Vehicle message addressing
View Patent ↗A vehicle messaging method ( 600 ) and system ( 100 ) can include any number of data sources ( 101 - 103 ), an interface ( 104 ) that formats messages and addresses from the data sources, and a corresponding number of messaging servers ( 111 - 113 ) that receive targeted messages intended for a predetermined subset of subscribers associated with a vehicle identification number (VIN). Each messaging server can include a corresponding controller ( 121 - 123 ) programmed to assign ( 604 ) targeted messages to a predetermined channel and encode ( 606 ) the addresses of the targeted messages to the predetermined subset of subscribers using a VIN or portion thereof. The controller can be further programmed to transfer ( 608 ) the targeted messages and addresses to a satellite uplink ( 107 ) and satellite ( 110 ) via a messaging uplink interface ( 106 ) for retransmission and reception by a plurality of selective call receivers 109 addressable individually using a predetermined VIN or portion thereof.
1. A vehicle messaging device, comprising:
a selective call receiver;
a decoder coupled to the selective call receiver, wherein the decoder is programmed to:
determine if a received address associated with a message received at the selective call receiver is based at least in part on a stored vehicle identification number;
decode the message if the received address includes a vehicle identification number that matches the stored vehicle identification number;
decode the message if the received address includes a range of vehicle identification numbers and if the stored vehicle identification number is included in the range of vehicle identification numbers; and
decode the message if the vehicle identification number of the received address and a hardware identifier of the received address match the stored vehicle identification number and a stored hardware identifier.
2. The vehicle messaging device of claim 1 , wherein the selective call receiver is a satellite digital audio radio, a terrestrial frequency modulated radio, or a cellular radio receiver.
3. The vehicle messaging device of claim 1 , wherein the decoder is further configured to decode a broadcast message to all vehicles if the received address has wildcard data that matches a stored address.
4. The vehicle messaging device of claim 1 , wherein the stored vehicle identification number is obtained over a vehicle's communication bus.
5. The vehicle messaging device of claim 1 , wherein the decoder is further configured to determine if the received address is based on a subscriber identifier, a hardware identifier, or a group identifier.
6. The vehicle messaging device of claim 1 , wherein the decoder is further configured to determine if the received address is based on a subscriber identifier, a hardware identifier, a group identifier or any combination thereof.
7. The vehicle messaging device of claim 1 , wherein the vehicle messaging device can be addressed with a message to a single vehicle identification number, to multiple vehicle identification numbers using wildcards, or a plurality of vehicle identification numbers using a range of vehicle identification numbers.
8. The vehicle messaging device of claim 1 , wherein the message is a command and control message, a service message, a service authorization message, a software or firmware update, a file download, a text message, an audio message, an image, or a video.
9. A vehicle messaging system, comprising:
a messaging server configured to receive targeted messages, each of the targeted messages being intended for a predetermined subset of subscribers associated with at least one vehicle, and each of the at least one vehicle having a respective vehicle identification number; and
a controller coupled to the messaging server, wherein the controller is configured to:
assign the targeted messages from a predetermined manufacturer to a predetermined channel; and
encode, for at least one targeted message, an address for that message using a specific vehicle identification number and a specific hardware identifier.
10. The vehicle messaging system of claim 9 , wherein the controller is further configured to transfer the targeted messages and encoded addresses to a satellite uplink for transmission of the targeted messages and encoded addresses to one or more satellites for retransmission to a predetermined satellite coverage area.
11. The vehicle messaging system of claim 9 , wherein the system further comprises a plurality of selective call receivers addressable individually using a predetermined vehicle identification number or in predetermined groups using a portion of a vehicle identification number.
12. The vehicle messaging system of claim 11 , wherein the plurality of selective call receivers each comprises a decoder coupled to a selective call receiver, wherein the decoder is configured to:
determine if a received address associated with a message received at the selective call receiver is based at least in part on a stored vehicle identification number;
decode the message if the received address includes a vehicle identification number that matches a specific the stored vehicle identification number;
decode the message if the received address includes a range of vehicle identification numbers and if the stored vehicle identification number is included in the range of vehicle identification numbers; and
decode the message if the vehicle identification number of the received address and a hardware identifier of the received address match the stored vehicle identification number and a stored hardware identifier.
13. The vehicle messaging system of claim 12 , wherein the selective call receiver is a satellite digital audio radio, a terrestrial digital frequency modulated radio, or a digital cellular radio receiver.
