Abstract:
1. A method for sending Machine Type Communication (MTC) device trigger information, comprising: an MTC server setting contents of the MTC device trigger information and sending the MTC device trigger information to a network node equipment; the network node equipment searching a core network equipment corresponding to a target user equipment and forwarding the MTC device trigger information to the core network equipment; the core network equipment forwarding the MTC device trigger information to the target user equipment via a Radio Access Network (RAN); and the target user equipment receiving the MTC device trigger information and sending an MTC device trigger information acknowledgement message to the core network equipment; wherein the contents of the MTC device trigger information comprises: an MTC device identifier and an MTC device trigger validity period; wherein the MTC device identifier is an external identifier of 3rd Generation Partnership Project (3GPP) network, a corresponding internal identifier of the 3GPP network is International Mobile Subscriber Identity (IMSI), and the mapping between the external identifier and the internal identifier is completed by an MTC InterWorking Function (MTC-IWF), or a Home Subscriber Server (HSS), or a Home Location Register (HLR); wherein sending the MTC device trigger information to the network node equipment comprises: deriving the internal identifier of the 3GPP network IMSI, according to the MTC device identifier in the contents of the MTC device trigger information, searching the network node equipment corresponding to the target user equipment according to the internal identifier of the 3GPP network IMSI, and sending the MTC device trigger information to the network node equipment.
