METHOD AND APPARATUS FOR CONTROLLING DISCONTINUOUS RECEPTION AT MOBILE COMMUNICATION SYSTEM

摘要

PURPOSE: A device and a method for controlling discontinuous reception in a mobile communication system are provided to determine a valid DRX(Discontinuous Reception) timing in a resource system of long and short DRX operation, thereby embodying a normal operation of a terminal. CONSTITUTION: An MS(Mobile Station) receives DRX(Discontinuous Reception) operation parameter from a BS(Base Station). Is a current DRX operation setting is set to a short DRX cycle from the parameter, the terminal set a sub frame as a on-duration start time. The sub frame satisfies a condition of [(SFN * 10)+subframe number] modulo (Short DRX Cycle)=(DRX Start Offset) modulo (Short DRX Cycle).
