Solution Overview

Problem

In wireless communication systems, the selection of optimal wireless links in a shared communication frequency band is challenging due to interference and congestion issues among multiple protocols, leading to suboptimal performance and increased energy consumption.

Innovation Solution

A context-aware radio resource management system that includes a concurrent wireless link optimization system, which assesses interference, congestion, and usage trends to determine optimal wireless links by broadcasting RF band local QoS reports on an unlicensed channel, allowing mobile devices to select the best available links for efficient communication.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If multiple protocols operate in shared frequency bands, then communication versatility is improved, but interference and congestion increase

Engineering Contradiction:

Improvecommunication versatilityVSAvoidinterference and congestion

Core Design Contradiction:

Adaptability or versatilityVSObject-affected harmful factors

Solution Approach 1:

The patent introduces QoS advertising messages as an intermediary information carrier that mediates between multiple protocols operating in shared frequency bands. These messages convey channel usage status, interference levels, and congestion information, enabling protocols to coordinate their operations and select optimal transmission opportunities, thereby reducing interference while maintaining versatility

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The system implements feedback mechanisms where devices broadcast QoS advertising messages that provide real-time information about channel conditions, interference levels, and protocol usage. This feedback enables dynamic adjustment of transmission parameters and protocol selection, allowing the system to adapt to changing conditions and minimize interference among multiple protocols

Inventive Principle:

Principle #23Feedback

2Reliability

If devices continuously monitor and select optimal wireless links, then communication quality is improved, but energy consumption increases

Engineering Contradiction:

Improvecommunication qualityVSAvoidenergy consumption

Core Design Contradiction:

ReliabilityVSUse of energy by moving object

Solution Approach 1:

The patent employs preliminary action by having devices broadcast QoS advertising messages in advance that contain pre-assessed channel quality information, interference levels, and recommended protocol selections. When a device needs to communicate, it can directly use this pre-prepared information to quickly select optimal links without performing extensive real-time monitoring, thereby maintaining communication quality while reducing energy consumption

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system applies partial action by having devices monitor and broadcast QoS information only for specific frequency bands and protocols that are actively being used or are likely to be used. Instead of continuously monitoring all possible channels, devices perform selective monitoring based on current communication needs and historical usage patterns, reducing the overall monitoring burden and energy consumption while maintaining adequate communication quality

Inventive Principle:

Principle #16Partial or excessive action

3Loss of information

If QoS advertising messages are broadcast on unlicensed channels, then information availability is improved, but channel congestion increases

Engineering Contradiction:

Improveinformation availabilityVSAvoidchannel congestion

Core Design Contradiction:

Loss of informationVSQuantity of substance

Solution Approach 1:

The patent segments the QoS advertising functionality by allocating different types of QoS information to different communication channels and protocols. Critical QoS messages are transmitted on unlicensed channels where they provide valuable information, while less critical information is conveyed through other means. This segmentation reduces the information load on any single channel, minimizing congestion while maintaining comprehensive information availability

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The system implements periodic action by having devices broadcast QoS advertising messages at specific intervals rather than continuously. The broadcasting frequency is adjusted based on the rate of change of channel conditions and the current level of congestion. This periodic approach ensures that information remains relatively current while reducing the total volume of traffic on the channel, thereby balancing information availability with congestion management

Inventive Principle:

Principle #19Periodic action
