Wireless Device Network Dysfunction Reporting via Alternative Radio Properties
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication networks face challenges in detecting and reporting network dysfunction, such as jamming and fraudulent base stations, especially when devices are out of coverage or under interference, as existing methods require direct network access and may be vulnerable to abuse.
Innovation Solution
A method for wireless communication devices to report network dysfunction using alternative radio communication properties, such as pre-defined resource allocations and direct Device-to-Device communication, allowing reports to be sent even when the device is out of coverage or under interference, thereby reducing the risk of detection by malicious entities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If direct network access is required for reporting network dysfunction, then network security and reliability are improved, but the ability to report dysfunction when out of coverage or under interference deteriorates
Solution Approach 1:
The patent introduces a pre-configured alternative reporting mechanism that acts as an intermediary when direct network access is blocked. Devices can report network dysfunction through pre-defined resources (such as out-of-band channels or alternative frequency bands) that do not require normal network access, enabling reporting even when jammed or out of coverage while maintaining security through controlled access procedures.
Solution Approach 2:
The patent implements preliminary configuration of reporting resources and procedures before network dysfunction occurs. Devices are pre-configured with alternative reporting paths, authentication credentials, and resource allocations that can be activated immediately when dysfunction is detected, eliminating the need to establish new communication channels under adverse conditions.
2Adaptability or versatility
If alternative radio communication properties are used for reporting, then the ability to report under interference is improved, but the complexity of communication protocols increases
Solution Approach 1:
The patent changes communication parameters (frequency bands, time slots, power levels, modulation schemes) to alternative values that are less susceptible to interference. By switching to pre-defined alternative radio communication properties such as different frequency bands or time-diverse resources, the system maintains reporting capability without requiring complex real-time adaptation logic.
Solution Approach 2:
The patent segments the reporting function into distinct phases: detection phase (identifying dysfunction), reporting phase (transmitting alerts via alternative properties), and confirmation phase (receiving acknowledgment). This segmentation allows each phase to use optimized, simpler protocols appropriate to its specific function, reducing overall system complexity.
3Reliability
If pre-defined resource allocations are used for reporting, then reporting reliability is improved, but the loss of radio resources for normal communication increases
Solution Approach 1:
The patent allocates radio resources partially - only sufficient resources are reserved for dysfunction reporting rather than dedicating full channels. Pre-defined resource allocations include limited time slots, frequency resources, or power budgets that are just enough to transmit critical alerts, minimizing impact on normal communication while ensuring reporting reliability when needed.
Solution Approach 2:
The patent implements a resource recovery mechanism where pre-defined reporting resources are released back to the normal communication pool after dysfunction reporting is complete or after a timeout period. This dynamic resource management ensures that resources are available for reporting when needed but are not permanently consumed, minimizing overall resource loss.
