Abstract

PURPOSE:To surely make a call by registering a telephone number at a slave set side when the slave set is not hooked off for a prescribed time and a caller telephone set enters the telephone number and sending a callout of the registered telephone number automatically with a prescribed pushbutton operation. CONSTITUTION:When a call of a slave set 21 is implemented by an extension telephone set 5 of a cordless telephone system, for example, and when the call destination slave set 21 is not hooked off within a prescribed time, an input command of the telephone number is outputted from a master set 1 or an exchange 4 to the caller 5. When a telephone number is entered from the caller telephone set 5, the data of the telephone number is sent to the master set 1 via the exchange 4 and the telephone number is sent from the master set 1 to the caller destination slave set 21. Then the sent data (telephone number) is stored (registered) at the slave set side and the telephone number is displayed on a display section 7 and the call by the telephone number is made by the operation of a talking request button 8. Thus, the slave set side calls the caller telephone set 5.

Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention is used in a predetermined area such as a golf course, construction site, or factory, and is used in a predetermined area such as a golf course, a construction site, or a factory. The present invention relates to a cordless telephone system configured, and more specifically, to a cordless telephone system in which when a handset is not taken off-hook when the handset is called, the handset later calls the calling telephone.

[Conventional example] In recent years, cordless telephones have been proposed by various manufacturers as new home appliance products. A cordless telephone consists of a connection device <m device) connected to a telephone line and a handset (slave device), and signals such as calls, ID codes, voice communication, etc. are transmitted and received between them using radio waves. Therefore, the connection device is equipped with a radio wave transmitting and receiving function, and the handset also has a built-in radio wave transmitter and receiver. In other words, the other party's voice is converted from an electrical signal to a radio wave signal by the connecting device and sent to the handset. Conversely, a voice signal transmitted by radio waves from a handset is converted from a radio wave signal to an electrical signal by the connecting device, and then transmitted to the other party via the same line.

By the way, the above-mentioned cordless phones come in two types: low power type for home use and low power type for commercial use, but both have a one-to-one correspondence between the base unit and the handset, and it is not possible to use multiple handsets. Can not do it.

Therefore, the base unit may be one, and the slave units may be N (any number), or the base unit may be M (any number), and the slave units may be N.
Cordless telephone systems have been proposed.

[Problem to be Solved by the Invention] However, in the cordless telephone system described in Section 2, if the called handset is not off-hook, for example, if the handset is not home, etc., and the operator of the handset does not perform an off-hook operation, The call line between the calling phone and the handset is not connected. Therefore, the caller has to perform the calling operation (dial operation) repeatedly, and if the person handling the called handset does not go off-hook for a long time, for example, if the caller is away from the handset,
This also results in unnecessary calling operations.

Therefore, the handset may have an answering machine function, but in the case of the cordless telephone system, the answering machine cannot be used because a plurality of handsets use a common extension.

This invention was made in view of the above-mentioned problem, and its purpose is to be able to call the calling telephone later on when the called handset is not off-hook, and to allow the calling handset to call the calling telephone at a later time. Our goal is to provide a cordless telephone system that allows you to:

[Means for Solving the Problems] In order to achieve the above-mentioned objective (T1), the cordless telephone system of the present invention includes a plurality of handsets used within a predetermined area;
placed within the above area, and make calls to and from those slave devices.
At least one base unit that sends and receives signals such as ID codes and voice communications, and an exchange that connects the base unit and the internal telephone by wire are provided. The handset has a function of outputting the telephone number to the exchange, and the handset has a storage means for storing telephone number data from the extension telephone side, a display means for displaying this telephone number, and an extension telephone of the stored telephone number. If the handset called by the above-mentioned JL telephone is not off-hook, the telephone number from the calling extension telephone is transmitted to the called handset through the exchange and base unit. The gist is that the caller extension telephone is called by the call destination handset.

``Function'' - Since the configuration is as described above, when a call is made to a handset using an extension phone of a cordless telephone system, if the called handset does not go off-hook within a predetermined time, the call will be made from the base unit or exchange. The caller is prompted to enter the telephone number. Here, when a telephone number is entered on the calling extension, the data of this telephone number is sent to the base unit via the exchange, and the base unit transmits the telephone number to the called slave unit. . Then, the handset stores (registers) the transmitted data (telephone number), and
The telephone number is displayed, and a call to the telephone number is made by operating the call request button.

[Example] Hereinafter, an example of the present invention will be described based on FIGS. 1 and 2.

1 and 2, a base unit (connection device) 1 is provided in a predetermined area (for example, the grounds of a golf course, etc.), and a cordless phone system handset 2. ．． 22. ...There are multiple p2Ns. The base unit 1 is connected to an exchange 4 via a wired line (extension) 3, and telephones (for example, extension telephones) 5 and 6 are connected to the exchange 4.

The base unit 1 also functions as a wireless controller that calls the slave units 21, 2□, .

It is equipped with an exchange 4 and a wired controller for making same-line connections. Further, the extension telephones 5 and 6 have a function of outputting to the exchange 4 a number corresponding to the corresponding button operation. Furthermore, as shown in FIG. 2, the handsets 21, 2□, .
, a display section (for example, a liquid crystal display section) 7 for displaying the number, and a call request button 8 for calling the telephone with the displayed number. In addition to the above-mentioned number, the display unit 7 also displays the power status, call status, etc.

As a further supplement, the above cordless telephone system:
A duplex system is adopted, and voice communication including various data transmissions within the voice band is performed.

Next, we will explain the operation of the cordless telephone system with the above configuration in a second manner.
The explanation will be given with reference to a partial view of the main body of the slave device in the figure.

First, when the handset 2□ of the ID code (IDOL) is not operated off-hook, for example, the telephone (extension number 2671)
5, a call is being made to the handset 2□, but it is assumed that the operator of the handset 21 is away or does not consciously perform an off-hook operation. Then, when the telephone number (for example, 2671) is inputted on the telephone set 5 after a calling operation for a predetermined period of time, this telephone number is transmitted to the base unit 1 via the exchange 4. 1, the data of the telephone number is transmitted to the called handset 2. After inputting the above-mentioned number, the on-hook operation of the telephone 5 causes the exchange 4 to disconnect the telephone 5 from the main unit 1.

Subsequently, the called handset 21 executes a process (shown in the figure) of temporarily storing and displaying the sending telephone number. Here, when the operator of the handset 2□ operates the call request button 8, the registered number is automatically transmitted. That is, signals are exchanged between the handset 21 and the base unit 1 for normal wireless co-wire connection, and calls to the telephone 5 are made via the base unit 1, so the call signal is sent to the exchange 4. The message is sent to telephone 5 with extension number 2671, and that telephone 5 is called.

In this way, if the called handset 21 is not off-hook for some reason, the telephone number data of the calling telephone 5 is registered and displayed on the handset 2□ side. Furthermore, by operating the call request button 8 of the handset 21, the telephone 5 automatically dials the number, so there is no need for the calling telephone 5 to repeat the calling operation.

In addition, when calling a predetermined handset using the telephone 5,
If the handset is not operated off-hook within a predetermined period of time, the base unit 1 or exchange 4 may send a voice message such as ``The other party is not answering, please enter the phone number you want to call.'' A signal that generates a sound notifying the user is transmitted to the calling telephone 5.

As a result, on the phone 5 side, the vM that you want to make a call.
, just input the call number using the button.

[Effects of the Invention] As explained above, according to the cordless telephone system of the present invention, when a handset is called and the handset is not off-hook for a predetermined period of time, when a telephone number is input on the calling telephone, The phone number is sent to the calling handset via the exchange and base unit, and the handset registers and displays the phone number, and automatically calls the registered phone number by pressing the specified button. Now, the calling phone only needs to enter the phone number (extension number), and there is no need to call the handset again, and it is possible to call the person handling the called handset. If you have the will to do so, it will definitely have the effect of getting you to call.
