Description
Claims (4)
- 무선 랜에서의 멀티미디어 데이터 전송 방법에 있어서,무선 LAN에서 전송할 패킷의 우선 순위를 동영상, 음성, 데이터의 순으로 미리 정하고 우선 순위가 높은 패킷 순으로 백오프 타임을 짧게 설정하는 과정과;상기 무선 LAN에서 데이터 패킷의 전송 중에 우선 순위가 높은 패킷이 입력되는 경우에 상기 데이터 패킷의 전송을 중지시키고 대신에 우선 순위가 높은 패킷에게 전송 매체를 선점시키는 과정과;상기 전송 중지된 데이터 패킷을 별도로 저장함과 동시에 상기 우선 순위가 높은 패킷을 전송 매체를 통해 전송하는 과정과;상기 우선 순위가 높은 패킷을 모두 전송한 후에 상기 저장된 데이터 패킷을 판독해 전송하는 과정을 포함하는 것을 특징으로 하는 무선 랜에서의 멀티미디어 데이터 전송 방법.
- 삭제
- 제 1항에 있어서, 상기 전송 중지된 데이터 패킷은 보류 데이터 관리 버퍼에 저장되는 것을 특징으로 하는 무선 랜에서의 멀티미디어 데이터 전송 방법.
- 제 1항에 있어서, 상기 저장된 데이터 패킷을 판독해 전송하는 과정은,상기 저장된 데이터 패킷의 백오프 타임을 전송 대기중인 데이터 패킷의 백오프 타임 보다 짧게 설정하는 단계와;상기 우선 순위가 높은 패킷을 모두 전송한 경우에 상기 전송 대기중인 데이터 패킷 대신에 상기 저장된 데이터 패킷을 먼저 전송하는 단계와;상기 저장된 데이터 패킷을 전송한 후에 상기 전송 대기중인 데이터 패킷을 전송하는 단계를 포함하는 것을 특징으로 하는 무선 랜에서의 멀티미디어 데이터 전송 방법.
