Title
(EN) PEER TO PEER DEVICE DISCOVERY METHOD AND DEVICE THEREOF CAPABLE OF INCREASING PEER TO PEER CONNECTION SPEED BETWEEN DEVICES
(KO) 와이파이 P2P 디바이스(Wi-Fi Peer to Peer Device)의 디스커버리(Discovery) 방법 및 장치
Abstract
(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
