represents the latitude at release center, Longitude represents the longitude at release center, lat (i) represents that Active Set list branch i covers center latitude, lon (i) represents that Active Set list branch i covers center latitude, N represents Active Set pilot tone (i.e. sector) quantity, and function SUM () represents summation operation.
With reference to the example at the determination release center shown in figure 3, hypothesis activation concentrates You Lianggedan branch, utilize step 1) calculate radius r 1, the r2 of each branch respectively, then step 2 is utilized) calculate each branch covering center longitude (lat1, lon1), (lat2, lon2), finally step 3 is utilized) averaging to Liang Ge branch covering center longitude obtains the longitude and latitude (Latitude, Longitude) at release center.
