PDU Session Handover

Abstract:

Apparatuses, systems, and methods for PDU session handover between cellular and non-cellular access technologies. The UE may determine to transfer one or more on-going PDU sessions from a first RAN to a second RAN based on detection of a mobility condition. The UE may transmit an allowed PDU session status IE to an AMF. The allowed PDU session IE may be transmitted via a registration request when the first RAN supports 3GPP access and the second RAN supports non-3GPP access. The allowed PDU session status IE may be transmitted via service request when the first RAN supports non-3GPP access and the second RAN supports 3GPP access. The allowed PDU session IE may trigger establishment of user plane resources for the one or more on-going PDU sessions via a UPF.
