Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a telephone exchange system using a portable storage device such as a magnetic card or the like, which allows an external call to be made by using the portable storage device.

[0002]

2. Description of the Related Art Taking a telephone as an example, although it is practiced to change services on a telephone-by-phone basis like a service class for a central line in a private telephone system, when an individual uses another person's telephone. Can only receive service of the class to which the phone belongs,
It was a service by terminal rather than by individual.

In order to solve this problem, as described in Japanese Patent Laid-Open No. 164363/1983, personal information stored in a portable storage device is read by a switching device via a telephone terminal. Some offer services according to personal information.

[0004]

In the former case of the above-mentioned prior art, there is a problem that the regulation of the call to the local line (the call to the outside line) is applicable to the telephone terminal and the regulation cannot be made by the user. On the other hand, in the latter, although it is possible for the user to regulate the call originating from the local line, the configuration requires that the portable storage device is always read when the telephone is used. In particular, there is a problem in operability because a portable storage device is required for a call without any restrictions. In particular, when installing a premises telephone system in a dormitory or the like, it is not necessary to put any restrictions on calls between the dormitory (extension line) and the dormitory room (extension line), and it is practical to regulate only local calls. desirable.

An object of the present invention is to allow an individual to own a portable storage device, to store personal information in the storage device, and to attach the portable storage device to the communication terminal, thereby making the communication terminal Read out the personal information,
Only when the personal information is received, the call from the office line is permitted, and an individual service is provided from an unspecified communication terminal.

[0006]

SUMMARY OF THE INVENTION The present invention accommodates a portable storage device for storing personal information, a plurality of communication terminal devices, a plurality of communication terminal devices and a public network line, and a call switching connection. In the telephone exchange system in which the exchange operation is performed in response to the personal information, one communication terminal device among the plurality of communication terminal devices stores the personal information from the portable storage device. When the personal information is read and is transferred to the exchange, the exchange determines whether the received personal information permits the call to the public network line. When the communication terminal device that has transferred the information is placed in a state in which it is possible to make a call to a public network line and the communication terminal device makes a call without transferring the personal information to the exchange device, the exchange device is Is above It does not allow a call to Shu network line, characterized by a call only the possible state to another of said communication terminal apparatus.

[0007]

According to the above-mentioned structure, a personal storage device such as a perforated card, a magnetic card, an electronic memory card, an optical memory card, and a handheld computer is owned by an individual.
Personal information such as the owner's identification number and outside line calling permission information is stored in the portable storage device, and the owner attaches the storage device to the communication terminal, whereby the communication terminal
The personal information stored in the storage device is read out if necessary, and further transferred to the control device of the communication network such as an exchange so that the storage device owner can make a local line call. Communication services can be provided.

Embodiments of the present invention will now be described in detail with reference to the drawings. An example of a service class for a central office line in a private branch exchange telephone will be described. Figure 1
FIG. 1 is an external view showing an example of a telephone used in this embodiment, which includes a handset 1-1, a push button dial 1-2, a magnetic card 1-
3, magnetic card reader 1-4, electronic key lamp board A1-5,
It is composed of an electric key lamp board B1-6, a display device 1-7 and the like. The magnetic card 1-3 stores the cardholder's identification number and the like. By inserting this into the magnetic card reader 1-4, the identification number and the like can be read by the telephone.

FIG. 2 is a block diagram showing the configuration of the telephone shown in FIG. 1, and FIG. 3 is a block diagram showing an example of a time division private branch exchange. In FIG. 3, each telephone 1 (1) to 1
The service class for the station line (n) allows incoming calls,
It is assumed that dialing is prohibited in the so-called "Kou". This is set as extension data on the storage device 9 of FIG. Each user of the telephone has a magnetic card, and the identification number (ID number) of the owner and the service class for the office line are magnetically stored in the magnetic card. It is assumed that the cardholder's identification number is "X" and the service class is "Tokukou" with no restrictions, and that the telephone line is now transmitted from the telephone 1 (1).

It is assumed that the calling party X uses the telephone 1 (1) and dials the station line, that is, dials "0" without inserting the magnetic card into the telephone. In this case, the connection proceeds in the same manner as a known private branch exchange, but since the service class is set to A'as described above, the connection cannot be established when it is identified by the "0" dial that it is a station line call. To notify the caller that the connection is not possible with an audible signal such as busy tone,
Connect to the talkie device and give voice guidance. In other words, if a magnetic card is not inserted, all station line dial transmissions are prohibited, so that unauthorized use of station line transmissions can be prevented.

Next, a case where the caller X makes a call from the telephone set 1 (1) using a magnetic card will be described. Insert your magnetic card 1-3 into the magnetic card reader 1-4 of FIG. 1 (401 in FIG. 4). Magnetic card reader 1-4 of FIG.
Reads the identification number "X" and service class "Tokuko" from the magnetic card, converts it into an electric signal, and sends it to the input / output interface 1-11. The control device 1-13 is controlled by a program, and when it receives the identification number "X" and the service class "special car" from the input / output interface, it stores this in the storage device 1-14 as the information of the user of the telephone. Remember. The magnetic card reader 1-4 has a function of identifying whether or not a magnetic card is inserted, and the stored information is held while the magnetic card is inserted (FIG. 4, 402). Next, when the caller X lifts the handset, the control device 1 shown in FIG.
-13 detects this and transfers the calling information to the exchange through the line interface 1-12 (403 in FIG. 4).
The telephone of FIG. 2 is assumed to be connected to the exchange through two pairs of cables, a telephone line and a data transmission line, and parts such as a power supply circuit not directly related to the present invention are omitted.

In FIG. 3, when the calling information is sent from the telephone 1 (1) through the data transmission line D, the central control unit 8 sends it through the signal receiving / distributing device 7 and the telephone interface 2 (1). Is received and controlled according to a program stored in the storage device 9, and a dial tone is sent to the telephone interface 2 (1) by a circuit (not shown). The dial tone is sent to the calling telephone set 1 (1) through the telephone line V to inform the calling party that the caller may dial (FIG. 4, 404). When the caller dials the first digit, the control circuit 1-13 shown in FIG.
This is received through -11 (405 in FIG. 4, 405), and it is determined whether the first digit is the office line transmission number "0" according to the program stored in the storage device 1-14 (406 in FIG. 4).
In the case of "0", the service class of the caller previously stored in the storage device 1-14 is read to determine whether or not the caller is permitted to connect to the central line (Fig. 4). , 40
7) As in this example, when the "special shell" is permitted, the information of the first digit "0", the identification number "X", and the service class "special shell" is set in the same route as the call information. Transfer to the exchange (408 in FIG. 5). When the central control unit 8 shown in FIG. 3 receives the information (409 in FIG. 5), the central controller 8 compares the information with the service class and determines whether or not the connection can be established (see FIG.
0) In this case, since there is no limitation on "special armor", the station is immediately connected to the central line (Fig. 5, 414). In this case, the service class "Kou '" when the magnetic card is not used is ignored. If the service class of the calling party X is not “Tokukou” but “Tokukou” permitted only in the city, or “Tokukou '” permitted in a specific suburban area, FIG. Therefore, it is not possible to make a determination, so it is next determined whether or not it is prohibited, that is, whether it is the above "Kou" or "special Kou '" (Fig. 5, 41).
1). If it is prohibited, the busy tone is sent to the caller (Figs. 5 and 412). If not, it is omitted in the figure, but the caller monitors the next dialed number. In addition, a process of artificially transmitting a dial tone from the office line to the calling party is performed. When the caller X dials the second digit, that is, the first digit to the office line and receives the dial digit (FIGS. 5 and 413), the pseudo dial tone is stopped (not shown) and the service class is resumed. Is checked (410 in FIG. 5). That is, if the second digit is other than "0" or "1", it is immediately connected to the central line (Fig. 5,
414), when the second number is "0" and the service class is "Kou", the processes of FIGS. 5, 411 and 412 are performed, and when the second number is "0" and "Koku", it is shown in FIG. , 411 cannot judge, so after receiving the next number, the service class is compared (see FIGS. 5, 413, 410, 41).
1), repeated until a decision is made.

After the connection is judged and the call is connected to the station line, the second and subsequent digits dialed by the caller are relayed to the station line (FIGS. 5 and 415) and the called party responds. When the response signal comes back from the central office line, the central control unit 8 receives it via the central office line interface 3 and the signal receiving / distributing device 7 (FIGS. 5 and 416), and the calling party and the called party are put into a talking state. (FIGS. 5 and 417).

As described above, conventionally, the service class that should be personal is fixed to the telephone, so even a person who is allowed to make a long-distance call can make a call from the telephone set to "A". There was an absurdity that people who were not allowed to call outside the city, and conversely even people who were not allowed to make out-of-city calls, could call anywhere from the telephone set to "special armor", This problem can be solved by giving an individual a card and changing the service class according to the information stored in the card.

In the present embodiment, the service class when the card is not used is set to "A '", but this may be set to anything and the service class is not limited to the local line. Absent. For example, it can be applied to a class that allows interruption during a call, which is called executive override.

Although a private branch exchange has been described as an example, it can be applied to the case of a public communication network. For example, if various services will increase in the future, such as whether to connect to an international line or whether to connect between a telephone network and a data network, and if the service contract determines whether or not the service will be available, install a card. , You can receive the service according to the contract no matter which phone or terminal you use.

In this embodiment, the case where the identification number and the service class are stored in the card has been described, but the identification number may be omitted if it is limited to the service class. For services in a small area such as a private branch exchange, the same service can be provided by storing only the identification number on the card and providing the exchange with a correspondence table of the identification number and service class. In the case of a nationwide scale, it is not realistic to make inquiries about the service class in the correspondence table of each affiliated station, so it may be effective to store even the service class in the card.

[0018]

As described above, according to the present invention, the personal information stored in the portable storage device is transferred to the exchange device only when a call is made to the office line (outside line), and normally, the exchange device is used. It is possible to improve the telephone exchange serviceability by restricting calls to the lines and allowing only calls between extensions.

In particular, if the present invention is applied to a premises telephone system installed in a dormitory, a company facility, etc., while improving the serviceability to users, it is possible to prevent outsiders from unintentionally calling the local line. This also makes it possible to optimize call charge management.
