The present invention provides a method for sending a trigger message, and a device. When a third-party application server AS needs to establish a connection with machine-to-machine communications user equipment M2M UE, the third-party AS sends a trigger trigger message to a device trigger application server DT-AS, where the trigger message includes at least an identifier of the machine-to-machine communications user equipment M2M UE. The DT-AS determines, according to the identifier of the M2M UE, whether the M2M UE has registered with a network at which the DT-AS is located, and if the M2M UE has registered with the network at which the DT-AS is located, sends the trigger message to the M2M UE, so as to implement that the DT-AS identifies the trigger message, so that the M2M UE establishes a connection with the third-party AS. |
