BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, the present invention will be described in detail with reference to the drawings.
FIG. 1 is a block diagram showing a network structure of an information distribution system including an access point telephone number automatic notification circuit according to the present invention.
In the figure, 1 is a database, 2 is an access point connected to the database 1 via a dedicated line, 3 is a public telephone line, and 4 is a terminal device connected to the public telephone line 3.
[0008]
Although only one access point 2 is shown in the figure, the same access point as the access point 2 is connected to the database 1 for each predetermined area.
Although only one terminal device 4 is shown in the figure, a large number of terminal devices installed in respective homes and the like are connected to the access point 2 respectively. It is provided with various devices necessary for request operation and use of request information, such as a controller, a display, and a speaker (not shown).
[0009]
The access point 2 has a large amount of data supplied from the database 1, and outputs predetermined information to the terminal device 4 in response to a request from the terminal device 4.
Thus, the access point 2 connects the central processing unit 20, the access point telephone number automatic notification circuit 21 and the data memory 22 connected to the central processing unit 20, and the central processing unit 20 and the public telephone line 3. And a modem 23.
[0010]
The data memory 22 stores a large amount of data supplied from the database 1. The access point telephone number automatic notification circuit 21 includes a telephone number identification circuit 210 is connected to the central processing unit 20, a number recording rewriting apparatus 211 connected to the telephone number identification circuit 210, rewriting number recording document 211 Connected to the memory 212.
[0011]
The telephone number identification circuit 210 analyzes the telephone number of the terminal device 4 that has received the request, determines whether or not the station number is in a range under the control of the access point 2. The CPU 20 transmits a download start signal to the processing device 20, and upon receiving the signal, the central processing device 20 calls information corresponding to the request information from the data memory 22, and transmits the information via the modem 23 and the public telephone line 3. This is output to the terminal device 4.
[0012]
On the other hand, when the terminal device 4 is out of the jurisdiction, the data of the telephone number of the terminal device 4 is transmitted to the number record rewriting device 211.
The memory 212 stores a telephone number of each access point and a list of telephone numbers managed by each access point. The number record rewriting device 211 receives the telephone number data from the telephone number identification circuit 210. An access point that controls the telephone number of the terminal device is sometimes selected from the record in the memory 212, and the telephone number of the access point is transmitted to the terminal device 4 via the central processing unit 20, the modem 23, and the public telephone line 3. Things.
[0013]
The terminal device 4 includes a central processing unit 40, a telephone number storage circuit 41 connected to the central processing unit 40, a dialing circuit 42, and a modem 43 for connecting the public telephone line 3 to the central processing unit 40. .
The telephone number storage circuit 41 stores the telephone number of the terminal device 4 and outputs the telephone number to the central processing unit 40 at the time of request.
[0014]
The dialing circuit 42 outputs a telephone number of the access point 2 recorded in advance to the central processing unit 40 in response to a command signal issued in response to the request operation, and automatically outputs the telephone number via the central processing unit 40. When the access point 2 is called by dialing, and the access point 2 transmits a new access point telephone number, the access point 2 telephone number recorded in the dialing circuit 42 is transmitted. Immediately replaced with a phone number.
[0015]
Therefore, in the information distribution system equipped with the access point telephone number automatic notification circuit, when an access point having jurisdiction over a specific telephone station is called from a terminal device having a telephone station number outside the jurisdiction, the information is recorded on the terminal device. The telephone number of the original access point is automatically rewritten to the optimal access point telephone number.
[0016]
When the telephone number of the access point is rewritten as described above, the information may be provided as it is, but when the rewriting is performed, the output of the request data from the terminal device is stopped and new access is performed. It is recommended that you call the points and receive the information again.
Further, the present invention is not limited to the above-described embodiments, but encompasses all modified embodiments that can be easily conceived by those skilled in the art from the above description.
