A method includes: receiving an emergency call request; initiating, according to the emergency call request, n emergency calls by simultaneously using n call modes, where n is an integer not less than 2; and when a connection is established for one of the n emergency calls, releasing other emergency calls for which no connection has been established. By means of the embodiments of the present invention, multiple emergency calls may be simultaneously made, and when any one of the multiple emergency calls is connected, other emergency calls are released, reducing an emergency call time.
