- 이동통신 시스템의 알엘피 프레임 데이터 전송에 있어서,상기 이동통신 시스템에 의하여 알엘피 프레임 데이터를 전송할 채널을 할당하여 호설정하고, 상태변수와 교환변수를 설정하며 알엘피 프레임 데이터를 순서대로 전송하는 알엘피 과정과,상기 과정에서 전송되는 알엘피 프레임 데이터가 오류 발생으로 수신측에서 정상 수신되지 않는 경우, 데이터 유실정도를 측정하여 기준값보다 큰지를 판단하는 유실측정과정과,상기 과정에서 기준값보다 큰 값의 데이터 유실로 판단되면, 교환변수를 재협상 설정하고, 수신되지 않은 프레임 데이터의 재전송을 요청하는 재협상과정과,상기 과정의 재전송되는 프레임 데이터 수신을 성공하면 종료하며, 성공하지 못하면 오류메시지를 표시하고, 호접속된 링크를 해제하여 종료하는 재수신과정으로 이루어진 것을 특징으로 하는 무선환경을 고려한 알엘피 프레임 데이터 수신방법.
- 제1 항에 있어서, 상기 알엘피 과정은,상기 이동통신 시스템에 의하여 알엘피 프레임 데이터를 전송하기 위한 채널을 할당하고 호를 설정하는 과정과,상기 과정에 의하여 설정된 호의 상태변수를 초기화하고 데이터 전송률 및 엘2알을 설정하며, 교환변수를 협상 설정하는 과정과,상기 과정에서 설정된 변수에 의하여 순서대로 전송되는 알엘피 프레임 데이터를 수신측에서 수신하고 모든 프레임 데이터가 오류 없이 수신되었는지를 판단하며 모든 프레임 데이터가 오류 없이 수신되면 종료하는 과정으로 이루어진 것을 특징으로 하는 무선환경을 고려한 알엘피 프레임 데이터 수신방법.
- 제1 항에 있어서, 상기 유실측정과정은,상기 알엘피 과정에서 수신한 프레임 데이터에 오류가 발생한 경우는, 비트오류율 측정으로 프레임 데이터의 유실정도를 측정하는 과정과,상기 과정에서 측정된 프레임 데이터 유실정도가 설정된 소정의 기준값 보다 큰지를 판단하는 과정으로 이루어지는 것을 특징으로 하는 무선환경을 고려한 알엘피 프레임 데이터 수신방법.
- 제1 항에 있어서, 상기 재협상과정은,상기 유실측정과정에서 판단하여 수신된 프레임 데이터의 유실정도가 소정 기준값보다 큰 경우는, 이동통신 시스템과 통신하여 재전송 시간, 재전송 횟수, 프레임 단위 데이터 길이의 교환변수를 재협상하여 결정하고 설정하는 과정과,상기 과정의 교환변수를 이용하여 오류 발생 프레임의 데이터를 재전송 요청하는 과정으로 이루어지는 것을 특징으로 하는 무선환경을 고려한 알엘피 프레임 데이터 수신방법.
- 제1 항에 있어서, 상기 재수신과정은,상기 재협상과정에 의하여 재전송 요청된 프레임 데이터를 오류 없이 수신 성공한 것으로 판단하면 종료로 진행하는 과정과,상기 과정에서 판단하여 재수신된 프레임 데이터에 오류가 있는 경우 오류 메시지를 표시하고, 호접속된 링크를 해제하고 종료로 진행하는 과정으로 이루어진 것을 특징으로 하는 무선환경을 고려한 알엘피 프레임 데이터 수신방법.
- 제4 항에 있어서,상기 교환변수 재협상과정에서 무선환경이 나쁜 경우는, 재전송 시간을 길게 조정하고, 재전송 횟수를 줄이며, 프레임 단위에 구성되는 데이터 크기를 줄이는 것을 특징으로 하는 무선환경을 고려한 알엘피 프레임 데이터 수신방법.
- 제1 항에 있어서,상기 기준값은 오류가 발생된 수신 프레임 데이터의 비트 오류율을 측정하여 무선환경 판단 근거를 확보하는 것을 특징으로 하는 무선환경을 고려한 알엘피 프레임 데이터 수신방법.
