Abstract: Disclosed are a method and a device for controlling access in a wireless communication system and, particularly, to a method and a device for management and access control of a network (NW) slice in a wireless communication system. According to one embodiment of the disclosure, a method by which a first NW function (NF #1) device of a wireless communication system manages an NW slice comprises the steps of: receiving an NW slice selection assist information (NSSAI) availability update message from at least one second network function (NF #2) device included in a NW slice; storing information included in the NSSAI availability update message; transmitting, to the NF #2, a response message to the NSSAI availability update message; and transmitting, to the NF #2, a message that requests changed information when a state or a configuration is changed to the NF #2, wherein the NSSAI availability update message can include the capacity parameters of the NW slice.
