Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement in a telephone system, and relates to a personal call communication system for calling an individual using a portable receiver such as a pager.

[Conventional technology]

In a conventional communication system, for example, a telephone system, a number is given to each telephone which is a terminal device, and when making a call, the other party dials the number of the telephone corresponding to the other party to be called, so that the other party can make the call. I was expecting to be near the phone. However, in offices, etc., it is not always possible to be at the seat and it is often impossible to achieve the purpose.Therefore, the portable receiver is called by electromagnetic waves, and the called person returns and calls the predetermined telephone. There is a so-called pager service for making a call.

[Problems to be solved by the invention]

However, the pager service generally takes a long time because it calls the telephone of the desired party once and then makes a pager call after it is found out.
Also, when the person who should carry the pager does not answer the call, or when the bearer of the pager is outside the pager service area, a return call is not made from the person who is paged, so there is no call at all. A problem arises in that contact by telephone cannot be made.

SUMMARY OF THE INVENTION It is an object of the present invention to perform a personal call by a portable receiver and, if there is no response, transfer the call to a predetermined telephone so as to contact the caller with a minimum telephone contact means. And to the caller,
To provide a personal call communication system in which the change of the destination and the form of the call (the change of the pager call to a general telephone call) is notified by voice information to improve the serviceability of the personal call. is there.

[Means for solving the problem]

An object of the present invention is to provide a portable receiver that responds to call information by a radio signal, a plurality of communication terminal devices, an exchange device that accommodates these communication terminal devices by wire, and performs exchange connection between the communication terminal devices, A personal call communication system comprising: a transmitter for transmitting the call information for calling the portable receiver based on information received from the switching device. When receiving the information for calling the receiver, transmitting the calling signal from the transmitter and calling the portable receiver, when receiving the response information corresponding to the portable receiver, transmitting the response information Connecting the second communication terminal device with the first communication terminal device, and receiving no response information corresponding to the portable receiver, a third communication terminal which is determined in advance. In which it is achieved by a control apparatus connected device and a said first communication terminal device.

[Action]

With the above-described configuration, when a portable receiver is called and there is no response from a called party having the portable receiver, an automatic call is made to a telephone such as an office to which the called party belongs. And a minimum number of telephone contacts (message messages, etc.) are possible.

〔Example〕

Hereinafter, an embodiment in which the present invention is applied to a private branch exchange will be described.

The telephone is, for example, a telephone with an ID card reader as shown in FIG. 1, and a new type of telephone capable of exchanging data with an exchange as shown in FIG.

Each person using the telephone has a call signal receiver 14 (FIG. 4) having the same function as the pager receiver, and an ID card 1-3 (FIG. 1). In this embodiment, it is assumed that a credit card size ID receiver shown in FIG. 2 in which a receiver and an ID card are integrated and a display device for displaying a caller number is incorporated.

The phone number is not given to the phone,
Given to individuals, ie receivers and ID cards.
The phone number can be the same as the ID number, but is generally already
For example, each employee is given an employee number,
It is desirable that the ID number matches this. On the other hand, since it is desirable that the telephone number has the minimum required number of digits, the telephone number is given independently of the ID number, and an exchange table is provided in the exchange to have a correspondence between the two. It is not necessary to assign a telephone number to the telephone, but if it is desired to make a person-to-station call in addition to a person-to-person call, the telephone can also be assigned a number.

In the telephone of FIG. 1, when the user is present, the ID card 1
-3 is inserted into the ID card reader 1-4. As the ID card 1-3, a card integrated with the personal call receiver shown in FIG. 2 is used.

The receiver shown in FIG. 2 is obtained by incorporating a pager receiver into a thin plastic-like card by making full use of membrane technology, and further includes a dot matrix display device 14-1. The card also has a built-in piezoelectric ceramic heating element, battery, and antenna.
3. An electronic key 14-4 for display erasure is incorporated using a capacitance detection type electronic key. 14-5 is the name entry space, 14-
Reference numeral 2 denotes a magnetic stripe for storing an ID code.

The telephone 1 is a telephone network 1 for telephone calls as shown in FIG.
-8, a transmitter 1-9, a receiver 1-10, a dial 1-2 controlled by a controller 1-13, an ID card reader 1-4, an electronic key board 1-5, 1-6. , Display device 1
-7, an input / output interface 1-11, a line interface 1-12, a storage device 1-14, and a character generator 1-15.

Calls can be made without inserting an ID card into the phone when calling, but in this case, caller notification cannot be made. Here, the operation when a card is inserted will be described.

The caller attaches the ID card to the nearest, generally his, telephone (FIG. 5-1, 501). Subsequently, when the handset is raised (FIG. 5-1, 502), the control device 1-1 of FIG.
3 detects this, drives the ID card reader 1-4 via the input / output interface 1-11, and reads the caller ID number stored in the magnetic stripe of FIG. 2 (5-1).
Figure, 503). The control device 1-13 transmits the calling information indicating that the handset has been picked up and the ID number of the caller to the line interface 1-12.
(FIG. 5-1, 504). In the exchange, the central control unit 8 is connected via the telephone interface 2.
Receives this and stores the ID number as caller information (FIG. 4). The central control unit 8 determines whether the calling ID number is in the calling management table in the storage device 9 which stores the called party ID number of the calling party in order to identify whether the call is a calling or answering. Verification (FIG. 5-1, 505). If there is no call, it is determined that the call is not being made, that is, it is not a response but a call, and a dial tone is transmitted from a circuit (not shown) through the switching network (FIG. 5-1, 506).

After listening to the transmission tone, the caller dials the telephone number of the called party. The dialing is performed by pressing the push button dial 1-2 of FIG. 3, which is read by the controller 1-13 via the input / output interface 1-11, and transferred to the exchange via the line interface 1-12. Is done. The dial transferred to the exchange is received by the central controller 8 through the telephone interface 2 of FIG. 4 (5-1).
(Fig. 507). The central control device 8 refers to the correspondence table between the telephone numbers and the ID numbers stored in the storage device 9,
Convert the called number to the called party's ID number (see FIG. 5-1, 50).
8). Further, the central control unit 8 converts the caller ID number into a caller name according to the ID number-name correspondence table stored in the storage device 9 (509 in FIG. 5-2). Central control unit 8
Indicates the above-mentioned called party ID number and calling party name
(510 in FIG. 5-2), and the caller information such as the called party ID number, the calling telephone, and the calling party ID number are registered in the calling management table in the storage device 9 (FIG. 5). -2, 51
3). At this time, the non-response monitoring timer also starts counting (FIG. 5-2, 514).

In FIG. 4, when the personal call control device 10 receives the called party ID number and the calling party name, it activates the modulator 11 to convert it into a radio signal and transfers the information (FIG. 5-2, 511). Here, the radio signal is not limited to an electromagnetic wave, but is a general signal for transmitting information using light waves, ultrasonic waves, and the like. A modulation method is a method of transmitting a digital code on a time axis, and a spectrum is spread on a frequency axis. Although various methods and the like can be considered, in general, modulation is directly performed on the time axis by frequency shift keying (FSK) using an electromagnetic wave. The modulated signal is amplified by the transmitter 12 and transmitted from the antenna 13 (FIG. 5-2, 51).
2).

The transmitted radio wave is received by all the receivers 14 in the radio wave arrival area shown in FIG. The receiver 14 is a card having the appearance as shown in FIG. 2, and has the same functions as the pager receiver, but also incorporates a caller name display device and a magnetic stripe as described above. is there.

Upon receiving the radio wave, the receiver 14 checks whether the called ID number is its own ID number, and ignores it if it does not match. If the names match, the caller's name sent subsequently is received, converted to a character pattern and displayed on the display device 14-1, and the piezoelectric element is driven to generate an audible signal (5-th). Figure 2,
515). The carrier of the receiver 14 knows the incoming call by the ringing of the receiver, but can know who the caller is by looking at the display device 14-1 on the receiver. The audible sound is stopped by pressing the tone stop key 14-3 on the receiver.
The name can be deleted by pressing the display deletion key 14-3.

To answer an incoming call, go to a nearby telephone and attach an ID card to the telephone (FIG. 5-1, 501).
This operation and the operation of the system are the same as those in the case of calling (FIG. 5-1, 501 to 504), and the ID number of the called party is transferred to the exchange.

Then, the central control device 8 in FIG.
When it is determined in step 5 that the call is originating, the responder's ID number is already registered as the calling ID number in the calling management table in the storage device 9 in FIG. 4 (according to FIGS. 5-2 and 513). Therefore, a match is obtained and the judgment is NO, and it is recognized that the call is originated as a response. That is, the central control unit 8 reads out the caller information corresponding to the called party, that is, the calling telephone set and the caller ID from the calling management table (5-1).
(Fig. 516), and the calling and called telephones are connected (5-1).
(Fig. 517), and put into a talking state (Fig. 5-1, 518). At this time, the name of the calling party can be displayed again on the called telephone.

In this way, the calling party can talk to the desired called party.

In addition, at the time of presence, if you attach an ID card, that is, a receiver to your phone, the receiver will ring on the phone,
You can respond with the same operation as a conventional telephone.

Next, a description will be given of measures to be taken when the called party is outside the callable area or when the called party does not respond by seeing the calling party name.

Even when a person-to-person call is dominant, an out-of-office message is still required. If the communication system has a mail service function, messages can be sent without human intervention, but this is not always common. Here, one embodiment of the processing at the time of non-response will be described below with reference to FIG.

As shown in FIG. 5-2, 514, the non-response monitoring timer starts counting at the same time as the start of the call. If the timer exceeds a preset time, for example, 30 seconds, a timeout occurs (601 in FIG. 6), and the central controller 8 is notified. The central control unit 8 reads out the caller information from the calling management table according to the called party ID which has timed out (FIG. 6, 60).
Along with 2), the information about the called party is deleted from the table.

On the other hand, the central controller 8 connects the announcement machine 7 shown in FIG. 4 to the calling telephone to connect the calling party with a message saying, for example, "There is no response, so contact the called party's telephone." (Fig. 6, 60
3). Here, the telephone of the called party means that each person registers in advance the telephone that he / she always uses, and, under the registered telephone, the secretary of the called party or a person who has a seat nearby. , And try to get a message and destination guidance. A telephone registration table indicating the correspondence between the ID number and the registered telephone is stored in the storage device 9, and the central control unit 8 knows the registered telephone of the called party from the called ID number by using the telephone registration table ( Sixth
(Fig.604).

Central controller 8 connects the calling telephone and the called party registered telephone (605 in FIG. 6). This allows the called telephone to answer, receive a message, or inform the destination.

In this system, since both the telephone and the ID card have a display device, even if the same called party is successively called, they are respectively called, the responses are made on a first-come-first-served basis, and the calling party has already received the call. It is possible to indicate that there is a first-come first-served ringing and to inform the called party that there are multiple calls.
Also, the response may not be on a first-come-first-served basis, but may be a method based on the selection of the called party. In this case, it is necessary that the receiver receives the call ID number and reads the stored state or the button operation specifying the response order with the ID card reader.

In the above embodiment, the call in the same private branch exchange system has been described. For example, in the case of an incoming call from a central office, the exchange responds to the call arriving at the central office interface 4 in FIG. After being connected through the attendant console interface 5, a similar personal call is possible when the exchange holds the line and calls the called party. The only difference is that the exchange is regarded as the caller while the exchange is present, and after the exchange moves to another call operation, the incoming line interface is regarded as the caller.

〔The invention's effect〕

As described above in the embodiment, when a caller calls an arbitrary called party (called party) with a portable receiver such as a pager, if a response is received from the called party, the calling party immediately responds. A call between the caller and the called party is made. On the other hand, if there is no answer, a call is made to a predetermined telephone such as an office telephone to which the called party belongs, and the calling party is called. Since the caller can talk to the person associated with the caller, and thus can request a message or the like to the person associated with the called party, the caller can receive a minimum message notification by telephone. .

Also, when the destination is forwarded, the caller is notified by voice message that the destination has been forwarded, so that the caller can talk without any discomfort and the service to the caller It also has a remarkable effect of improving the performance.
