Commoditized Spectrum Object Provisioning and Allocation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current spectrum allocation methods, such as direct spectrum allocation, are inefficient as they do not consider communication efficiency and interference issues, leading to suboptimal performance and high inefficiencies in spectrum utilization.
Innovation Solution
A provisioning engine generates a commoditized spectrum object with defined parameters like signal strength limits, frequency, and time, which is then allocated by an allocation engine to ensure efficient, interference-free spectrum usage, allowing for efficient spectrum trading and allocation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If direct spectrum allocation is used, then spectrum allocation is simple and fast, but spectrum utilization efficiency is low and interference is not minimized
Solution Approach 1:
The spectrum is divided into multiple spectrum objects with different parameters (signal strength limits, frequency ranges, time periods, geographic areas). Each spectrum object can be independently allocated to different users based on their specific needs, allowing efficient spectrum utilization while maintaining manageable system complexity through modular segmentation.
Solution Approach 2:
The system dynamically allocates spectrum objects based on real-time requirements rather than fixed allocations. The allocation engine considers current signal strength limits, interference conditions, and user demands to make dynamic decisions, improving spectrum utilization efficiency without requiring overly complex predetermined allocation rules.
2Reliability
If conventional spectrum allocation is used, then the allocation process is simple, but communication performance is suboptimal due to lack of interference consideration
Solution Approach 1:
The system incorporates feedback mechanisms where the allocation engine receives information about actual signal strength and interference conditions, then adjusts spectrum allocations accordingly. This feedback loop enables the system to optimize communication performance by adapting to real-time interference conditions while managing complexity through automated feedback-based decision making.
Solution Approach 2:
The system changes allocation parameters such as signal strength limits, frequency assignments, and time periods based on actual communication conditions. By dynamically adjusting these parameters rather than using fixed allocation rules, the system optimizes communication performance while the automated parameter adjustment manages the complexity of multi-parameter optimization.
3Object-affected harmful factors
If spectrum is allocated without considering signal strength limits, then allocation is faster and simpler, but interference with existing networks increases
Solution Approach 1:
The system performs preliminary actions by pre-defining spectrum objects with specific signal strength limits and interference constraints before actual allocation occurs. The allocation engine uses these pre-configured parameters to quickly determine valid allocations without needing to perform complex real-time calculations, thus preventing interference while maintaining allocation speed.
Solution Approach 2:
The allocation engine acts as an intermediary between spectrum providers and users, automatically handling the complex interference avoidance calculations. This intermediary function filters out potentially interfering allocations based on pre-established signal strength limits and geographic constraints, preventing harmful interference while the automated mediation maintains fast allocation processing.

AI summary
A provisioning engine provisions spectrum into an allocable spectrum object. The provisioning engine includes an interface configured to receive inputs of available spectrum information and a plurality of provisioning parameters. The plurality of provisioning parameters include at least one signal strength limit, and may include at least first and second signal strength limits that may be boundary strength limit and an allocation strength limit. A controller is configured to execute a spectrum provisioning application that is stored in a memory and, by execution of the spectrum provisioning application, the provisioning engine is configured to generate an allocable spectrum object in accordance with the provisioning parameters. Spectrum encompassed within the spectrum object is allocable by an allocation engine to spectrum users in accordance with the provisioning parameters. An allocation engine in turn allocates spectrum encompassed within the provisioned spectrum object in accordance with the provisioning parameters.
