Communication Unit Channel Switching for Congestion Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current communication systems rely on fixed network equipment to detect and manage congestion, which inefficiently utilizes resources and lacks knowledge of specific resource requirements for each communication unit, leading to inadequate channel reconfiguration.
Innovation Solution
Each communication unit monitors channel reservation grants to assess expected transmission delays and quality, determining if its Quality of Service (QoS) requirements are met, and if not, scans for alternative channels with suitable resources to switch to, thereby allowing dynamic channel allocation without relying on fixed network equipment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If fixed network equipment monitors congestion on each communication channel, then congestion detection capability is improved, but processing time and resource utilization deteriorate
Solution Approach 1:
Each communication unit independently monitors congestion conditions on communication channels by detecting transmission delays and assessing channel quality. This self-service approach eliminates the need for fixed network equipment to perform congestion monitoring, thereby improving resource utilization while maintaining congestion detection capability.
2Adaptability or versatility
If fixed network equipment reconfigures channel assignments, then channel resource allocation is improved, but knowledge of specific communication unit resource requirements deteriorates
Solution Approach 1:
Communication units autonomously assess their own resource requirements and monitor channel conditions to determine optimal channel assignments. Each unit independently decides when to switch channels based on its specific QoS requirements, eliminating information loss about resource needs while maintaining adaptability through distributed decision-making.
Solution Approach 2:
Each communication unit independently evaluates local channel conditions and its own specific resource requirements, making localized decisions about channel assignment. This distributed approach preserves knowledge of individual unit needs while achieving adaptive channel reconfiguration across the network.
3Productivity
If communication units independently monitor and switch channels, then resource allocation efficiency is improved, but system complexity deteriorates
Solution Approach 1:
Communication units perform self-service by independently monitoring channel conditions and making switching decisions based on their own QoS requirements. This distributed self-service approach improves resource allocation efficiency while avoiding the need for complex centralized control systems.
Solution Approach 2:
Each communication unit is equipped with universal functionality to monitor multiple channels, assess congestion conditions, and autonomously switch between channels. This multi-functional capability enables efficient resource allocation without requiring specialized complex infrastructure.

AI summary
A first communication channel is used by a communication unit for communicating with a base site. The first communication channel has an inbound link and an outbound link. The communication unit determines that congestion is present on the communication channel. The communication unit determines its transmission requirements and whether the first communication channel is capable of supporting its transmission requirements. If the first communication channel is not capable of supporting the transmission requirements of the communication unit, the communication unit locates a second communication channel capable of supporting its transmission requirements, and switches to the second communication channel to communicate with the base site.
