When executed in CU 415, source UPF 431 registers its ID with NRF 423 in core 420 and indicates its ability to communicate with source ASF 433. When executed in CU 415, source ASF 433 registers its ID with NRF 423 in core 420 and indicates its ability to serve the low-latency application. UE 401 and RRCF 513 in source CU 415 wirelessly exchange attachment signaling over source RU 411 and DU 413. RRCF 513 in source CU 415 and AMF 421 in core 420 exchange N2 attachment signaling for UE 401. AMF 421 and UE 401 exchange authentication signaling over source RU 411, DU 413, and CU 415.
SMF 422 in core 420 and source UPF 431 exchange N4 signaling that directs UPF 431 to serve UE 401 with low-latency communications to source ASF 433. AMF 421 in core 420 and RRCF 513 in source CU 415 exchange N2 signaling that directs CU 415 to serve UE 401 with the low-latency communications.
UE 401 and source RU 411 wirelessly exchange low-latency data for the low-latency application. Source RU 411 and source DU 412 exchange the low-latency data. Source DU 413 and source CU 415 exchange the low-latency data responsive to the signaling from AMF 421 in core 420. SDAPF 512 in source CU 415 and source UPF 431 exchange the low-latency data responsive to the signaling from AMF 421 and SMF 422. Source UPF 431 and ASF 433 exchange the low-latency data responsive to the signaling from SMF 422. ASF 433 processes the low-latency data based on UE application context for UE 401.
