Abstract
Provided are a method and a device for processing network slice selection assistance information (NSSAI) rejected due to a network slice-specific authentication and authorization (NSSAA) failure. A user equipment (UE) receives a UE configuration update command message from an access and mobility management function (AMF). On the basis of failure of NSSAA with respect to single NSSAI (S-NSSAI0, the UE configuration update command message includes time information related to a timer. The UE adds the S-NSSAI to a rejected NSSAI, starts the timer on the basis of the time information, and deletes the S-NSSAI included in the rejected NSSAI after the timer expires.
