Regional Blacklist Management for Relay Device Communication Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication systems face challenges in managing improper devices, such as unstable or malicious devices, which can disrupt services and increase communication bandwidth costs, while also requiring secure data transfer from normal devices without blocking legitimate data.
Innovation Solution
A computer-implemented method and system that utilizes a blacklist to control communication by identifying and isolating improper devices through a relay device network, where information on the position and identifier of improper devices is added to a blacklist, and transferred to nearby relay devices to prevent communication from or to these devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a blacklist is maintained centrally on the server to block improper devices, then communication security is improved, but communication bandwidth and response time deteriorate due to transferring blacklist data to multiple relay devices
Solution Approach 1:
The patent divides the centralized blacklist into multiple regional blacklists, each stored at relay devices covering specific geographic areas. When an improper device is detected, only the regional blacklist corresponding to its location is updated and transferred, rather than distributing the entire blacklist to all relay devices. This segmentation reduces communication bandwidth consumption while maintaining security effectiveness.
Solution Approach 2:
The patent implements location-specific blacklist management where each relay device maintains and updates only the regional blacklist relevant to its geographic coverage area. This local quality approach ensures that blacklist data is transferred only to relay devices that need it based on the position of detected improper devices, optimizing bandwidth usage while preserving communication security.
2Reliability
If the entire blacklist is transferred to all relay devices upon detecting an improper device, then communication control reliability is improved, but communication efficiency and bandwidth utilization deteriorate
Solution Approach 1:
The patent segments the blacklist management process by creating regional blacklists that are geographically distributed across different relay devices. When an improper device is detected, the system identifies the specific region and updates only the corresponding regional blacklist at the relevant relay device, avoiding the inefficiency of transferring the entire blacklist to all relay devices.
Solution Approach 2:
The patent pre-organizes the blacklist into regional segments and pre-assigns them to specific relay devices based on geographic coverage. This preliminary organization enables rapid and targeted updates when improper devices are detected, improving communication efficiency by eliminating the need to transfer and process entire blacklist data across the network.
3Reliability
If position information of improper devices is stored in the blacklist to enable geographic-based blocking, then blocking effectiveness is improved, but device complexity and data management burden increase
Solution Approach 1:
The patent introduces position information as an intermediary key that links improper devices to their geographic regions and corresponding relay devices. This position data enables the system to automatically determine which regional blacklist needs updating without complex decision logic, simplifying data management while maintaining effective geographic-based blocking.
Solution Approach 2:
The patent pre-structures the blacklist system with position information and geographic region mappings established in advance. This preliminary setup allows the system to efficiently manage and update blacklists based on device location without requiring complex real-time analysis, reducing the data management burden while preserving blocking effectiveness.

AI summary
A computer-implemented method, a system, and a computer program product manage a blacklist. The method includes, for a detected improper device, transferring a blacklist or an identifier or identifiers, present in the blacklist, respectively, of one or more devices associated with information on at least one geographic position of associated with a position of the improper device to one or more relay devices which exist at or near the at least one geographic position associated with the position of the improper device. The blacklist is used for controlling commutation or communication from or to the improper device.
