Abstract:
Systems, methods, apparatuses, and computer program products for user equipment (UE) context duplication. In certain embodiments, when a UE may resume at a target network node within its configured radio area, a duplication of a UE context may occur at the target network node, and the target network node may allocate an additional/secondary identifier to the UE. The secondary identifier may indicate the UE's identity within the network. When configured with a secondary identifier, the UE may retain an original/primary identifier assigned by the anchor network node. The anchor network node may retain the UE context and may maintain user plane connectivity to a core network. The UE may use this primary identifier for operations within the configured radio area, whereas the secondary identifier may be used when resuming operations to a cell that is outside of the configured radio area.
