Abstract
An AMF apparatus () receives, from a terminal (), a registration request message including first information indicating support for a restriction feature related to simultaneous use of network slices. The AMF apparatus receives, from a UDM apparatus (), terminal subscription information including second information that indicates a restriction related to simultaneous use of network slices. Upon receiving the first information and the second information, the AMF apparatus () sends, to the terminal (), a registration accept message including a Single Network Slice Selection Assistance Information (S-NSSAI) and third information. The third information is included in the terminal subscription information and indicates for the S-NSSAI a restriction related to simultaneous use of network slices. This can contribute, for example, to achieving registration management adapted to various restrictions on the use of network slices.
