Spectrum Access System Priority Classes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The 3.5 GHz Band, reserved for critical users, faces challenges in balancing quality of service for critical users with the need for non-critical users to access the spectrum, requiring a solution that maximizes efficient use while maintaining service quality.
Innovation Solution
A computerized system manages spectrum access by prioritizing devices into classes, allowing top priority devices immediate access and lower priority devices to contend for access, using a spectrum access system that registers and authorizes usage based on priority classes, ensuring efficient use and minimizing interference.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the 3.5 GHz band is reserved exclusively for critical users, then quality of service for critical users is maintained, but broadband capacity and spectrum utilization are limited
Solution Approach 1:
The patent segments the 3.5 GHz band into multiple priority classes (first priority class for critical users, second priority class for non-critical users). This segmentation allows critical users to have guaranteed access while enabling non-critical users to access unused spectrum resources, thereby resolving the contradiction between maintaining service quality and increasing broadband capacity.
Solution Approach 2:
The patent changes the parameter of spectrum access rights by introducing priority-based access mechanisms. Critical users retain exclusive access rights to ensure quality of service, while non-critical users are granted conditional access rights that do not interfere with critical user operations, thus increasing overall spectrum utilization without compromising reliability.
2Productivity
If non-critical users are allowed to access the 3.5 GHz band, then broadband capacity is increased, but interference to critical users may occur
Solution Approach 1:
The patent introduces a spectrum access system as an intermediary that manages and coordinates access between critical users and non-critical users. This intermediary monitors spectrum usage, enforces priority rules, and prevents non-critical users from causing interference to critical users, thereby enabling increased broadband capacity while protecting against harmful interference.
Solution Approach 2:
The patent implements dynamic access rights where non-critical users can access the spectrum only when it is not being used by critical users. The system dynamically adjusts access permissions based on real-time spectrum usage conditions, allowing broadband capacity to increase when spectrum is available while preventing interference when critical users are active.
3Productivity
If priority classes are implemented with registration and authorization processes, then spectrum access is optimized, but system complexity increases
Solution Approach 1:
The patent implements preliminary registration and authorization processes where non-critical users must register with the spectrum access system and obtain authorization before accessing the spectrum. This preliminary action organizes access requests and enables efficient spectrum allocation, optimizing spectrum access efficiency while managing system complexity through structured procedures.

AI summary
A system and computerized method for controlling access to shared spectrum in which access is prioritized among different classes of devices so that top priority devices have immediate access to the shared spectrum and lower priority devices contend for access. In some embodiments, the system and computerized method comprises managing a set of priority classes of devices to use the shared spectrum and granting rights to one or more of the requesting devices to use a portion of the shared spectrum during a requested use period based on a decision making process.
