In the mobile communication terminal 2, the control unit 21 determines whether or not the current position of the predetermined user is set as the destination while the icon indicating the current position of the predetermined user is being displayed (A41). When the control unit 21 determines that the current position of the predetermined user is set as the destination by performing an operation of setting the current position of the predetermined user as the destination (A41: YES), the control unit 21 A route search from the position to the destination is performed (A42), and an estimated arrival time expected to arrive at the destination is calculated (A43). In this case, the control unit 21 performs a route search or calculates an estimated arrival time according to the moving means selected by the user. That is, if the user selects walking as the moving means, the control unit 21 performs route search on the assumption of movement by walking and calculates an estimated arrival time. In addition, if the user selects a vehicle as the moving means, the control unit 21 performs a route search on the assumption that the vehicle is moving and calculates an estimated arrival time. The control unit 21 calculates the time required to arrive at the destination from the current position by calculating the difference from the current time to the estimated arrival time (A44), and notifies the required time including the calculated required time. The signal is transmitted from the wide area communication unit 22 to the server 4. And the control part 31 performs route guidance using the result of a route search (A45). Thereafter, every time it is determined that the predetermined time has elapsed by the timer function (A46: YES), the control unit 21 returns to step A42 and repeats step A42 and subsequent steps.

  In the server 4, when the control unit 41 receives the required time notification signal transmitted from the mobile communication terminal 2 by the wide-area communication unit 42, the control unit 41 receives the received required time notification signal from the wide-area communication unit 22 by another user. It is transmitted to the mobile communication terminal 2. In another mobile communication terminal 2, when the control unit 21 receives the required time notification signal transmitted from the server 4 by the BT communication unit 23, the control unit 21 displays the required time included in the received required time notification signal on the display unit 26. (D1).

  In the mobile communication terminal 2, as shown in FIG. 21, the control unit 21 determines the movement of the current position of the predetermined user instead of determining that the predetermined time has elapsed by the timer function. Each time it is determined that the current position of the user has moved by a predetermined distance or more (A47: YES), the process may return to the above-described step A42 and repeat steps A42 and after.

  As a result of the series of processes described above, as shown in FIG. 23, the user A is mobile from the situation where the icons Ia and Ib indicating the current positions of the users A and B are superimposed on the map screen. When the current location of the user B is set as the destination in the communication terminal 2, the time required for the user A to move to the current location of the user B on the mobile communication terminal 2 possessed by the user B is displayed. In this case, the estimated arrival time may be displayed instead of the required time, or both the required time and the estimated arrival time may be displayed. In addition, information indicating that the required time is a calculation result in the mobile communication terminal 2 may be displayed, or information indicating whether the moving means is walking or a vehicle may be displayed. In this case, in the mobile communication terminal 2 possessed by the user A, the route R from the current position of the user A to the current position of the user B is displayed.

As described above, according to the present embodiment, the following effects can be obtained.
