Title:
NETWORK SLICE SELECTION FOR INACTIVE STATE AND REESTABLISHMENT
Document Type and Number:
WIPO Patent Application WO/2022/206448
Kind Code:
A1
Abstract:
Aspects of the disclosure relate to user equipment (UE) behavior for intended network slice selection in the radio resource control (RRC) inactive state or for RRC reestablishment. The intended network slice includes one or more single-network slice selection assistance information (S-NSSAIs) utilized by the UE in a particular use case. Examples of use cases include cell reselection in the RRC inactive state, RRC reestablishment, or selection of a random access channel (RACH) resource and/or a RACH parameter to perform an RRC resume procedure in the RRC inactive state. Aspects further relate to UE behavior for selection of a RACH resource to perform a random access procedure when no network slice information is indicated.
