Unified CBSD Domain Proxy for CAT A/B Spectrum Registration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current CBRS networks face inefficiencies due to the need for separate domain proxies for CAT A and CAT B CBSDs, leading to service outages during upgrades and lack of clear channel quality information, which complicates frequency allocation and TDD configuration.
Innovation Solution
A unified domain proxy system integrates CAT A and CAT B CBSD management, utilizing a single proxy to handle both types, incorporating a Self-Organizing Network (SON) and Auto Configuration Server (ACS) to optimize frequency allocation and channel quality management, with support for both indoor and outdoor deployments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate domain proxies are used for CAT A and CAT B CBSDs, then compliance control is maintained, but device complexity increases and service outages occur during upgrades
Solution Approach 1:
The patent merges the functionality of separate domain proxies for CAT A and CAT B CBSDs into a single unified domain proxy. This unified proxy maintains the ability to provide positive control and compliance verification for both CBSD categories while eliminating the need for separate proxy instances, thereby reducing overall system complexity and removing service outages during upgrades.
Solution Approach 2:
The unified domain proxy is designed with multi-functionality to handle both CAT A and CAT B CBSDs through a single instance. It performs universal compliance control, spectrum access management, and coordination functions for diverse CBSD types, replacing the previous requirement for category-specific dedicated proxies.
2Reliability
If separate domain proxies are used for CAT A and CAT B CBSDs, then category-specific control is maintained, but service interruptions increase during network upgrades
Solution Approach 1:
By combining multiple domain proxy functions into a single unified proxy that supports both CAT A and CAT B CBSDs, the system eliminates service interruptions during upgrades. The unified proxy can be updated in-place without requiring separate replacement operations for different CBSD categories, thereby reducing or eliminating service outage time while maintaining category-specific control capabilities.
3Device complexity
If a single unified domain proxy is used for both CAT A and CAT B CBSDs, then device complexity is reduced, but channel quality information becomes less clear
Solution Approach 1:
The unified domain proxy applies local quality differentiation by maintaining distinct channel quality information and allocation parameters for different CBSD categories and locations. While the proxy structure itself is simplified, it preserves detailed channel quality metrics (such as EIRP levels, frequency allocations, and interference characteristics) specific to each CBSD type and geographic location, ensuring that channel quality information remains clear and actionable.

AI summary
A method that is implemented by a domain proxy is disclosed. The method includes registering a first CBSD (Citizen Band Service Device) with a SAS (Spectrum Access System) to allow the first CBSD to gain access to frequencies in a CBRS (Citizen Band Radio System), the first CBSD being a Category A CBSD. In addition, registering a second CBSD with the same or another SAS to allow the second CBSD to gain access to frequencies in a CBRS, the second CBSD being a Category B CBSD.
