Telematics Request Filtering for Mobile Vehicle Communication Sessions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In mobile vehicle communication systems, unintentional and excessive requests to establish communication sessions between telematics units and remote facilities can lead to unnecessary resource allocation, as the remote facility is unaware of telematics unit malfunctions, resulting in inefficient use of resources.
Innovation Solution
A method and system that process requests to establish wireless communication sessions by determining if less than a predetermined number of requests have been received from a sender within a specific time period, thereby avoiding unnecessary session establishment and identifying senders that should not initiate communication sessions due to excessive requests.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the remote facility establishes communication sessions in response to every received request, then all legitimate communication requests are fulfilled, but resources are unnecessarily allocated when requests are sent due to telematics unit malfunctions
Solution Approach 1:
The system performs preliminary analysis of request patterns before establishing communication sessions. By monitoring and counting requests from each telematics unit over time, the system proactively identifies malfunctioning units that send excessive requests, and prevents resource allocation to these units before unnecessary communication sessions are established. This preliminary filtering action resolves the contradiction by maintaining reliable communication for legitimate requests while blocking resource-wasting requests from malfunctioning units.
2Loss of energy
If the remote facility monitors and filters excessive requests from senders, then unnecessary resource allocation is reduced, but the system complexity increases due to request tracking and analysis mechanisms
Solution Approach 1:
The system implements a feedback mechanism where the remote facility monitors request patterns from each telematics unit and uses this information to make intelligent decisions about session establishment. The system counts requests over time periods, compares them against thresholds, and adjusts its behavior accordingly - establishing sessions for normal request patterns while blocking excessive requests. This feedback-based approach resolves the contradiction by using simple counting and threshold comparison logic rather than complex analysis, achieving effective filtering with minimal added system complexity.

AI summary
A method of processing requests to establish wireless communication sessions in a mobile vehicle communications system. The method comprises receiving a request to establish a communication session between a telematics unit of a vehicle and a remote facility, wherein the request takes the form of one or more electrical signals. The method further comprises determining whether less than a predetermined number of requests to establish a communication session between the telematics unit and remote facility have been received from the sender of the request within a predetermined period of time. When it is determined that less than the predetermined number of requests have been received from the sender within the predetermined period of time, the method still further comprises establishing a communication session between the telematics unit and the remote facility. A system for performing or utilizing the above-described methodology is also provided.
