    abstract =  {This document describes evolution of mobile user plane in 5G, including distributed UPFs and alternative user plane implementations that some vendors/operators are pushing without changing 3GPP architecture/signaling. This also sets the stage for discussions in a companion document about potentially integrating UPF and Acess Node (AN) in a future generation (xG) of mobile network.},
