Abstract

PURPOSE:To prevent artificial mistake and to save man-hour required for manual operation by providing a means calculating a distance between a service user and an access point and obtaining a nearby access point to a point to which the service user belongs and a means making automatic phone call to the obtained access point. CONSTITUTION:A general user (user's own station) utilizing a VAN service enters a toll station number of its own station telephone number to decide an access point to be utilized (step 6). Succeedingly, the entered toll station number is used as a key, management information of an accommodation station with respect to a central station is reference the toll station number of the central station to which user's own station belongs (step 7). The toll station number obtained in the step 7 is used as a key, nearby access point management information with respect to the central station is referenced to obtain a telephone number of the access point closest to user's own station (step 8) and the result is outputted onto a display device. Thus, the operation of an access point decision means 12 is made complete.

Description

[Detailed description of the invention] [Industrial application field] The present invention related to music.

[Traditional technique]

Traditionally, when a VAN service user decides which access point provided by a VAN provider to use, they have to make a decision based on a map or calculate the distance from a rectangular block number provided by NTT. He made decisions by means.

[Problem to be solved by the invention]

In the distance calculation using the rectangular block number provided by NTT in the conventional access point determination method described above, the rectangular block number is only displayed for each centralized station, and when the VAN service user calculates the distance, it is difficult to calculate the distance. In this case, the user had to find the upper centralized telephone office to which the user belongs, and then derive the rectangular block number, which was time-consuming. Also, select multiple access points and VANs that are considered to be nearby.
Since it is necessary to calculate the distance to the service user and find the closest access point, it is time-consuming and has the drawback of causing human error.

[Means to solve the problem]

The automatic access point selection system of the present invention calculates the distance between the service user and the access point based on the area code of the service user's telephone and the area code of the access point, and calculates the distance between the service user and the access point. The system includes means for determining the nearest access point, and means for automatically making a telephone call to the determined access point.

〔Example〕

Next, the present invention will be explained with reference to the drawings.

NTT's rectangular block number is used to find the distance between a general user (hereinafter referred to as "own station") using the VAN service and the location of the access point.

If you know the rectangular block number of your own station and the rectangular block number of the access point, use the formula for the distance between two points: Distance between two points = 2 ("1" t) + (yt 7*) (km). and the distance between the access points.

FIGS. 2(a) to 2(d) are conceptual diagrams of management information for access point determination in the present invention.

NTT's square block number is uniquely determined for the area code of the centralized station. Furthermore, area codes throughout the country include not only centralized stations, but also accommodating stations under centralized stations.

Since the area code of your own station may be the accommodating station, it is necessary to request the central station from the accommodating station. As management information for obtaining this information, as shown in FIG. 2(a) K, information on accommodating stations belonging to the centralized station is provided. Figure 2 (b) shows the NTT
This is the management information of the rectangular block number for the central station provided by the company.

From the rectangular block number information of the own station and the access point concentrated station obtained from Figures 2 (a) and (b), the above 2.
The distance management information between the access point and other centralized stations (FIG. 2C) is the result of distance calculation using the formula for the distance between points.

By looking at this, it is possible to know where the nearest centralized station is for each access point.

FIG. 2(d) is a different view of FIG. 2(c), and is for managing the closest access points to centralized stations throughout the country. By looking at this, the local station can know the access point closest to the central station to which it belongs.

Next, the operation of this embodiment will be explained.

First, the access point determining means 12 will be described.

As shown in Figure 1, a general user (his own office) using the VAN service enters the area code part of his own office's phone number in order to determine the access point to use (step 6). ).

Next, using the input area code as a key, the management information of the accommodating station for the central station is referred to, and the area code of the central station to which the local station belongs is determined (step 7).

Using the area code obtained in Step 7 as a key, refer to the access point management information of Moyoshi for the central station, find the telephone number of the access point closest to your own station (Step 8), and output the result on the display. do. This completes the operation of the access point determining means 12.

Next, the management information maintenance means 11 for access point determination will be described.

The access point determining means 12 ultimately refers to the nearest access point management information for the central station, but if the number of access point installation locations across the country increases, the access point determination means 12 may refer to the nearest access point management information for a certain central station. Access points may change.

In such a case, the access point determination management information maintenance means has a function of maintaining the access point management information closest to the central station.

First, the area code is extracted from the telephone number of the access point, and the area code of the central station to which the access point belongs is determined by referring to the management information of the accommodating station for the central station using this area code as a key.

(Step 1) Refer to the area code of the central station obtained in step 1 and the management information of the rectangular block number for the central station to obtain the square block number for the central station. (Step 2) Furthermore, obtain the rectangular block numbers for all centralized stations nationwide (Step 3).

The distance between the rectangular block number obtained in step 2 and the rectangular block number obtained in step 3 is calculated, and distance management information between the access point and other centralized stations is maintained. (Step 4) Based on the management information obtained in Step 4, the nearest access points to the central stations throughout the country are determined, and the nearest access point management information to the central stations is maintained. (Step 5) In this way,
Access point determination management information maintenance means 11
operation ends.

〔Effect of the invention〕

As explained above, by providing a function to automatically select an access point, the present invention can prevent human errors, reduce the number of manual steps required, and simplify operations. effective.
