Cross-System Radio Channel Coordination to Suppress Base Station Interference
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods fail to effectively suppress interference between wireless communication systems operated by different operating agencies, particularly in scenarios where a wireless base station is relocated, leading to decreased communication throughput.
Innovation Solution
A communication apparatus and management apparatus are employed to detect signals from different wireless communication systems, sharing information about detected signals to manage and adjust radio channels, allowing base stations to use non-overlapping channels to minimize interference.

If base stations are relocated to match traffic occurrence locations, then communication service coverage is improved, but inter-area interference increases due to overlapping frequency channels
Solution Approach 1:
A control apparatus acts as an intermediary between base stations of different wireless communication systems. When the control apparatus detects that a base station in one system is using a frequency channel that overlaps with a base station in another system, it mediates by notifying the other system's management apparatus to change the frequency channel, thereby suppressing inter-area interference while maintaining service coverage
Solution Approach 2:
The control apparatus continuously monitors frequency channel usage across different wireless communication systems and provides feedback when overlapping is detected. This feedback mechanism enables dynamic adjustment of frequency channels to prevent interference, allowing base stations to be relocated without causing harmful interactions between systems
2Object-affected harmful factors
If frequency channels are changed to suppress interference, then inter-area interference is reduced, but communication throughput decreases due to channel reconfiguration
Solution Approach 1:
The control apparatus performs preliminary detection of frequency channel overlaps before they cause significant interference. By proactively identifying and resolving channel conflicts, the system minimizes the need for frequent channel reconfigurations, thereby maintaining communication throughput while preventing interference
Solution Approach 2:
The system dynamically adjusts frequency channels only when necessary, based on real-time detection of overlapping usage. This dynamic approach allows the system to maintain stable channel assignments for most operations (preserving throughput) while enabling rapid channel changes when interference is detected (suppressing harmful factors)
3Object-affected harmful factors
If manual mediation is performed to suppress interference, then frequency channel conflicts are resolved, but operational complexity increases requiring direct operator intervention
Solution Approach 1:
The control apparatus automatically detects frequency channel overlaps and initiates resolution procedures without requiring manual operator intervention. The system self-services by monitoring its own environment, identifying conflicts, and coordinating with other systems to resolve interference, thereby reducing operational complexity while maintaining effective conflict resolution

AI summary
A communication apparatus detects a signal transmitted from a first base station in another wireless communication system that is different from a wireless communication system to which the communication apparatus belongs, and transmits first information and second information to a management apparatus that manages communication in the other wireless communication system, the first information being related to the first base station, the second information indicating a radio channel to be used in a case where communication involving user data is performed with a second base station belonging to the wireless communication system when the communication apparatus has detected the signal.
