Can be delivered. In general, it can be presumed that information that is highly interested by many users is also of interest to users who have entered the region. For this reason, according to the present invention, it is possible to distribute information that is estimated to be of interest to the user among the information on the region including the position where the user is present.

  Hereinafter, an embodiment of a regional information distribution system according to the present invention will be described. FIG. 1 is a schematic diagram of a regional information distribution system according to an embodiment.

  As shown in FIG. 1, the regional information distribution system according to the embodiment includes a host station 10 that distributes regional information, a mobile phone 20 that each user possesses, and a fixed receiver 30 that is provided in each door in the region. Composed. Among these, the mobile phone 20 and the fixed receiver 30 are information terminals.

  The host station 10 stores a region information database (region information storage means) 11 that stores region information within a predetermined region, an access record database 12 that stores access records to the region information database 11, and an access record database 12. The access frequency database (access frequency storage means) 13 for storing the access frequency to each area information stored in the area information database 11 with reference to the stored access records, and the area information is wirelessly transmitted to each information terminal. A wireless distribution device (wireless distribution means) 14 capable of distribution, a control device (control means) 15 for controlling these databases and distribution devices, and a management personal computer 16 for managing the regional information database 11 are provided. Yes.

  The region information database 11 includes a plurality of records each storing region information unique to the region and the community constituting the region, such as local government information, community information, and weather information. Field for recording heading information, detailed information, and information ID.

  The access record database 12 records information related to the access when the user accesses the detailed information of the information stored in the regional information database 11 via the mobile phone 20 or the fixed receiver 30. One record is added to. Each record includes a field for recording a user ID for identifying the accessed user, an information ID for specifying the accessed area information, and an access time during which the access has been continued. The user ID includes, for example, the SIM card ID of the mobile phone 20, identification information assigned to the fixed receiver 30, and the like.

  The access frequency database 13 has one record for each area information, and each record stores an information ID for specifying the area information, the total number of accesses for the area information, and the total access time for the area information. Field to be included. By counting the contents of the access record database 12 at regular time intervals, records in the access frequency database 13 are added or existing records are updated.

  The wireless distribution device 14 exchanges information between the mobile phone 20 and the fixed receiver 30 via wireless communication.

  The control device 15 distributes the heading of the regional information stored in the regional information database 11 to the mobile phone 20 or the fixed receiver 30 in the region, and there is a request for detailed information from the mobile phone 20 or the fixed receiver 30. The detailed information corresponding to the requested headline is distributed. Then, the detailed information request is regarded as an access, and the access is recorded in the access record database 12, and the contents of the record are totaled at a predetermined time interval and registered in the access history database 13.

  In addition, when the mobile phone 20 enters a predetermined area covered by the host station 10, the control device 15 refers to the access frequency database 13 to select regional information having a high access frequency, and the wireless distribution device 14. Is controlled, and at least a part of the area information selected for the mobile phone 20, in this example, a headline is distributed. When there is a request for detailed information from the mobile phone, the details of the regional information are read from the regional information database 11 and distributed, and are recorded in the access record database 12 so that they are stored in the access frequency database 13. The access frequency related to the regional information is updated.

  In this example, the fixed receiver 30 is also configured to be capable of wireless communication, but may be connected by wire. The fixed receiver 30 may be a dedicated terminal or may be realized by installing necessary software in a general-purpose personal computer. Furthermore, in the example of FIG. 1, only one host station is shown, but different host stations may be arranged in different regions, or a plurality of host stations may be prepared in the same region. As a wireless standard, WiMAX (abbreviation for worldwide interoperability for microwave access) may be used.

  Next, the operation of the regional information distribution system of the embodiment configured as described above will be described with reference to the flowcharts of FIGS. FIG. 2 shows an overview of the access recording / aggregation process, and FIG. 3 shows an overview of the regional information distribution process.

  During operation of the regional information distribution system, the control device 15 repeatedly executes the access recording / aggregation process shown in FIG. In this process, it is determined whether or not any user has accessed the detailed information in the regional information database 11 (S001). If there is an access (S001, YES), the access record database 12 is accessed, That is, the user ID, information ID, and access time are registered (S002). As a result, a new record is added to the access record database 12 every time there is an access. If there is no access (S001, NO), S002 is skipped.

  Subsequently, the control device 15 determines whether or not the total time has been reached (S003). For example, the total time is set twice a day at 10 am and 6 pm. At any one of these times (S003, YES), the control device 15 totals the contents of the access record database 12 and registers them in the access frequency database 13 (S004). That is, the number of accesses is totaled for each area information, and the access time is totaled. If the record of the area information already exists in the access frequency database 13, the total number of accesses and the access time are updated by overwriting the corresponding field values of the existing record, and if no record exists Generate a new record and store the value in each field. As a result, the contents of the access frequency database 13 are updated twice a day. If it is not the total time (S003, NO), S004 is skipped.

  Subsequently, the control device 15 determines whether or not the clear time has been reached (S005). For example, the clear time is set once a week and every Monday at 6 am. When the clear time comes (S005, YES), the control device 15 clears all the contents of the access record database 12 and the access history database 13 (S006). As a result, the access record and history are cleared once a week, and recording is newly started from zero. If it is not the clear time (S005, NO), S006 is skipped and the process is terminated.

  Next, processing when the user carries the mobile phone 20 and enters the cover area from outside the cover area of the host station 10 will be described with reference to FIG. Whether the mobile phone 20 has entered the cover area may be determined by the host station 10 that has received the radio wave from the mobile phone 20 or may be determined by the mobile phone 20 having a GPS function. Also good.

  When the mobile phone 20 enters the cover area, the control device 15 accesses the access record database 12 (S101) and determines whether there is an access record (S102). When there is an access record (S102, YES), the control device 15 accesses the access frequency database 13 (S103), and determines whether or not there are a predetermined number or more of records having a predetermined frequency or more (S104). For example, it is determined whether or not there are 5 or more records having 10 or more accesses. When this requirement is satisfied (S104, YES), the control device 15 distributes a predetermined number of high-frequency information headings to the mobile phone 20 in the cover area (S105). Specifically, the control device 15 extracts, for example, information IDs of five area information having 10 or more accesses from the access frequency database 13 and reads heading information from the area information database 11 using this information ID as a key. Deliver this.

  If there is no access record in the access record database 12 immediately after clearing (S102, NO), among the information recorded in the regional information database 11, a predetermined number, for example, five latest information headings are entered in the cover area. Distributed to the mobile phone 20 (S106).

  If the access record database 12 has an access record (S102, YES) but the access frequency database 13 does not have a predetermined number of records with a predetermined frequency or more (S104, NO), the time since clearing is short (S104, NO). A headline of information (in this example, information having an access count of 10 or more) and a headline of latest information that is less than the predetermined number are distributed to the mobile phone 20 in the cover area (S107). For example, if there are only two records in the access frequency database 13 with the number of accesses of 10 or more, the heading of the area information corresponding to these 2 records and the latest area information for 3 cases less than the predetermined number, here 5 To the mobile phone.

  Regardless of which header is distributed, it is determined whether or not the user of the distributed mobile phone 20 has accessed detailed information regarding the distributed header (S108). When the detailed information is accessed, the control device 15 reads the accessed detailed information from the regional information database 11 and distributes it to the requesting mobile phone. Further, the access by the mobile phone is also counted as the access in S001 of FIG. 2 and recorded in the access record database 12.

  As described above, according to the regional information distribution system of the embodiment, by distributing information that is frequently accessed within one week for the local user to the mobile phone 20 of the user who has entered the cover area of the host station 10, The user who has entered from can also know the information that is currently interested in the area, and can distribute information that is estimated to be of interest to the user among the information in the area.

  In the above embodiment, all access records are cleared once a week. However, the date and time information is given to each access information, and is cleared when one week has passed for each access record. You may do it. In this case, the access record for the latest one week always remains, and the process of S102 in FIG. 3 is not necessary.
