Automated CPE Provisioning for CBRS Spectrum Compliance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing manual process for configuring Customer Premises Equipment (CPE) to operate within specific spectral regions, such as the Citizens Broadband Radio Service (CBRS) band, is tedious and error-prone, requiring manual intervention and certified professional installation, especially for Category B devices, which hinders efficient spectrum management and registration with a Spectrum Access System (SAS).
Innovation Solution
A substantially automated system that identifies CPE capabilities during installation, configures them to operate within allowed spectral regions, and generates approval-ready credentials for registration with a SAS, ensuring compliance with CBRS frequency bands and transmit power levels, thereby streamlining the provisioning and registration process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If manual configuration process is used to configure CPE to operate within CBRS band, then CPE can be configured to operate within allowed spectral region, but the process is tedious and error-prone requiring certified professional installation
Solution Approach 1:
The system performs preliminary configuration actions automatically during the provisioning process. The network entity retrieves CPE capability information beforehand, determines appropriate configuration parameters, and applies constraints before the CPE begins operation, eliminating the need for manual post-installation configuration
Solution Approach 2:
The CPE device automatically provides its capability information to the network entity through standardized interfaces. The system then automatically processes this information, determines configuration parameters, and applies constraints without requiring human intervention, enabling the system to service itself
2Reliability
If manual CPE credential approval process is used before SAS registration, then spectrum management compliance can be ensured, but the registration process efficiency is reduced
Solution Approach 1:
The network entity performs preliminary determination of CPE configuration parameters and generates configuration information before CPE registration with the SAS. This preliminary action ensures compliance is established in advance, enabling faster registration without sacrificing reliability
Solution Approach 2:
The system implements a feedback mechanism where the network entity receives CPE capability information, processes it through automated determination logic, and generates appropriate configuration parameters. This closed-loop feedback process ensures compliance while automating the workflow to improve registration speed
3Adaptability or versatility
If CPE operational capability is not constrained, then CPE can operate in wider spectral region, but CPE may operate outside allowed CBRS band causing interference
Solution Approach 1:
The system applies different operational constraints to different CPE devices based on their specific capabilities and deployment contexts. The network entity determines configuration parameters tailored to each CPE's characteristics, allowing maximum operational flexibility within the CBRS band while preventing out-of-band emissions through device-specific constraint application
Solution Approach 2:
The system dynamically changes operational parameters such as frequency limits, power levels, and bandwidth constraints based on CPE capability information and network conditions. By adjusting these parameters automatically, the system enables CPE to operate at the boundaries of allowed spectral regions without causing interference, optimizing both adaptability and harm prevention

AI summary
Various embodiments comprise systems, methods, and apparatus providing substantially automated provisioning and provisioning management of CPE within a system using unlicensed spectrum so as to ensure that the CPE operate only within an allowed spectral region irrespective of CPA capability. The automated system utilizes an identification of CPE being installed to automatically determine CPE capability, configure the CPE as needed to avoid CPE operation outside of the allowed spectral region, and generate approval-ready CPE credentials suitable for use by a Spectrum Access System (SAS).
