Wireless Base Station Configuration Sharing for Fast Handover
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication technologies, such as the active scan method, are inefficient for initializing wireless LAN services and require learning over time, which hinders fast switching between multiple wireless base stations, especially when multiple base stations are present.
Innovation Solution
A communication apparatus and method that acquire configuration information from other wireless base stations to generate sharing verification information, allowing for efficient active scans by frequency-multiplexing probe responses based on common and unique configuration information, enabling faster handover between base stations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the active scan method is used to select optimal wireless base stations, then wireless LAN services can be established, but the initialization process requires learning over time and cannot be used for fast switching between base stations
Solution Approach 1:
The patent applies preliminary action by having wireless base stations pre-generate and store configuration information lists before actual communication occurs. When a terminal requests service, the base station can immediately provide pre-prepared configuration data without needing to learn or scan in real-time, thus eliminating the initialization learning period while maintaining service establishment capability
Solution Approach 2:
The patent implements beforehand cushioning by creating backup configuration information lists that are stored in advance at each wireless base station. These pre-prepared lists act as a cushion that allows fast switching between base stations without requiring time-consuming learning processes, as the necessary configuration data is already available and verified
2Speed
If configuration information is shared between multiple wireless base stations, then fast switching is enabled, but verification of configuration commonality becomes necessary
Solution Approach 1:
The patent applies copying by having wireless base stations create copies of configuration information lists from a master list or from each other. Instead of complex real-time verification, each base station maintains a copied version of the configuration data, which can be quickly provided to terminals. The copying process includes generating verification information to ensure the copies match the original, simplifying the verification complexity while enabling fast switching
