Further, an interval suitable for the moving speed is selected by the notification cycle specifying means 122, and the interval of the notification of the position information is controlled.

Next, a description will be given of such a mobile station location registration method. FIG. 3 is a flowchart showing a processing procedure of the information processing means of the mobile communication device according to the embodiment of the present invention. When the mobile station starts up, the routine of the information notification means is executed. In the routine of the information notifying means, first, a routine of voice communication detection is called (S10).
0), it is checked whether or not the timer has been reset by voice communication detection (S200). If the timer has been reset, the following processing is interrupted. If it has not been reset, the routine of the notification cycle designation means is called (S300), and the timer is operated according to the speed. If the timer has timed out (S400), a position information notification is output to the wireless communication means, and a position information signal is transmitted (S500). Thereafter, the timer is set to 30 minutes (S600).

The voice communication detection routine (S100) will be described. In the voice communication detection routine (S100), it is checked whether or not the position information has been notified by voice communication (S101). If the position information has been notified by voice communication, the timer is set to 30 minutes (S10).
2). This prevents useless notification of position information after notification of position information by voice communication is performed.

Here, the operation at the time of initialization of the mobile station will be described. First, when the mobile station starts up, the routine of the information notification means is executed. In the routine of the information notifying means, first, a routine for detecting voice communication (S100) is called, and it is checked whether or not the position information is notified by voice communication. If the position information is notified by voice communication, the timer is set to 30 minutes. Set to. Here, it is assumed that the position information is not notified by voice communication, and the process returns to the routine of the information notification control unit. Next, the routine of the notification cycle specifying means is called. If the mobile station has not started moving, the notification cycle specifying means returns to the routine of the information notifying means without executing anything. Next, the state of the timer is checked. Here, the timer has not been set yet, and since it is in a time-out state, a position information signal is transmitted, and the timer is set to 30 minutes.

Next, the routine (S
300) will be described. FIG. 4 is a flowchart showing a processing procedure of the notification cycle designating means of the mobile communication device according to one embodiment of the present invention. Subsequently, assuming that the mobile station moves at an average speed of 50 km / h in the next two minutes, the process is led to the process (S320) by the determination (S310). In the process (S320), it is checked whether the remaining timer is less than 2 minutes, and if it is more than 2 minutes, the timer is set to 2 minutes and the routine returns to the information notifying means. Thereafter, the timer counts down sequentially and eventually times out. When the timer times out, a position information signal is sent out and the timer restarts.
Set to 0 minutes. In this operation, if the average moving speed of the mobile station does not change, the position information signal is transmitted at intervals of two minutes. Here, the mobile station enters the highway,
If the average speed increases to 90 km / h, the determination (S
310) and the process (S320), the timer is set to 1
The position information signal is transmitted every minute. When the average speed is 50 km / h, the movement for 2 minutes is about 1.67 km, and when the average speed is 90 km / h, the movement for 1 minute is 1.5 km, so that the position can be managed with an accuracy of 2 km or less. Further, if the average speed becomes 6 km / h or less due to traffic congestion or the like, nothing is performed in the routine of the notification cycle designating means, so that the position information signal is transmitted only once every 30 minutes. When the notification of the position information by the voice communication is detected in the above state, the re-timer is forcibly set to 30 minutes by the routine of the voice notification detecting means.

Next, a second embodiment of the present invention will be described. FIG. 5 is a block diagram of a mobile communication device according to a second embodiment of the present invention. The same components as those of the mobile station shown in FIG. 2 described above are denoted by the same reference numerals, and description thereof is omitted. The mobile station according to the second embodiment of the present invention has a clock 150 for detecting time. The clock 150 inputs the detected time to the notification cycle specifying means 122. The notification cycle designation unit 120 selects an optimal notification interval of the position information in consideration of the time factor in addition to the moving speed detected by the speed detection unit 130.

A method for registering the location of a mobile station having such a configuration will be described. FIG. 6 is a flowchart illustrating a processing procedure of a notification cycle specifying unit of the mobile communication device according to the second embodiment of the present invention. This corresponds to the routine (S300) of the notification cycle designation unit shown in FIG. The routine (S400) of the notification cycle specifying means determines a time element from the input time (S401). In this case, 8
The notification interval is selected in the judgment (S420) during the time periods when the traffic is large from 11:00 to 11:00 and from 15:00 to 17:00. In other time zones, the notification interval is selected in the normal time zone determination (S430). When a timer according to the moving speed is selected based on the determination in the time zone with heavy traffic (S420) or the determination in the normal time zone (S430), a timer process (S410) is performed. Details of each process are the same as those in FIG. As described above, in the determination in the time zone where the traffic is large (S420), the determination in the normal time zone (S430) is performed.
Accordingly, the notification interval of the position information is doubled, and the number of times of notification is halved.

The above processing functions can be realized by a computer. In this case, the processing contents of the functions that the mobile communication device should have are described in a program recorded on a computer-readable recording medium. Then, by executing this program on a computer, the above processing is realized on the computer. Examples of the computer-readable recording medium include a magnetic recording device and a semiconductor memory.

As described above, according to the present invention, it is not necessary to perform communication for notifying position information by notifying position information at the time of voice communication. In addition, when there is no voice communication, by performing at optimal intervals according to the moving speed, the position of the mobile station can be more accurately known, and
Unnecessary notification avoids pressure on traffic. Further, by changing the notification interval depending on the time zone, communication concentration can be avoided.
