Abstract: This application provides a communications method and device. The communications method includes: determining a first frequency band and a second frequency band in an operating frequency band; and transmitting a first-type frame in the first frequency band, and transmitting a second-type frame in the second frequency band, where the first-type frame is used to carry a first-type service, the second-type frame is used to carry a second-type service, and the second-type frame and the first-type frame have different frame structures. Therefore, in embodiments of the present application, different frame structures are used in different frequency bands in the operating frequency band, and different services are carried by using the different frame structures, thereby meeting transmission requirements of different types of services.

Abstract: An information transmission system includes a power system control center, a network device, a transmission device, and at least one system terminal. The network device belongs to a wide area network. Some or all system terminals of the at least one system terminal are configured to send at least one first report message to the transmission device, where the at least one first report message is transmitted using a first network transmission protocol. The transmission device is configured to send at least one second report message to the power system control center using the network device based on information in the at least one first report message, where the at least one second report message is transmitted using a second network transmission protocol different from the first network protocol.
