Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication networks, particularly in the transition from 4G to 5G, face challenges in managing heterogeneous network architectures and diverse applications, requiring more efficient control of wireless resources to support various traffic types and user equipment with different communication and computation capabilities.
Innovation Solution
The implementation of network slicing, specifically vertical and horizontal slicing, allows for the logical partitioning of radio access networks to create programmable, scalable, and flexible slices tailored to specific use-cases, enabling efficient resource allocation and management across the wireless network.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If network slicing is implemented to support diverse applications and traffic types, then adaptability and service diversity are improved, but device complexity and network configuration complexity increase
Solution Approach 1:
The network is divided into multiple independent network slices, each optimized for specific services or applications. This segmentation allows diverse services to run on dedicated logical networks while sharing physical infrastructure, thereby improving service diversity without proportionally increasing overall network complexity.
Solution Approach 2:
A single physical network infrastructure is designed to support multiple network slices simultaneously, each serving different functions. This multi-functionality approach allows the same hardware resources to be universally utilized across different service types, improving adaptability while avoiding the need for separate dedicated networks for each service.
2Productivity
If network slicing is implemented to optimize resource allocation for specific use-cases, then resource usage efficiency is improved, but device complexity and management overhead increase
Solution Approach 1:
Network slicing enables dynamic resource allocation where resources can be flexibly assigned and reassigned to different slices based on real-time service requirements and traffic patterns. This dynamic management optimizes resource usage efficiency by ensuring resources are allocated to where they are most needed rather than being statically assigned.
Solution Approach 2:
A network slice manager or control plane acts as an intermediary that handles the complex tasks of slice creation, resource allocation, and management. This intermediary abstracts the complexity from individual network elements, centralizing management functions and reducing the burden on distributed network components while maintaining efficient resource allocation.
