Patent number: 7848752Abstract: Disclosed is a handoff processing method capable of restarting fast communications. The handoff processing method stores in a handoff buffer Host Control Interface (HCI) data and transmission data upon communications in a state where an Access Point is interlinked with an external device. Further, the method forwards the HCI data and the transmission data buffered in the handoff buffer to a new Access Point (AP) transmitting a message indicating setup completion of a connection if the message indicating setup completion of a connection with the external device is transmitted from the new AP after a handoff occurs as the external device moves. Accordingly, throughputs are not lowered despite handoff occurrences in poor wireless channel environments, so that service quality can be enhanced.Type: GrantFiled: December 31, 2003Date of Patent: December 7, 2010Assignee: Samsung Electronics Co., Ltd.Inventors: Yong-suk Kim, Won-yong Yoon, Kyun-hyon Tchah, Doo-seop Eom, Won-hee Lee, Tae-jin Lee, Yang-ick Joo

Patent number: 7768991Abstract: A method and system for determining a state of a first node in a wireless network consisting of a plurality of nodes. The first node determines one of at least two power sensitivity levels by considering at least one of an available power and a standby packet. The first node determines whether it remains in active state or inactive state by considering a power sensitivity level transmitted from at least one second node which corresponds to the first node and the determined power sensitivity level. Also, the corresponding node has an identical state to the first node, so that unnecessary power consumption can be prevented.Type: GrantFiled: April 28, 2005Date of Patent: August 3, 2010Assignee: Samsung Electronics Co., Ltd.Inventors: Yong-suk Kim, Won-yong Yoon
