Abstract

Provided are an emergency call method and apparatus, a storage medium, and a terminal, related to the technical field of communications. Firstly, it is determined whether the current network device supports an emergency call established on an IMS domain; then, if the current network device supports the emergency call established on the IMS domain, the emergency call is established on the IMS domain. Finally, if the emergency call established on the IMS domain fails, the emergency call is established on the CS domain. If the current network device supports the emergency call established on the IMS domain, it represents that the current network allows the emergency call established on the IMS domain, so the emergency call can be prioritized to be established on the IMS domain, and when the emergency call established on the IMS domain fails, the emergency call may also be established on the CS domain.
