The function of instructing the processing system 40 (which constitutes a main part of the condition specifying means of the present invention) and the mobile terminal 10 of the related parties collected and recorded on the telephone company side processing system 40 side based on the search condition It has a function of requesting information disclosure for owner information and performing the information disclosure. Basically, for information provision from the telephone company processing system 40, an application is made after information collection and a recording device is disclosed. However, depending on the contents of the incident, the information is notified to the output screen of the display unit 53 of the police control terminal 53 in real time while the information is collected on the telephone company processing system 40 side.

  In the present embodiment, the database 55 collects and records information such as a person who has caused a car accident in the past, a speed violation person, a drunk driving violation person, and the like in advance. For example, in the case of a hit-and-run incident, after the information of the mobile terminal 10 to be searched is recorded, the database 55 is collated, and when there is a corresponding person on the database 55, the output screen of the display unit 53 is marked. Displayed information.

  Next, a case will be described in which a search is performed using the above-described target person observation system using the escape means (moving means) of the perpetrator at the time of emergency notification as a search condition.

  Here, the search condition is basically the mobile terminal 10 that leaves at an abnormal speed according to the escape means of the perpetrator. Since the speed is different between when you run away by car and motorcycle and when you run away by bicycle or run, statistics are taken in advance for each speed, measurement range, and measurement time, and common sense values for each crime (case content) (Optimum value) is calculated and set at the start of measurement. This information is stored in the database 55 of the police-side control terminal 50 on a portable terminal basis and used for collation.

  First, in the case of crimes such as running away using cars as escape means, bank robberies, kidnappings, etc., the speeds of cars and motorcycles are used as search conditions. First, the owner information (portable terminal number, etc.) and location information of the mobile terminal 10 that exists for a radius of several kilometers (an average distance based on the escape time) centered on the crime scene (sighting site). Collect all. After a certain amount of time (set an average time: minutes in the case of a car), it is considered that the owner information and position information of the mobile terminal 10 existing within a radius of several kilometers are collected again and moved by car. The category mobile terminal 10 is selected. Do this several times. In particular, the mobile terminal 10 that leaves the crime scene is marked at an abnormal speed. In the case of bank robbery, if it is possible to put the mobile terminal 10 into the perpetrator's bag etc., or in the case of kidnapping, the mobile terminal number of the kidnapped person can be entered as an option, the search target is narrowed down. It is done.

  Further, in the case of crimes such as theft and molesting using a bicycle as an escape means for the perpetrator, the speed of the bicycle is used as a search condition. First, all the owner information and location information of existing mobile terminals are collected for a radius of several hundred meters (an average distance based on the escape time) centering on the crime scene (sighting scene). After a certain amount of time (average time is set: in the case of a bicycle, in seconds), the owner information and location information of the mobile terminal 10 existing at a radius of several thousand meters are collected again and considered to be traveling by bicycle. A mobile terminal 19 in a certain category is selected. Do this several times. In particular, the mobile terminal 10 that leaves the crime scene is marked at an abnormal speed.

  Next, the overall operation of the present embodiment will be described.

  In FIG. 3, incidents such as crimes using cars such as running away, bank robbery, kidnapping, etc., and crimes using bicycles such as theft and molesting occurred (step A11), and witnesses (reporters) Under the control of the control unit 11, “110” is input by the operation unit 13, and an emergency call is issued via the base station 20 via the communication unit 12. This emergency call is sent to the police control terminal 40 via the network 30 and the telephone company processing system 40. At that time, details of the incident accident witnessed by the whistleblower and its occurrence time are communicated to the police by a call between the whistleblower and the police (step A12).

  Next, on the police side control terminal 50 side, under the control of the control unit 51, the search condition (incident case) set in advance on the screen of the display unit 53 according to the content of the case incident that has been communicated, the time of occurrence, etc. The optimum search condition is input or selected from the operation unit 52 from among the contents, escape means, time of occurrence, etc., and the input search condition is instructed to the telephone company processing system 40 via the communication unit 54 (step) A13).

  Next, when the telephone company side processing system 40 inputs the search condition instructed from the police side control terminal 50 via the communication unit 42 under the control of the control unit 41, the telephone company side processing system 40 takes this as an opportunity via the network 30. Then, the owner information (portable terminal number, etc.) and location information (GPS positioning information) of the reporter's mobile terminal 10 are collected (step A14), and the owner information of the mobile terminal 10 existing in the peripheral area of the report location (Mobile terminal number etc.) and location information (GPS positioning information etc.) are collected (step A15).

  Next, under the control of the control unit 41, the telephone company processing system 40 observes the movement status from the location information of the mobile terminal 10 for each time according to the search condition, and determines a plurality of important information according to the movement status. The mobile terminal 10 to be observed is selected (narrowed down), and owner information (mobile terminal number, etc.) and position information (GPS positioning information, etc.) of the mobile terminal 10 are collected and recorded in the recording device 43 (step A16). ).

  For example, in the case of a hit-and-run case, the police who received a report from the victim or witness at the place after the hit-and-run crime or input the search condition such as the case contents to the telephone company processing system 40 . The telephone company side processing system 40 collects the location information of the reporter and, according to the input search conditions, considers the time after the incident and the speed of the car, and the mobile number existing in the area (wide area) near the site. collect. Measure for a certain time, and as time passes, narrow down the mobile terminal number that meets the conditions (such as being away from the site at a tremendous speed) and record it until it stops for a certain time.

  In addition, in the case of a crime by a demon, if the devil is attacked, the police who have received a report from the victim / witness enter the search conditions such as the case contents into the telephone company processing system 40 and give instructions. . The telephone company side processing system 40 collects the location information of the reporter and, according to the input search conditions, takes into account the time after the incident and the escape method, and the mobile number existing in the area (narrow range) near the site. collect. The measurement is performed for a certain time, and as time passes, the mobile phone number that matches the search condition is narrowed down and recorded for a certain time until it stops.

  When the movement of the mobile terminals 10 of all the observation subjects is stopped (step A17), the telephone company processing system 40 confirms the stop and ends the recording (step A18).

  Thereafter, the police-side control terminal 50 sends a disclosure request for the collected information on the mobile terminal 10 to be observed to the telephone company-side processing system 40 via the communication unit 54 under the control of the control unit 51 (step A19). ). Thereby, the telephone company side processing system 40 sends the collected owner information and position information of the mobile terminal 10 to the police side control terminal 50 via the communication unit 42, and the information is disclosed (step A20). As a result, on the police control terminal 50 side, the owner information and position information of the mobile terminal 10 to be observed are confirmed on the screen of the display unit 53.

  Next, a search and recording processing sequence by the telephone company processing system 40 will be described with reference to FIGS. Here, it is assumed that the car is running away.

  4 and 5, first, the police control terminal 50 inputs or selects a search condition from the output screen of the display unit 53. Here, as shown in FIG. 6, it is assumed that the following search condition is input or selected.

1) Case details (incidents that occurred) C1: Pulling away 2) Escape means (moving means) C2: Automobile (if the escape means is an automobile)
3) Occurrence time C3: Incident occurrence time 4) Search (ON: Perform related party search, OFF: Do not perform related party search) C4: ON
5) Number of re-searches (when re-search target exists, how many times re-search is performed) C5: None (until there are no search targets)
Then, the telephone company processing system 40 determines whether or not the search C4 is ON based on the input search condition (FIG. 4: Step St11). As a result, when the search C4 is ON, the incident occurrence position is recorded (FIG. 4: step St12). On the other hand, if the search is OFF, the process ends.

  Next, the telephone company processing system 40 determines what the case content C1 is based on the input search condition (FIG. 4: step St13). As a result, in cases other than pulling away, other processing is performed (FIG. 4: step St15). On the other hand, in the case of pulling away, it is determined what the escape means C2 is based on the input search condition (FIG. 4: step St14). As a result, in the case other than the car, other processing is performed (FIG. 4: Step St17). On the other hand, in the case of a car, the search target range is determined (FIG. 4: step St16).

  Here, the search target range when the escape means is a car will be described. For example, if you use an automobile and escape at 100 km / h, the speed is 1.7 km / min. Also, if you escape at 60 km / h, the speed is 1.0 km / min. Therefore, when 10 minutes have elapsed since the incident occurrence time, for example, a radius of 17 km is set as the target range of the first related party search from the accident occurrence location.

  In the subsequent processing, the search interval is set to 5 minutes, and data for the search interval × 2 times is first acquired. A car that traveled at 100 km / h would have moved 8.5 km in 5 minutes. On the other hand, an automobile that has moved at 60 km / h has moved 5 km in 5 minutes. As a result of acquiring the data for the second time, a car that has moved more than 5 km is re-searched with either data. Thereafter, the search and recording are performed until the number of re-searches C5 is completed or until the stop of the car that is the target of the re-search is confirmed.

  That is, the telephone company side processing system 40 records the owner information and position information of the search target terminal 10 existing in the search target range (FIG. 4: step St18), and acquires the first data 5 Waiting for a search interval of minutes (FIG. 4: step St19), the searchable mobile terminal 10 is searched again (FIG. 4: step St20), and the owner information and position information of the mobile terminal 10 are recorded (FIG. 4: Step St21). Subsequently, in order to acquire the second data, a search interval of 5 minutes is waited (FIG. 5: Step St22), the searchable mobile terminal 10 is searched again (FIG. 5: Step St23), and the mobile terminal 10 is owned. Person information and position information are recorded (FIG. 5: step St24).

  Then, the telephone company side processing system 40 determines whether or not there is a mobile terminal 10 to be re-searched based on whether or not it has moved more than 5 km from the data for two times (FIG. 5: step St25). As a result, if there is no mobile terminal 10 to be searched again, the process is terminated. On the other hand, if there is a mobile terminal 10 to be re-searched, it is determined whether or not the number of re-searches C5 based on the input search condition has ended (FIG. 5: Step St26). As a result, when the number of re-searches C5 ends, the process ends. On the other hand, when the number of re-searches C5 has not ended, the search interval for 5 minutes is again waited (FIG. 5: Step St27), the search-target mobile terminal 10 is searched again (FIG. 5: Step St28), and the mobile terminal Ten owner information and position information are recorded (FIG. 5: step St29).

  Next, the telephone company processing system 40 determines whether there is a terminal that has not been stopped (FIG. 5: step St30). As a result, when there is a mobile terminal 10 that has not been stopped, the process returns to step St26 and the same processing is repeated. On the other hand, when there is no portable terminal 10 that has not been stopped, the process is terminated.

  7 to 14 schematically show the above operation by superimposing on the above-described FIG.
