Vehicle Message Addressing via VIN-Based Satellite Targeting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current satellite radio systems lack the ability to efficiently address and target specific vehicles or groups of vehicles using vehicle identification numbers (VINs), leading to inefficient bandwidth usage and inability to deliver targeted messages effectively.
Innovation Solution
A vehicle messaging system and method that utilizes a selective call receiver and decoder to address vehicles using their VINs, allowing for decoding of messages to specific, grouped, or all vehicles through wildcard data, enabling targeted message delivery via satellite uplink and selective call receivers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If satellite radio systems broadcast messages to all vehicles without addressing capabilities, then all vehicles can receive the same content, but bandwidth is wasted transmitting messages to vehicles that are not the intended targets
Solution Approach 1:
The patent segments the broadcast audience by dividing vehicles into specific target groups based on VIN patterns. Instead of treating all vehicles uniformly, the system segments them by manufacturer, model, year, or custom groups, allowing selective addressing. This enables the system to target only relevant vehicles with specific messages, reducing bandwidth waste while maintaining the ability to reach appropriate audiences.
Solution Approach 2:
The patent implements local quality by allowing different addressing methods for different message types and vehicle groups. Individual VIN addressing is used for vehicle-specific messages, while group addressing using wildcards is used for manufacturer-wide or model-wide announcements. This differentiated approach optimizes bandwidth usage by matching the addressing granularity to the message scope.
2Measurement precision
If the system uses individual VIN addressing for every vehicle, then precise targeting is achieved, but the system complexity increases significantly
Solution Approach 1:
The patent reduces system complexity by segmenting addressing into two distinct modes: individual VIN addressing for precise targeting and group addressing using wildcards for broader campaigns. This segmentation allows the system to avoid the complexity of managing individual addresses for every vehicle when group targeting suffices, while still maintaining precise individual addressing capability when needed.
Solution Approach 2:
The patent implements universality by designing a dual-mode addressing system that can handle both individual VIN targeting and group targeting through wildcards. This multi-functionality allows the same system infrastructure to support diverse messaging scenarios without requiring separate systems, thereby managing complexity while maintaining precision when needed.
3Area of stationary object
If satellite radio systems pre-install receivers in all vehicles, then coverage is maximized, but the ability to deliver targeted messages to specific vehicles or groups is lost
Solution Approach 1:
The patent segments the universal broadcast capability into targeted delivery by enabling the system to identify and address specific vehicle groups within the broader coverage area. The segmentation is achieved through VIN-based addressing that can filter and target vehicles by manufacturer, model, year, or custom groups, allowing the system to maintain wide coverage while delivering targeted information to specific segments.
Solution Approach 2:
The patent introduces VIN-based addressing as an intermediary between the broadcast system and individual vehicles. This intermediary mechanism enables the system to translate broad coverage capability into targeted message delivery by using VIN patterns and wildcards as a mediating layer that connects the universal broadcast infrastructure with specific vehicle groups.
Data Source
AI summary
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.
