1. A method to serve a wireless User Equipment (UE) over a working network slice and a protect network slice, the method comprising:
receiving UE capability data from the wireless UE that indicates the working network slice and the protect network slice, wherein the working network slice comprises a working User Plane Function (UPF) and the protect network slice comprises a protect UPF;
determining UE context for the working network slice and for the protect network slice by determining a working network address for the working network slice and determining a protect network address for the protect network slice;
exchanging initial user data with the wireless UE over the working network slice based on the UE context; and
exchanging additional user data with the wireless UE over the protect network slice based on the UE context when performance of the working network slice triggers a slice switch based on the UE context.
