Thus, the reorigination during the alarm display is started by the operation of the start switch 201 only, and the reorigination applied while moving a mobile equipment is moved toward a master set is made very simple and the ease of handling is attained.

Description

[Detailed Description of the Invention] [Objective of the Invention] (Field of Industrial Application) The present invention is a multi-channel access system that detects an empty radio channel among a plurality of radio channels and transmits and receives voice or data. The present invention relates to a wireless telephone device.

(Prior Art) Conventionally, the device consists of a parent device connected to a wired line and a mobile device connected to the parent device via a wireless line. A multi-channel access type telephone device that detects a desend channel based on the received field strength, transmits and receives information on the vacant communication channel and each identification information on one control channel, and connects the master device and the mobile device. Are known.

FIG. 2 is a block diagram showing the conventional configuration of a mobile device with such a configuration, which can be roughly divided into radio sections 101. Control 20 section 102. Operation unit 1032 display unit 104. It consists of a handset 105.

The radio unit 101 forms a communication path using a front line with a parent device (not shown), and includes a transmitter 111, a transmitting low frequency modulator 112 . Transmit data modulator 113. Synthesizer If114. Received data demodulator 115. Reception f1116

FIG. 4 is a flowchart showing the operation when transmitting light from a mobile 11+ machine, in which the user of a mobile vJ machine
Call initiation switch 20 for making a call (not shown)
1 is turned on, the control circuit 102 recognizes this,
Controls the oscillation frequency of the synthesizer 114 on channel 0 (
C-CH), set the receiver 116 to the operating state, and receive radio waves on the control channel 0 (
Steps 300 and 301) Then, the receiver 116 detects the field strength of the radio waves received by the field strength detection signal from the signal line 118, and if there is no received field strength above a certain level, the control channel is deemed to be empty. Step 302>, the transmitter 111 is put into operation, furthermore, the identification code information assigned to itself is modulated by the transmission data modulator 113 and inputted to the transmission R 111, and the transmission signal containing this identification code information is sent to the parent device. (not shown) (step 303).

When the parent device receives an optical signal from the mobile device, it determines whether the identification code information therein matches the identification code information assigned to vj in advance, and if it matches, it sends a message to the mobile device. What about that? ! ! ? send back a signal. This response signal contains identification code information and communication channel (S-OH>
Contains specification information.

The response signal from the parent device is received by the reception tF 1116, but the identification code information therein is transmitted to the reception data demodulator 115.
The signal is demodulated and input to the control circuit 102. Control circuit 1
02 detects whether the identification code information from the parent device matches its own, and if so, switches the optical amplification frequency of the synthesizer 114 to the frequency of the communication channel specified by the parent device, The transmitter 111 and the receiver 116 are set to enable transmitting and receiving operations on this communication channel 11.

In response, the parent device also switches the frequency of its transmitter/receiver to the frequency of the communication channel designated by itself after a certain period of time after returning the response signal.

As a result, the mobile IJJIffi and the parent v2 device are connected through the communication channel specified by the parent device.

When a dial number is input from the control unit 103 in this state, the control circuit 102 inputs the dial number to the transmission data modulator 113 to modulate it, and then transmits it from the transmission 11111. The parent device that received this dialed number sends it to the exchange (not shown) via the wired telephone port S.
The telephone at the other end indicated by the dialed number is called, and when the telephone at the other end answers, a communication path with the mobile device is established.

Therefore, when voice is input from the transmitter (MIC) of the handset 105, the voice signal is transmitted to the transmitting low frequency modulator 112.
After being modulated by the transmitter n111, it is sent to the destination telephone via the parent device and the wired telephone line.

On the other hand, the voice signal from the other party's telephone is received by the receiver 116 and then generated from the handset (RFC) of the handset 105.

Thereafter, when the call ends and the termination switch 202 is operated, the control circuit 102 detects that the termination switch 202 has been operated and stops the operation of the modulator 112 and demodulator 117. A termination signal is transmitted to the parent device via the transmission data modulator 113, and transmitted to the sliding door n 1
11 d3 and the operation of the receiver 116 are stopped to return to the initial standby state.

The above is normal operation, but for example, when the distance between the parent device and the mobile device is large and the radio waves cannot reach each other, even if an optical signal is sent from the mobile device, it is not received by the parent device. A situation arises where it is not possible. Therefore, after turning on the receiver 116 and transmitting a transmission signal, the mobile device monitors whether or not the control channel radio wave or response No. 13 from the parent device is received within the time limit (step 305).
If the time limit is exceeded, it is determined that the emitted radio waves cannot be received due to the above condition or fading between mobile devices, and the display unit 104 indicates that the call conditions are not satisfied. It is displayed that there is no such thing and an alarm is issued (step 306).

This alarm is issued for a certain period of time (for example, about 10 seconds), and when this certain period of time has elapsed (step 308),
The W report display is stopped (step 309), and the initial standby state is returned.

If it becomes necessary to immediately retransmit while this alarm display is being displayed, the alarm display can be stopped before the display period expires by operating the termination switch 202.
T! (Step 310), after this, the call start switch 2
By operating 01 (step 300), re-transmission becomes possible. That is, in order to make a re-transmission when the call conditions are not met, by operating both the termination switch 202 and the call start switch 201 in sequence, a state is established in which the re-transmission is possible.

(Problems to be Solved by the Invention) As mentioned above, in the conventional mobile network, in order to immediately perform a reconfirmation when the call conditions are not met, it is necessary to operate both the end switch 202 and the call start switch 201. There is a need.

However, since the user must perform the above operations while moving the mobile device closer to the parent device, there is a problem in that the operation is extremely troublesome and inconvenient to handle.

SUMMARY OF THE INVENTION An object of the present invention is to provide an S-less telephone device that allows re-transmission with simple operations.

[Configuration of the north gate] (Means for solving the problem) The present invention includes a detection means for detecting that the call start switch is operated when the call condition is not satisfied. The device is configured to restart transmission and reception of signals for forming a call based on the detection result of the detection means.

(Function) If the call start switch is operated while the call condition is not being met and the call start switch is operated, the detection means detects this and restarts the reoccurrence@operation. Therefore, it becomes possible to make a re-call simply by operating the call start switch, which simplifies handling.

(Embodiment) FIG. 1 is a flowchart showing an embodiment of the present invention, and the hardware configuration is the same as that in FIG.
A function is provided to detect whether or not the call start switch 201 is operated when the display section 104 is displaying a warning that the call conditions are not met, and if the call start switch 201 is operated, For example, even during the display period of the alarm display, the receiver 116 is immediately put into the operating state and shifts to the transmitting operation.

By doing so, it is possible to start a re-call while the alarm is being displayed by operating only the call start switch 201. Therefore, the re-transmission operation performed while moving IJIJ fl toward the parent device becomes extremely simple, and handling becomes convenient.

In addition to situations where the call conditions are not met, there are cases where the distance between the parent device and the mobile device is too far, and there are also cases where the call channel or control channel is busy. It is possible to display a warning even in such a state, and to make it possible to make a call again by operating the call start switch.

[Effect of the Invention] As explained above, according to the present invention, the transition flJth and 11th
Since it is possible to start a re-call in a state where the call conditions to the 18th station have not been established by operating only the call start switch, it is extremely easy to perform the re-call operation while moving the portable vJ machine. This has the effect of making handling convenient.
