Patent ID: 7643788

Claim:
A method for creating and broadcasting a multi-packet broadcast data message to a plurality of vehicles, comprising: receiving a first data packet directed to a first vehicle having a first identity characteristic, and receiving a second data packet directed to a second vehicle having a second identity characteristic; assigning a first data serial number to the first data packet, and assigning a second data serial number to the second data packet; generating a first filter code section based on the first identity characteristic, and generating a second filter code section based on the second identity characteristic; concatenating the first filter code, the first data serial number, and the first data packet to generate a first one-to-one portion, and concatenating the second filter code, the second data serial number, and the second data packet to generate a second one-to-one portion; concatenating the first and second one-to-one portions to generate a multi-packet payload section; concatenating the multi-packet payload section with a header to generate the multi-packet broadcast data message; and broadcasting the multi-packet broadcast data message to the plurality of vehicles via a one-to-many communication system.
