Maritime Base Station Power Control for Vessel Interference
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Maritime vessels face challenges in efficient and cost-effective communication due to interference among base stations, loss of satellite connectivity, and lack of integration with nearby vessels, leading to unreliable radio communication and limited high-speed services.
Innovation Solution
Implement an interference self-controlling mechanism that determines the contribution value of each base station to the network, allowing for power reduction or power off when interference is severe, using positioning, network configuration, and connection status information to optimize communication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If base stations operate at full power to maintain communication coverage, then communication coverage is improved, but network interference increases
Solution Approach 1:
The patent implements dynamic power adjustment for base stations based on real-time network conditions. The server determines contribution values for each base station and dynamically adjusts transmit power levels, allowing base stations to operate at full power when needed for coverage while reducing power when interference becomes problematic, thus resolving the contradiction between maintaining coverage and reducing interference
Solution Approach 2:
The system changes the power parameter of base stations based on network conditions and contribution values. By adjusting the transmit power parameter dynamically rather than operating at fixed full power, the system can maintain adequate coverage while reducing interference in specific scenarios where base stations are causing harmful effects to other maritime vessels
2Reliability
If all base stations operate simultaneously to ensure network availability, then network availability is improved, but interference between base stations increases
Solution Approach 1:
The patent implements a feedback mechanism where maritime vessels report received signal strength and interference levels to a server. The server calculates contribution values based on this feedback and determines optimal power adjustment decisions. This feedback loop allows the system to maintain network availability while dynamically responding to interference conditions, resolving the contradiction between simultaneous operation and interference reduction
Solution Approach 2:
Each base station autonomously adjusts its own power level based on contribution value determination by the server. The system enables self-service operation where base stations can independently modify their transmission parameters to reduce interference while maintaining their contribution to network availability, eliminating the need for complete system shutdown or coordinated cessation of operations
3Object-generated harmful factors
If base station power is reduced to minimize interference, then network interference is reduced, but communication coverage deteriorates
Solution Approach 1:
The patent applies local quality adjustment by determining individual contribution values for each base station based on its specific location, maritime vessels in proximity, and local interference conditions. Rather than uniformly reducing power across all base stations, the system selectively adjusts power levels locally at each base station, minimizing interference in affected areas while preserving coverage in areas where the base station provides unique service
Solution Approach 2:
The system dynamically adjusts power levels based on real-time contribution value assessment. When a base station's contribution value indicates it is causing more interference than benefit, power is reduced locally. When the base station provides critical coverage with minimal interference impact, power is maintained. This dynamic local adjustment resolves the contradiction between reducing interference and maintaining coverage

AI summary
Methods and apparatuses are disclosed for maritime communication. According to an embodiment, a network comprises a first server and a first base station at a first maritime vessel, and one or more second servers and one or more second base stations at one or more respective second maritime vessels. In response to a trigger event indicating that interference between at least two base stations of the first base station and the one or more second base stations is serious, the first server obtains a contribution value of the first base station to the network determined by the second server. The first server determines whether the first base station needs power reduction or power off based at least on the obtained contribution value. When determining that the first base station needs power reduction or power off, the first server sends an instruction for power reduction or power off to the first base station.
