1. A method of a user equipment (UE), the method comprising:
transmitting, by the UE to a network entity, a registration request message including a registration type information;
receiving, by the UE from the network entity, a registration accept message including a pending network slice selection assistant information (NSSAI) and a registration result information with an indicator associated with a network slice-specific authentication and authorization (NSSAA) to be performed;
identifying, by the UE, that a previously received allowed NSSAI is invalid based on the registration accept message; and
initiating, by the UE, a service request procedure:
in case that the UE in an idle mode obtains an indication that an access stratum connection is established between the UE and the network entity, or
in case that the UE in a connected mode obtains a fallback indication and the UE has a pending procedure.
