Provided are a policy control method and device for one or more terminal peripherals. The method includes: an M2M gateway executing one or more operations for one or more terminal peripherals according to a transaction trigger condition in policy definition, wherein the one or more operations for the one or more terminal peripherals are one or more operations corresponding to the transaction trigger condition in the policy definition. The solution solves the technical problem in the related art that it is impossible to implement control for one or more terminal peripherals through the M2M gateway according to the policy definition, which implements policy control of one or more terminal peripherals through the M2M gateway and improves the intelligent degree of an M2M system.
