UAV Movement Adjustment for Radio Network Load Balancing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Unmanned aerial vehicles (UAVs) and other wireless transceivers experience difficulties in maintaining service quality while transmitting high-definition video due to high cell loads in wireless communication networks, leading to degraded radio network performance and limited capacity, especially when multiple devices pass through the same cell.
Innovation Solution
A movement adjustment device that analyzes radio network condition data to adjust the path of wireless transceivers, optimizing their route to avoid heavily loaded cells and ensure service requirements are met by changing cell paths or speeds, thereby reducing the load on individual cells and maintaining network performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If multiple wireless transceivers transmit high-definition video through the same cell, then the network capacity is depleted, but the service requirement fulfillment deteriorates
Solution Approach 1:
The patent implements dynamic route adjustment by continuously monitoring radio network condition data and modifying the planned movement of wireless transceivers in real-time. The movement adjustment device dynamically changes the route or speed based on current cell load conditions, transforming the static routing into a dynamic adaptation process that responds to network capacity variations.
Solution Approach 2:
The system changes the parameter of transceiver movement (route or speed) in response to changing network conditions. By adjusting movement parameters based on cell load measurements, the system optimizes the distribution of traffic across the network, preventing capacity depletion while maintaining service requirements.
2Ease of operation
If a wireless transceiver passes through a highly loaded cell, then the transceiver can access the network, but the video quality and radio network performance deteriorate
Solution Approach 1:
The movement adjustment device acts as an intermediary between the wireless transceiver and the radio network. It monitors network condition data and intermediates the transceiver's movement by adjusting routes or speeds to avoid highly loaded cells, thereby protecting video quality while maintaining network access capability.
Solution Approach 2:
The system performs preliminary analysis of radio network condition data before the transceiver enters a cell. By evaluating cell load conditions in advance and adjusting the movement plan beforehand, the system prevents video quality deterioration rather than reacting after the problem occurs.
3Productivity
If the transceiver follows the planned route, then the mission objective is achieved, but the network load increases and performance suffers
Solution Approach 1:
The system modifies the movement parameters (route or speed) of the transceiver based on network load conditions. By dynamically adjusting these parameters, the system reduces the harmful network load generated by the transceiver while ensuring the mission is still completed, thereby resolving the contradiction between productivity and harmful effects.
Solution Approach 2:
The movement adjustment device implements a feedback mechanism by continuously obtaining radio network condition data and using this information to adjust the transceiver's movement. This closed-loop control allows the system to respond to network load changes and optimize the balance between mission completion and network load reduction.
