Satellite Broadcast Authorization via Telematics Feedback Loop
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current satellite broadcast services face inefficiencies in determining the authorization status of mobile vehicle receivers due to one-way communication and the need for repeated administrative commands, especially in mobile environments, leading to wasteful bandwidth usage and user involvement.
Innovation Solution
A method utilizing a call center that sends a request for authorization status to a mobile vehicle's telematics unit, which then communicates with the satellite radio receiver and returns the status to the call center, which subsequently sends it back to the satellite broadcast service, leveraging existing wireless telematics systems for duplex communication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If satellite broadcast service sends administrative commands repeatedly to mobile vehicles, then the statistical likelihood of successful command delivery increases, but satellite broadcast bandwidth is wasted
Solution Approach 1:
The patent implements a feedback mechanism where the mobile vehicle's telematics unit responds to authorization status requests sent by the satellite broadcast service via the call center. This two-way communication allows the service to confirm successful command delivery without repeated transmissions, resolving the contradiction between reliable command delivery and bandwidth efficiency.
Solution Approach 2:
The patent introduces a call center as an intermediary between the satellite broadcast service and mobile vehicles. The call center manages the authorization status requests and responses, coordinating communication to ensure reliable command delivery while optimizing bandwidth usage by consolidating administrative tasks.
2Loss of energy
If satellite broadcast service uses one-way communication for administrative tasks, then bandwidth is conserved, but authorization status cannot be acquired
Solution Approach 1:
The patent transforms one-way satellite-to-vehicle communication into a two-way system by implementing feedback mechanisms. The telematics unit in the mobile vehicle sends authorization status information back to the satellite broadcast service through the call center, enabling status acquisition while maintaining bandwidth efficiency through targeted, on-demand communication.
Solution Approach 2:
The call center serves as an intermediary that enables two-way communication between the satellite broadcast service and mobile vehicles. It receives authorization status requests from the service, forwards them to vehicles, and collects responses, thereby facilitating information acquisition without requiring continuous two-way satellite communication.
3Reliability
If satellite broadcast service requires user alerting when administrative commands fail, then command delivery issues can be addressed, but user involvement increases
Solution Approach 1:
The patent implements self-service functionality where the telematics unit in the mobile vehicle automatically responds to authorization status requests without requiring user intervention. The system autonomously manages administrative tasks, eliminating the need for users to be alerted or take action when commands fail, while maintaining reliable command delivery verification.
Solution Approach 2:
The automated feedback mechanism between the telematics unit and the satellite broadcast service (via the call center) replaces manual user alerting. The system automatically tracks and reports authorization status, ensuring reliable command delivery verification without involving the user in administrative processes.
Data Source
AI summary
The present invention provides a method for determining an authorization status of a satellite broadcast service for a mobile vehicle. A call center receives a request for the authorization status of the satellite broadcast service for the mobile vehicle. The call center sends a request signal to the mobile vehicle. The call center then receives an authorization status signal from the mobile vehicle. The call center then sends the authorization status to the satellite broadcast service.
