Cloud Processing Architecture for Mobile Network Resource Sharing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current mobile communications networks face inefficiencies due to a 1-to-1 relationship between baseband and RF hardware deployments, leading to underutilization of resources, especially during off-peak hours, and high costs associated with dedicated links for BTS hoteling architectures.
Innovation Solution
Implementing a cloud processing architecture that allows for ad-hoc sharing of non-dedicated processing resources between radio heads, utilizing existing public switched telephone networks for radio head links, and integrating active antennas with absolute timing references to manage signal processing and synchronization, thereby reducing the need for dedicated links and optimizing resource allocation based on demand.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a 1-to-1 relationship between baseband and RF hardware is maintained, then each BTS site can fully support peak hour traffic capacity, but resource utilization during off-peak hours becomes inefficient and costs increase
Solution Approach 1:
Multiple BTS sites are merged into a centralized BTS hotel where baseband processing units are physically co-located. This allows resources to be shared across multiple sites rather than being dedicated to each site individually, enabling efficient resource utilization during off-peak hours while maintaining peak capacity support through pooled processing power.
Solution Approach 2:
The system implements dynamic resource allocation where processing capacity can be dynamically adjusted based on traffic demand. During peak hours, more processing resources are allocated to handle high traffic volumes, while during off-peak hours, resources are reduced or reallocated to other sites, optimizing both reliability and productivity across different time periods.
2Reliability
If dedicated fibre-optic or microwave links are used to connect BTS hotel and remote radio heads, then reliable communication is achieved, but capital and operational expenditures increase
Solution Approach 1:
The system uses existing public switched telephone networks for communication between BTS hotel and remote radio heads, making the communication infrastructure universal and multi-functional. Instead of dedicating专用 links for each connection, the same network infrastructure serves multiple purposes, reducing capital expenditure on installation and operational costs while maintaining communication reliability.
3Ease of manufacture
If BTS Hoteling architecture is implemented to reduce costs, then housing and maintenance costs are reduced, but transmission delays may increase
Solution Approach 1:
The system incorporates feedback mechanisms that monitor transmission quality and delay in real-time. Based on this feedback, the system can dynamically adjust processing parameters, prioritize critical traffic, and optimize routing to minimize transmission delays while maintaining the cost benefits of centralized housing and maintenance.
