AMF 421 receives an N2 path switch request for UE 401 from target CU 416. In response, AMF 421 transfers path switch instructions to core SMF 422 to switch UE 401 from source CU 415 and UPF 431 to target CU 416 and UPF 432. SMF 422 transfers N4 signaling to target UPF 434 that directs UPF 434 to exchange low-latency communications for UE 401 between target CU 416 and target ASF 434 for the low-latency application. In response to the path switch for the low-latency application, SMF 422 identifies source UPF 421 and the low-latency application to target UPF 432 over N4 signaling. AMF 421 and target CU 416 exchange N2 signaling that directs CU 416 to serve UE 401 with the low-latency communications to target UPF 432. NRF 423 receives the IDs for source UPF 431 and the low-latency application from CU 416. NRF 423 translates the IDs for source UPF 431 and the low-latency application into an ID for source ASF 433. Core NRF 423 indicates the ID for source ASF 433 to target CU 416.
