Abstract: Systems and methods described herein enable user-aware and application-aware dynamic slicing for mobile networks. A network device in a provider network receives a dynamic slice request from a client application. The dynamic slice request includes authorization credentials and a quality of service (QoS) indication for the client application. In response to the dynamic slice request, the network device generates a traffic descriptor value. The traffic descriptor value includes an access token that indicates the QoS authorized for the client application. The network device pushes updated UE Route Selection Policy (URSP) rules to a modem of the UE device, and also separately directs the traffic descriptor value to the client application. The network device receives, from the UE device, a protocol data unit (PDU) session establishment request that includes network slice selection information based on the traffic descriptor value.
