Abstract: Disclosed herein are systems, methods, and computer-readable media for reporting QoE of a UE, as measured and determined from the perspective of the UE to one or more core components of the cellular network to which the UE is attached. The QoE may then be used by the one or more core components for managing and adjusting, if necessary, the cellular services provided to the UE. In one aspect, a method includes determining, at a user device, a quality of experience (QoE) of user device connected to a cellular network and transmitting, via a non-access stratum (NAS) signaling, a value of the QoE from the user device to a core network element of the cellular network, wherein the core network element utilizes the QoE value to manage network access and a quality of service (QoS) of the user device.

Abstract: Systems, methods, and computer-readable media are disclosed for dynamically onboarding a UE between private 5G networks. In one aspect, a private 5G (P5G) federation system can receive a request from a user device for registration with a serving private 5G network, which is part of a P5G federation system. The P5G federation system can further determine that the user device is authenticated with a home private 5G network of the user device, which is also part of the P5G federation system. The P5G federation system can transmit, to the serving private 5G network, a security profile of the user device that is received from the home private 5G network. As follows, the P5G federation system can facilitate onboarding of the user device to the serving private 5G network with the security profile.

Abstract: First, an authentication module may receive an identification (ID) linking request, create a secured ID linking request from the ID linking request, and send the secured ID linking request to a packet gateway module located in a packet core of a mobile network. Next, the packet gateway module may insert into the secured ID linking request, an encrypted version of a mobile identifier corresponding to a client device from which the secured ID linking request was received. Next, a mobile video session manager module may receive from the packet gateway module, the secured ID linking request and link a subscriber of a managed video service corresponding to a video identifier to the client device corresponding to the mobile identifier. A policy corresponding to the subscriber of the managed video service may then be applied to flows over the packet core to and from the client device.
