UE 401 and target RU 412 now wirelessly exchange low-latency data for the low-latency application. Target RU 412 and target DU 414 exchange the low-latency data. Target DU 414 and target CU 416 exchange the low-latency data responsive to the N2 signaling from AMF 422. Target CU 416 and target UPF 432 exchange the low-latency data responsive to the N2 signaling from AMF 421 and the N4 signaling from SMF 422. Target UPF 432 and ASF 434 exchange the low-latency data to serve the low-latency application in UE 401 based on the retrieved UE application context for UE 401.

FIG. 5 illustrates source Radio Unit (RU) 411, Distributed Unit (DU) 413, and Central Unit (CU) 415 to handover wireless UE 401 that executes the low-latency application. RU 411, DU 414, and CU 416 comprises an example of wireless access node 111, although node 111 may differ. Source RU 411 comprises antennas, amplifiers, filters, modulation, analog-to-digital interfaces, DSP, memory, and transceivers (XCVRs) that are coupled over bus circuitry. Source DU 413 comprises memory, CPU, and transceivers that are coupled over bus circuitry. The memory in DU 413 stores an operating system and 5GNR network applications like Physical Layer (PHY), Media Access Control (MAC), and Radio Link Control (RLC). Source CU 415 comprises memory, CPU, and transceivers that are coupled over bus circuitry. The memory in CU 415 stores an operating system and network functions like UPF 432, ASF 434, Packet Data Convergence Protocol Function (PDCPF) 511, Service Data Adaptation Protocol Function (SDAPF) 512, and Radio Resource Control Function (RRCF) 513.
