Base Station Displacement Detection Using Terminal Measurement Reports
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems for detecting displacement of micro-mini base stations in wireless communication networks face issues such as failure to detect displacement without GPS-enabled devices and interruption of wireless communication services when monitoring radio waves from other base stations.
Innovation Solution
A wireless base station system that requests and receives measurement reports from connected wireless terminals regarding signal reception states from nearby base stations, using this information to determine if the base station has been displaced, without relying on GPS signals or interrupting wireless communication services.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the base station monitors radio waves from other base stations to detect displacement, then displacement detection capability is improved, but wireless communication service is interrupted
Solution Approach 1:
The base station performs preliminary actions by requesting measurement reports from wireless terminals before displacement occurs. The system establishes a baseline of signal reception states from neighboring base stations and compares subsequent measurements against this baseline to detect displacement without requiring continuous monitoring that would interrupt service.
Solution Approach 2:
The patent introduces wireless terminals as intermediaries to detect displacement. Instead of the base station directly monitoring radio waves from other base stations (which would interrupt service), the base station requests measurement reports from wireless terminals about signal reception states. These terminals act as mediators that provide displacement information without interfering with normal communication services.
2Measurement precision
If the system relies on GPS signals for displacement detection, then detection accuracy is improved, but the system fails when GPS signals are unavailable
Solution Approach 1:
The system uses self-service by leveraging the wireless terminals' existing capability to measure signal reception states from neighboring base stations. Instead of relying on external GPS services, the system utilizes the terminals' own measurement functions to detect displacement, making the system self-sufficient and adaptable to environments where GPS is unavailable.
Solution Approach 2:
The patent applies universality by making wireless terminals serve multiple functions: they not only perform their primary communication function but also act as displacement detection sensors. The terminals' existing signal measurement capabilities are repurposed to detect base station displacement, eliminating the need for dedicated GPS receivers or separate detection systems.

AI summary
A wireless base station includes a storage unit and a processor. The processor transmits to a first wireless terminal a first request for transmitting a first response including first identifiers used to identify a first base stations. The first wireless terminal is capable of receiving a signal from each of the first base stations. The processor receives the first response from the first wireless terminal. The processor stores the first response in the storage unit. The processor transmits to a second wireless terminal a second request for transmitting a second response including second identifiers used to identify second base stations. The second wireless terminal is capable of receiving a signal from each of the second base stations. The processor receives the second response from the second wireless terminal. The processor determines whether the wireless base station has been displaced based on the first identifiers and the second identifiers.
