Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In heterogeneous wireless communication systems, the complexity of radio environments due to mixed networks like CSG cells, hybrid cells, and WLANs leads to inefficiencies in UE operations and resource utilization, making it difficult to maintain optimal service quality and maximize radio resource efficiency.
Innovation Solution

Engineering Contradiction Analysis
1Adaptability or versatility
If heterogeneous networks (CSG cells, hybrid cells, WLANs) are introduced for traffic offloading and service differentiation, then service quality and traffic handling capability are improved, but radio environment complexity increases and UE measurement/mobility operations fail
Solution Approach 1:
The patent segments the heterogeneous network environment into distinct network types (CSG, hybrid, WLAN, etc.) and creates separate measurement configurations and logging mechanisms for each type. This segmentation allows the system to handle each network type's specific characteristics independently, reducing the overall complexity of managing the heterogeneous environment while maintaining comprehensive service quality across all network types.
2Productivity
If heterogeneous networks are introduced for traffic offloading, then traffic handling capability is improved, but radio resource utilization efficiency deteriorates
Solution Approach 1:
The patent implements feedback mechanisms where UE logs measurement results and network configuration information from heterogeneous networks, then reports this logged information back to the network. This feedback loop enables the network to optimize resource allocation and configuration based on actual UE experiences in different heterogeneous network environments, improving radio resource utilization efficiency while maintaining enhanced traffic handling capability.
3Reliability
If comprehensive heterogeneous network information is logged and reported, then network optimization capability is improved, but signaling overhead and processing complexity increase
Solution Approach 1:
The patent employs preliminary action by having UE log measurement information and network configuration details during idle periods and normal operation, storing this data locally before any optimization analysis is needed. This preliminary logging of comprehensive heterogeneous network information ensures that when network optimization is required, the data is already prepared and organized, reducing the complexity of real-time signaling processing while maintaining high network optimization capability.
