Method and system for broadcasting data messages to a vehicle
First Claim
1. 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.

Abstract
The invention provides systems and methods for targeting broadcast messages to particular vehicles or classes of vehicles. In one embodiment, the system comprises an information center for creating and sending a broadcast data message, and a relay section that receives the broadcast data message and relays the message to a plurality of vehicles. The information center typically comprises a one-to-many communication system for sending the message from one source to a plurality of receivers, such as a satellite radio network or the like. The message can be deleted or modified in response to commands received by the receiver.

6. A method for creating and broadcasting a single-packet broadcast data message to at least one vehicle, comprising:
-
receiving a data packet directed to the at least one vehicle having a characteristic; generating a filter code section based on the characteristic; concatenating the data packet and the filter code to generate a broadcast data portion; concatenating the broadcast data portion with a header to generate the single-packet broadcast data message; and broadcasting the single-packet broadcast data message to the at least one vehicle via a one-to-many communication system. - View Dependent Claims (7, 8, 9, 10, 11)
