Description

  The present invention relates to a method for providing crime information about a region where a mobile communication terminal exists to the mobile communication terminal through the mobile communication network.

  If you are going to an unfamiliar area, whether domestic or overseas, due to the recent increase in crime rate, you should know the security situation and crime occurrence status in the destination area before you go out, that is, crime information There is a need. Also, even if you go to a familiar area, the risk level of the area changes from moment to moment so that suspects of violent crimes enter from other areas and hide, so again, the crime information of that area You need to know before you go out. Furthermore, even in the area where you live, there is no guarantee that the risk is unchanged, so it is desirable to know the crime information in that area.

  For this reason, those who need to know crime information in each region must obtain the necessary information from television and radio news and newspaper articles that are unilaterally distributed. Alternatively, you must actively access Internet sites that disclose criminal information such as the Metropolitan Police Department's website to detect the necessary information.

  However, since the crime information that can be acquired through such media is enormous, it is difficult to accurately sort out information related to the destination area. In particular, there are many crimes that occur in the immediate vicinity (such as snatching and passing demons), so there is a possibility of overlooking what occurred in the destination area. Moreover, since these media are usually accessed indoors, it is almost impossible to know when new crime information is generated while moving to the destination area.

  The present invention has been devised in view of such problems, and the problem is that the crime information related to the area where the user is actually present can be displayed on the mobile communication terminal held by the user. It is to provide a crime information providing system using a communication network.

The crime information providing system of the present invention, for a plurality of crimes that occurred in the past in the service providing area, database means for storing crime information indicating the date and time of occurrence of the crime, the place of occurrence, and the contents of the crime, and the service provision Terminal position detecting means for detecting an area where the mobile terminal is present among a plurality of areas obtained by dividing the area into a plurality of areas, and the crime information in which the occurrence location is included in the area detected by the terminal position detecting means Read from the database means, and the crime information reading means And editing means for editing the sin information, and transmission means for transmitting the crime information edited by the editing means to the mobile terminal through the mobile communication network, characterized by comprising.

  If comprised in this way, when the user with a mobile terminal enters any area in a service provision area, a terminal position detection means will detect that the mobile terminal exists in the area. Then, the crime information reading means reads the crime information whose location is in the area from the database means. One or more read crime information is edited into a single sentence by the editing means, and the edited crime information is transmitted to the mobile terminal by the transmission means.

  In the database means, a plurality of crime information may be stored in a state classified for each region including a crime occurrence place, or a plurality of crime information may be stored without being classified. In the former case, the crime information for each classified area may be stored in a database prepared for each area. The database may be a publicly-known bulletin board database, and topics in which each crime information is described on the bulletin board.

  If the mobile terminal has a GPS function, the terminal position detection means is present based on the position information detected by the mobile terminal using the GPS function and transmitted through the mobile communication network. What is necessary is just to detect an area. Even if the mobile terminal does not have a GPS (Grobal Positioning System) function, the mobile terminal can be a mobile phone, a car phone or a PHS (Personal Phone System) phone (a PDA [Personal Digital It is sufficient to detect an area where a ground station of a mobile telephone network directly connected to the mobile terminal is present.

  The crime information reading means may read from the database means all crime information whose location is the occurrence location, but may read only crime information whose occurrence date is within a certain past period, Only crime information that has not been read in the past may be read for transmission to the mobile terminal.

  When the crime information reading means reads a plurality of crime information, the editing means may aggregate the crime contents for each type of crime contents, or edit the crime contents by collecting them into a single sentence. Also good.

  The transmission means may transmit the crime information edited into a single text by the editing means to the mobile terminal in the form of an e-mail or may be transmitted as Web content.

  According to the crime information providing system using the mobile communication network according to the present invention configured as described above, the crime information related to the area where the user is present can be displayed on the mobile communication terminal held by the user.

  At the processing start timing, the server (database update application program 121) requests crime information registered in the crime occurrence map database 40 after the previous execution to the crime occurrence information server 4 via the Internet N. (S11).

  In response to this request, when the crime occurrence information server 4 responds with one or more crime information, the server (database update application program 121) sends the received crime information to the occurrence location (latitude / longitude). Based on which management target area (A area, B area, C area) is included, classification is made for each management target area (S12).

  Then, the server (database update application program 121) registers the crime information classified for each management target area in the crime occurrence databases 132 to 135 corresponding to each management target area (S13).

<Distribution of crime information to mobile phones>
FIG. 7 is a flowchart showing “processing” for distributing crime information about the management target area to which the current position of the mobile phone 3 belongs to the mobile phone 3, and the first half (S 21) is the CPU 30 of the mobile phone 3. The second half (S31 to S34) shows the processing executed by the server (GPS information transfer search application program 123, mail creation / transmission application program 124).

  This process starts every time the GPS unit 35 periodically acquires position information (latitude / longitude) and stores it in the memory 34 in the mobile phone 3 as described above. After the start, the mobile phone 3 transmits the position information (latitude / longitude) stored in the memory 34 to the server (GPS information transfer search application program 123) (S21).

  The server (GPS information transfer search application program 123) that has received the position information (latitude / longitude) selects the management target area (A area, B area, C area) including the transmitted position information (latitude / longitude). Detected (corresponding to terminal position detecting means), and reads all unread crime information regarding the requesting mobile phone 3 from the crime occurrence databases 132 to 134 corresponding to the detected area (corresponding to crime information reading means). Then, all the read crime information is classified for each generation type number, and the number of cases for each generation type number is totaled (corresponding to editing means) (S31).

  Next, the server (mail creation / transmission application program 124) checks the number of all crime information read in S31. If the number of cases is zero, the server (mail creation / transmission application program 124) ends the process. On the other hand, if the number of cases is one or more, the server (email creation / transmission application program 124), from the word-of-mouth information data table of the real-time crime occurrence information database 135, the location information (from the mobile phone 3) The occurrence location (latitude / longitude) is included in the same management target area as the latitude / longitude), and all unread crime information regarding the requesting mobile phone 3 is read (corresponding to crime information reading means) (S33).

  Subsequently, the server (email creating / sending application program 124) generates an e-mail having the contents as shown in FIG. 8 based on the number of occurrence type numbers counted in S31 (corresponding to an editing unit). . Further, when one or more crime information is read in S33, the server (mail creation / transmission application program 124) lists the word-of-mouth information of all read crime information as shown in FIG. E-mail is generated (equivalent to editing means). Then, the server (mail creation / transmission application program 124) matches all the generated electronic mails with the electronic data registered in the user registration database 131 in association with the requesting mobile phone 3 (identification information of the requesting mobile phone 3). It is transmitted to the mail address (corresponding to a transmission means) (S34). The mobile phone 3 that has received these e-mails displays the contents of the e-mails on the display 32.

(Usage example)

Then, when the GPS unit 35 of the mobile phone 3 first acquires the position information (latitude / longitude) after entering the α town, the processing of FIG. 7 is executed, and the e-mail listing the word-of-mouth information is sent to the mobile phone 3. Has been sent to. In order to get to restaurant X from Mr. A's current location, he must pass either B, C or D, but according to the word-of-mouth information listed in the e-mail, there have been frequent snatching on B. It was said that a demon appeared on D Street last week. Therefore, Mr. A selected street C and headed for restaurant X.

<Usage example 2>
Mr. A is driving to the tourist spot β. Then, when the GPS unit 35 of the mobile phone 3 first acquires the position information (latitude / longitude) after entering the management target area including the tourist spot β, the processing of FIG. An e-mail listing the number of cases has been sent to the mobile phone 3. Sightseeing area β has parking lot B facing the street and parking lot C in the back of the street. At first glance, parking lot C seemed to be vacant and it seemed easier to park the car. According to the e-mail, there were many on-vehicle targets. Therefore, Mr. A stopped parking at parking lot C and selected parking lot B.

(Function and effect)
According to the present embodiment configured as described above, each time the GPS unit 35 of the mobile phone 3 acquires the position information (latitude / longitude), the position information (latitude / longitude) is transmitted to the server device 1. Unread crime information for the mobile phone 3 is read from the crime occurrence databases 132 to 134 for the management target area including the position (latitude / longitude), and an e-mail indicating the content is transmitted to the mobile phone 3. . At the same time, crime information whose location (latitude / longitude) is included in the same management target area as the location (latitude / longitude) is read from the real-time crime occurrence information database 135, and an e-mail indicating the content is sent to the mobile phone 3 is transmitted.

  Therefore, when the service user enters the other management target area from the management target area holding the mobile phone 3, the GPS unit 35 first acquires the position information (latitude / longitude) at that time. An e-mail that summarizes crime information about crimes that occurred in the managed area since the mobile phone 3 left the last managed area (may be limited to those that occurred in a certain period in the past) It is transmitted to the mobile phone 3. In addition, even when the service provider stays in the management target area, when crime information about a crime that has newly occurred in the management target area is registered in the crime occurrence databases 132 to 135, the GPS unit is first displayed thereafter. When the position information (latitude / longitude) is acquired by 35, an electronic mail indicating the crime information is transmitted to the mobile phone 3.

  As described above, according to the present embodiment, the service user can grasp the crime information about the area where the user is present without almost omission without actively collecting the crime information. Therefore, even if the service user can avoid or cannot avoid the danger, he / she can be prepared for the danger.

(Modification)
In this actual child form, the position information is acquired by the GPS 35 provided in the mobile phone 3 itself. However, the position information may be acquired as the position of the ground station that is directly wirelessly connected to the mobile phone 3. .

  In addition to the items shown in FIGS. 8 and 9, the e-mail may describe the crime occurrence frequency, crime situation, location of the nearest police station, etc. in the management target area.
