Communication Control Device for Wireless Coexistence
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing technologies for secondary usage of frequency channels do not specify which Coexistence Manager (CM) a Coexistence Enabler (CE) should initially connect to, leading to inefficient frequency utilization as information is not supplied to the system, hindering smooth coexistence of communication nodes.
Innovation Solution
A communication control device, storage device, and server device are enhanced to facilitate the selection of a CM based on necessary connection information, allowing the CE to acquire and transmit connection information to the appropriate CM or Coexistence Discovery and Information Server (CDIS), ensuring smooth coexistence of communication nodes across various implementations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a CE is implemented without specifying which CM to connect to first, then the CE can be implemented with flexibility, but information of the secondary usage node cannot be supplied to the system and frequencies cannot be secondarily used smoothly
Solution Approach 1:
The patent applies preliminary action by having CEs proactively transmit their information to a storage device before actual frequency usage begins. This allows the system to pre-establish connection information and select appropriate CMs in advance, ensuring that when frequency secondary usage starts, all necessary connection information is already available and the transition to CM management is smooth and reliable.
Solution Approach 2:
The patent introduces a storage device as an intermediary between CEs and CMs. The storage device collects connection information from multiple CEs, stores it, and provides it to CMs when needed. This intermediary resolves the contradiction by decoupling the CE implementation flexibility from the frequency usage reliability - CEs can implement freely while the storage device ensures proper information supply to the appropriate CM.
2Reliability
If connection information is stored and managed centrally, then frequency secondary usage can proceed smoothly with proper CM selection, but the system complexity increases
Solution Approach 1:
The storage device serves multiple functions: it stores connection information from multiple CEs, manages the information repository, and provides information to multiple CMs as needed. This multi-functionality reduces overall system complexity by consolidating what could be multiple separate management functions into a single universal storage device that handles all connection information management tasks.
3Reliability
If CEs transmit information to multiple CMs, then the system becomes more robust with multiple connection options, but the loss of information increases due to unnecessary transmissions
Solution Approach 1:
The patent implements feedback through the storage device, which maintains a record of which CEs have transmitted information to which CMs. Before transmitting information, the storage device checks whether the receiving CM already possesses the required connection information. This feedback mechanism prevents redundant transmissions, reducing information loss while maintaining connection robustness by ensuring information reaches the appropriate CMs.
