Hereinafter, an embodiment of the present invention will be described in detail based on the above-described configuration.

제2도에서 제1,2송수신 모듈(TR1, TR2)은 각각, fR1, fT1과 fR2, fT2의 반송파 주파수를 송수신한다.In FIG. 2, the first and second transmit / receive modules TR1 and TR2 transmit and receive carrier frequencies of fR1, fT1, fR2, and fT2, respectively.

다수의 휴대장치(HS1-HSn)중 일례로 제1휴대장치(HS1)를 사용하여 고정장치와 통신하여 국선통화를 할거나, 고정장치와 일례로 제1휴대장치(HS1)간의 내선통화를 할 때에는, 상기 제1휴대장치(HS1)와 상기 고정장치의 제1송수모듈(TR1)이 상호 통신하게 된다.One of the mobile devices HS1-HSn uses the first mobile device HS1 to communicate with the fixed device to make a trunk line call, or when making an internal call between the fixed device and the first mobile device HS1. The first portable device HS1 and the first transport module TR1 of the fixed device communicate with each other.

이때 상기 제1송수모듈(TR1)이 반송파 주파수는 제어부(CT)의 제1제어신호에 의해 제1휴대장치의 반송파 주파수와 일치하게 되며, 만일 제n휴대장치(HSn)와 고정장치가 통신하게 되면 상기 제1송수모듈(TR1)의 반송파 주파수는 역시 상기 제어부(CT)의 제1제어신호에 의해 상기 제n휴대장치(HSn)의 반송파 주파수와 일치된다.In this case, the carrier frequency of the first transport module TR1 matches the carrier frequency of the first mobile device by the first control signal of the controller CT, and if the nth mobile device HSn communicates with the fixed device, When the carrier frequency of the first transport module TR1 is equal to the carrier frequency of the n-th mobile device HSn by the first control signal of the controller CT.

휴대장치기간(HS1-HSn)의 상호통신시에는, 일례로 제1휴대장치(HS1)와 제n휴대장치(HSn)간의 상호통신시에는, 먼저 제1송수신모듈(TR1)이 제1휴대장치(HS1)의 송신주파수(fT1)에 일치하여 제1휴대장치(HS1)의 송신신호를 수신한다. 이후 제1송신 모듈은 상기 수신된 신호를 복조부(12)에서 복조하고, 복조된 신호를 송신측 오디오부(13)를 통하여 제1스위칭수단(SW2)으로 출력한다. 제1스위칭수단(SW1)은 제어부(CT)의 제3제어신호를 수신하며, 상기 제3제어신호에 스위칭제어되어 상기 제1스위칭모듈(TR1)의 송신측 오디오부(13)으로부터 수신된 신호를 제2송신모듈(TR2)의 송신측 오디오부(24)로 출력한다.In the intercommunication of the portable device period HS1-HSn, for example, in the intercommunication between the first portable device HS1 and the n-th portable device HSn, firstly, the first transmission / reception module TR1 is the first portable device. The transmission signal of the first mobile device HS1 is received in accordance with the transmission frequency fT1 of the HS1. Thereafter, the first transmitting module demodulates the received signal in the demodulator 12 and outputs the demodulated signal to the first switching means SW2 through the transmitting audio unit 13. The first switching means SW1 receives a third control signal of the control unit CT, and is controlled by switching to the third control signal and received from the transmitting side audio unit 13 of the first switching module TR1. Is output to the transmitting side audio section 24 of the second transmission module TR2.

제2송수신모듈(TR2)은 상기 제어부(CT)의 제2제어신호에 제어되어 상기 오디오부(24)를 통해 수신된 신호를 송신측 변조부(25)에서 변조하여 RF송신부(26)를 거쳐 제n휴대장치(HSn)로 전송한다. 이때 상기 제1송수모듈(TR1)의 복조부(12)와 상기 제2송수신모듈(TR2)의 변조부(25)와의 복,변조상태는 상기 제어부(CT)의 제1,2제어신호에 의해 제어되어 상기 제1,n휴대장치(HS1,HSn)의 반송파 주파수에 일치된다. 또 상기 제n휴대장치(HSn)의 송신신호는 제2송수신모듈(TR2)의 수신측 복조부(22)에서 복조된후, 오디오부(23) 및 제2스위칭부(SW2)를 거쳐 제1송수모듈(TR1)의 송신측 오디오부(14)에 입력된다.The second transmission / reception module TR2 is controlled by the second control signal of the control unit CT to modulate the signal received through the audio unit 24 in the transmission-side modulation unit 25 to pass through the RF transmission unit 26. Transmit to the nth mobile device (HSn). In this case, the demodulation and modulation states of the demodulation unit 12 of the first transmission module TR1 and the modulation unit 25 of the second transmission / reception module TR2 are controlled by the first and second control signals of the control unit CT. It is controlled to match the carrier frequency of the first and n portable devices HS1 and HSn. In addition, the transmission signal of the n-th portable device HSn is demodulated by the receiving side demodulator 22 of the second transmission / reception module TR2, and then passes through the audio unit 23 and the second switching unit SW2. It is input to the transmission side audio part 14 of the water transmission module TR1.

그리고 상기 제1송수모듈(TR1)은 이를 변조부(15)에서 변조한 후 RF송신부(16)를 통해 상기 제1휴대장치(HS1)로 송신한다. 이때 고정장치내의 각부 동작은 상기 제어부(CT)의 제1,2,3제어신호에 의해 수행되며 이로서 상기 제1휴대장치(HS1)와 제n휴대장치(HSn)간에 통화로가 형성되어 통화가 가능해진다.The first transmitter module TR1 modulates the modulator 15 by the modulator 15 and transmits the modulated module 15 to the first portable device HS1 through the RF transmitter 16. At this time, the operation of each part in the fixed device is performed by the first, second, and third control signals of the control unit CT, whereby a communication path is formed between the first mobile device HS1 and the nth mobile device HSn. It becomes possible.

상술한 바와 같이 본 발명은 휴대장치끼리의 통화가 가능하게 하여 복수의 휴대장치의 효율을 증가시킬 수 있는 잇점이 있다.As described above, the present invention has an advantage of enabling communication between portable devices to increase efficiency of a plurality of portable devices.
