Radio Access Point Normality Confirmation via Centralized Test Terminal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing radio communication systems fail to confirm the normality of radio access points including antenna facilities, leading to potential system shutdowns and increased costs due to the need for separate test terminals at each access point.
Innovation Solution
A test terminal (TAT) is installed in one radio access point to connect with adjacent access points, allowing for the confirmation of normality without the need for separate test terminals at each access point, using a maintenance terminal to assess the connection results and display or store the results for judgment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a test terminal is installed in each radio access point apparatus, then the normality of the access point and network can be confirmed, but the cost of the radio access point apparatus per unit increases
Solution Approach 1:
The patent combines the test terminal functions into a single centralized test terminal that can communicate with multiple radio access point apparatuses through the network, rather than installing separate test terminals at each access point. This merging approach maintains the ability to confirm normality of multiple access points while significantly reducing the overall cost and complexity.
Solution Approach 2:
The single test terminal is designed with universal functionality to test multiple radio access point apparatuses sequentially through network communication. The test terminal can identify and communicate with different access points using their identifiers, allowing one terminal to perform the work of multiple terminals would otherwise be needed.
2Ease of operation
If a directional coupler is installed between the radio access point apparatus and the antenna, then the access point can be tested, but the normality of the antenna facility cannot be confirmed
Solution Approach 1:
The patent uses the network as an intermediary medium to transmit test signals from the single test terminal to multiple radio access point apparatuses. This network-based intermediary approach allows the test terminal to communicate with access points without requiring physical connection through directional couplers at each location, thereby enabling comprehensive testing including antenna facility normality confirmation.
3Reliability
If test terminals are installed in each radio access point apparatus, then comprehensive testing can be performed, but the number of access points requiring test terminal installation increases
Solution Approach 1:
The patent merges multiple test terminal functions into a single centralized test terminal that can communicate with multiple radio access point apparatuses through the network. This consolidation reduces the number of access points requiring test terminal installation from multiple individual installations to a single location, while maintaining comprehensive testing capability through network-based communication.

AI summary
The normalities of access points including antenna facilities thereof are confirmed.An access point includes a terminal function unit which has the transmission/reception functions of a radio terminal. A radio signal is transmitted from the terminal function unit to the signal processing unit of an access point through the antenna of the access point, and a process for the calling connection between the terminal function unit and a test server is executed through the antenna of the access point, and the antenna and signal processing unit of the access point (along a path). The normalities of the antenna of the access point and the access point, or the abnormality of any of them is judged in accordance with the success or failure of the calling connection.
