There is provided a reply means for distributing to either the providing server 400 or the route information providing server 500, obtaining route information according to the contents of the request, and returning the obtained route information to the portable terminal 100. Specifically, the route information is transferred to either the route information providing server 400 or the route information providing server 500 depending on the requester's transportation system, by moving by a private car, by using a public organization such as a train. Request a search for.

  In response to a request from the central server 300, the route information providing server 400 calculates the time required for the private vehicle from the current position of the mobile terminal 100 to the destination that is the planned destination, and notifies the central server 300 of it.

  In response to a request from the central server 300, the route information providing server 500 calculates a time required by a public institution such as a train from the current position of the mobile terminal 100 to a destination that is a planned destination, and notifies the central server 300 To do.

  Next, the mobile terminal 100 will be described. FIG. 2 is a block configuration diagram of the mobile terminal 100. The mobile terminal 100 includes a scheduler unit 10 (storage means), a time information providing unit 11, an input unit 12, a state management unit 13 (a monitoring mode instruction unit 101, a current location confirmation request unit 102, a change determination unit 103, and a required time request unit 104. (Required time acquisition means) and limit check unit 105 (alarm time information acquisition means), base station monitoring unit 13 (position change determination means), current location measurement unit 14 (position information acquisition means), alarm sounding unit 15 (alarm means). Hereinafter, each part will be described.

  The scheduler unit 10 is a part that stores a schedule of a user who holds the mobile terminal 100. Specifically, the scheduler unit 10 includes at least scheduled position information indicating a scheduled destination and a time at which the scheduled destination is reached (alarming an alarm). This is the part that stores the time to be associated). FIG. 3 is a conceptual diagram illustrating schedule information stored in the scheduler unit 10.

  As shown in FIG. 3, the schedule information stores alarm date / time, scheduled destination, alarm level, contents, transportation means, monitoring start date / time, margin time, and continuation flag in association with each other. The alarm date / time is the time at which the alarm is sounded based on the start time, arrival time, etc. of the event. This alarm date and time is rewritten as the user moves by a process described later. The planned destination is a target location, and is indicated by a name of a building or the like, an address, or a latitude and longitude. The alarm level indicates the pattern type of the ringing sound, and describes high, medium, and small. The higher the alarm level, the more the sound is set to sound a loud sound, a loud sound, etc. to indicate an emergency.

  The contents indicate specific contents of the user's schedule, and the user can grasp the schedule by looking at the sentences described in the contents. The transportation means indicates the transportation means to the planned destination, and specifically describes whether to move using a transportation means such as a train or to move using a private car.

  The monitoring start date and time indicates the timing when the state management unit starts monitoring the change of the existing area for the user, and describes the start date and time. In addition, “none” indicating that monitoring is not performed, “immediate activation” indicating immediate activation, “morning on the same day” activated on the morning of the day (for example, AM 6:00), and the like can also be described. The allowance time is a time for enabling the alarm to be sounded early and automatically so that the user can act with a margin. Here, it can be described in units of “minutes”. For example, if it is described as 10 minutes, the alarm will sound 10 minutes earlier depending on the date and time described as the alarm date and time.

  The continuation flag is a flag for causing the state management unit 13 to determine whether or not to continue the position interlock schedule function every time the user moves.

  Returning to FIG. 3, the input unit 12 is an operation panel capable of inputting alphanumeric characters and the like provided in the mobile terminal 100. The user can input a schedule to the scheduler unit 10 by operating the input unit 12. The example of a screen displayed on the display part (not shown) of the portable terminal 100 when inputting a schedule from the input part 12 is shown. FIG. 4 is an explanatory diagram illustrating an example of an input screen displayed on the mobile terminal 100.

  As shown in FIG. 4, the date and time that is the alarm date and time, the location indicating the planned destination, the alarm level, the contents, the transportation means, the monitoring start date and time, and the margin time are input. The information input here is stored in the scheduler unit 10 described above.

  Returning to FIG. 2, the state management unit 13 includes a monitoring mode instruction unit 101, a current location confirmation request unit 102, a change determination unit 103, a required time request unit 104, and a limit check unit 105, and mainly determines the current location of the mobile terminal 100. This is a part for measuring and acquiring the required time from the current location to the planned destination and rewriting the alarm time stored in the scheduler unit 10 based on the acquired required time. Hereinafter, each part will be described.

  The monitoring mode instruction unit 101 is a part that outputs to the base station monitoring unit 14 an instruction for starting a base station monitoring unit 14 to be described later based on schedule information stored in the scheduler unit 10.

  The current location confirmation request unit 102 receives the schedule information stored in the scheduler unit 10 and receives a monitoring start notification, or determines that a change has occurred in the location of the mobile terminal 100 by the base station monitoring unit 14 described later. When this is done, it is a part that outputs an instruction to measure the current location to the current location measuring unit 15 described later.

  The change determining unit 103 is a part that determines whether or not the current location requested by the current location confirmation requesting unit 102 has changed from the position at the previous request. When the change determination unit 103 determines that the change has occurred, the change determination unit 103 outputs an instruction to the required time request unit 104 described later to acquire the required time. If the change determination unit 103 determines that the change has not occurred, the change determination unit 103 again enters a standby state until an instruction is received from the current location confirmation request unit 102.

  When the required time request unit 104 receives a required time acquisition request instruction from the change determining unit 103, the required time required unit 104 needs to move from the current position to the planned destination for the central server 300 connected to the mobile phone network. Request time. An example of a request command when making a request is shown in the figure. FIG. 5 is a conceptual diagram showing a specific example of the search request command output to the central server 300 by the required time request unit 104 and the input search result. FIG. 5A is a conceptual diagram of the search request command. FIG. 5B is a conceptual diagram showing search results.

  As shown in FIG. 5A, the output search request command includes a search order ID, current location, current location abbreviation, destination, destination abbreviation, desired arrival date and time, and transportation. The search order ID is an ID for linking the search request and the search result, is an ID generated from the executed date and time, and is generated to be unique. The current location indicates the result of measuring the current location, and is described with latitude and longitude. The current location abbreviation is an abbreviation for the current location, and is obtained and described from map information that holds the building name, station name, etc. of the building in advance.

  The destination indicates a destination planned by the user shown with latitude and longitude. Latitude and longitude are calculated from map information stored in advance using a destination abbreviation described later.

  The destination abbreviation indicates a place input from the input unit 12 to the scheduler unit 10.

  The desired arrival date and time indicates an alarm time stored in the scheduler unit 10.

  The transportation means indicates the transportation means to be used, which is stored in the scheduler unit 10, and indicates whether to go to the planned destination using a private car or to go to the planned destination using a public institution.

  Next, search results will be described. As shown in FIG. 5B, the search result includes a search order ID and a required time (search result). As the search order ID, the search order ID extracted from the search request command is used so that it can be linked to the search request command. The required time indicates the required time required for movement from the current position of the mobile terminal 100 acquired by the central server 300 to the scheduled destination.

  By using the above commands, the required time request unit 104 can acquire the time required for the movement from the current position to the planned destination.

  Returning to FIG. 2, the limit check unit 105 is a part that registers an alarm level and a new alarm time corresponding to the degree of urgency in the scheduler unit 10 based on the acquired required time. More specifically, the limit check unit 105 determines the time required for the movement to the planned movement destination acquired by the required time request unit 104 and the alarm time stored in the scheduler unit 10 (if necessary, further margin Based on the time, a new alarm time is calculated. Then, the limit check unit 105 compares the calculated alarm time with the current time, and sets an alarm level and an alarm time according to the degree of urgency so that the user can arrive at the scheduled destination according to the schedule.

  The base station management unit 14 is a part that monitors a base station with which the mobile terminal 100 communicates wirelessly, and is a part that detects an area number included in a radio wave transmitted from the base station. The base station management unit 14 includes an area number storage unit that stores an area number of a base station that performs wireless communication. When the area number stored in the area number storage unit is changed, the mobile terminal 100 It is determined that the base station performing wireless communication has changed, and an instruction is output to the current location confirmation request unit 102 to confirm the current location.

  The current location measurement unit 15 is a part that measures a current location including latitude and longitude by GPS (Global Positioning System). In response to an instruction from the current location confirmation requesting unit 102, the current location measuring unit 15 can measure the current location by receiving radio waves from GPS satellites.

  Next, the operation of the mobile terminal 100 configured as described above will be described together with the operations of the central server 300 and the route information providing server 400. FIG. 6 is an operation flowchart showing a schematic operation of the mobile terminal 100.

  The scheduler unit 10 of the mobile terminal 100 sets the stored schedule information (S101), and then the base station monitoring unit 14 determines whether or not the base station that performs wireless communication in the mobile terminal 100 has changed. (S102). If the base station monitoring unit 14 determines that a change has occurred in the communicating base station, the current location confirmation requesting unit 102 acquires location information of the current location (S103).

  When the change determination unit 103 determines that the position information acquired now does not match the position information acquired last time, that is, when it is determined that a change has occurred in the existing position, the change determination unit 103 sets the required time request unit 104. Outputs instructions. The required time request unit 104 requests the central server 300 for the required time required to move to the planned destination (S104).

  When the central server 300 receives the search request command (see FIG. 5A) transmitted from the required time request unit 104 of the mobile terminal 100, the route information providing server 400 (in accordance with the transportation system designated by the search request command) ( Alternatively, the received search request command is transferred to the route information providing server 500) (S201).

  The route information providing server 400 calculates the time required to move to the planned destination based on the current position, the planned destination, and the desired arrival date and time (S301). In addition, since the calculation method here uses the well-known route search technique, detailed description is abbreviate | omitted. Then, the route information providing server 400 returns the calculated required time to the central server 300.

  In the central server 300, the received required time is further returned to the portable terminal 100. It is assumed that the central server 300 manages from which mobile terminal the required time is requested.

  The portable terminal 100 determines a time limit based on the received required time (S105). Specifically, the limit check unit 105 subtracts the required time (and spare time) from the alarm time stored in the scheduler unit 10 to obtain a new alarm time. Then, the limit check unit 105 registers a new alarm time in the scheduler unit 10.

  The scheduler unit 10 determines that the schedule information has been updated, compares the rewritten new alarm information with the current time, and determines how much time is available. The scheduler unit 10 outputs an instruction to the alarm sounding unit 16 to sound an alarm corresponding to the margin (or urgency).

  As described above, when the mobile terminal 100 detects the change of the base station, the mobile terminal 100 determines the actual change of the current location, acquires the time required to move to the planned destination described in the scheduler unit 10, and the scheduler unit 10 can be processed to update. This eliminates the need for unnecessary update processing of the scheduler unit 10.

  Hereinafter, detailed operations of the scheduler unit 10 and the state management unit 13 of the mobile terminal 100 will be described based on an operation flowchart. First, the operation of the scheduler unit 10 will be described. FIG. 7 is an operation flowchart showing an operation when a schedule is registered in the scheduler unit 10.

  The schedule information input by operating the operation unit 12 by the user of the mobile terminal 100 is received (S401), and the scheduler unit 10 stores the received schedule information (S402). The scheduler unit 10 receives an input from the user, checks the stored schedule information (S403), and determines whether it is a schedule for starting monitoring (S404).

  If the scheduler unit 10 determines that the schedule is not to start monitoring, the scheduler unit 10 checks the schedule that becomes the monitoring start time with a predetermined period, and enters a standby state (S405). When the scheduler unit 10 determines that the schedule is to start monitoring, the scheduler unit 10 sets the alarm time to be rewritten as the schedule to start monitoring, and outputs an instruction to enter the monitoring mode to the monitoring mode instruction unit 101 ( S406). Then, the scheduler unit 10 activates the state management unit 13 (S407).

  Next, the operation of the activated state management unit 13 will be described. FIG. 8 is an operation flowchart showing the operation of the state management unit 13.

  When the monitoring mode instruction unit 101 of the state management unit 13 receives a monitoring instruction based on the processing of S406 in FIG. 7 from the scheduler unit 10 (S501), the monitoring mode instruction unit 101 transmits a base to the base station monitoring unit 14. An instruction is output to detect the area number included in the radio wave from the station (S502). Receiving the instruction, the base station monitoring unit 14 shifts to the base station monitoring mode, operates to detect the area number transmitted from the base station, and store it in the area number storage unit.

  When the current location confirmation request unit 102 receives a notification signal indicating that the base station for wireless communication has changed from the base station monitoring unit 14 (S503), the current location confirmation request unit 102 sets a continuation flag in the scheduler unit 10. It is determined whether or not it is turned on (if there is a plurality of schedules, it is determined whether or not at least one continuation flag is turned on) (S504). When the current location confirmation request unit 102 determines that the continuation flag is on, the current location is confirmed by GPS (S506). If the current location confirmation requesting unit 102 determines that there is no continuation flag in the scheduler unit 10, the scheduler unit 10 instructs the monitoring mode instruction unit 101 to stop the monitoring mode so as to end the base station monitoring mode. Is output (S505). In order to allow the user to select whether or not to continue the monitoring mode, the fact may be displayed on a display unit (not shown) to enable selection by the user. Moreover, you may make it delete applicable schedule information from the scheduler part 10 at the time of the selection by a user.

  The change determination unit 103 determines whether or not the current position measured by the current position confirmation request unit 102 and the current position measurement position unit 15 is different from the previously measured position (S507). When the change determination unit 103 determines that the position is different, the required time request unit 104 requests the central server 200 for the required time required for moving from the current measured position to the planned destination (S508). ). Thereafter, the required time request unit 104 acquires the required time from the central server 200 (S509). When the change determination unit 103 determines that the positions are not different, the state management unit 13 waits until a change in the base station is detected again.

  Next, an operation when the alarm time described in the scheduler unit 10 is rewritten and reset based on the required time acquired by the state management unit 13 will be described. FIG. 9 is an operation flowchart showing an operation when the alarm time of the scheduler unit 10 is rewritten.

  The required time acquired by the required time request unit 104 is output to the limit check unit 105. The limit check unit 105 subtracts the alarm time set in the scheduler unit 10 from the value (time) obtained by adding the current time, the acquired required time, and the margin time set in the scheduler unit 10 (S601). . Then, the limit check unit 105 determines whether the remaining time obtained by subtraction is 0 or less, a predetermined value or more, or a predetermined value or less (S602).

  When the limit check unit 105 determines that the value calculated in S601 is 0 or less, the limit check unit 105 sets the alarm time to the current time and sets the alarm level to “high” (S603). In addition, “I can't make it in time” is added to the contents column, and “0” indicating the end is described in the continuation flag. If the limit check unit 105 determines that the value calculated in S601 is less than or equal to the predetermined value, the limit check unit 105 sets the alarm time to the current time and sets the alarm level to “medium” (S604). In addition, “Departure time is coming soon” is added to the content column. If the limit check unit 105 determines that the value calculated in S601 is equal to or greater than the predetermined value, the limit check unit 105 sets the alarm time to (alarm time−required time−allowance time) and sets the alarm level to “low”. Setting is made (S605). In addition, “Current location confirmed” is added to the content column.

  The limit check unit 105 registers the set alarm time and alarm level in the scheduler unit 10 (S606).

  Next, the operation of the scheduler unit 10 after the stored contents of the scheduler unit 10 are updated will be described. FIG. 10 is an operation flowchart showing an operation when the stored contents of the scheduler unit 10 are updated.

  When the scheduler unit 10 determines that the storage content of the scheduler unit 10 has been updated by the processing of S606 in FIG. 9 (S701), the scheduler unit 10 determines the alarm level of the updated schedule (S702). Then, the scheduler unit 10 outputs an instruction to the alarm sounding unit 16 to sound an alarm corresponding to the determined alarm level, and the alarm sounding unit 16 sounds a corresponding alarm (S703).

  Specifically, when the alarm level is set to “high”, the alarm sounding unit 16 sounds an alarm sound indicating that the user is in an emergency (for example, the sound is loud and the sound is unusual) To do). When the alarm level is set to “medium”, the alarm sounding unit 16 sounds an alarm indicating that it is time to take action. If the alarm level is set to “low”, the alarm sounding unit 16 sounds an alarm sound indicating that the schedule has been updated.

  After the alarm is sounded, the scheduler unit 10 displays the contents of the new schedule on the display unit (not shown) (S704). Thereafter, the processing returns to FIG.

  Next, normal operation of the scheduler unit 10 will be described. FIG. 11 is an operation flow diagram showing an operation when the scheduler unit 10 sounds an alarm at the registered alarm time.

  The scheduler unit 10 operates in parallel with the operation of the state management unit 13, and the scheduler unit 10 is registered at regular intervals while the state management unit 13 executes the processes shown in FIGS. The alarm time at which the alarm of the current schedule is sounded is checked (S801). When the scheduler unit 10 determines that the alarm time has been reached, the scheduler unit 10 outputs an instruction to the alarm ringing unit 16, and the alarm ringing unit 16 rings an alarm (S803). While sounding an alarm, the scheduler unit 10 displays the contents of the corresponding schedule (S804).

  Next, an operation sequence in the mobile terminal 100, the central server 300, and the route information providing server 400 will be described. FIG. 12 is an operation sequence diagram showing an operation after inputting a schedule.

  When receiving the schedule, the scheduler unit 10 sets the schedule (S406) and activates the state management unit 13 (S407). Further, the monitoring mode instruction unit 101 of the state management unit 13 outputs an instruction to the base station monitoring unit 14 to perform base station monitoring (S502). Then, the current confirmation requesting unit 102 outputs an instruction to confirm the current position to the current position measurement position unit 15, the current position measurement position unit 15 acquires the current position by GPS, and the current position confirmation request unit 102 determines the current position acquired by the current position determination request unit 102. The information shown is output (S506).

  Thereafter, the change determination unit 103 determines that the position has changed, and the required time request unit 104 requests the central server 200 for the required time required to move from the current location to the planned destination, which is the destination (S508). ). The central server 200 transfers a request for the time required for movement to either the route information providing server 400 or the route information providing server 500 based on the information indicating the transportation method that is the moving method received from the mobile terminal 100.

  Here, since it is registered in the portable terminal 100 that it moves with a private car and the information which shows the transportation is received, the central server 300 is the route information provision server 400 (server which searches the route for private vehicles). The request is transmitted to (S901). The central server 300 acquires the required time from the route information providing server 400, and transfers the acquired required time to the mobile terminal 100 (S509). Then, the state management unit 13 updates the scheduler unit 10 based on the required time (S510).

  Through the above operation, the user of the mobile terminal 100 acquires the time required for traveling from the current location corresponding to the transportation to the planned destination that is the destination, and updates the schedule of the scheduler unit 10 based on the acquired required time. It is possible to obtain a schedule that takes into account the time required for movement.

  Next, the operation when the base station is changed will be described. FIG. 13 is an operation sequence diagram showing the operation when the base station changes.

  When the base station monitoring unit 14 determines that a change has occurred in the area number of the base station with which it has communicated, the base station monitoring unit 14 notifies the state management unit 13 accordingly. The state management unit 13 outputs an instruction to acquire information indicating the current position to the current position measurement position unit 15, and the current position measurement position unit 15 acquires information indicating the current position. Then, the current position measurement position unit 15 outputs the acquired information indicating the current position to the state management unit 13 (S506).

  The state management unit 13 determines that the acquired current location is different from the previously acquired current location, and acquires the required time required for movement from the current location to the required destination of destination to the central server 300. A request is made (S508). Based on the information indicating the transportation facility received from the portable terminal 100, a request for the time required for movement is transferred to either the route information providing server 400 or the route information providing server 500.

  Here, since it is registered in the portable terminal 100 and traveling with a private car, and the information indicating the transportation is received, the central server 300 transmits the request to the route information providing server 400 (S901). The central server 300 acquires the required time from the route information providing server 400, and transfers the acquired required time to the mobile terminal 100 (S509). Then, the state management unit 13 updates the scheduler unit 10 based on the required time (S510).

  Through the above operation, the user of the mobile terminal 100 acquires the time required for traveling from the current location corresponding to the transportation to the planned destination that is the destination, and updates the schedule of the scheduler unit 10 based on the acquired required time. It is possible to obtain a schedule that takes into account the time required for movement. Furthermore, by performing these operations when there is a change in the base station, position information indicating the current location is not acquired until it is clear that there is no change in the current location.

  Next, the effect of the portable terminal 100 of this invention is demonstrated. The mobile terminal 100 of the present invention stores a schedule for storing the scheduled destination and the time to reach the scheduled destination in the scheduler unit 10 and changes the region where the user is located. The time required for the movement from the current position of the user to the planned destination is acquired from the central server 300, and the alarm is notified to the user in consideration of the required time, so that the area where the user is located is changed. Therefore, it is possible to acquire the required time required for movement, and to notify an alarm in consideration of the required time without performing useless acquisition processing.

  Further, the mobile terminal 100 can determine that the mobile terminal has moved with a simple configuration by determining that a change has occurred in the base station 200 that performs wireless communication.

  Further, the portable terminal 100 further subtracts the margin time from the alarm time indicated by the initially registered alarm time information in the limit check unit 105 to obtain new alarm time information, and uses the acquired alarm time information. By notifying the alarm when the indicated time is reached, it is possible to notify the alarm in consideration of the surplus time, and the user can reach the scheduled time without delaying the planned destination. Furthermore, it is possible to perform an action with a margin for the user.
