Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Satellite communication systems face challenges with rigid and static coverage areas, leading to overloading and signal degradation due to uneven user demand, which results in degraded service quality and inability to dynamically adjust coverage or redistribute load in real-time.
Innovation Solution
A dynamic beam management system for extraterrestrial base stations that adapts coverage areas based on real-time demand and load metrics, using inter-satellite communication to predict and adjust coverage overlaps, ensuring efficient and responsive communication by redistributing load between satellites.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If coverage areas of extraterrestrial base stations are kept static and rigid, then system simplicity is maintained, but overloading occurs due to uneven user demand distribution
Solution Approach 1:
The patent implements dynamic coverage area adjustment where extraterrestrial base stations can modify their coverage boundaries in real-time based on load conditions. The anchor base station determines optimized coverage areas that dynamically adapt to user demand distribution, preventing overloading by redistributing users to underloaded stations within the dynamic coverage zones.
Solution Approach 2:
The system changes the coverage area parameters of extraterrestrial base stations based on load metrics. The anchor base station calculates optimized coverage areas by adjusting spatial parameters dynamically, allowing the system to respond to changing user demand patterns and prevent overloading conditions.
2Reliability
If coverage areas are dynamically adjusted to prevent overloading, then service quality is improved, but system complexity increases
Solution Approach 1:
The system enables extraterrestrial base stations to autonomously determine their own optimized coverage areas based on load information received from the anchor base station. Each base station independently adjusts its coverage parameters without requiring complex centralized control, reducing overall system complexity while maintaining dynamic adaptation capabilities.
Solution Approach 2:
The anchor base station receives load information from all extraterrestrial base stations and uses this feedback to calculate optimized coverage areas. This feedback loop enables the system to continuously adapt coverage boundaries based on actual load conditions, improving service quality while maintaining manageable complexity through distributed information gathering.
3Reliability
If load is redistributed between extraterrestrial base stations, then overloading is prevented, but inter-satellite communication requirements increase system complexity
Solution Approach 1:
The anchor extraterrestrial base station serves as an intermediary that coordinates load redistribution among all base stations. Instead of requiring direct complex communication between all pairs of base stations, the anchor station receives load information from all stations, calculates optimized coverage areas, and distributes the optimized parameters back to individual stations, simplifying the overall communication architecture.

AI summary
Embodiments of the present disclosure are directed to systems and methods for improved management of extraterrestrial base stations' coverage areas. The system comprises one or more extraterrestrial base stations of a radio access network and one or more computer processing components. The disclosure involves continuously monitoring signal metrics or load levels from multiple base station coverage areas. Upon detection that a particular metric or load level surpasses a preset threshold, devices in overlapping coverage zones between multiple base stations are identified. Specific devices may then be directed to attach to an alternate base station.
