DETAILED DESCRIPTION OF THE INVENTION

[0001] The present invention relates to a radio telephone apparatus capable of making a telephone call between slave units .

[0002]

2. Description of the Related Art Conventionally, when a call is made between slave units of a wireless telephone system, a call channel used once is released after a predetermined time elapses from the viewpoint of effective use of frequency, and thereafter, reconnection is performed. I needed to.

[0003]

However, in the above-mentioned conventional example, since the communication channel is released after a predetermined time, there is a disadvantage that a momentary interruption of a temporary call occurs and the call is interrupted.

[0004] The present invention is used in a call state between slave units.
It is an object of the present invention to provide a wireless telephone device that can be used without making a user aware of an instantaneous interruption of a call between slave units .

[0005]

FIG. 1 is a block diagram showing the configuration of a wireless telephone device according to an embodiment of the present invention.

The radio telephone apparatus according to the present embodiment includes a radio frequency unit 101 for transmitting and receiving a radio signal, a signal processing unit 102 including a modulation unit for modulating a digital signal to be transmitted, and a demodulation unit for demodulating a received signal into a digital signal. A time-division processing unit 10 that slots a transmission signal for time-division transmission and sends the received time-division signal to codec 104 and control unit 105.
And 3.

A codec 104 encodes an analog audio signal and sends the encoded signal to a time division processing unit, and converts the encoded signal from the time division processing unit into an analog signal.
Receiving the notification from the timing means 106,
7, a control unit 105 that controls the high-frequency unit 101 and the signal processing unit 102 and controls each unit of the wireless telephone device even during normal operation.

[0010] Further, a timer 106 for measuring a predetermined time from the start of the call, a sound generator 107 for notifying the user, and a power supply 108 for operating the wireless telephone device.
, A microphone 109 for inputting voice, a receiver 110 for outputting a received signal, a keypad 111 for inputting various information such as dial data, and an antenna 1 for transmitting and receiving radio waves
And 12.

FIG. 2 is a block diagram showing a configuration of a wireless telephone system accommodating the above-described wireless telephone device in the present embodiment.

As shown, the main components of this system are:
An external line interface 201 that accommodates a plurality of external lines from a public line, a line control unit 202 that controls connection between a plurality of external lines and a plurality of extensions, a wireless extension interface 203 that accommodates a plurality of wireless extensions, and an extension line Extension interface 204.

The telephones 205, 206, and 207 are various types of wireless telephones accommodated in the wireless extension interface 203, and each has the configuration shown in FIG. The telephone 208 is an extension telephone housed in the extension interface 204 and connected by wire.

FIG. 3 is a flowchart showing the operation of the present embodiment, and FIG. 4 is an explanatory diagram showing a sequence when making an extension call in the wireless telephone device.

In the system shown in FIG. 2, it is assumed that a telephone call is made using an inter-unit communication mode for an extension call in the system, and a telephone call is made through a main unit for an outside call.

First, in the standby state, the wireless telephone device monitors the communication channel between the slave units (S30).
1). If there is an incoming call notification (S302), the timer 106 is set to the operating state (S307), and then the wireless telephone device is set to the talking state according to the sequence shown in FIG. 4 for making an extension call (S309). .

When the call disconnection operation is performed from the call state (S310), the call is disconnected (S31).
5) The notification of the lapse of 3 minutes is sent from the timing unit 106 to the control unit 10.
When the value is set to 5 (S311), the sound generator 107 is sounded and the signal path to the receiver 110 is switched from the codec 104 to the sound generator (S312).

At the same time, the communication channel is disconnected once,
According to the sequence for making an extension call of the wireless telephone device shown in FIG. 4 again, the communication state is set (S313). And
When the communication state is established, the timer 106 is reset, and the signal path to the receiver 110 is switched from the sound generator 107 to the codec 104 (S314).

If there is no incoming call notification in S302, the private control channel is monitored (S303). If there is incoming communication (S304), processing is performed so that the wireless telephone device communicates with an outside line via the wireless extension interface 203.

If there is no incoming call notification in S304, the key operation of the wireless telephone device is monitored. If there is an extension calling operation (S305), the timer 106 is operated (S308), and FIG. In accordance with the sequence when an extension call is made by the wireless telephone device shown in (1), an extension call state is set, and the following processing is the same as the processing when an extension arrives.

When there is an outside line calling operation (S3)
06) The wireless telephone device is connected to the wireless extension interface 20
The processing is performed so as to communicate with an outside line via 3. If there is no key operation, the process returns to S301 to monitor the incoming call notification.

Next, a sequence for making an extension call of the wireless telephone device shown in FIG. 4 will be described.

The sequence shown in FIG.
This is a standard sequence for direct communication between slave units shown in D28. The calling handset sends out a calling signal, and when the called side detects, the called side sends out a synchronization signal, and the calling side sends out a synchronization signal. The called party rings the ringer and waits for a response. When there is a response, a response signal is transmitted to the transmitting side, and after exchanging the TCH idle burst signal, the communication is started.

In the above embodiment, FIG.
Although the clocking means 106 and the sounding means 107 have been described as being independent from each other, a similar effect can be obtained with a configuration integrated with the control unit 105.

[0025]

According to the first aspect of the present invention, communication between slave units is achieved.
After a predetermined period of time in the talk state, the call channel is disconnected.
Therefore, it is possible to make effective use of the frequency for calls.
The call again.
And from disconnecting the call channel to reconnecting
For a predetermined period of time
Is notified to the user that the
Make calls between slave units without making the user aware of momentary interruption
The effect that it can be made to play is produced. Claim 2
According to the invention, the predetermined time elapses in the handset communication state.
The call channel is disconnected every time you use
Frequency can be used effectively,
State, so you can resume the call,
The above-mentioned sound generation means from disconnection of the communication channel to reconnection
Is pronounced, so make the user aware of the momentary
Without having to make calls between slave units.
It works.
