Responsive to the handover initiation, target access node 112 transfers a handover notice to wireless network core 120. Wireless network core 120 transfers the handover notice to target UPF 114. Target UPF 114 transfers the handover notice to target AS 116. Target AS 116 retrieves the UE application context for UE 101 from source AS 115 based on the handover notice. Target AS 116 applies the retrieved UE context for UE 101 to additional data for the low-latency application. Target AS 116 and target UPF 114 exchange the additional data for the low-latency application in UE 101. Target UPF 114 and target access node 112 exchange the additional data for the low-latency application in UE 101. Target access node 112 and UE 101 wirelessly exchange the additional data for the low-latency application.
