Multi-Operator Wireless Base Station Resource Sharing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The increasing demand for network capacity due to the advent of smartphones complicates providing reliable and ubiquitous wireless coverage, as traditional solutions like adding base stations are costly and impractical in high infrastructure density areas, and public acceptance of wireless equipment is limited.
Innovation Solution
A wireless Base Station system that allows multiple operators to share system resources by dynamically allocating wireless Access Spectrum and creating multiple Radio Access Networks, enabling efficient communication with multiple Core Network data sources and Subscriber Stations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If additional Base Stations are added to increase network capacity, then network capacity is improved, but capital and operational costs increase significantly
Solution Approach 1:
Multiple operators share a single physical base station infrastructure through virtualization, combining their network functions in one location. This eliminates the need for each operator to deploy separate physical base stations, significantly reducing capital and operational costs while maintaining network capacity for multiple operators
Solution Approach 2:
A single base station is designed to serve multiple operators simultaneously through multi-RAN capability, making the infrastructure universal rather than dedicated to one operator. The base station can dynamically allocate resources to different operators based on demand, improving productivity without proportionally increasing costs
2Area of stationary object
If Base Station density is increased to improve coverage, then wireless coverage is improved, but inter-station interference increases
Solution Approach 1:
The base station implements dynamic resource allocation and spectrum sharing capabilities, allowing it to adaptively manage interference patterns in real-time based on the number and location of surrounding base stations. This dynamic adjustment enables higher density deployment while controlling interference through flexible spectrum assignment and power management
3Quantity of substance
If Base Station equipment is mounted on utility poles to reduce infrastructure costs, then capital costs are reduced, but manufacturing and maintenance costs increase
Solution Approach 1:
The base station equipment is segmented into modular, standardized units that can be efficiently manufactured and deployed on various infrastructure types including utility poles. This modularity reduces manufacturing complexity and enables easier maintenance and replacement, offsetting the increased complexity of distributed deployment
4Productivity
If public placement of wireless equipment is increased to expand coverage, then network capacity is improved, but public acceptance decreases
Solution Approach 1:
Multiple operators share existing infrastructure equipment located in publicly acceptable locations, rather than each operator deploying separate equipment. This consolidation reduces the total number of visible base stations while maintaining network capacity for multiple operators, thereby improving public acceptance

AI summary
Methods for a wireless Base Station (BS) capable of simultaneously providing service to subscribers of multiple Operators. Depending upon the particular deployment requirements or equipment capabilities, each Operator may be operating on the same or different frequencies (in which different frequencies may be adjacent, closely separated, or widely separated). The wireless BS will distinguish and logically separate and route the traffic between each subscriber device and its relevant Operator's Core Network, potentially supporting different logical or even different physical interfaces between the wireless BS and each Operator.
