A communication method and system for a Machine-Type Communication (MTC) User Equipment (UE) are disclosed. The method includes that: at least one MTC UE in an MTC UE group receives, based on group paging information received, broadcast information carrying group trigger information from an MTC server, wherein the group trigger information is used for triggering the at least one MTC UE in the MTC UE group; and the at least one UE communicates with the MTC server based on the group trigger information. In the disclosure, the group trigger information is broadcast to the MTC UE group through the broadcast information, so that a plurality of MTC UE in one group is triggered simultaneously, thus optimizing group triggering process, and reducing network resources occupied in the group triggering process.
