Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wireless communication systems face challenges in optimizing radio resource assignments among competing radio access services due to differences in radio access technologies, leading to inefficient spectrum utilization and interference.
Innovation Solution
Implementing an Authorized Shared Access (ASA) system that uses a controller to identify compatible radio access networks and optimize resource assignments based on capability information supplied by radio access nodes, allowing for dynamic allocation of shared radio resources while minimizing interference.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional spectrum access methods are used without considering radio access network compatibility, then spectrum allocation is simpler and faster, but interference increases and spectrum utilization efficiency deteriorates
Solution Approach 1:
The patent introduces a spectrum access server as an intermediary between radio access networks and spectrum resources. This server collects capability information from different radio access networks, estimates compatibility between them, and makes informed spectrum allocation decisions. The intermediary handles the complexity of compatibility assessment, allowing simple spectrum allocation decisions while improving utilization efficiency through compatibility-aware resource assignment.
2Productivity
If spectrum resources are shared among multiple radio access services without compatibility consideration, then spectrum utilization increases, but interference between different radio access technologies worsens
Solution Approach 1:
The patent changes the allocation parameters from simple spectrum resource assignment to compatibility-based resource assignment. By incorporating capability information and compatibility estimates as additional parameters in the allocation decision, the system can share spectrum resources among multiple radio access services while avoiding harmful interference through intelligent compatibility assessment.
3Reliability
If radio resource assignments are optimized based on compatibility information from multiple radio access networks, then interference is reduced and reliability improves, but the complexity of resource management increases
Solution Approach 1:
The patent implements a self-service mechanism where radio access networks automatically provide their capability information to the spectrum access server. The server autonomously processes this information, estimates compatibility between networks, and performs resource allocation without requiring complex manual configuration or coordination between networks. This self-service approach reduces management complexity while improving reliability through compatibility-aware allocation.
