Abstract: PURPOSE: An apparatus and method for protecting privacy in a contents sharing system are provided for users to share contents in network without invasion of privacy. CONSTITUTION: A central control device provides a contents list to users (201), and receives the request of downloading the contents from user devices (203). The central control device determines whether or not the required contents are complete sharing (205). If a range of sharing the contents is limited, the central control device determines whether or not the range covers user ID of a used device (207). If the range does not cover the user ID, the central control device performs a warning procedure (209). If the range covers the user ID, the central control device determines whether the range covers the range of sharing download folders (211). If the range covers the range of sharing download folders, the central control device performs a process of downloading the contents (213). [Reference numerals] (201) Provide a content list; (203) Receive the request of downloading the contents; (205) Are the required contents completely shared?; (207) Does the content sharing range cover the user ID of a device used for log-in?; (209) Perform a warning procedure; (211) Does the sharing range cover the range of sharing download folders?; (213) Perform a process of downloading the contents; (AA) Start; (BB,EE,GG) Yes; (CC,DD,FF) No; (HH) End

Abstract: 본발명은실시간트래픽을위한적응적폴링방법에관한것으로, 동적서비스추가(DSA)를이용하여 BS와 MS가특정서비스를연결시, 혹은동적서비스변경(DSC)을이용하여특정서비스를진행중에초기폴링주기(Tpi)와적응적폴링주기(Tpa)를미리설정한후, 두개의폴링시간간격을하나의주기로볼 경우, 이전주기에새로운패킷이생성되면다음폴링시점을초기폴링주기(Tpi) 시간뒤에할당하고, 이전주기에새로운패킷이생성되지않았으면다음폴링시점을적응적폴링주기(Tpa) 시간뒤에할당함으로써, 트래픽의새로운패킷생성시간사이의상호관계(correlation)를조절할수 있어폴링지연혹은폴링오버를줄일수 있어실시간트래픽서비스를효과적으로수용할수 있다. 또한, 본발명은기존의 rtPS 방식과비교시서비스진행중 BS와 MS 사이의추가적인제어신호가필요하지않으며, Tpi와 Tpa 값의적절한선택에의해온라인게임과같은비주기적인실시간트래픽과영상전화와 VOD 등과같은주기적인실시간트래픽을효과적으로모두수용할수 있다.

Abstract: 복수의 섹터(sector)를 각각 커버(cover)하는 복수의 액세스 포인트(access point, AP) 및 복수의 섹터 내에 존재하는 단말기 간의 시분할 이중화(time division duplexing, TDD) 방식 무선 통신 방법이다. 나아가 이 방법은 하향링크 데이터를 IEEE 802.11 표준에 의한 프레임(frame) 형태로 구성하되, 프레임의 Duration/ID 필드에는 하향링크 전송시간에서 하향링크 전송구간의 시작 시점으로부터 프레임의 전송 시작 시점까지의 경과시간을 뺀 결과인 잔여시간을 입력한다. 위와 같은 방법을 이용하면, 액세스 포인트가 동일한 주파수로 동작하는 섹터 안테나를 사용하는 경우 일종의 히든 노드 문제(hidden node problem)로 인하여 발생하는 성능 저하를 줄일 수 있고, 경쟁방식의 채널 액세스 정책을 채택한 IEEE 802.11 표준 하에서도 단말기의 수정 없이 히든 노드의 영향을 완화시킬 수 있다.
