Base Station Authorization via Multiple Spectrum Controllers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Base stations in broadband networks like CBRS networks may needlessly stop operating due to the lack of periodic authorization from a spectrum controller, often caused by network outages or technical issues, leading to communication disruptions.
Innovation Solution
A computing device communicates with multiple spectrum controllers to request authorization for a base station, using virtual base stations with distinct serial numbers to avoid confusion, and combines or selects operating parameters from responses to ensure continuous operation even if communication with one controller is lost.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a base station requests authorization from a single spectrum controller, then the authorization process is simple and direct, but the base station may needlessly stop operating due to network outages or technical issues with that controller
Solution Approach 1:
The patent applies local quality by assigning different characteristics to different spectrum controllers. Specifically, virtual base stations are created with distinct serial numbers for each spectrum controller, allowing the system to tailor the authorization approach to each controller's response characteristics and availability, rather than treating all controllers uniformly
Solution Approach 2:
The patent implements preliminary action by proactively creating virtual base stations and establishing authorization requests with multiple spectrum controllers before actual operation is needed. This ensures that when one controller becomes unavailable, authorization is already secured through alternative controllers, preventing unnecessary shutdowns
2Reliability
If virtual base stations with distinct serial numbers are used for each spectrum controller, then authorization can be obtained from multiple controllers simultaneously, but the system complexity increases due to managing multiple virtual entities
Solution Approach 1:
The patent applies copying by creating virtual base stations that are essentially copies of the physical base station, each with a distinct serial number tailored for communication with specific spectrum controllers. These virtual copies simplify the interaction with multiple controllers while maintaining the core functionality of the single physical base station
3Adaptability or versatility
If the base station waits for periodic authorization from the spectrum controller, then spectrum usage is properly regulated and coordinated, but communication disruptions occur when authorization is not received due to network issues
Solution Approach 1:
The patent applies the intermediary principle by introducing virtual base stations as mediators between the physical base station and multiple spectrum controllers. These virtual entities handle the regulatory coordination requirements while the physical base station maintains continuous operation, decoupling the compliance function from the communication function

AI summary
A device, system and method to control operation of a base station is provided. A computing devices communicates, to two or more spectrum controllers, respective authorization requests associated with a physical base station at a given location, the two or more spectrum controllers managed by different respective entities. The computing device receives, from the two or more spectrum controllers, one or more respective spectrum controller responses to the respective authorization requests. When the one or more respective spectrum controller responses include at least one authorization associated with the physical base station, the computing device provides, to the physical base station, permission to operate via respective RF transmissions.
