Abstract

A method for transmitting a message, a UE and a network side device are disclosed. The method includes: receiving, by a network side device, a message reported by a first user equipment UE, where the first UE is a UE in a preset UE group; identifying the message, reported by the first UE, as an emergency message when the message carries a message identifier of the emergency message; and delivering the emergency message to another UE except the first UE in the preset UE group. After identifying a reported emergency message, a network side may immediately deliver the emergency message to each UE. Because the emergency message does not need to be uploaded to a CN and a server of a management center through the network side for delivering, a transmission delay of the emergency message is reduced, which improves a speed that the UE obtains the emergency message.
