Abstract

PURPOSE:To provide the radio telephone equipment which can ring the call incoming tone of only the designated slave set by sending a PB signal corresponding to the number of the slave set after a caller pushes a telephone number and performs dial transmission. CONSTITUTION:When a call incoming signal is inputted from the caller to a line connection part 1, a call incoming detection part 3 detects call incoming and informs a control part 7 of it. When the number of times of call incoming reaches a set value, the control part 7 controls a line closing part 2 and closes a line. A voice message for urging the designation of the slave set number is sent from a voice message sending part 5 with the PB signal through the line to the caller. A PB receiver 4 receives the PB signal from the caller and transmits this signal to the control part 7. The control part 7 selects a radio slave set 9 corresponding to the designated slave set number out of a radio slave set group 12 and transmits the call incoming signal from a radio signal transmission/reception part 8 to the slave set 9.

Embodiments of the present invention will now be described with reference to the drawings.

FIG. 1 is a block diagram showing an embodiment of the present invention. This wireless telephone device is composed of a connection device (master station) 11 connected to the line connection unit 1 and a wireless slave unit group 12 including a plurality of slave units wirelessly connected to the master station.

The master station 11 includes a line closing unit 2, an incoming call detecting unit 3, a 2-line to 4-line converting unit 10, a PB signal receiving unit 4, and
The voice message sending unit 5, the incoming signal generating unit 6, the control unit 7, and the wireless signal transmitting / receiving unit 8 are included.

The incoming call detecting section 3 detects an incoming call signal from the line from the calling party.

The line closing unit 2 closes the line when an incoming call is detected by the incoming call detecting unit 3.

The 2-line to 4-line conversion unit 10 separates the transmission and reception.

The voice message sending unit 5 prompts the caller to specify the cordless handset number by the PB signal, and sends a voice message to the caller to notify the caller to the line.

The PB receiver 4 receives the PB signal sent from the calling party, and converts the PB signal into a code corresponding to the extension number.

The incoming signal generator 6 sends an incoming signal individually for each child device.

The wireless signal total receiving unit 8 performs wireless transmission / reception with the child device such as calling to the child device 9.

The control unit 7 controls the entire master station and
The code from the PB receiver 4 is analyzed and the designated slave unit is called.

Next, the operation of this embodiment will be described with reference to FIG. 2 is a flowchart showing the control of the control unit 7 of this embodiment.

When an incoming signal from the caller is input from the telephone line connected to the line connection unit 1, the incoming call detection unit 2 detects that there is an incoming call. The incoming call detection unit 2 notifies the control unit 7 of the incoming call detection. When the incoming call is notified (step S1), the control unit 7 counts the number of incoming signals (step S2), and when the number of incoming signals reaches a predetermined number (step S3), the line closing unit 2 is activated. It is operated and the line is closed (step S4). The control unit 7 causes the voice message transmitting unit 5 to transmit a predetermined message to the line (step S5), and prompts the caller to transmit the slave unit number by the PB signal. When the caller sends a PB signal corresponding to the cordless handset number to the line, the PB signal is received by the PB receiving unit 4, converted into a code corresponding to the dial number, and then the control unit 7
Send to. When this code is input (step S6), the control unit 7 analyzes the input code and determines which child device is designated (step S7). further,
Wireless slave unit 9 corresponding to the slave unit number designated by the PB signal
In order to make a call, the incoming signal generator 6 generates an incoming signal (step S8), and the wireless signal transmitter / receiver 8 transmits the incoming signal to the designated handset to make a call and make an incoming call (step S9). That is, only the designated child machine sounds the ring tone. When the caller can make an incoming call to the desired child device (step S10), the control unit 7 sends a predetermined message from the voice message sending unit 5 to the line and calls the caller. That there is an incoming call (step S1)
1). In this way, the caller can call the desired child device.

In the above embodiment, the PB signal transmission request to the calling party and the incoming call notification to the calling party are made by the voice message. However, the voice message transmitting section is replaced with the signal sound transmitting section, and the signal is transmitted. It can also be done by sound.

In the above embodiment, one incoming signal generator 6 is provided in the master station 11. However, as shown in FIG. 3, the incoming signal generator 13 may be incorporated in each slave unit. Good. In this case, the control unit 7 sends a control signal for operating the incoming signal generation unit 13 inside the wireless slave unit 9 from the wireless transmission / reception unit 8.

[0024]

As described above, in the radiotelephone device of the present invention, the caller can select the cordless handset with which the caller wants to make a call, so that wasteful work such as telephone transfer is not required and convenience is improved. Has the effect. Further, there is no need for incoming call processing for all the wireless slave devices, and it is possible to effectively use radio waves.
