Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current coexistence management systems face challenges in efficiently managing interference and resource allocation among frequency-sharing devices across licensed and unlicensed bands, lacking systematic approaches for optimal frequency efficiency and coexistence analysis.
Innovation Solution
A method for exchanging messages among coexistence enablers, managers, and discovery servers, including ReconfigurationRequest and DeregistrationRequest messages, to manage channel lists, transmission power, and channel classification, enabling efficient resource management and interference avoidance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple frequency sharing devices operate in licensed and unlicensed bands simultaneously, then spectrum utilization increases, but interference between devices increases
Solution Approach 1:
The patent introduces a coexistence manager as an intermediary entity that mediates between multiple frequency sharing devices operating in licensed and unlicensed bands. The coexistence manager receives channel classification information from devices, analyzes potential interferences, and sends reconfiguration requests to adjust operating parameters, thereby resolving the interference problem while maintaining high spectrum utilization
Solution Approach 2:
The patent implements a feedback mechanism where coexistence enablers continuously report channel classification information and operational status to the coexistence manager. The manager processes this feedback and sends reconfiguration requests with updated transmission schedules and power limitations, creating a closed-loop system that dynamically adjusts to prevent interference while maximizing spectrum usage
2Productivity
If dynamic spectrum access technologies are implemented to maximize frequency efficiency, then resource allocation efficiency improves, but system complexity increases
Solution Approach 1:
The patent segments the coexistence management system into distinct functional entities: coexistence enablers at the device level for local monitoring, coexistence managers for centralized coordination, and coexistence discovery and information servers for network-wide information management. This segmentation allows dynamic spectrum access to be implemented efficiently while distributing system complexity across multiple manageable components
Solution Approach 2:
The patent creates universal message formats and protocols that can be applied across different frequency bands and device types. The standardized ReconfigurationRequest message structure with fields for transmission schedules, power limitations, and channel lists provides a multi-functional framework that handles various spectrum access scenarios without requiring separate complex systems for each case
3Manufacturing precision
If coexistence management messages include detailed channel classification information, then resource management precision improves, but message size and processing overhead increase
Solution Approach 1:
The patent applies local quality by including detailed channel classification information only where necessary. The ReconfigurationRequest message includes specific fields such as operating channel lists, transmission power limitations, and transmission schedules only for affected devices and time periods, rather than transmitting complete system states, thereby maintaining precision while reducing overall message size

AI summary
Disclosed are methods of exchanging messages necessary for interaction among entities in a coexistence management system that manages a plurality of frequency sharing devices. Specifically, a method of exchanging messages in a coexistence management system including a coexistence enabler (CE), a coexistence manager (CM), and a coexistence discovery and information server (CDIS) includes generating, by the CM, a ReconfigurationRequest message, sending the ReconfigurationRequest message to the CE, and waiting for a ReconfigurationResponse message from the CE. The ReconfigurationRequest message includes at least one of an operating channel list of a white space object (WSO) served by the CE, a transmission power limitation, a flag indicating whether or not a channel is shared, a transmission schedule, and channel classification information.
