Base Station Overload Relay Handoff
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The increasing number of IoT terminals leads to high load conditions in base stations and radio relay stations, causing communication unavailability due to limited communication resources.
Innovation Solution
A base station equipped with a control unit to detect overload conditions and transmit information to a radio relay station to connect with another base station not in overload, allowing the relay station to switch connections and alleviate the load.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If the base station communicates with a large number of IoT terminals directly, then the coverage area is maintained, but the base station enters overload condition causing communication unavailability
Solution Approach 1:
The patent divides the communication load by introducing relay stations that act as intermediate nodes between the base station and IoT terminals. This segments the direct communication path into two parts: base station to relay station, and relay station to IoT terminals. The base station only needs to communicate with relay stations rather than all IoT terminals directly, reducing its communication burden and preventing overload while maintaining coverage for large numbers of terminals.
2Area of stationary object
If the base station serves more communication terminals through relay stations, then the communication coverage is extended, but the base station load increases beyond capacity
Solution Approach 1:
The patent introduces relay stations as intermediary nodes between the base station and IoT terminals. These relay stations receive communication signals from the base station and forward them to IoT terminals, and vice versa. This intermediary structure allows the base station to extend communication coverage to more terminals without directly handling all communications, thus preventing base station overload while maintaining expanded coverage.
3Ease of operation
If the relay station connects to the base station during overload condition, then the relay function is maintained, but communication resources are insufficient causing unavailability
Solution Approach 1:
The patent implements dynamic connection management where relay stations can switch between different base stations based on load conditions. When a base station is in overload condition, connected relay stations can be instructed to disconnect and reconnect to alternative base stations with available capacity. This dynamic adaptation ensures that relay functions continue without interruption while avoiding communication unavailability caused by resource exhaustion at overloaded base stations.

AI summary
The present disclosure aims to provide a base station, a radio relay station, a communication method, and a program capable of preventing communication from being unavailable when the base station is brought into a high load condition. A base station (10) configured to communicate with a communication terminal (30) through a radio relay station (20), the base station (10) including: a control unit (11) configured to detect whether the own apparatus is in an overload condition exceeding a predetermined load; and a communication unit (12) configured to transmit, in order to cause the radio relay station (20) to connect to another base station that is not in an overload condition, information about the other base station to the radio relay station (20) when the control unit (11) detects that the own apparatus is in an overload condition.
