  • Patent number: 9065616
    Abstract: 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.

  • Patent number: 8446880
    Abstract: A method of performing cell re-selection in a wireless communication system considering mobility of a user equipment comprises detecting cells having signal strength greater than a certain level for a first time interval and a second time interval, determining mobility of the user equipment using at least one of a change level in the number of cells detected for the first time interval and the second time interval and information related to variation of a signal characteristics value of at least one cell commonly detected for the first time interval and the second time interval, and performing cell re-selection considering mobility of the user equipment.

  • Patent number: 8331256
    Abstract: A method includes receiving priority information on priority for different frequency or a Radio Access Technology (RAT), measuring a serving cell periodically, measuring different frequency or RAT with higher priority than the serving cell, and suspending the measurement of different frequency or RAT with the higher priority during a certain time period when a measurement result of the different frequency or RAT with higher priority is lower than a reference value.

  • Patent number: 8320918
    Abstract: 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.

  • Patent number: 8280377
    Abstract: A method of performing cell reselection includes receiving priority for a different frequency or RAT (Radio Access Technology) and information on a validity timer for the priority, starting the validity timer, performing cell reselection based on the priority while the validity timer is running, receiving reconfiguration information of the validity timer, and reconfiguring the validity timer based on the reconfiguration information.

  • Patent number: 8121602
    Abstract: A cell reselection method in a wireless communication system is described. A method of performing cell reselection based on priorities by a user equipment (UE) in a wireless communication system includes selecting one or more candidate cells satisfying a first criterion associated with priorities among a serving cell and neighbor cells, and camping on a cell satisfying a second criterion for cell reselection among the one or more candidate cells.
