Wireless network slice selection in wireless user equipment (UE)
A wireless access node wirelessly broadcasts System Information Blocks (SIBs) that indicate individual slice characteristics for wireless network slices. A wireless UE wirelessly receives the SIBs, selects one of the slices based on user requirements for a user application and the individual slice characteristics for the slices, and transfers UE capability information that indicates the selected slice to the wireless access node. The wireless access node transfers the UE capability information to an Access and Mobility Management Function (AMF). The AMF authorizes the wireless UE for the selected slice and selects Quality-of-Service (QoS) parameters for the wireless UE that correspond to the individual slice characteristics for the selected slice. The AMF transfers signaling to the wireless access node to serve the wireless UE per the selected QoS parameters. The wireless access node wirelessly exchanges user data with the wireless UE per the selected QoS parameters.
