Dynamic Master Station Selection for Interference Mitigation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In communication systems where multiple terminal devices share a common medium, contention protocols lead to inefficiencies due to increased packet collisions, and centralized control protocols struggle to optimize communication quality, especially when external interference occurs, making it difficult to select an optimal master station in dynamic environments like home networks.
Innovation Solution
A terminal device with management capabilities to act as either a master or slave station, which collects and analyzes communication status information to determine the best candidate for master station capability handover, ensuring optimal communication quality by selecting a suitable slave station to handle master station duties under external interference conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a centralized control protocol is used with a fixed master station, then network control efficiency is improved, but communication quality cannot be optimized when external interference occurs
Solution Approach 1:
The patent implements dynamic master station selection by allowing any terminal device to become a master station based on real-time communication status information. This dynamic mechanism enables the system to adapt to external interference by selecting a new master station that is not affected by the interference, thus maintaining both control efficiency and communication quality.
Solution Approach 2:
The patent employs feedback mechanisms where terminal devices report communication status information to potential master stations. This feedback loop allows the system to identify and select a master station that can maintain optimal communication quality, resolving the contradiction between fixed control efficiency and adaptive communication quality.
2Device complexity
If the master station is placed in a physically fixed location, then device complexity is reduced, but adaptability to external interference is worsened
Solution Approach 1:
The system transitions from static to dynamic master station assignment. Any terminal device can become a master station based on communication status information, eliminating the need for predetermined physical placement while maintaining system simplicity through automated selection algorithms.
Solution Approach 2:
The system performs self-organization by automatically selecting a master station based on communication status information without requiring external intervention or complex pre-planning. The terminal devices themselves determine the optimal master station through feedback mechanisms.
3Measurement precision
If communication status information is collected from all slave stations, then master station selection accuracy is improved, but information processing load increases
Solution Approach 1:
The patent extracts only the necessary communication status information from slave stations that is relevant for master station selection. This selective information extraction reduces the processing load while maintaining selection accuracy by focusing on critical parameters such as interference levels and communication quality metrics.
Data Source
AI summary
Terminal devices F and G store statistical information related to interference from an external communication system, and notify the stored statistical information to a master station E. The master station E determines the terminal device G as a candidate station for a master station capability handover destination based on collected statistical information. The master station E requests to hand over a master station capability to the terminal device G. If it is determined that the terminal device G accepts handover of the master station capability, the terminal device G starts to act as the master station.
