1. A method performed by an access and mobility management function (AMF) in a wireless communication system supporting an enhanced coverage, the method comprising:
identifying whether or not a restriction on a use of the enhanced coverage is changed for a user equipment (UE);
transmitting, to the UE via a radio access network (RAN), a configuration update command message including first information for informing a change of the restriction in response that the restriction on the use of the enhanced coverage is changed for the UE and second information requesting the UE to perform a registration procedure with the AMF;
receiving, from the UE via the RAN, a registration request message based on the transmission of the configuration update command message including the first information and the second information;
transmitting, to the UE via the RAN, a registration accept message in response to reception of the registration request message;
determining that a non-access stratum (NAS) timer to be applied in a session management function (SMF) shall be updated based on the change of the restriction on the use of the enhanced coverage; and
triggering a protocol data unit (PDU) session modification procedure to the SMF serving the UE, in response to the determination.
