Abstract

PURPOSE:To obtain the callee limiting card system of collect call by distributing a magnetic card recording a predetermined called party telephone number and providing a function reading the magnetic card and dialing a recorded incoming destination telephone number to a public telephone set. CONSTITUTION:A magnetic card 1 distributed to a caller user is used while being loaded to the card read section 3 of a public telephone set 2 and the card read section 3 reads a limit display as to the application of the card, a called telephone number and an effective call unit from the magnetic card 1. A dial signal generating section 4 receives incoming destination telephone number information generates a dial signal and sends it to a card type public telephone set circuit 5. When the card type public telephone set circuit 5 recognizes the limiting display as to the application of the card to be the call of the card system, the call is sent at first and a dial signal generated by the dial signal generating section 4 is sent to an exchange 6. Thus, the callee limiting card system is obtained, in which the user of collect call is limited.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a callee-limited card telephone system included in a call charging service.

[Conventional technology]

Conventional incoming call billing services do not have a callee-only card phone system as shown in the present invention, and services that are normally provided include, for example, collect call services, and recently, caller-free incoming call services are available. There is a service that uses a subscriber-paid incoming call line.

[Problem to be solved by the invention]

The above-mentioned conventional incoming call billing services are collect call services where you have to apply to the operator each time you make a call, and services that use an incoming call line where the caller pays free of charge. For example, it is first necessary to apply for membership as an incoming call billing service, and along with that, it is necessary to obtain a phone number for the new incoming call billing service and to advertise to the calling party's users.Furthermore, it is necessary to pay a separate amount in addition to the basic charge. The problem is that it is necessary. Furthermore, since telephone numbers are made public, it is difficult to limit the number of users as they are targeted at unspecified users, and in the current telephone network, it is only after a response from the switchboard that a public phone starts charging and is ready to make a call. Since it is based on reverse reception, there is also the problem that if the caller does not receive a response reversal and the call is toll-free to the called party, the call will be one-sided and the purpose of Zahis will not be achieved.

The purpose of the present invention is to distribute a magnetic card on which a predetermined destination telephone number is recorded to a calling user, and to read the magnetic card in a public telephone.
By providing the function to call a recorded destination phone number, the caller does not have to make a call themselves, and the caller receives a service that is equivalent to or better than that provided by setting up a free caller-paid incoming line. To provide a callee-limited card telephone system, which is a new service that does not require the callee to pay a basic charge, limits the number of users, and can be expected to be effective in advertising using the card itself.

[Means to solve the problem]

The callee-limited card telephone system of the present invention combines a magnetic card that records a predetermined call destination telephone number, an existing card-type public telephone circuit, and a function that reads the call destination telephone number recorded on the magnetic card. The public telephone includes a card reading section and a dial signal generating section that receives the output of the card reading section and generates a dial signal.

〔Example〕

Next, embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram of one embodiment of the present invention.

A magnetic card 1 distributed to a calling user is used by being inserted into a card reader 3 of a public telephone 2. The card reader 3 reads from the magnetic card 1 the limited display of the purpose of the card, the destination telephone number, and the number of valid calls. The dial signal generating section 4 receives the destination telephone number information read by the card reading section 3, generates a dial signal, and sends it to the card type public telephone circuit 5. The card-type public telephone circuit 5 includes all the functions of a public telephone that uses a known telephone card, and the limited display of the purpose of the card read by the card reading section 3 is used to make a call using a card telephone system for the called party only. When you know something is going on, the first thing you do is call.
Next, the dial signal generated by the dial signal generator 4 is sent to the exchange 6.

FIG. 2 is a configuration diagram showing the format of information stored in the magnetic card 1. As shown in FIG.

The stored contents include a limited display 7 regarding the use of the card, a called destination telephone number 8, and an effective number of calls 9.

Next, the operation will be explained.

A user of this service in possession of the magnetic card 1 inserts the magnetic card 1 into the card reading section 3 after going off-hook from the handset of the public telephone 2. As a result, the card reading section 3
reads the limited display 7 regarding the use of the card, the destination telephone number 8, and the number of valid calls 9 from the magnetic card 1, and sends the results to the card-type public telephone circuit 5. The destination telephone number 8 is sent to the dial signal generator 4 . When the power card type public telephone circuit 5 learns that the limited display 7 is a callee-only card telephone system service, it first makes a call, and then the dial signal generator 4 generates the dial signal of the called destination. It is sent to exchange 6.

When the called party answers and receives a response lever from exchange a6, the call begins. Thereafter, the operation is the same as that of a public telephone using a known telephone card, and the content of the effective call number 9 is rewritten according to the call number, so that it can be used as long as there is a remaining number of effective call numbers 9.

Also, if the effective call frequency 9 becomes 0 during a call,
The call can be continued by inserting a known telephone card or inserting coins. Since the above operation is no different from the conventional exchange connection operation, there is no need for any modifications or other changes to the exchange 6.

Since the magnetic card 1 can be freely printed on its surface, it can be expected to be very effective in advertising using this area.

〔Effect of the invention〕

As explained above, the present invention distributes a magnetic card on which a predetermined destination telephone number is recorded to a calling user, and then has the public telephone read and record the magnetic card. By providing the caller with the ability to make a call to a designated destination phone number, the caller does not have to dial the number themselves, and the caller receives a service that is equivalent to or better than that provided by setting up an incoming call line that is paid by the caller toll-free. The called party does not need to pay a basic fee, the number of users can be limited, and the effect is that a new service called a called party limited card telephone system can be obtained, which is expected to be effective in advertising using the card itself.
