Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Aircraft in-flight connectivity communication systems face limitations in data transfer due to restricted bandwidth and cost, necessitating methods to provide differentiated service levels for users.
Innovation Solution
Implementing multiple wireless access points with distinct SSIDs, where data is tagged with differentiated services code points (DSCP) to segregate users and manage service levels, including routing through specific modems, charging, and determining accessible services based on DSCP values.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If bandwidth is increased to provide better service levels, then service quality is improved, but cost increases
Solution Approach 1:
The patent segments the network traffic into different service classes using DSCP tagging, allowing differentiated service levels for different types of data traffic without requiring increased overall bandwidth. This enables quality of service differentiation while maintaining cost efficiency.
Solution Approach 2:
The patent applies local quality by providing different service levels to different data streams based on their specific requirements. Critical data receives higher priority handling while less critical data receives standard service, optimizing resource allocation without uniformly increasing cost across all traffic.
2Adaptability or versatility
If multiple access points with different SSIDs are deployed to segregate users, then service level differentiation is improved, but device complexity increases
Solution Approach 1:
The patent introduces DSCP tagging as an intermediary mechanism that simplifies user segregation. Instead of requiring users to manually select different SSIDs, the system automatically tags data packets with appropriate DSCP values based on user credentials, reducing the complexity of user interaction while maintaining service level differentiation.
Solution Approach 2:
The system implements self-service by automatically assigning DSCP tags to data packets based on user authentication and service level agreements. This eliminates the need for manual user configuration or selection of access points, reducing operational complexity while maintaining adaptability.
3Productivity
If data is routed through specific modems based on DSCP values, then bandwidth utilization is improved, but routing complexity increases
Solution Approach 1:
The patent applies preliminary action by tagging data packets with DSCP values at the point of ingress, before routing decisions are made. This pre-tagging enables downstream routing elements to make efficient modem selection based on already-determined service levels, improving bandwidth utilization without adding complex real-time decision-making logic to the routing process.
Data Source
AI summary
Methods and systems to provide service levels for aircraft in-flight connectivity network systems based on service set identifiers (SSIDs) are disclosed. A disclosed method includes obtaining first data tagged with a first differentiated services code point (DSCP) value, obtaining second data tagged with a second, different DSCP value, and handling the first and second data with different service levels based upon the first and second DSCP values, wherein handling the first and second data with different service levels includes routing the first and second data based upon the first and second DSCP values by routing the first data via a first modem and routing the second data via a second modem.
