Patent number: 9065616Abstract: A method for transmitting and receiving data in a mobile communication system is disclosed. The data transmission method for allowing a transmission end of the mobile communication system to transmit data to at least one reception end via at least one physical channel includes, transmitting a reception indicator, which indicates whether at least one second physical channel is received, via a first physical channel, such that at least one reception end can determine whether the at least one second physical channel is received using the reception indicator, and transmitting data via a third physical channel controlled by the first physical channel. So, a sleeping time for reducing power consumption can be explicitly indicated by the above data communication method, such that power consumption required for transmitting and receiving data can be minimized.Type: GrantFiled: September 11, 2008Date of Patent: June 23, 2015Assignee: LG ELECTRONICS INC.Inventors: Sung Jun Park, Young Dae Lee, Seon Don Lee, Seung June Yi, Sung Duck Chun

Patent number: 8320918Abstract: Disclosed is a method for determining, by a terminal, its mobility and deciding a time to select another cell in a mobile communication system, in which the terminal determines the mobility by using variation information in signal characteristic values of measurable specific cells, thereby appropriately controlling a size of a time restriction (e.g., Treselection) for a cell re-selection and preventing frequent occurrence of cell selection such as a ping-pong situation, thus to reduce an unnecessary service delay due to the cell re-selection and maximize a service quality for a user.Type: GrantFiled: September 27, 2008Date of Patent: November 27, 2012Assignee: LG Electronics Inc.Inventors: Seon-Don Lee, Sung-Duck Chun, Seung-June Yi, Young-Dae Lee, Sung-Jun Park
