Abstract

PURPOSE:To attain the talking by receiving and identifying charging object permission information so as to use a called telephone number as a charging object thereby applying charging to the called party number by one magnetic card from an optional card type telephone set. CONSTITUTION:A caller checks whether or not charging object permissible information is stored on a magnetic card of a card unit 10 depending on the reception of a specific dial signal. When it is deceded that the information is stored, the signal is sent to a PB signal sending circuit 8 and sent to an exchange side EX via a talking circuit 9 as a PB signal. Further, a control circuit 7 prepares for the next dialing. The sent charging object permission information is received/analyzed by a central controller 4 via a channel controller 3, the charging object change call is identified and stored in a storage device 5. Then a called party telephone number is connected as the charging object and the charging object change is prepared. When the controller 4 receives the called party telephone number, the analysis is started, the digit number is checked and when normal, the talking connection is applied. The number is handled as the charging object number at the same time, stored in the device 5 to apply charging at the reply of the called party.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a magnetic card type public telephone system.

[Conventional technology]

Traditionally, people used public telephones to make calls to cities, offices, homes, etc. to call Pocketpel, but for example, with magnetic card telephones, when the magnetic card runs out of usage,
You have to prepare the next new magnetic card or prepare coins.

[Problems to be Solved by the Invention] In the above-described conventional magnetic card type telephone, by using a magnetic card, it is necessary to straddle a plurality of magnetic guards that are always available and carry a plurality of coins when making a call. For this reason, users find it extremely troublesome, and there is a problem in that those who use magnetic cards more than 17 times must always be aware of coins.

Furthermore, there was a problem in that the ``compound'' could not be used when the number of points used was exhausted or when new magnetic cards, coins, etc. were not available.

[Means for Solving the Problems] The magnetic card type public telephone system of the present invention has a magnetic card type telephone set housed in a switchboard. The information is read out and sent to the exchange, and the exchange receives and stores the billing target permission information from the magnetic card type V1 handset, and connects the called party's telephone number dialed by the caller as a billing target. This is what I did.

[For production]

In the present invention, the dial circuit sends out dial operation contents as a dial signal to the control circuit, and the FB signal sending circuit sends a PB defect signal to the exchange via the communication circuit in accordance with the PB sending signal from the control circuit. The exchange receives and identifies the billing target permission information sent by the PB defect signal, and makes the called party number the billing target.

〔Example〕

Embodiments of the present invention will be described in detail below based on the drawings.

The figure is a block diagram showing one embodiment of the present invention, and only the parts necessary for explanation are shown.

In the figure, EX indicates the exchange side, and TL
2 shows the side of the magnetic card 2'Wi phone.

On the exchange side EX, 1 is a call switch, 2 is a calling register trunk, 3 is a call path control device, 4 is a central control device, 5
is a storage device, and these communication path control device 3, central control device 4, and storage device 5 constitute a means for receiving and identifying billing target permission information in a converter and making the called party's telephone number a billing target. .

On the other hand, 6 of the magnetic card type telephone pick-up jTL is a dialing circuit that sends outgoing dialing operation contents as a dialing signal to the control circuit 7, 8 is a dividing line; -11EX via exchange
The dial circuit 6, one-way control circuit 7, and PB signal sending circuit 8 are the PB signal sending circuits that send out PB signals to the It constitutes the means for sending to the machine. This card unit 10 is a 10 card unit, and this card unit 10 is connected to the control circuit I.
With a magnetic card? It constitutes a means for reading out the note change information written in the note ζ1. Here, the control circuit γ reads out the contents of the permission information for all objects already registered in the magnetic card V of the card unit 10 according to the dial signal from the dial circuit 6, and sends out the PB signal as a PB sending signal. The signal is configured to be sent to the circuit 8.

Note that the other functions of the control circuit 7 and the functions of the telephone call circuit 9 and the card unit 10 are well known, so their explanation will be omitted here.

Then, in the magnetic card telephone vi side TL, the caller's specific dial is written on the magnetic card of the card unit 10. Read out the billing target permission information τ that has been set up and transfer it to IJEX. In this ZEX collecting machine, the magnetic card type is used. Receive all the above billing target permission 1 # information from M'M T L. The system is configured to store the called party's telephone number dialed by the caller and to connect the telephone number as a subject of whistle billing.

Next, the uJ production of the embodiment shown in this figure will be explained.

First, when the caller receives a specific dial 1 When it is determined that the charging target permission information t-PB is sent to the signal transmission circuit 8, ρ is transmitted to the communication circuit 9.
A PB defect signal is sent to the exchange side EX via. -!
In addition, the control circuit 7 is ready to be dialed into the arrow.

Next, as is well known, the billing permission information sent by the gXKPB signal on the exchange side is received and analyzed by the central control unit y4 via the channel control device 3, and is identified as a billing permitted call. , are stored in the storage device 5. Then, the telephone number of the called party '4 that is called next is connected as a billing object, and preparations are made to change the billing object.

Here, when the central control device 4 receives the called party's telephone number, it starts analyzing it, checks the number of digits of the received called party's telephone number, and if it is normal, the call connection is confirmed.
Do c.

At the same time, the number is handled as a billing number, stored in the storage device 5, and billed when the called party responds. Since the card-type telephone used by the caller is not charged, no charging pulse is sent to the card-type telephone. Also, if the received phone number search result is abnormal (/f
, sends a busy tone to the card-type telephone and cancels the connection.

Here, if the caller does not make a specific dial but performs a normal dial operation, the control circuit 7 determines that it is a "1 normal call", and the caller sends the dialed number to the PB signal sending circuit 8, and A PB double signal is sent to the exchange 1411EX via the circuit 9.

Since the central control device 4 of this exchange side EX does not have billing target permission information, the billing target is the telephone that made the call.

Similarly, when the caller makes a specific dial when the magnetic card does not have billing permission information, the billing permission information is not sent to the exchange, so the caller's telephone becomes the billing target.

〔Effect of the invention〕

As explained above, according to the present invention, there is a means for sending billing permission information to the exchange using a specific dial of a caller, a means for reading billing change information stored in a magnetic card, and a billing target at the exchange. By providing means for identifying the reception of permission information and charging the called party's telephone number, it is possible to charge the called party's number from any card-type telephone with a single magnetic card and make a call. Therefore, the practical effect is extremely large.
