To enhance reliability for emergency calls, some networks, such as New Radio 5G Communication (NR5G) networks, provide multiple ways to originate emergency calls, and in particular provide an emergency call fallback (ES-FB) service. However, under some user equipment (UE) configurations and conditions, the ES-FB service is not available, potentially delaying the emergency call. When the UE is in a configuration or condition where ES-FB is potentially available, the UE searches for a network cell that supports emergency service over the IP Multimedia Subsystem (“IMS”), thereby enhancing the speed and reliability of emergency calls.
