Abstract
Embodiments of a method performed by a radio access node for network scheduled User Equipment (UE) transition to connected mode and corresponding embodiments of a radio access node are disclosed. In some embodiments, a method performed by a radio access node comprises receiving: (a) a notification request from an Access and Mobility Management Function (AMF) to retrieve reachability information for a UE or (b) downlink data to be communicated to the UE. The method further comprises, upon receiving either (a) or (b), determining that the UE is in an inactive state and is currently unreachable. The method further comprises sending information to the AMF that notifies the AMF that the UE is currently unreachable. The information comprises information that indicates that RAN paging of the UE is scheduled or scheduling assistance information. Embodiments of method performed by an AMF and corresponding embodiments of an AMF are also disclosed.
