Document Type and Number:
WIPO Patent Application WO/2022/116211
Kind Code:
A1
Abstract:
The present application relates to the technical field of communications. Disclosed are an emergency call method and apparatus, a storage medium, and a terminal. The method comprises: first, determining whether a current network device supports establishment of an emergency call on an IMS domain; then, if the current network device supports the establishment of the emergency call on the IMS domain, establishing the emergency call on the IMS domain; and finally, if the emergency call fails to be established on the IMS domain, establishing an emergency call on a CS domain. If the current network device supports the establishment of the emergency call on the IMS domain, it is indicated that the current network allows an emergency call to be established on the IMS domain, so that an emergency call may be preferentially established on the IMS domain, and when an emergency call fails to be established on the IMS domain, an emergency call may also be established on the CS domain, thereby improving the success rate of establishing an emergency call by the terminal, so that the safety of a user when using the terminal in an emergency state is ensured.
