Disclosed is a method for sending a trigger message, including steps as follows: a Machine Type Communication InterWorking Function (MTC-IWF) authenticates a Machine Type Communication (MTC) server upon receiving a trigger message sent by the MTC server; obtains, after the MTC server is authenticated, an Internet Protocol (IP) address of an MTC User Equipment (UE); sends, when the IP address of the MTC UE is obtained, the trigger message to the MTC UE via a user plane network node equipment according to the obtained IP address of the MTC UE, or sends, when the IP address of the MTC UE is not obtained, the trigger message to the MTC UE via a control plane interface; and sends a trigger confirm message to the MTC server. The present disclosure also provides a system and equipment for sending a trigger message. With a technical solution according to the present disclosure, it is possible to send a trigger message. |
