Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication networks face challenges in coordinating seamless handovers and efficient spectrum sharing between different wireless communication networks, particularly when UE devices roam across networks with varying architectures and shared RF spectra, leading to potential interference and suboptimal service quality.
Innovation Solution
Implementing a method where base stations from different wireless communication networks establish direct communication interfaces to coordinate handovers and share common RF spectrum, using dedicated or logical interfaces to facilitate low-latency communication, optimize spectrum use, and prevent interference, based on load and market conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If base stations of different wireless communication networks operate independently without direct communication, then each network maintains its own architecture and operation simplicity, but handover coordination between networks becomes difficult and service continuity is compromised
Solution Approach 1:
The patent introduces a communication interface as an intermediary mechanism between base stations of different wireless communication networks. This interface enables direct communication and coordination for handover procedures, allowing base stations to exchange necessary information while maintaining their respective network architectures. The intermediary interface resolves the contradiction by providing a standardized communication path without requiring fundamental changes to either network's core architecture.
2Ease of operation
If base stations establish direct communication interfaces to coordinate handovers, then handover coordination improves and service continuity is ensured, but the complexity of implementing and maintaining these interfaces increases
Solution Approach 1:
The communication interface is designed with universal functionality to handle multiple aspects of inter-network coordination, including handover signaling, spectrum sharing agreements, and interference coordination. By creating a multi-functional interface that can handle various coordination tasks through standardized procedures, the patent reduces the overall complexity compared to implementing separate dedicated mechanisms for each function.
Solution Approach 2:
The interface implementation allows for parameter adjustments and configurations to optimize performance while managing complexity. Communication protocols and interface parameters can be modified to balance coordination capabilities with implementation complexity, enabling networks to adapt the interface complexity to their specific operational requirements.
3Productivity
If networks share common RF spectrum without coordination, then spectrum utilization increases, but interference between networks occurs and service quality deteriorates
Solution Approach 1:
The communication interface establishes a feedback mechanism between base stations of different networks that share common RF spectrum. Through this interface, base stations can monitor and report interference conditions, exchange spectrum usage information, and coordinate their transmissions dynamically. This feedback loop enables networks to maintain high spectrum utilization while actively managing and reducing interference through coordinated resource allocation and power control.
