Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The discontinuous signal coverage of satellite networks due to the limited number of communication satellites and varying coverage with satellite movement poses challenges in maintaining consistent wireless communication quality.
Innovation Solution
A base station sends measurement configuration signaling to a multi-mode terminal, which measures the satellite network based on the configuration information, allowing the base station to adjust signal coverage by controlling satellite transmission power, trajectory, and antenna direction based on the measurement results.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the number of communication satellites is kept small, then device complexity and cost are reduced, but signal coverage becomes discontinuous and varies with satellite movement
Solution Approach 1:
The patent implements dynamic measurement configuration where the base station continuously monitors satellite signal quality and adjusts measurement parameters based on real-time conditions. The terminal adapts its measurement behavior according to satellite movement and signal strength changes, allowing the system to maintain reliable coverage with fewer satellites by optimizing their utilization dynamically
Solution Approach 2:
The patent establishes a feedback mechanism where measurement results from the terminal are reported to the base station, which then adjusts satellite network parameters accordingly. This closed-loop control enables the system to compensate for discontinuous coverage by dynamically adjusting satellite beam directions, transmission power, or terminal handover decisions based on real-time measurement feedback
2Area of stationary object
If satellite movement is allowed for coverage optimization, then signal coverage area is improved, but coverage consistency deteriorates due to varying positions
Solution Approach 1:
The patent configures the terminal to perform measurements in advance according to pre-defined measurement configurations provided by the base station. The base station predicts satellite positions and pre-configures measurement parameters, allowing the terminal to prepare measurements before satellite movement occurs, thus maintaining coverage consistency through proactive adaptation
Solution Approach 2:
The patent changes measurement parameters dynamically based on satellite position and signal conditions. The base station adjusts measurement bandwidth, reference signal configurations, and reporting thresholds according to real-time satellite trajectories, allowing the system to maintain consistent coverage quality despite satellite movement by adapting parameters to compensate for position changes
