RAN Slice Manager for Network Resource Isolation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current technologies face challenges in implementing network slicing in Radio Access Networks (RAN) due to issues with dynamic channel quality, transmission isolation over common broadcast mediums, and interaction with Core Networks, limiting the effectiveness of RAN slicing in mobile wireless networks.
Innovation Solution
The method involves allocating unique sets of network resources to each service in the RAN, using a RAN slice manager to select transmission parameters such as radio frequency, time resources, and numerology for each service, enabling efficient resource utilization and isolation between different services.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If network slicing is implemented in RAN using common broadcast transmission medium, then resource utilization efficiency is improved, but transmission isolation between services deteriorates
Solution Approach 1:
The patent segments the common RAN resources into multiple virtual network slices, each dedicated to specific services. The RAN slice manager divides radio resources, time resources, and frequency resources into isolated segments for different slices, enabling both efficient utilization and strict isolation simultaneously.
Solution Approach 2:
The RAN slice manager acts as an intermediary between the common RAN resources and multiple services. It mediates resource allocation by receiving service requirements, determining appropriate slice assignments, and configuring transmission parameters to ensure both efficient resource use and proper isolation.
2Adaptability or versatility
If dynamic channel quality is accommodated in RAN slicing, then service adaptability is improved, but system complexity increases
Solution Approach 1:
The patent implements dynamic resource allocation within network slices to adapt to changing channel conditions. The RAN slice manager continuously monitors service requirements and channel quality, dynamically adjusting resource allocation and transmission parameters while maintaining slice isolation, thus achieving adaptability without permanent complexity increase.
Solution Approach 2:
The system changes transmission parameters (power, modulation, coding) within each slice based on dynamic channel conditions. The RAN slice manager adjusts these parameters per-slice to accommodate varying service requirements and channel quality, enabling adaptability through parameter optimization rather than structural complexity.
3Ease of manufacture
If RAN slicing is implemented with static resource pool, then implementation simplicity is improved, but service customization capability deteriorates
Solution Approach 1:
The patent creates a universal RAN slice manager that can serve multiple different services through a single implementation. The same RAN slice manager handles diverse service types (eMBB, URLLC, mMTC) by applying different slicing configurations, achieving service customization without requiring separate specialized systems for each service type.
Solution Approach 2:
The system performs preliminary slice configuration and resource allocation decisions before actual service deployment. The RAN slice manager pre-establishes slice templates and resource allocation patterns that can be quickly instantiated for different services, simplifying implementation while maintaining customization capability through pre-configured flexibility.
