Datapath architecture for improved mobility

Abstract

This disclosure relates to techniques for establishing a data path with improved mobility features in a wireless communication system. A wireless device may establish a wireless link with an air-interface node of a cellular network. Cell-specific physical layer security coding may be performed for the wireless link between the wireless device and the air-interface node. User-plane termination may be established between the wireless device and a controller entity of the cellular network, which may be a cloud-deployed network function, via the wireless link. The wireless device may form user-plane uplink packets for the controller entity, and apply end-to-end security to generate encrypted user-plane uplink packets at a user-plane termination layer of the wireless device. The encrypted user-plane uplink packets may be provided to the controller entity via the wireless link with the air-interface node.
