Vehicle message addressing
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 method for vehicle messaging, the method comprising:
receiving a formatted group of messages from a messaging interface;
assigning the group of messages to a predetermined channel; and
encoding the group of messages based on:
determining whether one or more wildcards are used in addressing the group of messages to a group of subscribers; and
determining whether a range of vehicle identification numbers (VINs) that respectively correspond to a plurality of subscribers are used in addressing the group of messages to another group of subscribers.

3. The vehicle messaging system of claim 1 , wherein the group of messages correspond to a predetermined subset of subscribers associated with a vehicle having a VIN.
4. The vehicle messaging system of claim 3 , wherein an address associated with the group of messages is encoded using the VIN or a portion of the VIN.
5. The vehicle messaging system of claim 1 , further including a plurality of call receivers that are individually addressable using a predetermined VIN of the range of VINs or addressable in predetermined groups using a portion of a VIN of the range of VINs.
6. The vehicle messaging system of claim 5 , wherein the plurality of call receivers are satellite radio receivers, cellular radio receivers or terrestrial frequency modulated radio receivers.
7. The vehicle messaging system of claim 1 , further comprising:
