Abstract: This disclosure relates to a communication method and an apparatus, applied to an internet of vehicles, for example, V2X, LTE-V, and V2V. An in-vehicle apparatus triggers an on-board function for a first vehicle. The first vehicle carries the in-vehicle apparatus. The in-vehicle apparatus checks whether the first vehicle is allowed to use the on-board function on a first road. When the first vehicle is on the first road, the in-vehicle apparatus enables or disables the on-board function based on a check result. In the embodiments of this disclosure, whether to enable a corresponding on-board function may be controlled, so that the on-board function is enabled without depending on a human requirement. In this way, the corresponding on-board function may be controlled to be applied to an appropriate road, to reduce a vehicle accident risk, and a danger to social security.

Abstract: The present disclosure provides a method of sending a vehicle-to-everything (V2X) service message. The method includes: determining, by a terminal device, a communication path for a V2X service, where the communication path is selected from at least two communication paths, the at least two communication paths include a first communication path and a second communication path, the first communication path is a communication path on which communication is performed using a PC5 interface, and the second communication path is a communication path on which communication is performed using a Uu interface; and sending, by the terminal device, a message of the V2X service by using the communication path. In the foregoing solution, the communication path can be selected from the at least two communication paths, to send the message of the V2X service. In this way, a communication path is flexibly selected for a V2X service.
