Note that when a rejection signal is transmitted from the mobile station 50 to the vehicle allocation unit 30, the operator who performs vehicle allocation selects another candidate vehicle, and determines the alternative vehicle allocation vehicle through the same processing as described above.
[0022]
Next, a GPS mobile phone 39 having a position detection function added to the mobile phone 3 used in the mobile phone 3 that can be suitably used in the embodiment of the present invention will be described.
[0023]
The GPS mobile phone 39 is obtained by attaching a GPS positioning unit to the mobile phone 3 to measure the position (longitude and latitude) of the current location. The GPS positioning unit is a measuring unit that receives radio waves from a plurality of GPS (Global Positioning System) satellites 51 and calculates the longitude and latitude of the measurement position, and stores a processor (CPU) that performs arithmetic processing, and programs and data. The computer is composed of a memory such as a ROM and a RAM. In this GPS positioning unit, longitude and latitude are measured at a predetermined timing, and the measured positioning longitude and latitude and measurement time are updated and stored in the memory. Then, the cellular phone 39 refers to the longitude and latitude and the measurement time updated and stored in the memory at the transmission start time, and transmits them to the receiving unit 20 as positioning information.
[0024]
Note that the longitude and latitude measured by the GPS positioning unit is treated as a normal value and updated in the memory when measured based on radio waves from four or more GPS satellites (three-dimensional positioning), for example. In other words, the mobile phone with GPS 39 is in a vehicle or building, and the radio waves of some of the GPS satellites are shielded, and the number of satellites that can receive radio waves is three or less (two-dimensional positioning). In such a case, the measured position is not adopted because the accuracy is insufficient, and updating of the positioning information is interrupted. On the other hand, since the customer moves while the position is not measured, the latest position stored in the memory 35 may not represent the position of the customer. Therefore, a measurement time is given to the positioning information (longitude / latitude) transmitted from the mobile phone 39, and it is determined whether the longitude / latitude is valid / invalid at the use stage of the longitude / latitude. That is, only when the elapsed time from the measurement time to the current time is within the effective elapsed time of the GPS positioning information shown in FIG. 2, for example, the stored longitude and latitude are used as the effective value. In addition, the threshold value for determining validity / invalidity shown in FIG. 2 is changed for each time zone, and this is determined based on the mobility tendency of the mobile phone 39 holder for each time zone. For example, at times when the frequency of transportation is high, such as in the daytime or commuting hours, where vehicles often travel, etc. At low time, the valid / invalid judgment threshold is set to a long time. In addition, the validity / invalidity determination processing according to the present embodiment is performed by the control unit 15 (described later with reference to FIG. 3) of the reception unit 20 that receives positioning information (latitude and longitude, measurement time) received from the mobile phone 39. Although it is determined to be performed, the validity / invalidity determination process is performed on the mobile phone 39 side, and if invalid, the positioning information (longitude and latitude, measurement time) may not be transmitted. Further, the threshold value for determining validity / invalidity may be appropriately set by the user according to the situation of the place of use.
[0025]
Next, details of the information processing for determining the vehicle allocation position by the control unit 15 will be described with reference to FIG. FIG. 3 is a flowchart showing processing performed by the control unit 15.
[0026]
This process is started when a customer calls for a vehicle (taxi) dispatch via the public line 10. In step a1, it is determined whether there is a telephone number used by the customer in the electric signal of the incoming call. If there is a telephone number, the process proceeds to step a2, and if there is no telephone number, the telephone using the public telephone 2 or The customer judges that the incoming call is from a telephone whose telephone number is designated as confidential, and proceeds to step a18. In step a2, the telephone number is displayed on the display unit 14 from the electrical signal of the incoming call, and the process proceeds to step a3. In step a3, it is determined whether the telephone number of the phone used by the customer is from the mobile phone 3. If it is from the mobile phone 3, the process proceeds to step a12. Move on to step a4. In step a4, customer information is searched from the database 16 using the telephone number of the incoming call as a key. If registered (customer information exists), the process proceeds to step a5. If not registered (customer information is not present), step a9 is performed. Move on. In step a5, the customer information (phone number, owner name, address, location coordinates (latitude and longitude), past boarding history, etc.) is read from the database 16 in accordance with the phone number and displayed on the display unit 14. The process proceeds to step a6. The longitude and latitude of the displayed customer information indicates the position of the telephone used by the customer, and a detailed map of the dispatch position can be searched. In addition, in the past boarding history of the customer information, the dispatching positions that have been dispatched so far are displayed. In step a6, a detailed map corresponding to the position coordinates (latitude and longitude) of the customer is displayed, and the process proceeds to step a7. In step a7, the dispatch information is confirmed based on the signal that the operator who has accepted is confirmed and input from the operation unit 13, and the process proceeds to step a8. The receiving operator makes a call with the customer while referring to the customer information displayed on the display unit 14 (or the search data retrieved based on the telephone number from the telephone information book) and the detailed map near the dispatch position. Check and enter the location, time, etc. The input vehicle allocation information is displayed on the display unit 13. In step a8, the determined vehicle allocation information is output to the vehicle allocation unit 30 side, and this process is terminated. In step a9, the telephone information book (stored in the database 16) is searched using the telephone number of the incoming call as a key, and the process proceeds to step a10. In step a10, it is determined whether there is data corresponding to the telephone number in the telephone information book. If there is data, the process proceeds to step a11, and if there is no data, the process proceeds to step a24. In step a11, data corresponding to the telephone number (phone number, owner name, address, position coordinates (latitude and longitude), etc.) is retrieved from the telephone information book and displayed, and the process proceeds to step a6. In step a12, if there is positioning information (latitude and longitude, measurement time) as GPS position coordinates (latitude and longitude) in the electrical signal received from the mobile phone 3, processing for obtaining the positioning information is performed, and the process proceeds to step a13. . When the phone used by the customer is the GPS mobile phone 39, this positioning information (longitude and latitude, measurement time) is acquired. In step a13, it is determined whether positioning information has been acquired. If it has been acquired, the process proceeds to step a14, and if not, the process proceeds to step a15. In step a14, it is determined whether the position coordinates (latitude and longitude) of the obtained positioning information are valid or invalid. If valid, the process proceeds to step a6, and if invalid, the process proceeds to step a15. The validity / invalidity determination is performed using data (stored in the database 16) indicating the valid elapsed time of the GPS positioning information as shown in FIG. That is, it is determined whether the elapsed time from the measurement time of the latest positioning information to the present time is within the effective time (threshold value) shown in FIG. If it is within the valid time (threshold), it is determined that there is a customer who uses the mobile phone 3 at a position not far from the longitude and latitude indicated by the GPS positioning information, and at the same time, the GPS positioning device has high position measurement accuracy (for example, accuracy) 100m) identifies the customer's location. That is, if the positioning information (latitude and longitude) is valid, it is possible to search a detailed map of the position where the customer is located. It should be noted that the effective elapsed time can be conveniently adjusted by the dispatch base station 40 (data in the database 16 is rewritten using the operation unit 13 or 21). It is also possible to calculate the rank of accuracy from the effective elapsed time and the elapsed time of positioning, and use this rank to perform control for switching the scale of the display map (detailed map to wide area map) described later. In step a15, the cell number acquisition process of the relay station 4 is performed, and the process proceeds to step a16. The process of acquiring the cell number of the relay station 4 is a process of transmitting a signal for requesting acquisition of the cell number from the transmission / reception unit 11 side to the telephone station side and obtaining information on the cell number of the relay station 4 of the outgoing telephone from the telephone station side. This is done in accordance with “Now Where Service” provided by the telephone office. In step a16, a process of searching and displaying a relay station map in the cell area of the relay station 4 indicated by the cell number is performed, and the process proceeds to step a17. In the relay station map display processing, first, the longitude and latitude range of the cell area of the relay station 4 indicated by the cell number is obtained by searching the positional information (stored in the database 16) of the relay station 4. Next, the relay station map is retrieved from the map information (stored in the database 16) using the longitude and latitude range, and is displayed. In step a17, a process for selecting a position (longitude and latitude) for selecting a detailed map is performed, and the process proceeds to step a6. The location selection process is based on a large scale map (relay station map, telephone station map, wide area map, etc.) that is displayed. This is a process of inputting the longitude and latitude of the location (for example, xx station, xx post office) as a detailed map search key. For selection of position coordinates by the operator, input from the operation unit 13 such as movement / click of the cursor on the display unit 14 is used. In step a18, a process for obtaining the management number of the public telephone 2 is performed, and the process proceeds to step a19. The processing for acquiring the management number of the public telephone 2 is performed by transmitting a signal for requesting acquisition of the management number from the transmission / reception unit 11 side to the telephone station side, and obtaining notification of the management number from the telephone station side. The receiving operator listens to the management number (for example, the name of the telephone office and a 5-digit numerical value) written on the public telephone 2 through a call with the customer, and processes the numerical value input from the operation unit 13 as the management number. You may make it do. In step a19, it is determined whether or not the management number of the public telephone 2 has been acquired. If the management number has been acquired, the process proceeds to step a20, and if not, the ordinary telephone 1 whose telephone number is not notified. Then, the process proceeds to step a21. In step a20, the management number position information (stored in the database 16) is searched using the management number of the public telephone 2 as a key, and the process proceeds to step a6. Based on the position (longitude / latitude) of the retrieved management number, a detailed map of the position where the customer is located can be retrieved. In step a21, processing for obtaining the telephone office number of the telephone used by the customer is performed, and the process proceeds to step a22. Since the telephone number is designated as non-notification, the receiving operator listens only to the telephone station number from the customer, and inputs the telephone station number from the operation unit 13. And the process which acquires the numerical value input from the operation part 13 as a telephone station number is performed. In step a22, it is determined whether the telephone station number has been acquired. If it has been acquired, the process proceeds to step a24, and if it has not been acquired, the process proceeds to step a23. In step a23, a process of displaying a wide area map (a map with a large scale) relating to the dispatch area is performed, and the process proceeds to step a17. The display of the wide area map is performed by searching for map information (stored in the database 16) based on the longitude and latitude range of the dispatch area. In step a24, processing for displaying a telephone station map indicating the service area of the telephone station indicated by the telephone station number is performed, and the process proceeds to step a17. In the telephone station map display process, first, the longitude and latitude range of the telephone station service area indicated by the telephone station number is obtained by searching the positional information (stored in the database 16) of the telephone station number. Next, the telephone office map is retrieved from the map information (stored in the database 16) using the longitude and latitude range and displayed.
