A communication control method performed in a mobile communication system, the method comprising: receiving, by a user equipment in a radio resource control, RRC, connected state, RRC Connection Release message from a base station included in a radio access network, RAN, wherein the RRC Connection Release message includes an indication causing the user equipment to transition from the RRC connected state to a specific state and information indicating a RAN paging area where the RAN performs paging for the user equipment in the specific state, the specific state is a state in which the RRC connection is suspended and a connection established in an interface between the base station and a core network for the user equipment is maintained, and the state is different from the RRC connected state and an RRC idle state; performing, by the user equipment an operation of transitioning from the RRC connected state to the RRC specific state in response to receiving the RRC Connection Release message; transmitting, from the base station to a neighboring base station, a paging request that requests the neighboring base station to perform paging for the user equipment in the specific state, the paging request including identification information of the user equipment and a discontinuous reception, DRX, configuration of the user equipment; performing a cell reselection operation by the user equipment in the specific state; and performing, by the user equipment in the specific state, an operation of transitioning from the specific state to the RRC idle state when a cell not supporting the specific state is reselected in the cell reselection operation. receiving, by a user equipment in a radio resource control, RRC, connected state, RRC Connection Release message from a base station included in a radio access network, RAN, wherein the RRC Connection Release message includes an indication causing the user equipment to transition from the RRC connected state to a specific state and information indicating a RAN paging area where the RAN performs paging for the user equipment in the specific state, the specific state is a state in which the RRC connection is suspended and a connection established in an interface between the base station and a core network for the user equipment is maintained, and the state is different from the RRC connected state and an RRC idle state; performing, by the user equipment an operation of transitioning from the RRC connected state to the RRC specific state in response to receiving the RRC Connection Release message; transmitting, from the base station to a neighboring base station, a paging request that requests the neighboring base station to perform paging for the user equipment in the specific state, the paging request including identification information of the user equipment and a discontinuous reception, DRX, configuration of the user equipment; performing a cell reselection operation by the user equipment in the specific state; and performing, by the user equipment in the specific state, an operation of transitioning from the specific state to the RRC idle state when a cell not supporting the specific state is reselected in the cell reselection operation.
