  FIG. 4 is a flowchart showing the operation of the call control system 10. The flowchart of FIG. 4 is started when the call control device 200 of the call control device 200 and the mobile station 100 are powered on. First, the call control device 200 calculates the moving speed of the mobile station 100 based on the position information transmitted by the mobile station 100 (S10). If there is no call request from the external calling telephone 40 to the mobile station 100 (S20: No), the process returns to step S10. When there is a call request from the external calling telephone 40 to the mobile station 100 (S20: Yes), the call control device 200 controls the call of the telephone to the mobile station 100 (S30). In the present embodiment, the flowchart of FIG. 4 is started when the mobile station 100 is powered on, but is not limited thereto. As another example, an auxiliary power source that maintains a standby state even when the main power source of the mobile station 100 is turned off is turned on, and the call control device 200 issues a command for requesting location information to the mobile station 100 every predetermined time. The mobile station 100 may be activated by transmitting and receiving a command using the auxiliary power source of the mobile station 100, and the flowchart of FIG. 4 may be started. In this case, even when the mobile station 100 is conserved and the user 20 forgets to turn on the main power to the mobile station 100, the flowchart of FIG. 4 can be started.

  FIG. 5 is a flowchart showing the operation of the step (S10) of calculating the moving speed in the flowchart of FIG. First, the mobile station 100 transmits the identification information and position information of the mobile station 100 to the call control device 200 every predetermined time (S100). In the example shown in FIG. 2, the mobile station 100 transmits a telephone number “090-5366-XXXX” as identification information of the mobile station 100 together with latitude and longitude as position information every 5 minutes.

  The location history storage unit 240 of the call control device 200 stores the identification information and location information received from the mobile station 100 in association with the time when these pieces of information are received (S100). In the example shown in FIG. 2, the location history storage unit 240 uses the latitude “35 ° 39: 31” N and longitude “139 ° 44: 43” longitude as the location information of the mobile station 100 at the time “9:40”. Corresponding to the latitude “35 degrees 39 minutes 02 seconds north latitude” and “139 degrees 44 minutes 49 seconds east longitude”, which is further transmitted from the mobile station 100 after 5 minutes, corresponds to the time “9:45 minutes”. Store with attachments. The mobile station 100 may transmit time information together with the position information, and the position history storage unit 240 may store the position information received from the mobile station 100 and the time information in association with each other.

  The moving speed acquisition unit 250 calculates the moving speed of the mobile station 100 based on the identification information and position information of the mobile station 100 stored in the position history storage unit 240 (S110). In the above-described example, when the latitude and longitude associated with the latest time “9:45” in the history are stored in the position history storage unit 240, the time, latitude and latitude of the position history storage unit 240, In addition, based on the latest time “9:40” in the history, the latitude and longitude, it is calculated that the mobile station 100 has moved about 5 km in 5 minutes. The movement at 60 km is calculated. The movement speed acquisition unit 250 stores the calculated movement speed in the position history storage unit 240.

  Next, the destination display unit 230 determines whether or not the mobile station 100 is moving (S120). In the present embodiment, the destination display unit 230 determines that the mobile station 100 is moving when the moving speed of the mobile station 100 is equal to or higher than the reference speed. When the mobile station 100 is moving in step S60 (S120: Yes), the destination display unit 230 displays that the mobile station 100 is moving (S130). In the present embodiment, the destination display unit 230 refers to the position history storage unit 240 to determine whether or not the moving speed of the mobile station 100 is equal to or higher than a reference speed. When the mobile station 100 determines that the mobile station 100 is moving, the destination display unit 230 refers to the planned destination storage unit 270 from the identification information of the mobile station 100 to specify the name of the user 20 and specifies the specified user 20 And the fact that the user 20 is moving is projected onto the screen 204 and displayed. In the example illustrated in FIG. 2, the destination display unit 230 refers to the planned destination storage unit 270 when the identification information of the mobile station 100 determined to be moving is “090-5366-XXXX”. The user 20 “Matsumoto Taro” carrying the mobile station 100 with the identification information “090-5366-XXXX” is specified, and the fact that the user 20 “Matsumoto Taro” is moving is projected on the screen 204 and displayed. To do. Thereby, the other employee can grasp that the user 20 is moving without requesting the input of the user 20 or the other employee.

  Following step S130, the moving speed acquisition unit 250 identifies the moving direction of the user 20 carrying the mobile station 100, and the destination display unit 230 stores the user whose moving direction is stored in the planned destination storage unit 270. It is determined whether or not it matches the 20 scheduled destinations (S140). In the above example, the moving speed acquisition unit 250 determines the difference between the latitude and longitude at time “9:45” and the latitude and longitude at time “9:40” in the mobile station 100 carried by the user 20. On the basis of this, the user 20 “Matsumoto Taro” has a latitude of “35 ° 39: 31” north latitude and a longitude of “139 ° 44: 43” east longitude, that is, in the direction of north and west from the vicinity of Tokyo Tower. The positions of 19 seconds and 6 seconds, that is, the movement to the vicinity of Roppongi Station are calculated, and the destination display unit 230 is notified. The destination display unit 230 identifies the latitude and longitude of the planned destination “Company A Shinjuku headquarters” of the user 20 “Matsumoto Taro” by referring to the planned destination storage unit 270, and the specified latitude and longitude, Based on the difference between the latitude and longitude of the latest time “9:40”, the direction that the user 20 should move is northwest, that is, the direction of Shinjuku is northwest as viewed from the vicinity of Tokyo Tower. calculate. Further, the destination display unit 230 determines whether or not the direction in which the user 20 should move matches the direction in which the user 20 has actually moved. For example, in the above example, when the direction in which the user 20 “Matsumoto Taro” should move is northwest and the direction in which the user 20 has moved by time “9:45” is northwest, the destination display The unit 230 determines that the direction in which the user 20 has moved matches the planned destination “Company A Shinjuku Headquarters”. The destination display unit 230 may determine that the destination has coincided with the planned destination when the direction in which the user 20 has actually moved enters a range of 45 degrees to the left and right around the direction in which the user 20 should move.

  When the moving direction of the mobile station 100 identified by the moving speed acquisition unit 250 in step S140 matches the planned destination stored in the planned destination storage unit 270 (S140: Yes), the destination display unit 230 displays the user The scheduled destination of the user 20 is displayed together with the fact that 20 is moving (S150). Thereby, it can be grasped that the user 20 is heading to the planned destination as scheduled. On the other hand, when the moving direction of the mobile station 100 specified by the moving speed acquisition unit 250 in step S140 does not match the planned destination stored in the planned destination storage unit 270 (S140: No), the destination display unit 230 A warning that the planned destination is different from the actual direction of travel is transmitted to the mobile station 100 (S90), and the mobile station 100 that has received the warning displays this warning. Thereby, it is possible to notify the user 20 that the direction actually moved is different from the direction of the planned destination. In this case, the destination display unit 230 may display the planned destination of the user 20 projected on the screen 204 as blank or “warning”. Thereby, employees other than the user 20 can know that the user 20 is moving differently from the schedule. When the mobile station 100 receives a warning, the warning may be transmitted to the user 20 by voice or vibration in addition to or instead of being displayed on the screen of the mobile station 100.

  When the mobile station 100 is not moving in step S120 (S120: No), or when step S150 or step S160 is executed, this flowchart is ended.

  FIG. 6 is a flowchart showing the operation of the step (S30) for controlling the telephone call in the flowchart of FIG. When there is a call request from the external calling telephone 40 to the mobile station 100, the call control unit 260 refers to the position history storage unit 240 to determine whether the moving speed of the mobile station 100 is equal to or higher than the reference speed. It is determined whether or not (S300).

  In step S300, when the moving speed of the mobile station 100 is equal to or higher than the reference speed (S300: Yes), the call control unit 260 does not call the mobile station 100 (S310). In the above-described example, when the moving speed of the mobile station 100 is 60 km / h and the reference speed is 20 km / h, the call control unit 260 determines that the moving speed of the mobile station 100 is equal to or higher than the reference speed. In spite of the request for 40 calls, the mobile station 100 is not called. As a result, it is possible to prevent the user 20 carrying the mobile station 100 from hindering the driving of the vehicle, and it is possible to prevent the user 20 from calling and disturbing the surroundings while traveling by train. Further, the call control unit 260 notifies the calling telephone 40 that the mobile station 100 is moving (S320). As a result, it is possible to notify the caller of the calling telephone 40 that a call cannot be made because the mobile station 100 is moving. Further, the call control unit 260 may transfer a call request from the calling telephone 40 to the mobile station 100 to another telephone 60 instead of or in addition to step S320. As a result, when a call is not made to the mobile station 100, a person other than the user 20 can answer the call from the calling telephone 40 by the other telephone 60. Furthermore, the call control unit 260 stores an incoming call history in the incoming call history storage unit 280 for a call request from the calling telephone 40 that has not made a call to the mobile station 100 in step S310 (S330).

  On the other hand, when the moving speed of the mobile station 100 is less than the reference speed in step S300 (S300: No), the call control unit 260 calls the mobile station 100 (S370), and the call with the calling telephone 40 is terminated. (S350: No). When the call with the calling telephone 40 is terminated (S350: Yes), the call control unit 260 refers to the incoming call history storage unit 280, and the call control unit 260 stops the call while the mobile station 100 is moving. A history of incoming calls to the station 100 is notified (S360). In the present embodiment, the call control unit 260 notifies the mobile station 100 of the telephone number of the calling telephone 40 that requested the call as a history of incoming calls. As a result, the user 20 can be notified of a call that has been addressed to the user 20 during movement, and the user 20 can take measures such as making a call again from the mobile station 100 after the movement is completed. . Note that the call control unit 260 may notify all of the incoming call history stored in the incoming call history storage unit 280, a specific incoming call, for example, an incoming call from a caller registered in advance, or a predetermined call history. You may be notified of the latest number of incoming calls.

  After step S360 is executed, the call control unit 260 refers to the incoming call history storage unit 280 and notifies the calling telephone 40 stored in the incoming call history storage unit 280 that the mobile station 100 is able to talk. (S370). As a result, it is possible to notify the caller of the calling telephone 40 that was unable to make a call because it is moving, that the call with the mobile station 100 is possible, and the caller side again It is possible to take measures such as requesting a call. Thus, the operation of this flowchart ends.

  FIG. 7 shows an example of a display screen 300 that the destination display unit 230 of the call control device 200 in the call control system 10 projects on the screen 204. In the display screen 300, the user 20 and a call indicating that “currently moving” or “arrived” is transferred as the current destination of the planned destination and the planned destination in association with the user 20. Whether or not it can be performed and the movement start time are displayed. As a result, a person other than the user 20 can grasp the current destination of the target person and the movement to the planned destination. Further, since the destination display unit 230 displays the movement start time stored in the position history storage unit 240, a person other than the user 20 can predict the time until the user 20 arrives at the planned destination. .

  As described above, according to the present embodiment, it is possible for a person other than the user 20 to grasp that the user 20 is moving without requesting the user's 20 own input.

  In the above-described embodiment, the telephone number of the mobile station 100 is used as the identification information. However, instead of this, an employee ID uniquely assigned to the user 20 may be used as the identification information. In the above embodiment, the mobile station 100 transmits latitude and longitude as position information to the call control device 200. Instead, the mobile station 100 specifies a base station that communicates with the mobile station 100 as position information. Then, the base station information may be transmitted to the call control device 200. In this case, the call control device 200 includes a base station information storage unit that stores the position of the base station in association with base station information, for example, base station identification information for identifying the base station. Thereby, based on the base station identification information sequentially received from the mobile station 100 every predetermined time, by referring to the base station information storage unit and calculating the distance and direction between the base stations, the movement distance of the mobile station 100 And the moving direction can be calculated.

  In addition, the destination display unit 230 of the call control device 200 projects the display screen 300 onto the screen 204, but instead of or in addition to this, the call control device 200 includes a terminal of each user who uses the display screen 300. The display screen 300 may be displayed on these terminals.
