  • generating, by a vehicle terminal, a first security message, wherein the first security message carries message type information;

    adding priority indication information of the first security message to a geographic information layer of a protocol stack of the vehicle terminal according to the message type information to thereby obtain a second security message, the geographic information layer being provided above a Packet Data Convergence Control (PDCP) layer of the protocol stack;

    adding current geographic location (GEO) information and movement attribute information of the vehicle terminal to the geographic information layer, the GEO information including longitude information, latitude information, and altitude information of the vehicle terminal, and the movement attribute information including driving speed information and driving direction information;

    determining, at a Media Access Control (MAC) layer of the protocol stack, a transmission path of the second security message according to the priority indication information; and

    sending the second security message to a recipient by using a physical layer of the protocol stack corresponding to the determined transmission path, so that the recipient performs forwarding processing on the second security message according to the GEO information and/or the movement attribute information.
