Title:
WIRELESS ACCESS NETWORK NODE DEVICE, AMF DEVICE, AND METHOD FOR SAME
Document Type and Number:
WIPO Patent Application WO/2021/199581
Kind Code:
A1
Abstract:
A RAN node device (1) sends, to a core network AMF (3), slice support information indicating a network slice that is supported by another RAN node (2) that is capable of being used as a secondary node in dual connectivity in which the RAN node device (1) operates as a master node. This makes it possible, for example, to enable the AMF to determine a network slice for which a UE is granted permission while taking network slices that are supported by a secondary node in dual connectivity into account.
