Feature Description

The UPF supports Voice over New Radio (VoNR) with the existing Session Establishment and Modification procedures. In these procedures, the SMF creates the PDR for 5QI=5 Non-GBR flow for IMS signaling and PDR for 5QI=1 GBR flow for voice traffic. The UPF does not require any special handling to support mobile-originated or mobile-terminated call flows.
