데이타 버퍼링을 이용한 데이타 전송방법Data transfer method using data buffering

본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음Since this is an open matter, no full text was included.

제 3 도는 본 발명을 수행하기 위한 시스템도, 제 4 도는 본 발명의 흐름도, 제 50 도는 제 4 도의 각 모듈의 흐름도.3 is a system diagram for carrying out the present invention, FIG. 4 is a flowchart of the present invention, and FIG. 50 is a flowchart of each module of FIG.

Claims (1)

데이타 통신의 흐름을 제어하는 중앙처리장치(10)와, 프로그램을 저장하고 있는 롬(20)과, 데이타를 일시 저장하는 램(30)과, 듀얼 입출력 포트로 구성되어 A포트는 각각 상이한 전송속도를 갖는 제1 및 제 2 데이타 단말에 접속하고, B포트는 교환기의 스위칭회로에 접속하여 데이타의 입출력을 제어하는 제1 및 제 2 입출력장치(40,50)를 구비한 데이타 통신 서비스 시스템에 있어서, 발신측 데이타 단말에서 데이타 출력시 데이타를 리드하여 절단 요구 분석용으로 상기 램에 저장하는 동시에 상기 스위칭회로로 전송하는 제 1 과정과, 상기 제 1 과정 수행후 상기 스위칭회로를 통해 데이타 입력시 착신측 데이타 단말의 전송속도에 맞도록 입력데이타를 버퍼링하는 제 2 과정과, 상기 제 2 과정 수행후 상기 버퍼링 데이타 유무를 검사하여 버퍼링데이타를 착신측 데이타 단말로 전송하는 제 3 과정과, 상기 제 1,2,3과정을 수행하지 않을시 상기 램의 저장 데이타중 요구 데이타 수신 유무를 검사하여 이에따라 통신로를 제어하는 제 4 과정으로 이루어짐을 특징으로 하는 데이타 버퍼링을 이용한 데이타 전송방법.The central processing unit (10) for controlling the flow of data communication, the ROM (20) for storing programs, the RAM (30) for temporarily storing data, and dual input / output ports are configured to have different transmission speeds. In a data communication service system having first and second input / output devices (40, 50) for connecting to first and second data terminals having a second terminal, and a port B connected to a switching circuit of an exchange to control input and output of data. A first step of reading data from the calling data terminal and storing the data in the RAM for cutting request analysis and simultaneously transmitting the data to the switching circuit; and receiving data when the data is input through the switching circuit after performing the first step. A second process of buffering the input data to match the transmission speed of the side data terminal, and checking the presence of the buffered data after performing the second process to attach buffering data; A third process of transmitting to the side data terminal, and a fourth process of checking whether or not the request data is received from the stored data of the RAM when the first, second, and third processes are not performed, and controlling the communication path accordingly. A data transfer method using data buffering. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
