Provided in the present invention are an M2M data query and scheduling method, query and scheduling device and system. The query method comprises: transmitting a data scheduling request to an infrastructure node common service entity (infrastructure node CSE), where the data scheduling request comprises an application entity/common service entity identifier (AE/CSE ID) for data scheduling and a data requirement for data scheduling, the data requirement comprises a data type requirement, a time requirement or a combination thereof; and, receiving data returned by the infrastructure node CSE and satisfying the data requirement. The present invention prevents the occurrence of a scenario in which excessive instances of command requests are present between an application node and an intermediate node. This reduces byte overhead for interactive signaling between the application node and the intermediate node and reduces the time for data query and the time for data scheduling, thus increasing the efficiencies in data query and in data scheduling. |
