Abstract
Network slice information management by a UEhas not been defined for a network slice for which network slice-specific authentication and authorization are pending. A UE may receive, from a core network node, first information indicating that a procedure of network slice-specific authentication and authorization is pending; store first network slice information including one or more pieces of first slice information or one or more pieces of second slice information, the first slice information indicating a slice that a network rejects to be used, the second slice information indicating a slice that the network permits to be used; and store, independently from the first network slice information, second network slice information corresponding to the first information.
