Abstract: Provided are methods and devices for reporting a broadcast state of a warning message. In the method, an evolved Node B (eNB) receives a state request message from a Mobile Management Entity (MME), wherein the state request message is used for requesting to report a broadcast state of a warning message; in response to the state request message, the eNB reports the broadcast state of the warning message to the MME. By means of the technical solution, the effect that a network side can report a broadcast state of a warning message according to a state request from a Cell Broadcast Center (CBC) is achieved.
