Title:
RADIO ACCESS NETWORK NODE, WIRELESS TERMINAL, CORE NETWORK NODE, AND METHODS FOR THESE
Document Type and Number:
WIPO Patent Application WO/2018/029930
Kind Code:
A1
Abstract:
During handover of a wireless terminal (1) from a first network to a second network, a target RAN node (3): receives slice information relating to network slices inside the second network to which the wireless terminal (1) is connected, from a core network (5); responds to reception of the slice information and generates wireless resource settings information used by the wireless terminal (1) in the second network after handover; and sends the wireless resource settings information to the wireless terminal (1) via the first network. As a result, the present invention can contribute to making appropriate AS layer settings or NAS settings for a target RAT during handover between RATs.
