A method, a device, and a system for receiving an emergency event alert are provided, which relate to a field of communication applications. As long as communication between a user terminal and a bearer network is normal, no matter whether the user terminal is watching live television programs, the user terminal can receive the emergency event alert in time. The method is as follows. A receiving unit discovers an emergency event alert service. The receiving unit is attached to the emergency event alert service. The receiving unit receives an emergency event alert message sent by a distributing unit. An emergency event alert receiving unit device includes a discovering and processing module, a service attachment processing module, and a message reception processing module. Through attachment to the emergency event alert service, the user terminal can receive the emergency event alert in time.
