1. A method performed by a terminal in a wireless communication system, the method comprising:
attempting an access to the network;
performing an access barring check for an access category corresponding to the access;
in case that the access is barred according to the access barring check, starting a barring timer for the access category corresponding to the access;
in case that information on an access identity corresponding to the access and the access category is received by an access stratum (AS) layer from a non-access stratum (NAS) layer while the barring timer is running, transmitting, to the NAS layer, information indicating that the access corresponding to the access category is barred, wherein in case that the information on the access identity and the access category is not received while the barring timer is running, the information indicating that the access corresponding to the access category is barred is not transmitted to the NAS layer;
in case that a barring of the access corresponding to the access category is alleviated, identifying whether the access corresponding to the access category was informed to the NAS layer as barred; and
in case that the barring of the access corresponding to the access category is alleviated and the access corresponding to the access category was informed to the NAS layer as barred, informing, to the NAS layer, an alleviation of the barring of the access corresponding to the access category, wherein in case that the information indicating that the access corresponding to the access category is barred is not transmitted to the NAS layer, the alleviation of the barring of the access is not informed to the NAS layer.
