1. A method performed by an access and mobility management function (AMF) in a wireless communication system, the method comprising:
transmitting, to a network slice admission control function (NSACF), a request message for a slice availability check including information regarding an access type of a user equipment (UE), based on a registration request of the UE for one or more single network slice selection assistance informations (S-NSSAIs);
in response to the slice availability check being performed for the one or more S-NSSAIs, based on the access type of the UE at the NSACF, receiving a response message including information regarding a result of the slice availability check, from the NSACF; and
transmitting a registration response for the one or more S-NSSAIs to the UE, based on the result of the slice availability check,
wherein the slice availability check includes updating a number of UEs registered for the one or more S-NSSAIs, and
wherein, in case that the UE is already counted for the one or more S-NSSAIs, the number of UEs registered for the one or more S-NSSAIs is not increased.
