Coexistence Manager State Machine for Frequency Sharing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current coexistence management systems face challenges in avoiding interference and managing resources efficiently among multiple frequency sharing devices, particularly in congested radio environments with varying wireless services.
Innovation Solution
The proposed solution involves an operating method for a coexistence management system that includes a coexistence manager (CM), coexistence enabler (CE), and coexistence discovery and information server (CDIS), which manage states to facilitate connection requests, information exchange, and event handling to optimize frequency sharing and interference avoidance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple frequency sharing devices operate in congested radio environments, then frequency sharing efficiency needs to be improved, but interference between devices increases
Solution Approach 1:
The patent introduces a Coexistence Manager (CM) as an intermediary entity that mediates between multiple frequency sharing devices. The CM coordinates spectrum access, manages coexistence scenarios, and allocates frequency resources to prevent interference while maintaining high frequency sharing efficiency. This mediator resolves conflicts between devices operating in congested radio environments.
Solution Approach 2:
The patent implements dynamic spectrum access mechanisms where devices can adaptively change their operating parameters based on real-time radio conditions. The coexistence management system dynamically adjusts frequency allocation, transmission power, and access timing to optimize frequency sharing efficiency while avoiding interference in congested environments.
2Productivity
If a coexistence management system manages multiple frequency sharing devices, then resource management efficiency improves, but system complexity increases
Solution Approach 1:
The patent segments the coexistence management system into distinct functional entities: Coexistence Manager (CM), Coexistence Enabler (CE), and Coexistence Discovery and Information Server (CDIS). Each entity has specific responsibilities, allowing the system to manage multiple frequency sharing devices efficiently while distributing complexity across modular components rather than concentrating it in a single complex unit.
3Reliability
If connection management states are implemented for coexistence entities, then connection reliability improves, but communication overhead increases
Solution Approach 1:
The patent implements preliminary connection establishment procedures where coexistence entities exchange connection requests, responses, and engagement information before actual data transmission begins. This preliminary action ensures reliable connection setup with proper state transitions (active, waiting engagement, engaged, request received, request sent), preventing communication failures while managing overhead through structured protocols.

AI summary
Disclosed is an operating method of each entity in a coexistence management system that manages a plurality of frequency sharing devices. To perform operations of respective entities (a coexistence enabler (CE), a coexistence manager (CM), and a coexistence discovery and information server (CDIS)), a state machine of the entities is defined as inactive, active, waiting engagement, engaged, request-sent, and request-received states.
