Abstract

본 발명은 방송통신의 고속통신방법에 관한 것으로, 종래의 송신국은 다수의 수신국으로인하여 한 프레임송신후 충분한 시간을 기다린 후 다음 데이타를 송신하므로 통신속도가1:1통신에 비해 매우 늦어지며, 데이타 분실여부를 알수 없으므로 중요한 데이타의 분실시 복수할 수단이 없는 문제점이 있었다. 따라서 본 발명은 방송(Broadcast)통신시 다수의 수신국에 우선순위를 부여하여 우선순위가 가장 높은국이 수신데이타에 대한 확인을 송신하여 송신국으로 하여금 다음 데이타를 송신하게 하여 통신속도를 빠르게하도록 하여 고속성확보를 행하고, 데이타 분실시 재송신요구를 가능하게 하여 분실된 데이타의 복구가 가능하여 방송통신시 통신의 신뢰성을 부여하도록 한 효과가 있다.The present invention relates to a high-speed communication method of broadcast communication, and the conventional transmitting station transmits the next data after waiting enough time after transmitting one frame due to a plurality of receiving stations, so that the communication speed becomes very slow compared to 1: 1 communication. There is a problem that there is no means for revenge in case of loss of important data because it is unknown whether data is lost. Therefore, the present invention prioritizes a plurality of receiving stations in broadcast communication so that the highest priority station transmits a confirmation of the received data so that the transmitting station transmits the next data to speed up the communication speed. Therefore, it is possible to secure high speed, to enable retransmission request when data is lost, to recover lost data, and to provide reliability of communication during broadcast communication.

송신국이 다수의 수신국에게 우선순위를 할당한 후 데이타를 전송함과 아울러 타이머를 기동하는 제1단계와, 상기 제1단계에서 전송데이타의 수신여부를 확인하는 제2단계와, 상기 제2단계에서 전송확인신호(ACK)를 수신하면 마지막 데이타인가를 체크하여 마지막일 경우 데이타를 보내고 우선순위를 해제하고 송신을 종료하는 제3단계와, 상기 제2단계에서 전송확인신호(ACK)가 수신되지 않고 재전송 요구가 없으면 종료시간을 체크하여 그 종료시간에 도달하지 않으면 데이타를 재전송하고 전송확인신호(ACK)수신을 기다리는 제3단계와, 상기 제2단계에서 전송확인신호가 수신되지 않고 재전송요구가 있으면 제1회에 한하여 재전송하고 전송확인신호(ACK)수신을 기다리는 제4단계와, 상기 제3단계에서 종료시간에 도달하거나 제4단계에서 동일프레임에 대해 두번이상재전송 요구시 리셋데이타를 송신한 후 다음 데이타송신을 계속 행하도록 하는 제5단계로 이루어짐을 특징으로 하는 방송통신의 고속통신방법.A first step of transmitting data after the transmitting station assigns priority to a plurality of receiving stations and starting a timer; and a second step of confirming whether or not transmission data is received in the first step; In step 3, when the acknowledgment signal ACK is received, the third step of checking whether the data is the last data and if it is the last, sends the data, releases the priority, and terminates the transmission. In the second step, the acknowledgment signal ACK is received. And if there is no retransmission request, check the end time and if the end time is not reached, retransmit the data and wait for reception of the acknowledgment signal (ACK); and in the second step, the retransmission request is not received. If there is a retransmission for the first time and waits for the reception of the acknowledgment signal (ACK), the end time is reached in the third step or the same frame is received in the fourth step. And a fifth step of continuing to transmit the next data after transmitting the reset data two or more times when retransmission is requested. 각각의 수신국들은 먼저 송신국에서 보낸 우선순위에 의해 자국의 우선순위를 결정한 수 데이타수신모드에서 데이타를 기다리는 제1단계와, 상기 제1단계에서 데이타수신모드시 정상데이타를 수니하면 그 데이타를 저장한 후 자국이 최우선순위일 경우 수신확인신호를 송신한 후 다음 데이타를 기다리는 제2단계와, 상기 제1단계에서 데이타수신모드에서 정상데이타가 아니고 재전송요구 데이타인 경우 수신대기상태에서 재전송을 기다리는 제3단계와, 상기 제1단계에서 데이타수신모드에서 정상데이타가 아니고 데이타분실일 경우 1회에 한하여 재전송을 송신국에 요구하고 수신대기상태로 가는 제4단계로 이루어짐을 특징으로 하는 방송통신의 고속통신방법.Each receiving station first waits for data in the receive data receiving mode, which has determined its own priority based on the priority sent from the transmitting station, and receives the normal data in the data receiving mode in the first step. A second step of waiting for the next data after transmitting an acknowledgment signal if the local station is the highest priority after storing, and waiting for retransmission in the reception standby state if the retransmission request data is not normal data in the data reception mode in the first step. And a fourth step of requesting retransmission to the transmitting station only once in case of data loss in the data receiving mode and normal data loss in the first step.
