DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Industrial application field) The present invention has a parent device connected to a wired telephone line, and a wireless telephone connected to the parent device via a wireless line. The present invention relates to a wireless telephone device, and more particularly to a wireless telephone device in which a parent device is provided with a wired telephone connected parent and child, and an extension call can be made between the wired telephone and the wireless telephone.

(Prior Art) Conventionally, this type of apparatus has been configured as shown in FIG.

That is, the parent device 1 includes the wireless telephone connection device 28 and the wired telephone 24, and the wired telephone line 3 and the wireless telephone connection device 28, the wired telephone line 3 and the wired telephone 24, and the wireless telephone connection device 28. In addition to the combination of calls of the wired telephone 24 (extension call), a three-party simultaneous call can be selected.

The wireless telephone connection device 28 is connected to the wireless telephone 2 via a wireless line and to the wired telephone line 3 via a line switch 26. The outline of this operation is as follows.

The signal transmitted from the wired telephone line 3 is used as a modulation input of the transmitter 5 via the line switch 26 (the switch selects the A side at this time) and the hybrid circuit 4. The radio wave modulated by the transmitter 5 is transmitted from the transmission antenna 6 to the wireless telephone 2. On the other hand, a radio wave transmitted from the wireless telephone 2 is received by the receiving antenna 7 and demodulated by the receiver 8. The demodulated signal is transmitted to the wired telephone line 3 via the hybrid circuit 4 and the line switch 26.

The synthesizer 9 outputs a frequency corresponding to the radio channel to the transmitter 5 and the receiver 8.

One of the outputs of the receiver 8 is input to the reception electric field detection circuit 10, and the electric field strength is determined. This circuit is generally called a carrier squelch circuit or a noise squelch circuit. The other output is output as a data signal included in the received demodulated wave, and is input to an identification signal detection circuit 11 for collating an identification signal determined by a combination of the radio telephone connection device 28 and the radio telephone 2 to be collated. . This identification signal is generally called an ID code.

The outputs of the detection circuits 10 and 11 and the demodulated output of the data signal are input to the control circuit 12 and used for connection control. Further, the control circuit 12 performs radio channel control by controlling the synthesizer 9 and performs control such as transmitting a transmission data signal to the transmitter 5 as a modulation input.

On the other hand, the wireless telephone 2 also has a receiving antenna 13 and a receiver 14, and the demodulated output is output to the receiver 15. Also,
The voice input from the transmitter 16 becomes the modulation input of the transmitter 17, and is transmitted as a radio wave from the transmission antenna 18.

The synthesizer 19, the received electric field detection circuit 20, and the identification signal detection circuit 21 are equivalent to those of the parent device 1, and the control circuit 22 controls the wireless telephone 2. The speaker 23 is a sounder that emits a ringing sound when receiving a call.

For internal calls, set line switches 25 and 26 to B respectively.
The above operation is performed in the state set on the side.

FIG. 4 is a flowchart showing a connection control operation procedure for establishing a wireless line between the parent device 1 and the wireless telephone 2, which will be described according to the flowchart.

When the user performs a call request operation (for example, off-hook) to the wireless telephone 2 (step 201),
From the control circuit 22, via the transmitter 17, the transmission antenna 18,
A call signal is transmitted to parent device 1 (step 20).
2). The call signal includes an ID code, and the parent device 1
Then, if the ID code detected by the identification signal detection circuit 10 matches its own, it is determined to be a call signal (step 101), and the communication channel designation signal is transmitted to the wireless telephone device 2 as a response signal (step 101). 102). The call channel designation signal includes not only the ID code but also channel information whose availability has been confirmed in advance.

After that, the parent device 1 and the wireless telephone 2 start switching operation to the communication channel (steps 103 and 203). When the switching is completed, the wireless telephone 2 confirms that the channel is vacant (step 204). Then, a channel switching completion signal is transmitted to notify the parent device that the channel switching has been completed (step 205).

The parent device 1 that has received the above signal issues an instruction to form a communication path to the wireless telephone 2 by the communication start signal (step 104), and also makes a line connection to form the communication path (step 105). .

By the way, in the example of the wireless telephone device shown in FIG. 3, since there are a plurality of line forms as described above, it is necessary to notify the parent device 1 of the distinction between an outside line and an extension when making a call from the wireless telephone 2. There is.

FIG. 5 shows an example of a key arrangement of a general wireless telephone apparatus, and an extension key 31 indicating an extension call is provided.

The operation of the control circuit 22 of the wireless telephone 2 at the time of calling is as follows.
It becomes like the flowchart shown in FIG. That is,
First, it is determined whether or not the extension key 31 is pressed (step 211). If the extension key 31 is pressed, this is stored (step 212). Next, it is determined whether there is an off-hook call request (step 213). If it is stored that the extension key 31 has been pressed (step 214), an extension call indicating that the call is an extension call is made. A signal is transmitted (step 215). If it is determined in step 214 that the extension key 31 has not been pressed, an external line call signal indicating an external line call is transmitted (step 216).

That is, if the user goes off-hook after pressing the extension key 31, it is determined that the call is an extension call. If the extension key 31 is not pressed, it is determined that the call is an outside call. Based on the result of this determination, information indicating the outside line and extension is included in the call signal and reported to the parent device 1, and the parent device 1 stores the information at this time and connects the line (step 105 in FIG. 3). Then, the setting positions of the line switches 25 and 26 are determined according to the above storage.

In the above conventional example, if the user presses the extension key after off-hook, the call signal transmitted immediately after off-hook includes outside line information. Must be sent to switch to the extension side.

(Problems to be Solved by the Invention) As described above, in the above-mentioned conventional device, an outgoing line /
Because the extension information is included, if the extension key is pressed after the connection control operation has been started after off-hook, the external line will be captured once, and then switched to the extension, and traffic on the wired telephone line will be wasted. There was a problem of giving up.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a wireless telephone device that can directly connect to an extension without catching an outside line when an extension key is pressed immediately after off-hook.

It monitors whether an extension connection request has been input.
If an extension connection request is input during the monitoring period by the monitoring unit, the transmission unit transmits the extension connection request from the wireless telephone to the parent device when the connection with the parent device via the wireless line is completed.

According to such a configuration, even when an extension connection request is input after off-cooking in the wireless telephone, if the extension connection request is within the predetermined monitoring period, the extension is directly captured without capturing the external line. Thus, it is possible to prevent an increase in unnecessary traffic on the wired telephone line.

(Embodiment) FIGS. 1 and 2 are flowcharts showing the operation of an embodiment of the radio telephone apparatus of the present invention.

In this embodiment, the hardware configuration is the same as that shown in FIG. 3, and the key arrangement can be the same as that shown in FIG. Hereinafter, FIG.
The operation of this embodiment will be described with reference to FIG.

In this embodiment, the operation of the extension key 31 is monitored from the standby state until the line connection control is executed by the parent device 1.

The monitoring of the extension key 31 is executed by the control circuit 22 of the wireless telephone 2 as a parallel processing of the connection control processing between the parent device 1 and the wireless telephone 2. FIG. 2 shows an example of this parallel processing. That is, the control circuit of the radio telephone 2 is in a state from the standby state until the line connection control is executed in the parent device 1.

In this process, when the operation of the extension key 31 is detected (step 211), the fact is stored in a storage unit (not shown) (step 212). This storage is determined in step 206 of the flowchart shown in FIG. 1. The result of this determination, that is, information on the outside line / extension indicating whether the call is an outside line or an inside line is included in the channel switching completion signal and transmitted to the parent device 1. (Step 206).

The parent device 1 executes the line connection control in step 105 based on the information on the outside line / extension included in the channel switching completion signal. That is, the line switches 25 and 26 shown in FIG. 3 are switched to the A side when the information on the outside line / extension included in the channel switching completion signal indicates the outside line, and when the information indicates the inside line, the line switch shown in FIG. 25 and 26 are each switched to the B side. Note that other operations are performed in the fourth
This is the same as the flowchart shown in the figure.

By the way, the connection control operation normally takes about 1 to 2 seconds from the start (off-hook) to the end (completion of line connection) in consideration of the time such as the data signal length, the operation start-up time of the wireless device, and the channel switching time of the synthesizer. Is common.

Therefore, if the user goes off-hook first for the purpose of calling an extension and then presses the extension key within 1 to 2 seconds, the extension will not be temporarily connected as in the past, but will be directly connected to the extension. Can be connected to
