Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to an incoming call display method for telephone equipment, and particularly to a telephone line where caller number information (so-called ID information) is sent along with a ringing signal when an incoming call is received. This relates to an incoming call display method for telephone equipment used in

(Background of the Invention) For example, as a method for preventing prank calls, threatening calls, etc., there has conventionally been a double number system. In this system, in addition to the regular phone number that is publicly available to subscribers, a second phone number that is disclosed only to specific people is set, and the second phone number can be changed depending on the will of the person receiving the call.
However, there is a good chance that the second phone number will be known to the public.
Also, it is not effective against prank calls dialed at random.

By the way, due to digitalization of telephone lines, caller's telephone number information (hereinafter referred to as ID information)
A service that sends a caller to the called party has reached the stage of practical use, and if this service is used to display the caller's phone number on the phone, the called party will be able to confirm the caller and decide whether to answer or not. Since it is possible to determine
This is effective against the aforementioned prank calls, etc.

However, from the phone number, the other party (caller)
There are very few cases where it is possible to determine the caller ID, and it is necessary to check the displayed caller ID using, for example, a phone number memo.The confirmation process is troublesome and the response is delayed due to the confirmation time, so in many cases the caller ID cannot be determined. Therefore, the display of the caller number using the ID information is effective, but not very effective.

(Object of the Invention) In view of the above background, it is an object of the present invention to provide an incoming call display method that allows the called party to immediately determine the name of the caller to whom a response must be made.

(Summary of the Invention) For the above purpose, the present invention provides a terminal device, such as a telephone or a button telephone device, that is connected to a telephone line (the telephone line to which the ID information is sent), a telephone number that is important for response. A memory is set up in which correspondence with the subscriber name is registered, and an ID is sent when a call is received.
The information is compared with the telephone number registered in the memory, and if there is a matching telephone number, the subscriber name is displayed on the display of the terminal device. Furthermore, telephone numbers are registered in the memory in ranks according to their importance, and incoming calls are displayed according to the rank as well as the subscriber's name, which not only eliminates prank calls but also makes it easier to respond. This makes it possible to judge the urgency of necessity more accurately.

(Configuration of Embodiment) The drawing is a block diagram of an example in which the present invention is implemented in a telephone set.

As shown in the drawings, the telephone according to the embodiment of the present invention includes a communication path system including a communication circuit network 1, a dial 2, a handset 3, etc., an incoming call detection circuit 4, a CPU 5,
It consists of an incoming call display system consisting of a memory 6, a ringtone indicator 7, a display etc. indicator 8, etc., and the telephone line L is connected to the above communication path system via the normally open contact side of the switch 9, and via the normally closed contact side. and are respectively coupled to the incoming call display system. Note that the telephone line L is a type of telephone line in which ID information is sent together with a ringing signal when a call is received.

Since each part of the call path system is constructed in the same manner as a conventional telephone, a detailed explanation will be omitted, and each part of the incoming call display system will be explained below.

The incoming call detection circuit 4 is a circuit that receives and detects a calling signal and ID information from the telephone line L.

CPU5 performs general control of the phone.
It usually consists of a one-chip microprocessor. Regarding the present invention, the CPU 5 performs control from the time an incoming call occurs until the caller's name is displayed.

The memory 6 is for registering telephone numbers and subscriber names (individual names, corporate names, etc.).In telephones that do not have a means for inputting characters other than numbers, such as ordinary telephones, a separate means is required. A read-only memory (ROM) in which the telephone number and subscriber name are written in advance is used. If the terminal device has input means for various characters, such as a button telephone device, for example, a write/read memory (RAM) may be used in the memory 6 so that the registered contents can be changed at any time. You can also do it.

There are two methods for registering telephone numbers and subscriber names in the memory 6: one is to register all telephone numbers with the same weight, and the other is to rank them according to their importance and register them by rank.

Further, registration in the memory 6 is generally limited to people with whom one frequently contacts by telephone, such as business partners, workplaces, relatives, and acquaintances, and the number of such contacts is usually 100 or less. Therefore, the memory 6 is not required to have a large capacity, and in particular, as mentioned above, the memory 6 is not required to have a large capacity.
When using the memory (usually RAM) in the exchange control device, it is also possible to use free space in the memory that is being used elsewhere.

In addition, as the memory 6, in addition to normal IC memory,
Any type of memory can be used, such as a disk type external memory.

The incoming call indicator 7 audibly displays an incoming call when there is an incoming call, and is constituted by, for example, a so-called tone ringer.

The display 8 visually displays the caller's name as a specific name when a call is received, and is composed of, for example, a liquid crystal display board that displays characters using a combination of dots. In addition, in the system that ranks the telephone numbers registered in the memory 6 as described above, the display 8 includes symbols, characters, etc. that indicate the rank of the caller in addition to the caller's name. It may be displayed.

Each part of the incoming call display system explained above is necessary for each telephone in the case of a telephone that is directly connected to the telephone line L. , O, the incoming call detection circuit 4 is connected to the telephone line L for each interface (office line trunk, etc.), the CPU 5 and memory 6 are connected to the central control unit, and the incoming call detection circuit 4 is connected to the incoming call tone display 7 and to the central control unit. A display 8 is provided for each telephone.

Although not shown in the figure, a voice synthesis circuit may be provided in place of or in conjunction with the display display 8 to display the caller's name audibly through voice synthesis (i.e., through the speaker of the ring tone display 7). It can also be configured to display (by)

(Operation of the Embodiment) When an incoming call is received and a calling signal and ID information are sent to the telephone line L, the calling signal and ID information are input to the incoming call detection circuit 4 via the normally closed contact side of the switch 9. Detected. When the CPU 5 reads an incoming call from the incoming call detection circuit 4, it compares the ID information received from the telephone line L with the telephone number registered in the memory 6, and the ID information matches one of the registered telephone numbers in the memory 6. Then, the CPU 5 reads out the subscriber name corresponding to the registered telephone number from the memory 6 and displays it on the display 8. At this time, ID information, that is, the subscriber's telephone number (caller number) may also be displayed. Further, at this time, the ringtone display 7 is sounded to audibly indicate the incoming call.

Furthermore, if the ID information received from telephone line L is not included in the registered telephone number in memory 6,
The CPU 5 displays only the ID information, that is, the caller number, on the display 8. When receiving a call from a non-registered subscriber, the audible display by the ring tone display 7 may include, for example, changing the volume of the called party (generally lower than the volume when receiving a call from a registered subscriber), or changing the intermittent ringing frequency. Alternatively, it may be convenient to change the tone color so that the form is different from that when receiving a call from a registered subscriber.

In addition, if phone numbers and subscriber names are registered in memory 6 by rank, CPU 5
The rank of the telephone number that matches the ID information is also identified, and the ringtone display 7 and/or the display display 8 display different ranks for each rank. The display by rank on the ring tone display 7 can be done by changing the intermittent cycle, volume, tone, etc., and the display by rank on the display display 8 can be done by specifically displaying characters indicating the rank, flashing a specific character, etc. Let's do it.

Further, according to the present invention, it is possible to easily regulate responses according to time zones.

That is, when the CPU 5 determines whether to restrict responses based on a command from the dial 2 or a time signal from a timer (not shown), the ring tone display 8 indicates that an incoming call is not received from a subscriber registered in the memory 6. This control is extremely effective during times such as late at night.

In addition, when the present invention is implemented in a private branch exchange device such as a key telephone device, verification of ID information and registered subscriber, conversion from telephone number to specific subscriber name, etc. are performed within the exchange control device. , data indicating the results will be sent to the telephone.

(Effect of the invention) As explained above in detail, the present invention
Information about registered subscribers is converted into a specific subscriber name and displayed on the terminal device, and the registered subscribers are ranked and incoming calls are displayed according to rank, so the person receiving the call can instantly recognize the name of the subscriber. It is possible to determine the name of the caller, prevent prank calls, etc., or accurately judge the urgency of the need for a response.
The present invention has many advantages and its effects are quite significant.
