Provided in embodiments of the present invention are a communication method and related device. The method in the embodiment of the present invention comprises: determining, by a vehicle-mounted device, configuration information comprising a first cycle state message transmission parameter and a report trigger condition of a network congestion measurement event; determining, by the vehicle-mounted device, a network congestion indication parameter indicating a congestion level of network environment of the vehicle-mounted device; when the network congestion indication parameter satisfies the report trigger condition of the network congestion measurement event, reporting, by the vehicle-mounted device, network congestion information to a wireless communication station; receiving, by the vehicle-mounted device, a second cycle state message transmission parameter transmitted by the wireless communication station and according to the network congestion information, wherein the second cycle state message transmission parameter reduces the network congestion level with respect to the first cycle state message transmission parameter; and transmitting, by the vehicle-mounted device and according to the second cycle state message transmission parameter, a cycle state message. The embodiment of the present invention effectively relieves a network congestion problem in a vehicle network.
