Description

[Detailed Description of the Invention] [Object of the Invention] (Industrial Application Field) The present invention is directed to a specific individual existing within a limited closed area, for example,
The present invention relates to a paging telephone system that makes it possible to call a specific person in a company or home without human intervention, and is compatible with ISDN.

(Prior art) Conventionally, in order to call a specific person to a telephone, within an extremely narrow range, the call must be made by local broadcasting, or through a so-called pager service [2. It is known for example when calling.

As is well known, in this pager service, a pager belonging to a specific person on the called side is called by radio, and the called person finds the nearest telephone and dials the calling party, and the specific person on the calling side is called over the phone. You will be called and have a conversation.

(Problems to be Solved by the Invention) However, in the above-mentioned conventional pager service, there is a problem that human intervention is always required between the specified person on the calling side and the specified person on the called side, and furthermore, it requires a large amount of waiting time. there were.

For this reason, there were problems in that confidentiality could not be ensured and that it took too much time in urgent cases.

In addition, pagers only have the function of receiving a call number, and the process of dialing the caller, calling a specific person on the caller, and talking to them is cumbersome.

The present invention has been made in view of the above conventional problems, and its purpose is to provide a paging telephone system that makes it possible to call a specific person in an extremely short time without any manual intervention. be.

[Structure of the Invention] (Means for Solving the Problems) In order to achieve the above object, the paging telephone system of the present invention is provided with a pager function, an authentication hood unique to the subscriber, and a plurality of parties to be called. a portable medium in which a side subscriber authentication code and a line address or an ISDN number part that is paired with the other side subscriber authentication code are registered; a telephone equipped with a function of wirelessly transmitting a subscriber authentication code; when the portable medium is attached to the telephone and a desired subscriber authentication code is specified, the specified subscriber The subscriber authentication code and the line address or ISDN number part corresponding to this authentication code are automatically sent to the line network, and the telephone set corresponding to the line address or ISDN number part on the receiving side wirelessly transmits the received subscriber authentication code. and calling the desired portable medium owner.

Furthermore, the subscriber-specific authentication code registered in the portable medium is an ID code that can be arbitrarily defined between the user and the parties with whom the user communicates, and can be stored at any time. It is characterized by

Furthermore, the telephone set is characterized in that it becomes possible to talk to the caller only when the called portable medium holder's portable medium is attached.

(Function) According to such a configuration, when a portable medium is loaded into a telephone and a desired subscriber authentication code of the other party is specified, the line address or ISDN number section corresponding to the specified subscriber authentication code of the other party is displayed. is automatically sent to the network. The telephone set corresponding to the transmitted line address or ISDN number part wirelessly transmits the subscriber authentication code of the other party. When the portable media of both the calling party and the receiving party are attached to their respective telephones, a telephone line is formed between the parties.

Therefore, it is possible to call a specific person who has a portable medium without human intervention and in an extremely short time.

Furthermore, since the system uses a "name" that is valid only between the parties involved, that is, a subscriber authentication code, as a key to identify a person, it is possible to eliminate call access from an unspecified number of people. As a result, it is possible to enjoy only the merits of the telephone, which are achieved while maintaining the confidentiality of a specific person's call number.

(Example) Hereinafter, a preferred example of the present invention will be described based on the drawings.

FIG. 1 is a block diagram showing the configuration of a paging telephone system according to the present invention, and this system is applied to ISDN.

As shown in the figure, telephones IA, IB and la.

1b is ISDN via the in-home data line termination device DSU.
It is connected to the public network 2. Telephone IA.

As will be described later, the IB, la, and lb are equipped with an IC card 3 as a portable medium, and a paging telephone system is achieved under the control of the IC card 3.

That is, these telephones IA, IB and 1a, 1b are the second
As shown in the figure, it has a numeric keypad 4 for entering numbers, function keys 5 to which various functions are assigned, and a liquid crystal (LCD) display 6 that can display the outgoing number, incoming number, time, etc. We are prepared. In particular, this embodiment is equipped with a card input device 7 that can input the data of the IC card 3, and when the IC card 3 is inserted from the insertion slot 8 opened on the front side of the phone, the data in the card is input. When the read or eject button 9 is pressed, the IC card 3 can be taken out.

Particularly, as shown in FIG. 3, the telephone of this embodiment is equipped with a one-way wireless paging section 300 in addition to the telephone output section 100 and the control section 200, and includes a line termination unit DSU and a control section selector 201. A subscriber authentication code is extracted from the group of numbers received via the interface 202 and transmitted from the antenna 400 as a weak radio wave.

The IC card 3 has a pager function and a function for inputting, processing, and outputting ISDN-compatible common line signals, and is also composed of a numeric keypad and function keys, as shown in FIG. 4. It includes a keyboard 10, an LCD display 11, and a contact 12 for connection to a card input device 7 of a telephone. moreover,
An antenna is embedded in this IC canid 3, and is configured to receive a wirelessly transmitted subscriber authentication code to achieve a pager function.

The electrical configuration of this IC card 3 is as shown in FIG.
An EPROM 14 in which programs for the PU 13 are stored, and a RAM 1 used as a work area for the CPU 13.
5.

The EFROM 14 stores a PIN code management program, a charge payment method control program, a call frequency control program, a shortened code management program, a display management program, a selection signal code management program, a number display program, and a charge display/remaining program. A frequency display program, an abnormality display program, etc. are written, and the CPU
In response to a read signal from 13, one of these programs is read and its processing is executed.

In particular, the IC card 3 of this embodiment includes a subscriber authentication (P, N) code storage section 16 configured with a ROM etc., a partner side P, N code storage section 17, a receiving section 18, and an antenna 19. and an alarm 20.

The P and N code storage section 16 can freely set an authentication code for identifying the user of the IC card 3, and stores the code. For example, enter the subscriber authentication code as “
TARO", this can be stored.

Note here that this subscriber authentication code is
It is not set in the interface section as a so-called "unique subaddress" defined below the SDN number section (line address, T point address). Nor is it identified within the telephone network as a code attached to a specific ISDN number section.

That is, this subscriber authentication code can be set as a component of the interface at any time by the telephone user, independently of the specific ISDN number part.

Therefore, when this subscriber authentication code travels within the telephone network as a signal, it only travels as a subaddress code of the appropriate ISDN address.

On the other hand, the other party's P and N code storage unit 17 stores the subscriber authentication code of the other party in the paging telephone system, and as shown in FIG. It is remembered as

In addition, in wireless paging to be described later, the receiving unit 18
A subscriber authentication code is received via antenna 19 and supplied to CP013. When this subscriber authentication code is received, the alarm 20 is designed to sound a dial tone.

Next, the operation of the system of this embodiment configured as described above will be explained with reference to FIG. 7.

Here, an IC card holder with subscriber authentication code "TARO" (hereinafter referred to as holder TARO) can also receive subscriber authentication code "JIR" through this paging telephone system.
A case will be explained using an example of paging the IC card holder of "O" (hereinafter referred to as holder JIRO).

First, the owner TARO inserts the IC card 3 in his possession into the nearest telephone IA (FIG. 7, process 1).

Next, the owner TARO inputs his personal identification code from the telephone IA. Then, in the IC card 3, according to the PIN code management program, it is determined whether the pre-stored code in the card matches the input code.

As a result of the determination, if the two hoods do not match, the IC1 card is not used by an authorized holder, and the subsequent paging function cannot be achieved. Here, if the two codes do not match, the IC inserted from phone A
The card 3 may be automatically ejected. Further, the password code may be input directly from the IC card 3. In this case, if the input code and the code inside the card do not match, the card will be automatically ejected even if it is inserted into the telephone IA.

Once the user's legitimacy is confirmed in this way, the ISD
A paging call is set up with N public network 2 (processing 2
).

Next, a paging request is sent (processing 3).

This paging request uses the subscriber authentication code “JIRO”
This is done by inputting the speed dial, for example, "*01" from the numeric keypad 4 of the telephone IA.

As a result, the subscriber authentication code "JIRO" of the holder JIRO is sent from the other party's P and N code storage section 17 of the IC card 3.
” and the IS corresponding to this subscriber authentication code “JIRO”
The DN address is called and these numbers are sent out in pairs. That is, in this paging request, the following data is sent.

“Receiver ISDN number/JIRO/TARO” Here, “Receiver ISDN number/JIRO” is the recipient ISD
N address. As an ISDN network function, an ISDN number is added to the telephone I of the owner TARO, which is the originator, on the public network side (process 4.5).

When the line terminating unit DSU on the called side is identified by the called party's ISDN number, multiple telephones under the jurisdiction of this line terminating unit DSU will simultaneously receive the subscriber authentication code "JI".
RO” as the calling code and the following data “J
The IRO/TARO/caller ISDN number is wirelessly transmitted into the air to execute radio paging (process 6). Here, "TARO/caller ISDN number" is the caller's l5
It is a UN address.

When the IC card 3 carried by the holder JIRO receives the wirelessly transmitted subscriber authentication code "JIRO" (process 7), the alarm 20 sounds and the subscriber authentication code "TA RO" of the sender is sounded. and its ISDN number are displayed on the liquid crystal display 11.

After the owner JIRO saw this display and confirmed the sender,
Insert the IC card into the nearest telephone (process 8).

Through this phone, “Caller 1sDN number/TARO/
1.:(7) The line termination unit DSU on the TARO side is specified by the IsDN number (processing 8.'9, 10.11).This line termination bag!fDsU
sends the received data to each phone under its jurisdiction, and sends the phone, Zunawa, and the owner TAR that has completed the match check.
The communication right is established with the telephone IA into which O's IC card 3 is inserted (Process PJ!11), and a request is made to the network to activate a calling signal (Process 12).

This call signal is sent to the phone IA into which the IC card 3 of the owner TARO is inserted and the IC card 3 of the owner JIRO.
When the two telephones are simultaneously sent to the inserted telephones, both telephones ring simultaneously (process 13). Then, when both parties take the receiver off-hook, the conversation begins (process 14).

After the call ends, when the user goes on-hook, a billing control signal is transmitted to the IC card 3 of the holder TARO, which is the originator.

Then, after predetermined processing such as billing processing is performed, telephone paging ends.

As shown in FIG. 8, in the above-mentioned "Processing 5", if there is a telephone in which the IC card of the holder JIRO is already installed, the line termination unit DSU sends the received data to each telephone, Along with this, each telephone transmits the subscriber authentication code "JIRO" WO wirelessly (Fig. 8, Process 6).
), but in the telephone set in which the card is installed, session processing is immediately started (processing 7 in FIG. 8). And “JI
Matching of the "Ro" card is confirmed (Process 8 in Figure 8)
Then, the same process as shown in FIG. 7 is executed.

In this way, according to the present embodiment, it is possible to automatically call a specific person by phone without any human intervention. Therefore, telephone paging can be accomplished in an extremely short time while maintaining confidentiality.

Furthermore, since the system uses a "name" that is valid only between the parties involved, that is, a subscriber authentication code, as a key to identify a person, it is possible to eliminate call access from an unspecified number of people. This makes it possible to enjoy only the advantage of the telephone, which is the ability to communicate with a specific person while maintaining confidentiality.

Furthermore, according to this system, communication carriers (C, C) are not forced to make unnecessary investments for paging.

This is because in order for a network to identify people at arbitrary locations, it is generally necessary to have a database in the network, but since this system uses wireless technology to identify people, it is possible to use the current pager network, for example. This is because paging can be performed without providing a database within the network if the following measures are taken. Local paging, such as in this example,
Furthermore, a method that utilizes a pager network is called global paging.

In addition, in the above embodiment, in process 13.14, the IC
When a ring signal is simultaneously sent to the phones in which Card 3 is inserted, both phones ring at the same time, and the call is started when both phones go off-hook, but the password is not entered. It may be configured such that a call can be started only when a match is confirmed with a password stored in advance on the telephone side, and if a match is not confirmed, a call cannot be made even if the handset is off-hook.

Furthermore, in this embodiment, the IC card 3 is used as a portable medium for telephone paging, but the shape is limited as long as it is a medium that can be attached to a telephone, such as a pencil-shaped IC pen. It is not something that will be done.

[Effects of the Invention] As explained above, according to the present invention, it is possible to automatically make a telephone call to a specific person without any human intervention. Therefore, telephone paging can be accomplished in an extremely short time while maintaining confidentiality.

Furthermore, since the system uses a "name" that is valid only between the parties involved, that is, a subscriber authentication code, as a key to identify a person, it is possible to eliminate call access from an unspecified number of people. This makes it possible to enjoy only the advantage of the telephone, which is the ability to communicate with a specific person while maintaining confidentiality.
