WebUser experience of EPS FB is similar to that of 4G CSFB. If the UE camping on the 5G NR network makes a call, the voice/video communication and data services fall back to the 4G network. The connection duration is 1 to 2 seconds longer than that of the VoNR. However, there are differences between user experience of EPS FB and that of 4G CSFB. WebNov 6, 2024 · That means iRNL cause can be redirection/CSFB. My question is that ERAB is already established so RNL should trigger SRVCC, no ? Why a redirection or csfb ? since simply put…csfb is service HO while SRVCC is coverage HO. So if UE has a QCi1 ERAB and it is lost, then why not a SRVCC ? highchart property
