Hereinafter, with reference to the drawings in accordance with an embodiment of the present invention.

Referring to FIG. 2, the configuration of a device according to an embodiment of the present invention, the control unit 11 controls the overall operation of the portable device. It also has a ROM for storing program data therein and a RAM for temporarily storing data generated during program execution. The key input unit 12 includes a plurality of keys including a call key for requesting line connection for a call, and provides the control unit 11 with key data generated according to the key operation. The display lamp 13 is a lamp displaying a call state through a telephone line under the control of the control unit 11. The duplexer 15 is connected to the antenna and separates the RF signal transmitted and received by the antenna. The transmitter 14 converts the control data output from the control unit 11 and the audio signal generated from the microphone MIC into modulation and RF signals, and outputs them to the duplexer 15. The receiver 16 frequency converts and demodulates the received RF signal output from the duplexer 15. The audio signal output from the receiver 16 is output to the speaker SPK, and the control data is output to the controller 11. The frequency synthesizer 17 generates a transmit and receive channel frequency for designating a channel of the transmitter 14 and the receiver 16 under the control of the controller 11.

Referring to FIG. 3, a control flow of a caller according to an embodiment of the present invention is provided. The process of searching for a channel and transmitting control data through a selected empty channel, and receiving confirmation data in response to the control data, is described below. The call mode is performed.

Referring to Fig. 4, the control flow of the reception side according to an embodiment of the present invention is to search for a channel in which control data having the same identification code (ID) is received, and to the control data having the same identification code. If the recorded call number is the same as the recorded call number, the process of transmitting confirmation data and performing the call mode, and if the call number recorded in the control data having the same identification code is not the same as the recorded call number, The lamp is turned on in use until the end data is received.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

The call side described below refers to a fixed device or a portable device for transmitting a call or control data, and the receiving side refers to a fixed device or a portable device for performing an operation according to the received control data.

First, referring to FIG. 3, the operation of the caller will be described. In operation 30, the controller 11 sequentially searches for a plurality of channels in order to scour the empty channels by an external request. The channel search generates a channel frequency for selecting a channel by controlling the frequency synthesizer 17 and searches for a channel selected by the channel frequency. If the empty channel is scoured in step 32 by the channel search, the control unit 11 proceeds to step 34. The control unit 11 transmits the control data including the call number of the receiving party to connect the call and the identification code of the wireless telephone in step 34. The control data is configured by the controller 11, and the configured control data is mixed with the channel frequency by the transmitter 14 and transmitted through the duplexer 15. After the control data is transmitted, the control unit 11 proceeds to step 36 and detects receipt of the confirmation data transmitted from the reception side in response to the control data. The reception of the confirmation data is sensed by being received by the receiver 16 through the duplexer 15 in the channel caesared in step 32. If the reception of the confirmation data is detected in step 36, the controller 11 proceeds to step 38 to perform a call with the reception side. If the end of the call is detected in step 40, the controller 11 proceeds to step 42 and transmits end data, which is a control data indicating the end of use. Since the transmission of the termination data is performed in the same manner as the transmission of the control data in step 34, detailed description thereof will be omitted. When the completion data transmission is completed in step 42, the controller 11 proceeds to step 44 to switch to the standby state.

Next, the operation of the reception side will be described with reference to FIG. 4 under the assumption that the configuration is the same. In step 50, the control unit 11 performs a procedure for caesuring a channel for receiving control data having the same identification code according to one radiotelephone. Search multiple channels sequentially. The channel search generates a channel frequency for selecting a channel by controlling the frequency synthesizer 17 and searches for a channel selected by the channel frequency. If the reception of the control data having the same identification code is detected in step 52, the controller 11 proceeds to step 54. The control unit 11 analyzes the control data received in step 54 and determines whether the same call number as its own call number set therein is recorded. If the same call number is recorded in step 54, the control unit 11 determines that the calling party has called itself and transmits confirmation data in step 56. The confirmation data having the identification code of the radio telephone and the call number of the calling party is configured by the control unit 11, and the configured confirmation data is mixed with the channel frequency in the transmission unit 14 and transmitted through the duplexer 15. do. After the confirmation data is transmitted, the controller 11 proceeds to step 58 to perform a call with the caller. However, if it is not the call number in step 54, the control unit 11 determines that the display device 13 in step 60 determines that the fixed device 2 or another portable device 4, 6, 8 has requested a call. Turn on. The display lamp 13 is turned on to indicate that the radiotelephone cannot be used because the fixing device 2 or other portable devices 4, 6 and 8 are in use. After the display lamp 13 is turned on, the controller 11 proceeds to step 62 and detects reception of the end data through the channel selected in steps 50 and 52. The reception of the termination data indicating the end of use is detected by the reception unit 16 through the duplexer 15. When the reception of the end data is detected in step 62, the control unit 11 proceeds to step 64 to turn off the display lamp 13 to notify that the use is finished so as to use the apparatus of the reception side.

The present invention has the effect of improving the convenience of the user by trying to make a call in the released state by telling that the fixed device or other portable device is in use.
