Patent number: 8259618Abstract: In wireless network communication, the present invention provides a method of checking whether information on a request for a mode change is received for a prescribed channel time in a manner that a device configuring a network enters a power save mode in the course of not performing data transmission/reception and that a modem enters an awake state from a sleep state for the prescribed channel time. And, the prescribed channel time is determined to correspond to a time for transmitting a beacon. According to one preferred embodiment of the present invention, a modem of a device in a power save mode enters an awake state for a channel time period for broadcasting a beacon and then checks whether information on a power management mode change is received. If the information does not exist, a sleep state is reentered. If the power management mode change information is received, a power is managed by performing data transmission/reception in a manner of switching to a normal mode.Type: GrantFiled: September 17, 2009Date of Patent: September 4, 2012Assignee: LG Electronics Inc.Inventors: Beom Jin Jeon, Hyeon Cheol Cho, Taek Soo Kim

Patent number: 8238308Abstract: The present invention relates to a handover method that a current coordinator transfers a coordinating function of controlling a network to a different device configuring the network. The present invention relates to a method of selecting an optimal device as a coordinator in selecting the different device using priority information decided by a prescribed evaluation reference. And, the present invention relates to a method of simplifying a procedure in a manner of transmitting relevant information together with a handover request message. In a wireless network including a coordinator, a secondary coordinator is decided in advance. If the coordinator is suddenly unable to perform a function, the present invention relates to a method of enabling the function of the coordinator to be performed by the decided secondary coordinator. Thus, a process for transferring the coordinating function without the handover process is called a recovery process.Type: GrantFiled: August 18, 2010Date of Patent: August 7, 2012Assignee: LG Electronics Inc.Inventors: Beom Jin Jeon, Hyeon Cheol Cho, Taek Soo Kim
