Next, the operation of the embodiment of the present invention shown in FIG. 1 will be described with reference to FIGS. FIG. 2 is a diagram illustrating an initial process at the start of operation. FIG. 3 is a diagram illustrating an addition process when the activation of the partner device is confirmed. FIG.

This is a calculation formula for calculating how many times the transmitted day of the week points are on average. FIG. 11 is a calculation formula for calculating the coefficient of the transmission interval using the values obtained by the calculation formulas of FIGS.

The activation monitoring request control means 14 is adapted to execute the operation when an event requiring confirmation of activation of the partner device 50 occurs (FIG. 1).
See arrow A in the middle. Hereinafter, the arrow in FIG. 1 is indicated only by alphabets), and a start monitoring request is transmitted to the partner device via the communication control device 10b (B).

The activation monitoring request control means 14 notifies the activation monitoring request transmission interval calculation means 12 that the request has been transmitted (C).

The activation monitoring request transmission interval calculating means 12 having received the notification acquires the activation result information of the partner apparatus from the activation result information storage means 11 (D).

The method of managing information in the boot result information storage means 11 is as follows. As a management unit, one day is divided into 10-minute units (hereinafter, this unit is referred to as a time zone), and information on the activation time of the partner apparatus 50 is managed by points.

When the own device 10 confirms the activation of the partner device 50, the points are added in the first activation of the partner device 50 and the first activation after the stop. Therefore, the points increase as the number of times of activation of the partner device increases. Also, the total value of the points is managed. The day of the week is also managed by points for each day of the week, similarly to the time zone. Immediately after the start of operation, if there is almost no information, the collected information greatly affects the transmission interval. Therefore, at the start of operation, that is, the points for each time zone and day of the week are all “0”.
In the case of (Table above FIG. 2), "0.1" points are given in advance as initial values in advance, and the ratio of the small amount of actual information is suppressed (Table below FIG. 2).

Start monitoring request transmission interval calculation means 12
Calculates the interval until the next request is transmitted according to the following procedure based on the start result information acquired from the activation result information storage unit 11, the time zone in which the request was transmitted, and the day of the week. In order to prevent the transmission interval from becoming an extreme value,
The upper limit is determined in advance as 25 minutes, and the lower limit as 1 minute. The transmission interval reference value also serving as the initial value of the transmission interval is set to 10 minutes. Startup result information storage means 11
The information acquired from is the transmitted time zone, the point of the day of the week, and the point of the total value of the time zone and the day of the week. According to the calculation formulas of FIGS. 9 and 10, the number of points in the time zone and the day of the week is calculated as a multiple of the average value. X1 and x2
And In the case of a time zone, the average value is about “0.694%” because a 10-minute division is made, that is, one day is divided into 144 divisions. One day is about "14.3"%.

Next, based on x1 and x2, calculation is performed by the calculation formula of FIG. Let the obtained value be x. This x becomes a smaller value as the degree of concentration of the activation results becomes larger. This x,
The product of the transmission interval reference value and 10 minutes is the transmission interval. However, if the value is equal to or larger than the upper limit, the upper limit is the transmission interval. If it is equal to or less than the lower limit, the lower limit is the transmission interval.

Start monitoring request transmission interval calculating means 12
Notifies the activation monitoring request control means 14 of the obtained value (E). The activation monitoring request control means 14 sets the timer 16 using this value as a timer value (F). After the timeout (G), if the activation notification of the partner device 50 has not yet been received from the partner device activation confirmation unit 15, a start monitoring request is transmitted to the partner device 50 again via the communication control device 10b (B) and transmitted. This is notified to the activation monitoring request transmission interval calculating means 12 (C).

Until the activation of the partner device 50 is confirmed, B to
Repeat G.

When receiving a start notification from the partner device 50 via the communication control device 10b (H), the partner device activation confirmation unit 15 notifies the start result information correction unit 13 and the start monitoring request control unit 14 of the notification. (I, J).

The start result information correcting means 13 is provided for the partner device 5.
When the notification of the start confirmation of “0” is received from the partner device start confirmation unit 15, the time period (7:10 to 20 minutes in FIG. 3), the day of the week, and the respective days of the reception that the start result information storage unit 11 has received "1" points are added to the total value (K, L). However, the addition process for the day of the week is collectively performed on a weekly basis. Also, in the time zones before and after the start-up time zone (7:00 to 7:10, 7:20 to 30 minutes in FIG. 3), the addition of “0.2” points indicates that the transmission interval changes rapidly. prevent. The added points are not added to the total value because the purpose of the added points is not to reduce the ratio of the points in the transmitted time zone to the whole, but to shorten the transmission interval between the preceding and following time zones. (FIG. 3).

When the activation of the partner device 50 is confirmed by the activation monitoring request transmitted at a certain time, it is considered that the partner device has been activated before the previous request transmission time.
When the two times are in different time zones, points are distributed in consideration of the ratios belonging to the respective time zones. For example, as shown in FIG. 4, if the activation cannot be confirmed by the activation monitoring request transmitted at 7:15 and the activation can be confirmed by the next transmission at 7:23, the transmission interval of 8 minutes is first set to 5 minutes. (“5/8 = 0.625” points) and 3 minutes (“3/8 = 0.375” points) are added (the processing of arrow A in FIG. 4). Further, the addition processing of the preceding and following time zones described with reference to FIG. 3 is performed. In the time zone around 7:10 to 7:20, “0.625” point “0.
"0.125" points of 2 "times, and" 0.075 "points of" 0.2 "times of" 0.325 "points around 7: 20-7: 30, respectively Addition (process of arrow B in FIG. 4).

If the start-up monitoring request transmitted by the own device 10 and the start-up request transmitted first confirms the start-up of the partner device 50, the start time of the partner device 50 cannot be specified. Startup result information correction means 1
Do not call 3. Therefore, the activation result information storage unit 11
Is not updated (see FIG. 5B).
When the activation of the partner device 50 is confirmed by the subsequent or subsequent activation monitoring requests, the activation result information correction unit 13 is called (FIG. 5A).

After the timer 16 times out, the activation monitoring request control means 14 does not perform any processing because the activation of the partner device 50 has already been confirmed (the processing ends here).

The start result information correcting means 13 is provided for the partner device 50.
In order to respond quickly to the change of the start time, the start result information storage means 11 is stored in the start result information storage means 11 every time the date is changed so that the points added by the old start results (the left table in FIG. 6) gradually decrease. The points of the total time zone, the day of the week, and the total value of each of the pieces of the activation result information are multiplied by “0.91” (the right table in FIG. 6). The same multiplication process is performed for the day of the week.

As a result, the total value of the time zone is calculated as shown in FIG.
"50"% of the convergence value of the total value calculated from the calculation formula
(In this case, if it is less than “11.11” points), it is determined that the validity of the information held in the boot record information storage unit 11 has become suspicious, and the initial values are set to the points of all time zones and all days of the week. "0.1" points are added (FIG. 8).

FIG. 1 is only an example of a communication system to which the present invention is applied. The present invention is widely applied when the own apparatus 10 and the partner apparatus 50 to be monitored for activation are not on the same local area network, that is, connected via a router, a wide area network, or the like.

Further, it is also possible to provide a start monitoring request transmission interval optimizing device 10a similar to that of the own device 10 in the partner device 50, and to monitor the own device 10 from another device 50.

As described above, when the present invention is used, the time at which the partner device starts up is predicted based on the start-up results, and intensive monitoring is performed before and after that time. By increasing the transmission interval, it is possible to effectively monitor the activation of the partner device with a smaller number of activation monitoring request transmissions.

[0035]

As described above, according to the present invention, it is possible to monitor the activation of the partner device effectively with a small number of transmissions of the activation monitoring request.

In the conventional method of repeating transmission at regular intervals, if the transmission interval is 10 minutes, 144 requests are transmitted within 24 hours if the partner device has not been activated for 24 hours.

On the other hand, in the embodiment, when three months or more have passed after the operation in which the influence of the initial value is almost zero, the number of transmissions can be suppressed to about 90 times. Further, on a day of the week when there is almost no start-up record, the number can be suppressed to 60 or less.

The difference between the start time of the partner apparatus and the time at which the own apparatus recognizes it is 5 minutes on average in the conventional method, but in the embodiment of the present invention, the time period during which the start results are concentrated is Will fit within one minute on average.

That is, compared to the conventional technique, the communication cost for transmitting the start monitoring request can be reduced, and the occupation time of the resource (for example, CPU) of the own apparatus can be shortened.
In addition, it is possible to effectively monitor the activation of the partner device.

Therefore, the disadvantage of the conventional "monitoring transmission device" can be eliminated.
