The display unit 6 has a display unit 6 also serving as a display unit of a source telephone number.

Since the master unit D1 has the same configuration as the slave unit D2, detailed description of common parts will be omitted. The base unit D1 includes a signal processing unit 10 having a source telephone number detecting unit 10A, a storage unit 11 having an electronic telephone directory parent 11A, and a wireless transmitting / receiving unit 12 also serving as a transmitting unit of the detected source telephone number to the slave unit D2. , A handset 13 for telephone calls, a display unit 14, and a key operation unit 15, and are connected to an external public line L by wire.

Next, the operation of the wireless communication device A will be described. First, a procedure for detecting a source telephone number in base unit D1 using a source telephone number notification service will be described. FIG. 3 is a conceptual diagram illustrating a basic procedure when using the caller telephone number notification service. In the figure, an ID receiving terminal corresponds to a communication terminal device on the service receiving side, here, a master unit D1, and a subscriber line exchange corresponds to a public line exchange.

When a call request is made from any subscriber telephone (calling side) to an ID receiving terminal device (master unit D1) for which a service contract has been made in advance, the exchange changes the polarity of the telephone line on the called side. After the inversion, an ID receiving terminal activation signal is transmitted.
At this time, the calling signal which has been conventionally used is not sent to the called side. Receiving this, the called terminal device, if it can receive the source data such as the source telephone number, receives the call by closing the DC circuit in the terminal,
Sends a primary response signal. When the exchange confirms the primary response signal, it transmits the source data (modem signal) to the called terminal, and upon receiving this, the terminal opens the DC circuit, disconnects the line, and completes the reception. Reply signal.

[0014] In this manner, the exchange transmits the source data to the terminal device which has received the call request from the subscriber telephone, and then transmits the call signal which has been used conventionally. Upon receiving the call signal, the called terminal device sounds a ringing tone to prompt an incoming call, and displays the calling source data of the calling side received earlier at this time on the display.

[0015] Here, when the called terminal equipment judges by looking at the source data, picks up the handset and receives a call, and responds, when the DC circuit is closed again, a secondary response signal is generated. Will be replied. When the exchange receives the secondary response signal, it reverses the polarity, connects the telephone line between the calling telephone and the called terminal, and becomes able to talk (see FIG. 3). (A)-(i)). On the other hand, if the called party does not respond by judging the source data, no secondary response signal is returned and the telephone line is not connected.

The above procedure is executed by the source telephone number detecting means 10A of the master unit D1. As described above, in the base unit D1, it is possible to avoid a prank call by using the caller's telephone number notification service, or to select a call partner at the convenience of the user. In a communication device, this service can be used on the slave device side.

FIG. 4 is a diagram showing an example of a procedure for using the caller telephone number notification service on the slave unit side of the wireless communication device of the present invention. This procedure relates to claims 1 and 2. When the base unit D1 receives an incoming call and detects the caller telephone number using the caller telephone number notification service, it displays the caller's telephone number on the display unit 14 of the master unit D1 as described above, and when the handset 13 goes off-hook, , Close the line. At this time, the base unit D1 stores the source telephone number in the electronic telephone directory parent 11A every time a detection is made or a response is made to the call.

Here, in the case of the present invention, the master unit D1 calls the slave unit D2 simultaneously with the detection of the caller telephone number, and transmits the detected caller telephone number to the slave unit D2. Receiving this, the slave unit D2 displays the source telephone number on the display unit 6 and stores the number in the electronic telephone book 2A. If this telephone number is stored and stored in the slave unit D2 when responding to the source telephone number, unnecessary telephone numbers are not stored.

If it is determined that the other party should respond when viewing the display, when the "outline" button of the key operation unit 5 is operated, a response signal is transmitted to the master unit D1.
The line is closed, and the slave unit D2 is connected to the slave unit D2.
1 allows the user to talk to the called party. In this way, even in the slave unit D2, the source telephone number notification service can be used just like the master unit D1, and the utility value of a wireless communication device such as a cordless master phone is improved.

Further, an electronic telephone book 2A can be created from the received source telephone number, and a telephone number can be displayed using the electronic telephone book 2A.
The electronic telephone book 2A can be created exclusively for a specific member of the family, for example, by using the slave unit D2 exclusively, so that it can be adapted to the personality and necessity of each dedicated person. It is in line with the request. Further, since the electronic telephone directory parent 11A created by the base unit D1 is created and held separately, it can be used as a spare even if the electronic telephone directory 11A becomes unusable due to a failure.

FIG. 5 is a diagram showing an example of a procedure for automatically making a call using the stored source telephone number on the slave side of the wireless communication device of the present invention. This procedure relates to claim 3. In the slave unit D2, when an automatic call is to be made using the stored source telephone number, first, the electronic telephone book 2
From A, the stored telephone numbers are read out and sequentially displayed on the display unit 6. The user of the slave unit D2 looks at the display,
When a caller who wants to make a call is selected with the numeric keypad of the key operation unit 5 and the call button 5A is operated, the slave unit D2 sends a call command to the master unit D1, and the master unit D1 establishes a connection with the slave unit D2. When a call is established to the public line and the line is closed, the slave unit D
In 2, the user can talk with the other party of the selected telephone number via the master unit D1.

Further, the selection of the call destination is made by sequentially inverting and displaying the telephone numbers using a forward key or the like, and at the desired telephone number,
By operating the call button 5A, the selection and the automatic call may be performed simultaneously. As described above, according to the wireless communication device of the present invention, even from the slave unit,
Automatic calling, no need to dial / enter numbers,
It is convenient.

In the above description, a case has been described in which an electronic telephone directory is separately provided in the slave unit. However, such a storage location is not provided in the slave unit, but is provided only in the master unit. When a call is made from the child device, the parent device can be called, the electronic telephone directory of the parent device can be read out and displayed on the child device, and search and calling can be performed. By doing so, the storage unit and the like of the slave unit can be simplified, and the entire slave unit can be reduced in size and weight.

In the above description, the caller ID service mainly provided in Japan has been described. However, the Caller-ID provided in the United States has been described.
The present invention can be applied to services. Cal
In the ler-ID service, the source telephone number is sent to the called side by an FSK signal using the suspension period of the call signal. The called side is provided with a modem for demodulating the FSK signal, so that the calling party's telephone number can be obtained.

[0025]

As can be understood from the above description, according to the wireless communication device of the first aspect of the present invention, a master unit connected to a communication line to perform communication, and a wireless communication with the master unit. The base unit uses the caller's phone number notification service to detect the source phone number sent from the outside line, and calls the detected source phone number to the slave unit. Since transmission is sometimes made to the child device, not only the parent device but also the child device can use the caller telephone number notification service.

According to the wireless communication device of the second aspect,
It is composed of a base unit that communicates by connecting to a communication line, and a slave unit that performs wireless communication with this master unit. The slave unit also receives the source telephone number from the outside line detected by the master unit every time it receives it. To remember
Since the received or memorized source telephone number is displayed, it is possible to create an electronic telephone book unique to the slave unit, and to match the personality and need of the user of the slave unit, and to personalize It meets the needs of the times.
