Secondary Cell Handover Optimization for Reduced Power Consumption
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication systems face challenges in achieving seamless handover of User Equipment (UE) between cells, particularly due to limited channel capacity for system information transmission, which affects network service quality and increases power consumption.
Innovation Solution
The solution involves forming a secondary cell with fewer channels for transmitting system information, allowing it to provide network services to a target UE with high data traffic demands. This configuration reduces the likelihood of UE handover between cells while optimizing data transmission capabilities and power consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a secondary cell with fewer channels for transmitting system information is formed, then data transmission capability is improved and power consumption is reduced, but the ability to provide complete system information to UEs is compromised
Solution Approach 1:
The patent divides cell functions into primary and secondary roles. The primary cell provides complete system information, while the secondary cell focuses on data transmission with reduced system information channels. This segmentation allows each cell type to optimize its specific function without compromise.
Solution Approach 2:
The secondary cell serves multiple purposes: it provides data transmission capabilities while also maintaining basic connectivity for UEs. By reducing system information channels, it frees up resources for data transmission while still fulfilling essential communication functions.
2Reliability
If UE performs handover between cells to meet high data traffic demands, then network service quality is improved, but handover complexity and service interruption increase
Solution Approach 1:
The patent dynamically adjusts the role of cells based on traffic conditions. When a secondary cell has sufficient capacity, it can accept UEs without requiring handover from the primary cell. This dynamic allocation reduces handover operations while maintaining service quality.
Solution Approach 2:
The secondary cell acts as an intermediary for UEs with high data traffic demands. Instead of requiring handover to a different cell, UEs can remain connected to the primary cell for control functions while utilizing the secondary cell for data transmission, mediated through network coordination.
3Use of energy by moving object
If the number of channels for transmitting system information in a secondary cell is reduced, then power consumption is reduced and data transmission capacity is increased, but the ease of UE access to system information is compromised
Solution Approach 1:
The patent applies different channel configurations to different cell types. Primary cells maintain full system information channels for ease of access, while secondary cells use reduced channels optimized for their specific role. This local differentiation allows each cell type to optimize its characteristics for its intended function.
