Hybrid wired and wireless communication device and a wired and wireless communication method thereof
Patent number: 7634273Abstract: A hybrid wired and wireless communication device and a wired and wireless communication method thereof. The wired and wireless communication method includes determining whether a wired communication module has been linked to a wired communication network, setting a wireless communication operating mode of a wireless communication module to an infrastructure mode when it is determined that the wired communication module has not been linked to the wired communication network, and setting the wireless communication operating mode to an ad-hoc mode when it is determined that the wired communication module has been linked to the wired communication network. Therefore, the wireless communication operating mode is automatically set according to whether the wired communication network has been linked to the wired communication module, thereby increasing a user's convenience.Type: GrantFiled: March 9, 2004Date of Patent: December 15, 2009Assignee: Samsung Electronics Co., Ltd.Inventors: Jin-hyung Kim, Seung-soo Oak, Jin-tack Lee, Sung-hoon Bae -

Patent number: 7606600Abstract: A method of connecting a mobile terminal and an AP. The mobile terminal has a short-distance wireless communication module and a mobile communication module, and the AP provides a wired/wireless communication interface. The SID and NID of a network with the AP are stored as SID_Bond and NID_Bond at an initial bonding with the AP. It is determined whether a channel established with the AP has been terminated. If the channel is terminated, the SID_Bond and NID_Bond are compared with an SID and NID for the present position. If they are different, the short-distance wireless communication module is transitioned to a low-power mode.Type: GrantFiled: June 1, 2004Date of Patent: October 20, 2009Assignee: Samsung Electronics Co., LtdInventor: Joung-Kyou Park
