Radio Communication Device for Unknown Base Station Discovery
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for collecting base station information in radio communication apparatuses are inefficient as they rely on the movement path of the device, leading to a lack of new base station information being collected, especially when the device only moves near known base stations, and struggle with indoor or underground positioning due to GPS limitations.
Innovation Solution
A radio communication apparatus that notifies the user of unknown base station positions, allowing the device to be moved to their vicinity, receives and records base station identification information, and associates this information with position data, enabling efficient collection and subsequent position estimation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If base station information is collected by conventional methods relying on movement path, then the device can acquire base station data during normal operation, but the collection efficiency is low and no new base station information is obtained when the device only moves near known base stations
Solution Approach 1:
The notification unit notifies the user in advance about unknown base stations and their positions before the device reaches them. This preliminary notification allows the user to intentionally move the device to these locations, ensuring that base station information is collected proactively rather than passively during random movement, thereby improving collection efficiency and discovering new base stations.
2Measurement precision
If GPS positioning is used for position estimation, then satellite-based location data can be obtained, but it takes a long time to supplement synchronization during activation and cannot be used indoors or underground where satellite signals are not receivable
Solution Approach 1:
The invention uses base stations as intermediary reference points for position estimation instead of relying directly on satellite signals. By collecting base station identification information and their positions, the system can estimate the device's location through wireless LAN signals that penetrate indoor and underground environments, thereby maintaining positioning adaptability while achieving measurement precision through the base station network.
3Adaptability or versatility
If wireless LAN position estimation technology is used, then indoor or underground position estimation is enabled, but base station information must be registered in advance which requires efficient collection methods
Solution Approach 1:
The notification unit enables the system to self-improve by automatically identifying unknown base stations and notifying users to collect their information. This self-service mechanism reduces the complexity of manual base station registration by allowing the system to autonomously discover and guide collection of new base station data, thereby simplifying the overall information registration process while maintaining indoor positioning adaptability.
