Various examples of network operation and configuration are described herein. In some examples, UE 101 executes a low-latency application like augmented-reality, vehicle-navigation, remote keyboard, or some other user data service. AS 115 serves the low latency-application in UE 101 based on UE application context for UE 101. The UE application context characterizes the current user session with data like application version, session ID, user ID, session pointers, and other application session metadata. Initially, source AS 115 transfers application data for the low-latency application to source UPF 113 based on the UE application context for UE 101. Source UPF 113 transfers the application data for the low-latency application to source access node 111. Source access node 111 wirelessly transfers the application data for the low-latency application to UE 101. Source access node 111 then initiates a handover of UE 101 to target access node 112—possibly in response to UE mobility. After the UE 101 attaches to target access node 112, source AS 115 transfers application data for the low-latency application to source UPF 113 based on UE application context for UE 101. Source UPF 113 transfers the application data for the low-latency application to source access node 111. Source access node 111 transfers the application data for the low-latency application to target access node 112. Target access node 112 wirelessly transfers the application data for the low-latency application to UE 101.
