Base Station Handover Using Renewable Energy Use Rate
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current communication systems do not effectively increase the use rate of renewable energy, as communication control is not optimized to utilize renewable energy sources efficiently across base stations.
Innovation Solution
A communication system and method where base stations exchange handover requests and responses, including renewable energy use rates, to determine optimal data transmission rates based on the renewable energy availability of target base stations, allowing user terminals to switch and adjust data transmission accordingly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If communication control is performed regardless of renewable energy usage, then communication operations can be maintained without interruption, but the renewable energy use rate of the entire communication system cannot be increased
Solution Approach 1:
The target base station transmits its renewable energy use rate to the source base station in advance (in the handover response message) before the handover is executed. This allows the source base station to have the information ready when making the handover decision, enabling proactive optimization of renewable energy usage without adding complex real-time monitoring systems.
Solution Approach 2:
The handover response message includes feedback information about the target base station's renewable energy use rate. This feedback mechanism enables the source base station to make informed handover decisions based on the energy characteristics of potential target stations, thereby optimizing the overall renewable energy utilization of the communication system.
2Loss of energy
If handover decisions are made based on renewable energy use rate, then the renewable energy use rate of the communication system can be increased, but the handover decision-making process becomes more complex
Solution Approach 1:
The existing handover response message format is utilized to carry both traditional handover parameters and the renewable energy use rate information. This multi-functional use of existing message structures allows energy-optimized handover decisions without requiring separate dedicated signaling channels or additional complex message formats.
Solution Approach 2:
The handover decision criteria are extended to include the renewable energy use rate as an additional parameter. By incorporating this parameter into the existing handover evaluation framework, the system can optimize energy usage while maintaining compatibility with current handover procedures and minimizing operational complexity.
3Productivity
If base stations exchange renewable energy use rate information, then optimal data transmission rates can be determined, but the signaling overhead increases
Solution Approach 1:
The renewable energy use rate information is merged into the existing handover response message structure. By combining this energy-related information with the standard handover signaling, the patent transmits necessary data without requiring separate dedicated signaling messages, thereby minimizing additional signaling overhead while enabling efficient data transmission decisions.
