Abstract: The disclosure pertains to a method implemented in a Wireless Transmit/Receive Unit (WTRU) for service continuity during an application context relocation (ACR) procedure. The method includes determining, by the WTRU, one or more local area data network (LADN) data network names (DNNs) that require service continuity. The method additionally includes indicating, to a network by the WTRU, the LADN DNNs that require service continuity. The network is configured to use the list to maintain a protocol data unit (PDU) session toward a source LADN DNN, after the WTRU leaves a service area of a source LADN, while ACR is being executed and release the PDU session when the ACR is complete.

Abstract: Disclosed procedures, methods, architectures, apparatuses, systems, devices, and computer program products address limitations of conventional single-PDB (or more generally, single set of QoS requirements) approach in providing QoS. Disclosed solutions employ two or more QoS related parameter values and associated criteria for their selection, enabling more efficient data transmission and reception between a UE and the core network. The procedure can be initiated by either the network or the UE, utilizing various values as triggers for managing and adjusting current data traffic. For example, a RAN node can use criteria information such as the amount of buffered video on the UE to determine when to switch the 5QI value of a QoS Flow from a first value to a second value.
