Embodiment
In order to make purpose of the present invention, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the present invention, is not intended to limit the present invention.
Referring to Fig. 1, the screening high-speed mobile cellphone subscriber's that the present invention proposes method specifically may further comprise the steps:
The A/C/E interface of S101: comprehensive monitoring GSM net utilizes the related backfill technology of signaling monitoring system to guarantee the high backfill rate of IMSI that the normal position is upgraded;
S102: the LAC after the position upgraded is made as high ferro private network LAC, to the position of each hour more the LAC that does after the position is upgraded of new record filter, the LAC after the position is upgraded is that the position updating call detail record of non-high ferro private network LAC is deleted;
S103: the minimum, the maximum time difference that calculate respectively high ferro private network LAC;
S104: the minimum time according to described high ferro private network LAC is poor, maximum time difference, judge that time difference table that each IMSI passes in and out each high ferro private network LAC is whether poor and less than or equal to described maximum time difference more than or equal to described minimum time, if so, then be defined as meeting the IMSI of time requirement.
Step S101 further is specially: the normal position by monitoring A interface is updated successfully record, mainly obtains the corresponding relation of IMSI-TMSI-TMSI-IMEI.Position for monitoring C interface access HLR is upgraded, and can obtain the corresponding relation of user MSISDN-IMSI.E interface is the interface between MSC and MSC, by the monitoring E interface, can make whole process be associated in a plurality of MSC and do the IMSI record that the position is upgraded.
If only monitor a certain interface, will cause that critical field IMSI can't obtain correct related backfill in the call detail record that the normal position upgrades.Therefore need comprehensive monitoring A/C/E interface, and for the corresponding relation of learning from different interfaces is shared, the related backfill of many interfaces need to be placed on same related backfill server.Many interfaces are disperseed related backfill or related backfill server is disperseed to dispose the low needs that do not reach subsequent analysis of the related backfill rate of the IMSI that all will cause the normal position to be upgraded.
Position more new business mainly is comprised of normal position renewal, periodic location update and the renewal of IMSI attachment position.And the normal position renewal is the flow process that the present invention needs emphasis to use.Owing to comprising the LAC information after the position is upgraded in the updating call detailed recorded data of position, therefore, can be by this train value being made as high ferro private network LAC as filtercondition, LAC after the position upgraded is that the position updating call detail record of non-high ferro private network LAC is deleted, to alleviate the data volume of trailer record inquiry, improve inquiry velocity.In addition, also can by being the call detail record deletion that periodic location update and IMSI adhere to the position updating type, further reduce the data volume of inquiry.
Through the filter operation of S102, we have obtained the normal position in analyzed zone and have upgraded database of record.Rear recorded information at high ferro private network LAC is upgraded in store relevant IMSI normal position in the database.Order in chronological sequence, search each IMSI in the database in first normal position of each high ferro private network LAC the time value of the initiation time of new record more.If the record that certain IMSI has two sections normal positions to upgrade can obtain by the initiation time of this two segment record occuring the time difference that this twice normal position upgraded.This time difference representative passes in and out the time difference of certain high ferro private network LAC overlay area.By this method, we obtain finally that each high ferro private network LAC(of each IMSI approach enters high ferro private network LAC in the database) time and pass in and out the time difference table of each high ferro private network LAC.To classify by high ferro private network LAC the time difference, add up each time point the number of times that the normal position is upgraded occurs, sorting from less to more just to gather by the time difference at last to obtain distribution shown in Figure 3.From distribution map, can find easily minimum and the maximum of each high ferro private network LAC time difference of turnover.
Therefore minimum, the maximum time difference of the turnover high ferro private network LAC that S103 counts are for all IMSI in the database, and non-high-speed mobile user's IMSI might be mingled with wherein, and the time difference maximum that causes passing in and out each high ferro private network LAC is excessive.For this reason, need to be by by other data the time difference maximum being revised.Here to use high-speed mobile user's translational speed and the distance of turnover high ferro private network LAC approach circuit.Here the high-speed mobile user who mentions is the mobile subscriber who takes the high ferro train.Because high ferro train in the process of moving speed can be limited at a certain speed, so the travel speed of train can be made as definite value.The distance of turnover high ferro private network LAC approach circuit has several scenes:
The first, area boundary A is to the station;
The second, the station is to area boundary B;
Three, area boundary A is to area boundary B.
According to the latitude and longitude of base station at border A, B and station, calculate the distance of above-mentioned three kinds of situations.As molecule, the travel speed of train can calculate the theoretical time value of each high ferro private network LAC of turnover as denominator with the maximum of these three distances.Use this value as the maximum of each high ferro private network LAC of turnover.The turnover minimum value of each high ferro private network LAC and maximum as filtering the more condition of new record of normal position, are carried out secondary filter to each IMSI in the database.If certain IMSI enter high ferro private network LAC:A to the normal position update time that enters high ferro private network LAC:B poor greater than setting the time difference maximum or less than the time difference minimum value, this IMSI is not the high-speed mobile cellphone subscriber that we need to analyze so.Filter the high-speed mobile cellphone subscriber that remaining IMSI need to analyze for us through 2 times.
Referring to Fig. 2, move high-speed railway private network mobile subscriber the present invention will be described as example take Jiangsu.Move as guaranteeing that the user in the high-speed railway normally uses cell phone professional in Jiangsu, and reduce unnecessary signaling consumption, for providing proprietary LAC, the high-speed railway private network arranges and every wireless parameter that service is provided for private network, such as unidirectional switching, and private network traffic distribution strategy etc.Make the mobile subscriber who takes the high-speed railway motor-car in the situation that do not go out private network, the every convenient service of normally using the mobile network to provide.Beijing-Shanghai High-Speed Railway Nanjing section LAC is 20762, and Zhenjiang section LAC is 21187, and Changzhou Section LAC is 21161, and Wuxi Section LAC is 21219.
Consider that the G prefix High Speed Railway Trains that present Beijing-Shanghai High-Speed Railway is used is the CRH380 vehicle, maximum speed per hour per hour can reach 380 kilometers.Domestic bus stop has southern station, Nanjing, station, Zhenjiang, station, Changzhou and Wuxi station in Jiangsu, and wherein the southern station, Nanjing is must the stop, and station, Zhenjiang, station, Changzhou, Wuxi station are for selecting the stop.At present, the Ministry of Railways stipulate bullet train F-Zero on this circuit be limited in 310 kilometers per hour below.Therefore, statistics passes in and out 4 rapid transit private network LAC district's time differences in the distribution of whole day peak hour section, referring to Fig. 3.By time difference maximum correction, the minimum running time that obtains between two stations is Tmin=3 minute, and the longest running time is Tmax=30 minute.
Jiangsu is being moved A(or Mc interface)/ basis that C/E interface Real Time Monitoring gathers on, utilize the related backfill technology of signaling monitoring system, the IMSI backfill rate that guarantees to upgrade the normal position is more than 97%.Because high-speed railway private network antenna for base station has been done special adjustment, except main covering high-speed railway, also takes into account the covering of other neighboring areas.Therefore, near the resident who lives the high-speed railway private network is easy to enter into the high-speed railway private network from peripheral network when doing normal position renewal or switching.In order from the high-speed railway private network, to get rid of non-high-speed railway cellphone subscriber, with normal position LAC before the new technological process Position Updating more, CI before the position is upgraded, CI appeared at LAC and the CI scope of high-speed railway private network regulation after LAC and position were upgraded after the position was upgraded, and meet minimum Tmin between two stations to entering LAC:A to the time difference that enters LAC:B, maximum travel time T max condition (between two stations minimum Tmin＜time difference＜maximum travel time T max) the normal position more new record extract, and press IMSI grouping, finally form the normal position new record section more take IMSI as unit.By time-sequencing, just can obtain take certain IMSI as unit, take high-speed railway motor-car passenger's detailed travel path record.Comprise in the travel path passenger's approach station the concrete moment, stand between spended time, approach station number and travel direction.
As replenishing of high-speed mobile user screening technique, will occur in calling in the high-speed railway private network and handover event as one of high-speed railway mobile subscriber criterion.
Relate to switching type and be divided into two classes:
The first, switch in Different L AC district.When certain mobile subscriber makes a call until LAC district B from LAC district A, normal position more new technological process will be delayed.When the end of calling at LAC district B, normal position more new technological process will be reactivated.
The second, identical LAC district, switch different CI residential quarter.This type of switching flow will be subdivided into switch in the BSC with identical MSC different B SC between switch.Because the handover event time is shorter, and occurs in the LAC district, therefore can not exert an influence to normal position update flow.
Relate to handoff scenario as follows:
The first, business is initiated LAC and CI large net beyond private network, and professional termination LAC and CI are at private network.Need to pay close attention to whether the professional LAC of initiation and CI are the exclusive LAC in station and CI.The station, need to observe follow-up normal position more new technological process whether at private network.At private network, explanation is the high-speed railway mobile subscriber.Not at private network, abandon searching.Not the station, directly abandon searching.
The second, business is initiated LAC and CI, and professional termination LAC and CI are all at private network.Observe follow-up normal position more new technological process whether at private network.At private network, explanation is the high-speed railway mobile subscriber.Not at private network, abandon searching.
