Abstract
A terminal first connects to a 5th generation (5G) standalone (SA) network and initiates a call to another terminal by using a Voice over New Radio (VoNR) technology. When the terminal fails to call the other terminal, the terminal disconnects from the 5G SA network, connects to a Long-Term Evolution (LTE) network, and then automatically initiates a call to the other terminal by using a Voice over LTE (VoLTE) technology.
