Abstract: Provided are a method for instructing update of machine type communication (MTC) system information, a base station (BS) supporting MTC, and a user equipment (UE). The MTC system information comprises system information required by a first-type MTC UE and system information required by a second-type MTC UE. The method comprises: when system information required by a first-type MTC UE is updated and/or system information required by a second-type MTC UE is updated, generating an instruction message containing a related MTC system information update instruction identifier; and sending the generated instruction message. The embodiments of the present invention can reduce the number of times an MTC UE reads the system information, thereby saving on the energy consumption of the MTC UE.
