A method performed by a base station in a mobile communication system, the method comprising: receiving, from a multi-cell/multicast coordination entity, MCE,, an M2 session start request message for starting a multicast broadcast multicast service, MBMS, session; receiving, from the MCE, an M2 MBMS scheduling information message including information on allocation of resources to the MBMS session in a multicast-broadcast single frequency network, MBSFN, area and discontinuous reception, DRX, parameter values, the DRX parameter values including a DRX inactivity timer, a short duration timer, a long duration timer, and a short DRX cycle timer for an MBMS; transmitting, to a plurality of terminals, a radio resource control, RRC, MBSFN area configuration message of a multicast control channel, MCCH, the RRC MBSFN area configuration message including the DRX parameter values included in the M2 MBMS scheduling information message and a DRX indicator value indicating whether a DRX mode is applied; wherein the DRX inactivity timer indicates a number of multicast scheduling information, MSI, counts in which data is not transmitted and which becomes a reference when a terminal of the plurality of terminals is transitioned from normal operation to a short DRX mode; the short DRX cycle timer indicates a number of reception cycle counts in which data is not transmitted, and becomes a reference when the terminal of the plurality of terminals is transitioned from the short DRX mode to a long DRX mode; the short duration timer indicates a value that determines the reception cycle in the short DRX cycle of the terminal; the long duration timer indicates a value that determines the reception cycle in the long DRX cycle of the terminal; identifying whether a time for transmitting first data is a reception cycle of the terminals based on the DRX parameter values and the DRX indicator value; storing the first data in a buffer in case of a first time is not a reception cycle of the terminals; and transmitting, to the plurality of terminals, the first data and second data to be transmitted at a second time to the terminal at the second time that is the reception cycle of the terminal that comes after the at least one first time. receiving, from a multi-cell/multicast coordination entity, MCE,, an M2 session start request message for starting a multicast broadcast multicast service, MBMS, session; receiving, from the MCE, an M2 MBMS scheduling information message including information on allocation of resources to the MBMS session in a multicast-broadcast single frequency network, MBSFN, area and discontinuous reception, DRX, parameter values, the DRX parameter values including a DRX inactivity timer, a short duration timer, a long duration timer, and a short DRX cycle timer for an MBMS; transmitting, to a plurality of terminals, a radio resource control, RRC, MBSFN area configuration message of a multicast control channel, MCCH, the RRC MBSFN area configuration message including the DRX parameter values included in the M2 MBMS scheduling information message and a DRX indicator value indicating whether a DRX mode is applied; wherein the DRX inactivity timer indicates a number of multicast scheduling information, MSI, counts in which data is not transmitted and which becomes a reference when a terminal of the plurality of terminals is transitioned from normal operation to a short DRX mode; the short DRX cycle timer indicates a number of reception cycle counts in which data is not transmitted, and becomes a reference when the terminal of the plurality of terminals is transitioned from the short DRX mode to a long DRX mode; the short duration timer indicates a value that determines the reception cycle in the short DRX cycle of the terminal; the long duration timer indicates a value that determines the reception cycle in the long DRX cycle of the terminal; identifying whether a time for transmitting first data is a reception cycle of the terminals based on the DRX parameter values and the DRX indicator value; storing the first data in a buffer in case of a first time is not a reception cycle of the terminals; and transmitting, to the plurality of terminals, the first data and second data to be transmitted at a second time to the terminal at the second time that is the reception cycle of the terminal that comes after the at least one first time.
