Relay Station Abnormality Detection via Neighbor Base Station Inquiry
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In areas where radio waves have difficulty reaching, such as commercial facilities or mountainous regions, existing communication systems struggle to detect abnormalities in relay stations promptly, leading to potential communication disruptions.
Innovation Solution
A communication system where the relay station notifies the destination base station of neighboring base stations capable of wireless communication, allowing the base station to inquire about connectivity and adjust transmission output when disconnection occurs, thereby determining abnormality and maintaining communication stability.

1Area of stationary object
If relay stations are installed in areas where radio waves have difficulty reaching, then communication coverage is improved, but the ability to detect abnormalities in relay stations deteriorates
Solution Approach 1:
The relay station is configured to notify the base station in advance of neighboring base stations that can perform wireless communication with the relay station. This preliminary information is stored and used when abnormality occurs, enabling rapid detection without waiting for actual failure symptoms to manifest fully.
Solution Approach 2:
Neighboring base stations serve as intermediary nodes to detect relay station abnormalities. When the primary base station cannot directly detect relay station failure, it queries neighboring base stations that can communicate with the relay station, using them as mediators to confirm whether the relay station is still operational.
2Reliability
If the base station increases transmission output to maintain communication, then communication stability is improved, but energy consumption increases
Solution Approach 1:
The transmission output is dynamically adjusted based on the operational status of the relay station and neighboring base stations. When relay station abnormality is detected, the base station increases transmission output to maintain communication stability. When the relay station is normal, the base station uses standard transmission levels, optimizing energy consumption.
Solution Approach 2:
The transmission output parameter is changed conditionally based on relay station status. The base station monitors relay station health and adjusts the transmission power parameter accordingly - increasing it when abnormalities are detected and maintaining or reducing it when the relay station operates normally, thus balancing communication stability with energy efficiency.

AI summary
A communication system includes a destination base station that performs wireless communication with a terminal and is a communication destination; a neighboring base station; and a relay station that relays the wireless communication between the terminal and the destination base station. The relay station notifies the destination base station of information on the neighboring base station capable of communicating wirelessly with the relay station, as neighboring base station information, wherein when wireless communication between the destination base station and the relay station is disconnected, the destination base station makes an inquiry to the neighboring base station with reference to the neighboring base station information, and wherein the destination base station determines that abnormality has occurred in the relay station when wireless communication between the relay station and the neighboring base station is not confirmed.
