Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional resource management systems in non-terrestrial networks, such as satellite communications, struggle with inefficient allocation of resources due to static power and bandwidth settings, leading to increased energy consumption, network congestion, and reduced scalability, which affects network performance and contributes to greenhouse gas emissions.
Innovation Solution
A dynamic resource management system for satellites that adjusts transmission power and bandwidth based on the presence or absence of Radio Resource Control (RRC) connections, using reduced power and bandwidth when no connections are present to conserve energy and resources.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If static power and bandwidth settings are used in conventional resource management systems, then system simplicity is maintained, but energy consumption increases and resource allocation efficiency deteriorates
Solution Approach 1:
The patent implements dynamic resource management by adjusting transmission power and bandwidth allocation in real-time based on the presence of RRC connections. The system transitions from static to dynamic configuration, where power and bandwidth settings are continuously adapted according to network conditions and user connection status, thereby reducing energy consumption while maintaining operational simplicity through automated control mechanisms
2Stability of the object's composition
If static power and bandwidth settings are used, then system stability is maintained, but network congestion increases and scalability deteriorates
Solution Approach 1:
The system dynamically adjusts power and bandwidth allocation based on real-time detection of RRC connections. When connections are present, the system allocates sufficient resources to maintain quality of service; when connections are absent, the system reduces resource allocation to prevent congestion. This dynamic adaptation enables the network to scale efficiently while maintaining stability through automated resource management
3Reliability
If full power and bandwidth are always transmitted, then coverage and signal reliability are improved, but energy consumption and resource waste increase
Solution Approach 1:
The patent changes transmission parameters (power and bandwidth) based on the presence or absence of RRC connections. When no connections are detected, the system reduces power and bandwidth to minimum necessary levels, conserving energy while maintaining coverage capability. When connections are present, the system increases power and bandwidth allocation to ensure reliable signal transmission, thus optimizing the balance between reliability and energy efficiency
4Device complexity
If conventional resource allocation is used, then system simplicity is maintained, but greenhouse gas emissions increase due to inefficient resource utilization
Solution Approach 1:
The system implements feedback-based resource management by continuously monitoring RRC connection status and adjusting power and bandwidth allocation accordingly. This feedback mechanism enables real-time optimization of resource utilization, reducing energy consumption and associated greenhouse gas emissions while maintaining operational simplicity through automated control loops that respond to network conditions
Data Source
AI summary
The technology is directed to a system that allocates a frequency band to a satellite within a non-terrestrial network (NTN) and determines the available channel bandwidth for data transmissions within that frequency band. If the satellite detects an absence of a Radio Resource Control (RRC) connection between the satellite and at least one terminal device within the geographical location, which indicates a lack of active communication with the terminal devices, the satellite responds by transmitting signals at a reduced transmit power and within a portion of the available channel bandwidth towards the geographical location. The RRC connection can be managed by an RRC protocol.
