Title:
A METHOD FOR SYNCHRONIZING STATUS OF UE IN A COMMUNICATION NETWORK
Document Type and Number:
WIPO Patent Application WO/2019/221033
Kind Code:
A1
Abstract:
The present disclosure relates to synchronizing a temporary identity in the UE and the network when the UE is RRC Inactive state over 3GPP access and temporary identity of the UE is changed over a Non-3GPP access in a scenario when the UE is connected to the same AMF via 3GPP and non-3GPP access.
