Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional communication networks face challenges in efficiently managing network resources due to unpredictable user mobility and varying usage patterns, leading to suboptimal resource allocation and increased costs, as they struggle to provide adequate coverage without wasting resources or frustrating users.
Innovation Solution
The implementation of a dynamic virtual distributed antenna system using software-defined radio (SDR) technology, which allows for the dynamic allocation of network resources across multiple sectors and digital remote units, enabling flexible resource management and optimization based on geographic and temporal usage patterns without modifying the physical architecture.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional communication networks use fixed physical architecture for resource allocation, then network infrastructure stability is maintained, but resource allocation efficiency deteriorates due to inability to adapt to unpredictable user mobility and varying usage patterns
Solution Approach 1:
The patent implements dynamic resource allocation by allowing Digital Remote Units (DRUs) to be reassigned between sectors based on real-time traffic conditions. The system transitions from static physical architecture to dynamic virtual allocation, where DRUs can be flexibly assigned to different sectors as users move or usage patterns change, thereby improving resource allocation efficiency without requiring physical reconfiguration of the network infrastructure.
2Reliability
If network resources are statically allocated to fixed geographic areas, then infrastructure simplicity is maintained, but network coverage effectiveness deteriorates due to unpredictable user mobility patterns
Solution Approach 1:
The system changes the allocation parameters dynamically by adjusting which DRUs serve which sectors based on traffic conditions and user mobility patterns. Instead of fixed geographic boundaries, the patent uses flexible parameter-based allocation where the same physical DRU can serve different virtual sectors at different times, improving network coverage effectiveness while maintaining infrastructure simplicity.
3Productivity
If distributed antenna systems use fixed sector assignments for Digital Remote Units, then system stability is maintained, but resource utilization deteriorates due to inability to balance traffic loads dynamically
Solution Approach 1:
The patent implements dynamic sector assignments where DRUs can be reassigned between sectors based on real-time traffic conditions. This allows the system to balance traffic loads effectively - when one sector becomes congested, DRUs can be dynamically transferred to less utilized sectors, improving overall resource utilization while maintaining system stability through controlled, managed transitions.
4Reliability
If communication networks deploy additional physical infrastructure to handle peak demand in all areas, then service availability is improved, but cost efficiency deteriorates due to resource waste in low-usage areas
Solution Approach 1:
The patent makes DRUs universal by enabling them to serve multiple different sectors at different times. Instead of deploying dedicated infrastructure for each potential high-demand area, the same physical DRUs can be dynamically assigned to different sectors as needed, providing service availability in multiple locations without the resource waste of static, dedicated infrastructure in each area.
