WitrynaVo5G/VoNR: When 5G Core is deployed, voice is leveraged using the 5G Core functions and IMS, while the 5G use cases are delivered by the NR and the 5G Core. VoWifi: The access agnostic 5G core supports fixed and wireless connectivity that includes licensed, unlicensed, 3GPP and non-3GPP technologies, to deliver converged voice services. Witryna10 lip 2024 · SMF supports fallback to EPS from 5GC for IMS sessions if gNB rejects the dedicated bearer creation with ims-voice-eps-fallback or rat-fallback triggered. For the UE devices not supporting VoNR, the SMF performs a fallback to EPS for voice calls. This includes 5G to EPS handover and dedicated bearer creation in 4G for voice call. ... Each of the functions in the diagram is explained below. The IP multimedia core network subsystem is a collection of different functions, linked by standardized interfaces, which grouped form one IMS administrative network.
