Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing satellite communication systems experience inefficient resource utilization due to mobile devices attempting to connect with satellites without knowing the satellite's serviceable access classes, leading to unnecessary bandwidth consumption and processing by both the satellite and the device.

Innovation Solution

A system that determines the access class of a mobile device and compares it with the satellite's serviceable classes, allowing communication only when a match is found, thereby reducing unnecessary requests and conserving bandwidth and processing resources.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If mobile devices request communication with satellites without verifying authorized access classes, then communication availability is improved, but satellite bandwidth consumption and resource usage increase

Engineering Contradiction:

Improvecommunication availabilityVSAvoidsatellite bandwidth consumption

Core Design Contradiction:

Adaptability or versatilityVSLoss of energy

Solution Approach 1:

The patent applies preliminary action by having the satellite broadcast authorized access class information before mobile devices attempt communication. This allows devices to pre-screen their authorization status and avoid initiating communication requests that would be rejected, thereby reducing unnecessary bandwidth consumption while maintaining communication availability for authorized devices

Inventive Principle:

Principle #10Preliminary action

2Ease of operation

If mobile devices send connection requests to satellites without knowing their authorized access class, then ease of operation is improved, but satellite processing power consumption increases

Engineering Contradiction:

Improvecommunication initiation simplicityVSAvoidsatellite processing power

Core Design Contradiction:

Ease of operationVSPower

Solution Approach 1:

The patent implements self-service by enabling mobile devices to autonomously determine their authorization status by comparing their stored access class against the broadcast authorized classes. This self-screening mechanism reduces the burden on satellite processing power by filtering out unauthorized devices before they consume satellite resources, while maintaining ease of operation for authorized devices that can proceed with communication requests

Inventive Principle:

Principle #25Self-service

AI summary

The system obtains an access class associated with a UE, where the access class indicates whether the UE is authorized to communicate with a satellite and stores the access class at the UE. The system obtains broadcast information from the satellite, where the broadcast information indicates one or more access classes authorized to communicate with the satellite. The system determines whether the access class stored at the UE is included in the one or more access classes authorized to communicate with the satellite. Upon determining that the access class is not included in the one or more access classes, the system reduces communication with the satellite by refraining from sending a request to connect to the satellite. Upon determining that the access class is included in the one or more access classes, the system sends the request to connect to the satellite.
