It is preferable that the display of distribution information can be switched freely).

Through the Wi-Fi spot 102 to which the user can be connected from his/her current position, the user selects the desired information registered in the user information management unit 213 in advance from among the information scheduled to be delivered by the Wi-Fi spot 102. , receives information assumed to match or be necessary for the purpose information of the current route search. The method of information distribution includes a method in which the information itself is directly distributed from the management center 200 to the mobile station 106, and a method in which only a notification is distributed from the management center 200 to the mobile station 106, and from the mobile station 106 side to the management center 200. One of the methods of going to get the information is conceivable.

The route search system of Example 1 can be summarized as follows.

A wireless communication system comprising a plurality of wireless base stations 104, a management center 200 including a database server 210, a GPS satellite 101, a plurality of mobile stations 106, and a Wi-Fi router 102 installed at each location. 100 route search system. The radio base station 104 has a communication area 105 in which communication is possible, and the mobile station 106 located within the communication area 105 and the radio base station 104 can communicate with each other. The mobile station 106 receives position information from the GPS satellites 101 and can obtain the position information (latitude and longitude) of the mobile station 106. The obtained position information is periodically sent to the management center 200 through the radio base station 104. Sent. The management center 200 collects location information of mobile stations 106 located within the communication area 105 through each of the plurality of wireless base stations 104 . The position information of the place where the Wi-Fi router 102 is installed or the communicable range 103 of the Wi-Fi router 102 is registered in the database server 210, and information to be transmitted in advance at the installation point of the Wi-Fi router 102 is stored in the database server. Register with 210. Furthermore, in the management center 200, a starting point and a destination are designated, a purpose within the range of action is designated, and a route search is performed via the installation location of the Wi-Fi router 102 related to the purpose. When connecting to the Wi-Fi router 102 at each location, the mobile station 106 receives information that matches the purpose and preference of the user from among transmission information registered for each Wi-Fi router 102 .

This system can be used in the following ways.

(1) Set a start point and an end point, search for a route passing through points (Wi-Fi spots 102) that meet the purpose between them, connect to the Wi-Fi spots 102 at each waypoint, and obtain information for each point. Follow the route to the end point while obtaining

(2) Set the area you want to tour, search for a route from the starting point (or current location) to the point (Wi-Fi spot 102) that matches your purpose within the set area, and connect to the Wi-Fi spot 102 at each waypoint. Connect and trace the route to the end point while obtaining information for each point.

(3) Set the area you want to tour and search for a route from the starting point (or current location) via a point (Wi-Fi spot 102) that matches your purpose within the set area, but do not disclose all route information, The next point to go to is displayed to guide the user. When the target point is reached, the next point is displayed to guide the user. While repeating this, the user is guided to the final point. In other words, without disclosing all the route information, the user is guided by displaying up to the next destination point, and when the destination point is reached, the next point is displayed on the screen to guide the user. While repeating, guide the user to the final point. When displaying the entire route to the final destination, it is difficult to see the detailed information between points, so by expanding or displaying the details from the current point to the next destination point, the user's convenience can be improved. .

(4) In the method of use (3) above, search up to candidates for points to pass through when searching for a route. Based on the information on the current location and the degree of congestion at each waypoint, a route to the next destination is searched and notified to the user. From the condition, while repeating the search for the route to the next destination point, it goes around the set area. In other words, when searching for a route, it searches up to candidate points to go through, searches for a route to the next destination based on the information on the current location and the congestion status of each waypoint, and when it reaches the destination, it searches for the current location. information and the degree of congestion at each waypoint to further search for a route to the next destination point. The congestion status at each waypoint may be detected via the Wi-Fi router or base station radio equipment at each point.

(5) The user sets a start point and an end point, and searches for a route passing through a point (Wi-Fi spot 102) matching the purpose in that section (within the area). On the service provider side, when searching for a route, include points that the user wants to stop by. All the route information is not disclosed, the user is guided to the next destination point, and the user does not only connect to the Wi-Fi spot 102 at the destination point, but also goes to that place in advance. By performing a predetermined action (a specific action: for example, reading a two-dimensional barcode at the site with a mobile phone terminal or smart phone and indicating that the user has stopped by), the next destination point is presented to the user. For example, if you are active at one destination, you can search for a route to relax and relax at the next destination (such as visiting a footbath, hot spring, or coffee shop).

(6) When searching for a route, weighting the waypoints when searching for waypoints that match the information of the user's preferences within the area A waypoint is selected based on whether the location is highly evaluated by users, the number of users who stop by is large, etc.). In other words, when multiple waypoints are found as a result of a route search, by prioritizing the places you definitely want to visit and the places you want to visit if possible, you can make it more effective in the limited time. can be active in By answering a questionnaire in advance by the user before departure, the user's preferences and wishes can be collected.

According to the route search system of Example 1, the following effects can be obtained.

1) The system user can not only display the route from the departure point to the destination point, but also search for a route according to the user's purpose and conditions.

2) Also, by connecting to the Wi-Fi spot 102 on the route, the mobile station 106 can receive distribution information that matches the purpose and taste of the user.

3) By re-searching the next point to pass through for each waypoint based on the conditions (congestion status) at the time of searching, it is possible to search for the optimum route.

4) The effects as described above can be expected, and compared with the route search system according to the comparative example, route search according to the user's purpose and necessary information can be received.

Next, a radio communication system according to a second embodiment will be explained using FIGS. 7 and 8. FIG. FIG. 7 is a schematic configuration diagram of a wireless communication system according to the second embodiment. FIG. 8 is an example configuration diagram of the management center of FIG.

A wireless communication system 100A shown in FIG. 7 is a vehicle allocation system configured by an AVM (Automatic Vehicle Monitoring) system for vehicle management. The radio communication system 100A of FIG. 7 differs from the radio communication system 100 of FIG. 1 in that a vehicle allocation center 300 having a plurality of vehicle allocation terminals 310 (310-1, 2, . . . ) is provided. .

In the radio communication system 100A, a plurality of mobile stations 106 includes a device for detecting positional information (for example, a navigation device), an operating device for receiving input of various information from crew members, and a radio device for performing radio communication with the radio base station 104. and a wireless device that performs wireless communication with the Wi-Fi spot 102 . Although a dedicated wireless communication terminal may be used as the mobile station 106, various portable terminals such as commercially available mobile phone terminals (for example, smart phones) and tablet terminals having wireless communication functions may be equipped with the above devices. It is also possible to use an application installed with an application for a dispatch system that realizes the function of . Further, in the mobile station 106, the wireless device that communicates with the wireless base station 104, the wireless device that wirelessly communicates with the Wi-Fi spot 102, and the operation device that allows the crew to input movement information etc. may be integrated. It may be configured as a separate device. In the following description, the mobile station 106 is synonymous or nearly synonymous with a vehicle, and the above device as the mobile station 106 is provided in each vehicle.

Each mobile station 106 can receive a signal from the GPS satellite 101 and obtain position information including the position (latitude, longitude) and traveling direction of its own vehicle. The location information obtained by the mobile station 106 is periodically transmitted to the management center 200 together with the movement information of the mobile station 106 (vehicle) through the radio base station 104 having the communication area 105 in which the vehicle is located. The mode of periodically transmitting the position information and the movement information to the management center 200 can be any mode, such as every fixed time, every fixed distance, or a combination of a fixed time and a fixed distance.

Dynamic information refers to information indicating vehicle dynamics, and is input by operating the mobile station 106 by a vehicle crew member (driver). The dynamics of a vehicle include "empty vehicle" indicating that the vehicle is traveling without a customer, "actual vehicle" indicating that the vehicle is traveling with a customer on board, "payment" indicating that the customer is paying the fare, "Pick up" indicating the state of moving (distributing) to the customer's position (pick up destination), "Rest" indicating the state of resting without picking up the customer.

Also, each mobile station 106 accepts an input of the customer's destination area (and point) from the crew and transmits it to the management center 200 when a new customer gets on the vehicle and changes the status to "actual vehicle". In addition, each mobile station 106, when the status of the vehicle is "actual vehicle" but is scheduled to become "empty" soon, each mobile station 106 sends an empty schedule notification indicating that the vehicle status is scheduled to be "vacant". , is transmitted to the management center 200 by the operation of the crew or automatically.

In such an AVM system for taxi dispatch, a customer contacts the dispatch center 300 and informs the operator of the destination to be picked up, for example, the current position information and necessary vehicle information, thereby making a dispatch request. At the dispatch center 300 , an operator operates a dispatch terminal 310 to transmit customer information and necessary vehicle information to the management center 200 . The management center 200 searches for the most suitable vehicle based on the customer's current location information received from the vehicle allocation center 300 and the collected location information of the mobile station 106, and allocates the vehicle to the customer's current location. .

The management center 200 collects location information, movement information, etc. of the mobile stations 106 existing within the communication area 105 through each of the plurality of radio base stations 104, and manages each mobile station 106. FIG. In addition, when the management center 200 receives a vehicle allocation request including the location of the pick-up destination (destination of the vehicle) of the customer who requested the vehicle allocation (and information on the desired vehicle, etc.), the management center 200 receives the location information and movement information of each mobile station 106. Based on this, a vehicle suitable for dispatch is searched (searched) as a candidate for dispatch. After that, the searched candidate vehicles for vehicle allocation are ordered according to a predetermined priority standard, and a vehicle allocation instruction is transmitted to the mobile station 106 of the vehicle selected for vehicle allocation.

The vehicle allocation center 300 transmits a vehicle allocation request to the management center 200 in response to the operation of the vehicle allocation terminal 310 by the operator who received the vehicle allocation request from the customer. After that, when receiving the vehicle allocation candidate vehicle list from the management center 200, the vehicle allocation terminal 310 displays each vehicle of the vehicle allocation candidates on the screen according to the priority, and the vehicle selected by the operator from among them is sent to the management center 200 as the vehicle to be allocated. Then, an instruction to allocate the vehicle to the mobile station 106 of the vehicle is transmitted.

In addition to making a dispatch request to the operator of the dispatch center 300 by telephone, the customer may use the website of a taxi company or an application for dispatch request that is installed in various commercially available mobile terminals (mobile phone terminals and tablet terminals). is used to access the management center 200 through the Internet line, a vehicle allocation request can be made directly to the management center 200 without going through the vehicle allocation center 300 . In this case, the management center 200 automatically selects the vehicle with the highest priority among the candidates for vehicle allocation, and transmits a vehicle allocation instruction to the vehicle.

Here, for example, consider a case where the customer is a tourist and the purpose of the ride is shopping or sightseeing. In this case, for example, on the display screen for setting route search conditions of the mobile station 106, a crew member designates a starting point (current location may be used) and a destination, or an actionable range, and designates a purpose within that action range. do. The purpose is set according to the occasional purpose, such as shopping or sightseeing. After setting, a route search is performed using the route search system of the present disclosure. As a result, the routes RTS, RTT, etc. described with reference to FIGS. 3 and 4 are retrieved and displayed on the display screen. After that, as described in the first embodiment, by traveling the routes RTS and RTT, the purpose of boarding can be achieved and various information can be obtained from the Wi-Fi spot 102 .

The configuration of the management center 200 provided in the wireless communication system 100A will be described with reference to the configuration example shown in FIG. The management center 200 shown in FIG. 8 differs from the management center 200 shown in FIG. 2 in that a vehicle allocation server 400 and a vehicle allocation database server 500 are provided. Note that each component of the management center 200 does not need to exist at the same location, and may be installed on separate networks.

The vehicle allocation database server 500 is a server that manages various data related to the operation of the vehicle allocation system. The vehicle allocation database server 500 includes an area information management unit 501 that stores and manages area information about each area, a vehicle information management unit 502 that stores and manages vehicle information about each vehicle, and an order waiting for vehicle allocation (a vehicle allocation request). and a queue management unit 503 that stores and manages queue information related to.

The area information of each area managed by the area information management unit 501 stores identification information of the area, information indicating the range of the area, information indicating search conditions for vehicles to be dispatched to customers in the area, and the like. . In this example, it is assumed that a taxi company that uses this system divides its business area into several areas in advance and sets area information for each area in the area information management unit 501 . All locations within the business area belong to one of the areas set here. It should be noted that it is also possible to specify and set several areas within the sales area, and to set areas outside of these areas as "other areas" as one area. It is also possible to include areas outside the sales area in the "other areas".

The vehicle information of each vehicle managed by the vehicle information management unit 502 includes identification information of the vehicle, current position information of the vehicle, information indicating the dynamics of the vehicle, and destination area ( and location), the presence or absence of an empty schedule notification, and the like are stored. The data managed by vehicle information management unit 502 is updated as needed through communication with mobile station 106 .

The queue information managed by the queue management unit 503 (hereinafter simply referred to as "queue") was searched according to the order (dispatch request), but no candidate vehicle for dispatch (vehicle suitable for dispatch) was found. In this case, order slips (delivery waiting information) recorded for orders for which customers have agreed to wait for a while are arranged for each area.
