Abstract

A method, an apparatus, and a system for implementing alarm event handling. The method includes: acquiring, by a first NodeB eNB, alarm event EM information reported by a user terminal UE; sending, by the first eNB, an EM notification that includes the EM information to at least one eNB that needs to be notified of the EM information, so that the at least one eNB sends the EM notification to a UE of the at least one eNB; and sending, by the first eNB, the EM notification that includes the EM information to a UE of the first eNB. By using the method, the apparatus, and the system according to the embodiments of the present invention, a signaling interaction process for alarm event handling in an emergency case is shortened, thereby greatly shortening a communications delay of a cellular network communications system and greatly reducing system load.
