Further, the mobile terminal 100 follows the operator's D1 screen in order to search for a route from the boarding station to the arrival station (XXH station in this example) before boarding at the boarding station (XXA station in this example), for example. By inputting the key, information such as a boarding station (for example, XXA station) and an arrival station (for example, XXH station) is input. Furthermore, you may input boarding time or arrival time. In the present embodiment, the boarding station may be referred to as XXA station, and the arrival station may be referred to as a disembarking station or XXH station.

  After the input information is received by the key control unit 303, a signal S1 is generated. The inquiry code can be appropriate identification information such as a number, a character, or a symbol for identifying the signal. The flag F1 is a flag (for example, 2 or 3) corresponding to each when a boarding time or arrival time is input, and a flag (for example, “current time”) when no time is input. 1). The input information is used as the time S1, XXA, and XXH. In addition, the mobile terminal 100 outputs a route search request including the S1 signal from the communication control unit 300 to the route search server 203.

  After receiving the signal S1, the route search server 203 refers to the station database 430 by route based on the XXA station and XXH station included in S1, and stores each data corresponding to the XXA station and XXH station from the station database 430 by route. Each is extracted (F200, F201). For example, a route code, route name, station longitude, latitude, and the like are extracted.

  In F202, the route search server 203 compares whether the XXA station and the XXH station are the same route based on the route code (or route name) of the data of the acquired XXA station and XXH station (F202). When the route code is the same (F202), the route search server 203 moves to F203 processing as the same route. On the other hand, when the route code is not the same (F202), that is, when the XXA station and the XXH station are not the same route, the route search server 203 extracts the transfer station (F204) and obtains data between the XXA station and the XXH station. The process proceeds to F203 processing for extracting and creating the optimum route extraction table 480. For example, each station is extracted from a database storing route data (for example, the name of a route station) including a route including XXA station and route data including a route including XXH station, a duplicate station is found and a transfer station is determined. it can. In addition, the transfer station may be extracted by using an appropriate method such as a known technique / method.

  In F203, for example, the route search server 203 extracts the data between the XXA station and the XXH station, and creates the optimum route extraction table 480 (F203). For example, adjacent station, distance between stations, travel time, departure time, arrival time, TOTAL distance, etc. are stored in the optimum route extraction table 480. Note that these data can be extracted and stored using a known technique, and detailed description thereof will be omitted. Note that the route search server 203 has one route when there is no transfer station. However, when there is a transfer station, a plurality of routes are extracted. The last arrival time can be obtained at the same time. In addition, for example, the optimum route extraction table 480 in which normal (no delay) operation state data is described is completed by assigning an order as the optimum order result at the final arrival time.

  Further, as shown in FIG. 11B, the route search server 203 uses the time route that arrives first as a result, and the boarding station, boarding time, transit station, transit time, arrival station, arrival time, and one transit station. Data such as the arrival time at the previous station, the arrival time at the previous station, the previous arrival station, and the arrival time at the previous arrival station are compiled and stored (F205). For example, the station included in the signal S1 can be used as the boarding station and the arrival station. As the transfer station, the station extracted in the F204 process can be used. For example, the station immediately before the transfer station and the station before arrival can obtain the station immediately before the station for transfer and arrival by referring to the adjacent station in the optimum route extraction table 480, for example. Note that the F205 process may be executed after an optimum result to be described later is obtained.

  The route search server 203 creates a signal S2 for inquiring about the operation state in F206, and transmits the created S2 to the track operation information server 201 (F206). The route search server 203 can appropriately generate the signal S2 as shown in FIGS. 7A to 7D depending on whether there is no connection and when there is a connection. In addition, the route search server 203 is in a waiting state until it receives an S3 signal from the track operation information server 201.

  Moving to FIG. 15, in F300 processing, the track operation information server 201 receives the S2 signal and then changes the operation status corresponding to the route code (requested route) included in S2 to, for example, the East Japan Railway Company (JR ) To create an S3 signal, and transmit the created S3 signal to the route search server 203 (F300). The extracted operation state can be used for the flag F2 of the S3 signal. Moreover, the time (for example, 20 minutes, 60 minutes etc.) according to the extracted operation state may be used for the time of S3 signal, and the delay time of the applicable route from the appropriate database which manages delay time is used. The delay time may be extracted and used.

  Returning to FIG. 12, the route search server 203 receives the S3 signal, and stores the flag F2 of the S3 signal in the operation state of the optimum route extraction table 480. Further, the route search server 203 adds a delay time corresponding to the operation state or a time included in the S3 signal to the final arrival time. Based on the added final arrival time, the route search server 203 sets the route that arrives in the shortest time or the route that arrives at the earliest time as an optimum result, creates an S4 signal according to the optimum result, and sends S4 to the mobile terminal 100. Notification is made (F210). The S4 signal indicates the boarding station, boarding time, transit station one station in front, transit one station arrival time, transit station, transit time, arrival one station, arrival one station stored in F205 processing. Arrival time, arrival station, arrival time can be included in this order. In addition, you may include the station on the way of a route other than this, time, etc. Further, the route search server 203 refers to the station database 430 for each station to be notified, acquires the station longitude and latitude, the route name, etc. corresponding to the corresponding station name, and transmits them to the mobile terminal 100. Good.

  The mobile terminal 100 receives the S4 signal, and notifies the operator of the search result by, for example, displaying the D2 or D3 screen shown in FIG. The screen display is controlled by the screen control unit 301. On the D2 or D3 screen, the presence / absence of the station arrival notification service is confirmed, and a request (notification request) in the case of being present is input. When no service is required, a request for no service may be input, and when nothing is input, no service may be set. By inputting a request when there is a service, subsequent notification time confirmation, movement check, re-search, and the like are performed.

  In addition, the mobile terminal 100 sets the movement schedule table 400 or 410. For example, the mobile terminal 100 stores the station name and time included in the S4 signal in the station name, the scheduled arrival time, and / or the scheduled departure time in the movement schedule 400 or 410. In addition, the mobile terminal 100 subtracts a predetermined time (for example, 5 minutes) from the scheduled arrival time, and stores it at the operation check time of the movement schedule table 400 or 410. The portable terminal 100 stores the station longitude, latitude, and route name corresponding to the station name received from the route search server 203 in association with the station name in the longitude, latitude, and route name of the movement schedule table 400 or 410, respectively. In addition, the mobile terminal 100 stores a map call symbol. As the map calling symbol, for example, a symbol for reading map data including the corresponding station can be used according to longitude and latitude.

  When there is no transfer, the mobile terminal 100 can create a table for the boarding station, the station just before the arrival station, and the arrival station, for example, as shown in the movement schedule table 400 of FIG. In addition, when there is a transfer, the mobile terminal 100, for example, as shown in the movement schedule table 410 of FIG. 9, a boarding station, one or more transfer one station and a transfer station, an arrival station one station, an arrival station A table can be created for the station.

The portable terminal 100 initializes (for example, resets) an operation status table 420 for use when confirming movement, for example. In addition, when the notification request is input, the mobile terminal 100 sets the automatic search operation state in the operation status table 420 to a value indicating operation (for example, 1). The mobile terminal 100 resets the movement schedule table 400 or 410 and the operation status table 420 when there is no notification request or when it is input that notification is not required.
After completion of the search display, the user gets on the target train, but the subsequent movement is left to the movement of the train. In the processing of the mobile phone 100, for example, a movement check is periodically performed by a movement check period program. Hereinafter, the movement check will be described.

  Moving to FIG. 13, the mobile terminal 100 checks the automatic search operation state of the operation state table 420 when the power is turned on or every predetermined movement check cycle (F111). If the automatic search operation state is set to “1”, the portable terminal 100 proceeds to F120 processing. The automatic search operation state set to “1” indicates that provision of a station arrival notification service is set. On the other hand, if the automatic search operation state is set to “0”, the portable terminal 100 returns to F111 processing and repeats the processing after F111 in the next movement check cycle.

  In F120, the mobile terminal 100 (for example, the search update control unit 307) compares the current time with each operation check time of the movement schedule 400 or 410 (F120). If there is a matching operation check time, the portable terminal 100 proceeds to F121 processing. At this time, the mobile terminal 100 can temporarily store whether the station name corresponding to the operation check time is a transfer station, an arrival station, or other (halfway station). On the other hand, when there is no matching operation check time, the portable terminal 100 returns to the F111 process and repeats the processes after F111 in the next movement check cycle.

  In F121, the portable terminal 100 creates an S5 signal, and the position confirmation control unit 305 transmits the S5 signal to the slave unit position confirmation server 200 in order to confirm the position at the current time (F121). For example, the mobile terminal 100 transmits its own telephone number that is set in advance in the S5 signal. In addition to the telephone number, an identifier such as a character, a number, or a symbol for specifying the mobile terminal 100 may be used. The portable terminal 100 waits until receiving the S8 signal.

  Moving to FIG. 16, the slave unit location confirmation server 200 receives the S5 signal and determines the location of the mobile number designated in the network (F500). For example, with reference to the slave unit location confirmation table 440 to 460, the location is specified by selecting a plurality of mobile station 205 having the inquired mobile number and specifying the location of the mobile terminal 100 from the corresponding electric field strength and base unit location. It is possible to specify the longitude and latitude of the mobile terminal 100 (slave device) using a general method such as. In addition, as a method for specifying the position of the mobile terminal 100, other appropriate methods such as using GPS can be used. Moreover, the subunit | mobile_unit location confirmation server 200 produces S7 signal, and transmits S7 signal to the subunit | mobile_unit corresponding station mapping server 204. FIG. For example, the slave unit location confirmation server 200 can generate the S7 signal by adding the longitude and latitude of the mobile terminal 100 to the received S5 signal.

  The slave location corresponding station mapping server 204 receives the S7 signal, maps the station position on the route of the train moving from the position of the mobile terminal 100 and the position (latitude, route) of the mobile terminal 100, and The station position of the terminal 100 is determined (F400). For example, the slave unit location-corresponding station mapping server 204 communicates with the route search server 203 to refer to the longitude / latitude of the station in the station database 430 for each route, and the location of the mobile terminal 100 and the location of the station included in the S7 signal. Stations that match with each other, or stations that have distances calculated based on longitude and latitude, or stations that have the shortest distance are determined. Stations can be determined for stations on the route. In addition to referring to the station database 430 for each route, the slave location corresponding station mapping server 204 may have a table in which stations and their position information are associated with each other.

  The slave location corresponding station mapping server 204 determines the station position, creates an S8 signal, and transmits the S8 signal to the mobile terminal 100 corresponding to the telephone number included in the S8 signal. For example, the slave unit location-corresponding station mapping server 204 can generate the S8 signal by adding the flag F3 and the station name of the determined station (for example, XXX station) to the received S7 signal. The flag F3 is “1” when the mobile terminal 100 is at the station indicated by the station name included in the S8 signal, “2” when the mobile terminal 100 is in the vicinity of the station, etc. When the position of the mobile terminal 100 is unknown, it can be “3”, but is not limited thereto. The portable terminal 100 receives the S8 signal from the slave unit location corresponding station mapping server 204. Thereby, it is possible to know its own position.

  Returning to FIG. 13, the portable terminal 100 determines whether or not the S8 signal has been normally received (F150). For example, when the mobile terminal 100 cannot receive the S8 signal within a predetermined time after transmitting the S5 signal, or when there is a communication error, it can be determined that the mobile terminal 100 has not received the signal normally.

  If the mobile terminal 100 has not successfully received the S8 signal (F150), the mobile terminal 100 determines whether the current position check is a checkpoint at a station on the way or a checkpoint at a transfer / get-off station (F151). . For example, if the data temporarily stored in F120 processing is a transfer station or an arrival station, the mobile terminal 100 determines that it is a checkpoint for a transfer / get-off station, and if the data is other (halfway station), the mobile station 100 checks the way station It can be judged as a point.

  In the case of a checkpoint at a station on the way, the mobile terminal 100 displays a D9 screen (F152), and proceeds to F111 processing (A). On the other hand, the mobile terminal 100 displays the D10 screen in the case of a checkpoint at a transfer / get-off station (F153). Further, in the case of transfer or getting off, the mobile terminal 100 has the next determination (whether to continue or end the service). (F154). When the mobile terminal 100 inputs information (for example, 1) indicating the continuation of the service, the mobile terminal 100 proceeds to F111 processing (A). On the other hand, when the information (for example, 2) indicating the end of the service is input. , F131 processing (E).

  When it is determined that the S8 signal is normally received in F150, the portable terminal 100 determines whether the station where the terminal 100 is located is a planned station (F122). For example, the mobile terminal 100 refers to the station name of the travel schedule 400 or 410 based on the station name included in the S8 signal, and acquires the scheduled arrival time and the scheduled departure time corresponding to the corresponding station name. Further, the mobile terminal 100 can determine whether the mobile terminal 100 is at the planned station by comparing the current time with the acquired scheduled arrival time, planned departure time, and the like. In addition to acquiring the time corresponding to the station name included in the S8 signal from the movement schedule table 400 or 410, the mobile terminal 100 further acquires, for example, the scheduled arrival time and the scheduled departure time for the stations before and after that. Then, it may be determined whether the user is at a scheduled location on the route (for example, between the front and rear stations). For example, it can be determined whether the received current station identification information indicates one of both end stations between the scheduled stations.

  In addition, for example, the mobile terminal 100 refers to the scheduled arrival time and the scheduled departure time of the travel schedule 400 or 410 based on the current time, acquires the station name that the mobile terminal 100 should be at the current time, and is acquired. Whether or not the mobile terminal 100 is at the planned station can be determined based on whether or not the station name matches the station name included in the S8 signal. Note that if the current time is after the scheduled departure time of a certain station and before the scheduled arrival time of the next station, the portable terminal 100 should be between the stations. The station name of the next station is acquired, and whether or not the mobile terminal 100 is at the planned station can be determined based on whether or not any of the acquired station names matches the station name included in the S8 signal.

  If it is determined that the station is a planned station, the mobile terminal 100 determines whether the station is a disembarking station, a transfer station, or an intermediate station (F130). For example, the mobile terminal 100 can make a determination based on whether the data temporarily stored in F120 is a transfer station, an arrival station, or other (halfway station). Further, referring to the schedule table 400 or 410 based on the station name included in the S8 signal, it may be determined whether the corresponding station name is a transfer station, an arrival station, or other (halfway station).

  When it is determined that the station where the terminal 100 is located is a disembarking station (F130), the mobile terminal 100 displays the D7 screen or the D8 screen shown in FIG. 6 (F123). In addition, the mobile terminal 100 sets a service stop flag in F131 and stops the service (F131). Specifically, the automatic search operation state of the operation state table 420 is set to “0”, and the process ends.

  On the other hand, when it is determined that the station where the terminal 100 is located is a transfer station (F130), the portable terminal 100 displays the D6 screen shown in FIG. 6 (F124) and returns to the F111 process (A). If it is determined that the station where the terminal 100 is located is a midway station (F130), the mobile terminal 100 displays the D12 screen shown in FIG. 6 (F125), and returns to the F111 process (A).

  If the portable terminal 100 determines in F122 processing that the station where the terminal 100 is located is not the position of the planned station, the portable terminal 100 determines that some kind of operation trouble has occurred and moves to F126 processing. In F126 processing, the mobile terminal 100 (for example, the route search control unit 304) creates an S9 signal and transmits the created S9 signal to the route search server 203 in order to perform search update on the assumption that the mobile terminal 100 is not operating normally. (F126). The station name included in the received S8 signal can be used as the current check station name of the S9 signal. For the current route name and the arrival station route, the current check station name and the route name corresponding to the arrival station can be acquired from the movement schedule table 400 or 410, for example, and the acquired data can be used. In addition, the portable terminal 100 will be in a waiting state after transmitting S9 signal.

  Moving to FIG. 14, the route search server 203 receives the S9 signal and performs a route re-search (F215). The re-search process is the same as the above-described F200 process to F205 process, and a description thereof will be omitted. Further, the route search server 203 creates an S2 signal and sends the created S2 signal to the track operation information server 201 to inquire about the operation state (F220).

  The track operation information server 201 receives the S2 signal, executes the F300 process in the same manner as described above, and transmits the S3 signal to the route search server 203. When receiving the S3 signal, the track operation information server 201 stores the F2 flag of the S3 signal in the operation state of the optimum route extraction table 480, and arrives in the shortest time based on the result of adding the delay time to the final arrival time. The S4 signal is generated according to the optimum result, and the route re-searched is notified by sending the S4 signal to the portable terminal 100 (F230).

  When the mobile terminal 100 (for example, the route search control unit 304 and the search update control unit 307) receives the S4 signal, the movement schedule table according to the S4 signal in both cases of no transfer (case 1) and transfer (case 2). The information 400 or 410 is updated (F134). In addition, the mobile terminal 100 displays the changed part of the moving schedule 400 or 410 on the screen control unit 301 by performing bold action / blinking / neon advertisement image / ring melody, vibration operation, etc. and / or The sounding control unit 302 is operated. For example, the screen control unit 301 displays a D4 screen or a D5 screen. At this time, the changed portion can be a bold character or the like. The portable terminal 100 moves to F111 processing (A).

  Further, the processing shown in FIG. 17 may be executed at an appropriate timing such as before the processing after the F111 processing is performed at the time of power ON and every movement check cycle. In F160 of FIG. 17, the search update control unit 307 of the mobile terminal 100 determines whether the current time is the arrival time one station before the transfer station, the arrival time one station before the arrival station, or a constant before the set arrival time. It is determined whether the time corresponds to one of the times (F160). When the mobile terminal 100 does not correspond to any time (F160), the mobile terminal 100 proceeds to the above-described process F111 (A). On the other hand, if the mobile terminal 100 corresponds to any time (F160), the designated changed part or the station name / time of the corresponding station is displayed in bold / flashing / neon advertisement image display / incoming melody. Then, the screen control unit 301 and the ringing control unit 302 operate so as to perform the vibration operation (F161). Thereafter, the process proceeds to F111 processing (A).

  In addition, when the operation information indicates a delay or disconnection of the route, the track operation information servers 201 and 202 communicate with the slave location corresponding station mapping server 204 to acquire the station identification information of the station where the mobile terminal 100 is located, When the station identification information of the mobile terminal 100 indicates a station on a delayed or disconnected route, electronic operation delay certificate information stored in advance may be issued to the mobile terminal 100. Or, when the station identification information of the mobile terminal 100 indicates a station on a delayed or non-communication route, the track operation information servers 201 and 202 are event information around the station for encouraging stoppage and purchase promotion, You may notify a terminal of bargain sale information, store information, etc.

  By performing the above processing, the mobile terminal 100 itself confirms its own position, checks the difference from the scheduled action, and if it deviates from the scheduled action, the route is searched again to notify the user of the operation state. Can be notified of the optimal route. In addition to notifying the optimal route, notifying the location at the checkpoint makes it possible to ride safely even on routes that you do not know. In addition, by notifying at the previous station, it is possible to prepare for getting off by transfer or preparation for getting off in advance, so it is possible to check on the mobile screen without seeing where the station is stopped in a full state it can.

  In the system of the above embodiment, the server makes an inquiry from the mobile side, so that simultaneous notification from the server is unnecessary, and the load on the server is distributed. By using the present invention, when a train delay occurs, a bargain sale at the nearest station, a tavern, etc. are used to notify the means of using leisure time while waiting for delay, thereby making use of waiting time This also has the effect of enabling notifications used in local sales promotions. In addition, it is possible to avoid the impact on business negotiations due to traffic delays by notifying information on nearby taxi companies and taking action without delay. Alternatively, a taxi company can use this service to provide a service that allows customers to ride at the nearest station when an operation delay occurs.

  The present invention is applicable to industries that provide train route search services. The present invention can also be used to provide services using mobile terminals such as mobile phones.
