1. A method of operating a wireless communication system to deliver a wireless data service to a wireless User Equipment (UE) responsive to a Radio Unit (RU) handover of the wireless UE, the method comprising:
a Session Management Function (SMF) transferring SMF signaling to a User Plane Function (UPF) to deliver the wireless data service to the wireless UE;
the UPF receiving the SMF signaling and responsively exchanging user data with the wireless UE over a source RU to deliver the wireless data service to the wireless UE;
a Radio Resource Control (RRC) detecting the RU handover of the wireless UE from the source RU to a target RU and responsively transferring an RU handover notice for the wireless UE for delivery to a Session Management Function (SMF);
the SMF receiving the RU handover notice for the wireless UE and responsively transferring new SMF signaling to the UPF to modify the wireless data service for the wireless UE; and
the UPF receiving the new signaling and responsively exchanging additional user data with the wireless UE over the target RU to deliver the modified wireless data service to the wireless UE.
