A wireless communication system to deliver a wireless data service to User Equipment (UE) responsive to a handover of the UE, the wireless communication system comprising:

• a Radio Access Network Centralized Unit (RAN CU) configured to transfer a handover registration to a Network Repository Function (NRF);
• a Session Management Function (SMF) configured to transfer a handover subscription for the UE to the NRF;
• the NRF configured to receive the handover registration and the handover subscription;
• the RAN CU configured to detect a handover of the UE and responsively transfer a handover notice for the UE to the NRF;
• the NRF configured to receive the handover notice for the UE, and in response to the handover subscription for the UE from the SMF, transfer the handover notice for the UE to the SMF;
• and
• the SMF configured to modify the wireless data service for the UE responsive to the handover notice for the UE.
