Title:
UE, CORE NETWORK NODE, ACCESS NETWORK NODE, AMF DEVICE, TERMINAL, AND METHOD FOR SAME
Document Type and Number:
WIPO Patent Application WO/2022/080244
Kind Code:
A1
Abstract:
This AMF device (2) receives, from the terminal (1), a registration request message including first information indicating a support of a limitation function pertaining to simultaneous uses of network slices. The AMF device (2) receives, from a UDM device (8), terminal subscriber information including second information indicating limitations pertaining to simultaneous uses of network slices. When receiving the first information and the second information, the AMF device (2) transmits, to the terminal (1), a registration approval message including Single Network Slice Selection Assistance Information (S-NSSAI) and third information. The third information is included in the terminal subscriber information, and indicates limitations pertaining to simultaneous uses of network slices pertaining to the S-NSSAI. This can contribute to the implementation of registration management adapted to various limitations pertaining to, for example, the uses of the network slices.
