Title: (KO) 와이파이 P2P 디바이스(Wi-Fi Peer to Peer Device)의 디스커버리(Discovery) 방법 및 장치
(EN) PEER TO PEER DEVICE DISCOVERY METHOD AND DEVICE THEREOF CAPABLE OF INCREASING PEER TO PEER CONNECTION SPEED BETWEEN DEVICES
Abstract: front page image
(KO) 본 발명은 와이파이 P2P 디바이스의 디스커버리 방법 및 장치에 관한 것이다. 본 발명의 실시예에 따른 와이파이 P2P 디바이스(Wi-Fi P2P Device)의 디바이스 디스커버리(Device Discovery) 방법은 수정 P2P 디바이스 디스커버리(Modified P2P Device Discovery)의 실행 명령이 입력되는 단계; 상기 와이파이 P2P 디바이스가 자체적으로 그룹 오너(Group Owner)로 설정하는 단계; 프로브 요청(probe request)에 응답할 수 있는 그룹 오너 수신 모드(Group Owner Receive mode)에 진입하는 단계; 및 프로브 요청을 송신하는 외부 디바이스를 디스커버리 하는 단계를 포함하는 것을 특징으로 한다.
(EN) PURPOSE: A P2P(Peer to Peer) device discovery method and device thereof are provided to offer connection request attempt environment by enabling a legacy device to confirm the existence of a Wi-Fi(Wireless Fidelity) P2P device. CONSTITUTION: A discovery mode establishment unit(131) establishes a discovery mode as a modified P2P device discovery unit. A group owner establishment unit(132) autonomously establishes a P2P device as a group owner. An operating unit(133) enters into a group owner reception mode. The operating unit discovers an external device. The external device transmits a probe request. COPYRIGHT KIPO 2012
