The call waiting unit controlled by a user to set up a call is available when a mobile device is used to make a call. 10), a call standby state for conducting a call by the control of the dial unit 20, the call standby unit 10 or the predetermined button of the dial unit 20 consisting of the number buttons of 0-9 and # and * function buttons If required, the control unit 30 for controlling the function of the radio telephone according to the phase synchronization unit 40, which is controlled by the control unit 30 to fix the channel for radio transmission and reception between the fixed device and the portable device of the radio telephone, The wireless relay unit 50 relays radio transmission and reception between the fixed device and the portable device using the channel fixed by the phase synchronizer 40, and the wireless device between the fixed device and the mobile device through the wireless relay unit 50. Wireless When the scene is made, the voice amplifier 60, which is controlled by the control unit 30 to amplify the sound (here, a dial tone or tone signal) provided from the wireless relay unit 50, and the amplified tone which is amplified by the voice amplifier 60 It consists of a handset 70 for outputting to the user.

The transmitting device of the portable telephone apparatus configured as described above is driven as follows.

First, the call waiting unit 10 is configured as an input terminal such as a button and is controlled when the user wants to perform a call using a portable telephone handset and outputs a corresponding signal. That is, when the user wants to make a call using the mobile device and the user controls the button corresponding to the call waiting unit 10 (when the button is turned on), the connection request between the mobile device and the fixed device for the call ( Or a signal (call waiting state request signal) corresponding to a call connection is output. The call waiting unit 10 is similar to that provided in the existing portable device, and the signal output according to the operation of the call waiting unit 10 may be implemented in a 'high' or 'low' state. The signal output from the call waiting unit 10 is transmitted to the control unit 30.

The dial unit 20 is configured to perform the same function as the call waiting unit 10 described above with a predetermined button among the number buttons 0 to 9 and the available buttons of '#' and '*'. Accordingly, the dial unit 20 performs the same function as the existing one except that the above-described predetermined button is controlled. However, when the above-described predetermined button is controlled, the dial unit 20 requests a connection between the portable device and the fixed device for the call. The corresponding call waiting state request signal is output to the controller 30. The predetermined button may be defined as a combination of at least one function button. For example, one 3-digit button may be defined as the above-described predetermined button, or '3 # *' in which 3, # and * function buttons are combined may be defined as the predetermined button.

When the call waiting state request signal according to the control of the predetermined button of the call waiting unit 10 or the dial unit 20 is applied, the controller 30 fixes a channel between the portable device and the fixed device, and makes a dial tone to the portable device. Controls the function of each component of the cordless phone. That is, the call waiting unit 10 is recognized as being turned on as described above by the signal transmitted from the call waiting unit 10 or the signal transmitted from the dial unit 20 is recognized as a predetermined button controlled. First, the phase synchronizer 40 is controlled.

When the control signal is applied from the control unit 30, the phase synchronizer 40 is driven such that a channel for wireless transmission and reception is fixed between the portable device and the fixed device of the wireless telephone. As a result of the driving, if the channel is fixed, the fixed channel information is provided to the wireless relay unit 50.

The wireless repeater 50 performs wireless transmission / reception processing between the mobile telephone handset and the fixed device using the channel information provided from the phase synchronizer 40. When the channel information is applied from the phase synchronizer 40, Send a dial tone to your mobile device. The transmitted tone is applied to the voice amplifier 60.

The voice amplifier 50 is controlled by the controller 30 to amplify a signal transmitted from the wireless relay unit 50 to a predetermined value. As described above, the voice tone is transmitted from the wireless relay unit 50. When it is transmitted, it is amplified to a predetermined value and output. The output dial tone is transmitted to the handset 70 of the portable device.

The handset 70 is composed of a handset that delivers a user's voice signal to the other party and a handset that provides a voice signal to the user. As described above, when the dial tone is transmitted from the voice amplifier 50, the user can recognize the voice signal. To print it out.

FIG. 2 is a flowchart illustrating a method for transmitting a wireless telephone portable device according to the present invention, which will be described below with reference to the apparatus shown in FIG.

That is, in step 200, the controller 30 checks whether a call waiting state is requested. Here, the call waiting state means a state in which a channel for radio transmission and reception is fixed between a portable device and a fixed device of a radio telephone for a call to ring a ringing tone. As a result of the check, if the call waiting state is not required, the controller 30 returns to step 200. However, if the call waiting state is required, the flow proceeds to step 202.

In operation 202, the controller 30 checks whether the call waiting state request is made by the operation of the call waiting unit 10. As a result of the check, if it is not made by the operation of the call standby unit 10, the process proceeds to step 204.

In step 204, the controller 30 checks whether a call waiting state is required by the operation of the dial unit 20. FIG. As a result of the check, if it is not due to the operation of the dial unit 20, the process returns to step 200 without performing the call waiting state.

However, if the call waiting state is requested by the operation of the dial 20, or the call waiting state is requested by the operation of the call waiting unit 10, as a result of the check in step 204, The controller 30 proceeds to step 206.

In step 206, the control unit 30 attempts to connect the channel so that the channel for radio transmission and reception between the portable device and the fixed device is fixed by controlling the phase synchronization unit 40. As a result of the channel connection attempt, if the corresponding channel is not connected (or the channel is not fixed), the process returns to step 206 to control the phase synchronization unit 40 to attempt channel connection again. However, when the channel connection attempt is established, when the channel between the portable device and the fixed device is connected, the process proceeds to step 210 through step 208 to control the voice amplifier 60 to transmit a dial tone provided from the fixed device. Control to be output through 70.

As described above, the present invention allows the call waiting state to be set by using a predetermined button on the call waiting unit or the dial unit, so that the call waiting state can be controlled without separately providing a call waiting unit on the portable device. There is an advantage that can be miniaturized. In addition, by enabling the setting of the call waiting state by the operation of the dial unit, there is an advantage that the operation is easier than the operation of the existing call waiting unit. This has a possible advantage.
