 Next, the operation of the embodiment having the above configuration will be described.

(1) incoming call to the wireless telephone 13 First, the operation will be described with reference to FIG. 7 in the case of incoming via the existing exchange 10, for example, in radio telephone 13 of extension 13X _1.

In this case, if there is an incoming call from the existing exchange 10,
As shown in FIGS. 7 (a) and 7 (b), an extension call signal having a ringing pattern of 16 Hz for 1 second and a pause for 2 seconds is transmitted and arrives at the curve interface 111.

In addition, in the case of an outside line incoming, an outside line calling signal such as a ringing pattern of 1/4 second, a 1/4 second pause, a 1/4 second ringing, and a 1/4 second and 2 second pause ringing pattern is transmitted. .

Ringer detection circuit 1 of incoming curve interface 111
11c detects the pattern of the incoming bell ringing signal and sends a detection signal corresponding to the ringing pattern to control unit 110.

The control unit 110 determines whether the wireless telephone (1
3X ₁ ) reads the wireless zone in which it is located, selects the wireless line interface 113 corresponding to the control station of the wireless connection device 12 located in that wireless zone, and then the wireless telephone (13X ₁ )
The signal of the identification number is transmitted.

The control unit 110 also selects the wireless circuit interface 1
A control signal corresponding to the bell ringing pattern from the existing exchange 10 is sent to the ringer generation circuit 113a of 13 and the ringer generation circuit 113a turns on the signal synthesis unit 113c by the control signal from the control unit 110, and (1 ) PB signal, (2) digital signal, (3) loop current inversion, or (4) loop current on / off to generate a bell ringing signal (call control signal) and output it to the wireless connection device 12.

7 (b) and 7 (c), the ringer generation circuit 113a
The case where the bell ringing signal is output by the PB signal is shown.

The control unit 120 of the wireless connection device 12 receives the call signal and the like via the line interface 122 and the control signal transmitter / receiver 123, and according to the control signal data of the wireless line connection file 125a, the wireless wireless telephone (13X ₁ ) The signal of the identification number and the call control signal as shown in FIGS. 7 (c) and (d) are generated and transmitted via the wireless transceiver 121.

The wireless telephone 13 receives the signal of the identification number of the wireless telephone (13X ₁ ) and the call control signal via the wireless transceiver 131, compares the received identification number with the identification number of the wireless telephone ID file 138b, and matches them. controller of the radio telephone (13X ₁₎
130 turns on its transmitter / receiver 132.

Therefore, as shown in FIG. 7 (d), the transmission / reception unit 132 generates a voice according to the ringing pattern for calling from the existing exchange 10 by the call control signal from the wireless connection device 12.

That is, the ringing pattern of the call signal from the existing exchange 10 is sequentially sent to the wireless telephone (13X ₁ ) through the control stations of the wireless line control device 11 and the wireless connection device 12 in different signal formats and the same ringing pattern, wireless telephone (13X ₁₎
The call signal from the existing exchange 10 is reproduced with the same ringing pattern by the receiver of the handle set 132a and the calling belt (not shown).

Next, when the wireless telephone (13X ₁ ) goes off-hook, the data is sent to the wireless line control device 11 via the control station of the wireless connection device 12, and the control unit 11 of the wireless line control device 11 is sent.
0 controls the matrix switch 114, and the control unit 120 of the wireless connection device 12 turns on the voice control unit 124 to form a speech path between the calling side telephone and the wireless telephone (13X ₁ ).

(2) Calling from the wireless telephone 13 Next, an operation when calling from the wireless telephone 13 to a station line or another wireless telephone 13 will be described.

Hook switch 134 when wireless telephone 13 is off-hook
When turned on, the control unit 130 generates a calling signal by the connection sequence and control signal of the wireless line connection file 135, and also generates and adds the identification number of the wireless zone currently located in the wireless zone number file 138c. Then, the data is transmitted via the wireless transceiver 131.

The control unit 120 of the control station of the wireless connection device 12 in each wireless zone compares the identification number of its own wireless zone in the station data file 125b. , A call response signal and a signal designating a communication channel are transmitted to switch to the communication channel, and the wireless connection device becomes a communication station.

When the control unit 130 of the wireless telephone 13 sends a channel switching signal, the wireless connection device 12
And the control unit 130 of the wireless telephone 13
However, when the interference detection completion signal is transmitted when there is no interference with the adjacent wireless zone, a calling signal is transmitted to the wireless line control device 11. Upon receiving the calling signal, the wireless line control device 11 puts the subscriber line into a closed loop and sends the calling signal to the existing exchange 10.

Next, the control unit 110 of the wireless line control device sends a call response signal to the wireless connection device 12 and the wireless connection device 12
The control unit 120 turns on the voice control unit 124 and sends a voice circuit activation signal to the wireless telephone 13. Wireless phone
The control unit 130 of the transmission / reception unit 132 receives the voice circuit activation signal,
Turn on.

Therefore, as in the case of the above-mentioned incoming call, the dial tone sent from the existing exchange 10 to the wireless telephone 13 through the closed loop is reproduced as voice by the receiver of the handset 132a, and the caller is called the existing exchange 10. We can know the closed loop of.

Next, the control unit 130 of the wireless telephone 13 uses the dial key 1
When a dial number is inputted from 13, a dial code is converted into a dial code, and a signal indicating the dial signal system set by the PB / DP switch 136 (for example, PB signal is “0”, DP
The signal is transmitted to the wireless connection device 12 with “1” added.

The wireless connection device 12 converts the dial code into a dial signal of DP signal system or PB signal system by a signal indicating the dial signal system, and sends it to the existing exchange 10 through the closed loop. The existing exchange 10 sends a ring back tone to the wireless connection device 12 via the closed loop, the wireless connection device 12 converts the ring pack tone to the wireless signal and sends the wireless signal to the wireless telephone 13, and the called telephone When you answer the call, the call becomes available.

As described above, according to the present invention, the wireless line control device detects the pattern of the bell ringing signal from the switching connection device and generates the bell ringing signal having the same pattern as the bell ringing pattern to establish the wireless connection. The device generates a wireless signal with the same pattern as the bell ringing signal from the wireless network controller, and the wireless phone is configured to reproduce the wireless signal from the wireless connection device as voice. The bell rings in the same pattern as the ringing sound of the bell from the device, and therefore it is possible to know what state the bell ringing indicates to the called party.
