Spectrum Micro-lease Management via Hierarchical Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing spectrum allocation methods are inefficient as they do not allow for micro-leases in smaller geographic areas, leading to sub-optimal use of wireless spectrum.
Innovation Solution
A system and method for managing spectrum micro-leases, which includes a processor and database to track and manage micro-leases in small geographic areas, allowing for efficient spectrum sharing between micro-lease holders and wide area lease holders.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If spectrum is allocated to large geographic areas, then spectrum allocation is simplified, but spectrum utilization efficiency deteriorates
Solution Approach 1:
The patent divides large geographic spectrum allocations into smaller micro-leases covering specific buildings or premises. The system manages multiple lease levels where a wide area lease can be segmented into multiple micro-leases, each with its own boundary definition and lease terms, enabling precise spectrum allocation to match actual usage requirements.
Solution Approach 2:
The patent introduces a hierarchical lease structure that adds a new dimension to spectrum management. Instead of only managing spectrum at the broad geographic level, the system creates a multi-level hierarchy where wide area leases can be subdivided into micro-leases, allowing spectrum to be allocated at different geographic granularities simultaneously.
2Productivity
If micro-leases are implemented in small geographic areas, then spectrum utilization efficiency is improved, but system complexity increases
Solution Approach 1:
The patent creates a universal lease management system that can handle multiple lease types (wide area leases and micro-leases) within a single framework. The same system infrastructure, database schemas, and management processes can accommodate both broad and granular spectrum allocations, eliminating the need for separate management systems for different lease scales.
Solution Approach 2:
The patent implements a nested lease structure where micro-leases can be contained within wide area leases. The system allows hierarchical organization where smaller geographic micro-leases are nested within larger geographic wide area leases, enabling a single system to manage multiple levels of spectrum allocation without requiring completely separate management architectures.
3Adaptability or versatility
If multiple lease levels are allowed, then spectrum sharing flexibility is improved, but interference management difficulty increases
Solution Approach 1:
The patent applies different quality characteristics to different lease levels. Wide area leases and micro-leases can have different service quality requirements, priority levels, and interference tolerance parameters. The system manages these local quality differences by allowing each lease level to be configured with its specific quality parameters while maintaining overall system coordination.

AI summary
A system and method for managing spectrum micro-leases of a portion of a geographic area associated with a micro area network and based on a spectrum lease of a wireless spectrum of a wide area network covering the geographic area. A system includes a processor and a database having an information store. The information store is configured to store an accounting record of all spectrum leases, including micro-leases, the accounting record including a location of the spectrum lease and a description of the border of the geographic area associated with the spectrum lease. The processor is configured to manage one or more micro-leases of the portion of the geographic area, and configured to receive and detect a network ID being used by the wide area network, and which informs the micro area network of the network ID. The micro area network then broadcasts the wide area network ID in addition to the micro network ID, allowing users of the wide area network to access the micro area network.
