Licensed Spectrum Sharing via Geo-location Database
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing spectrum management technologies face challenges in efficiently sharing licensed radio frequencies without compromising the confidentiality of the license holder's sensitive spectrum utilization information and network configurations, particularly in scenarios where licensed frequencies are underutilized by the owner.
Innovation Solution
A system comprising a geo-location database, a Decision Manager (DM), and an Operations, Administration, and Management (OAM) system that facilitates the shared use of licensed frequencies by calculating coverage areas, determining availability, and generating network plans that adhere to usage restrictions and permissions, ensuring confidentiality is maintained by not revealing specific network configurations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If spectrum sharing is implemented to increase spectrum utilization, then spectrum efficiency is improved, but confidentiality of network configuration information is compromised
Solution Approach 1:
The patent introduces a geo-location database as an intermediary component that stores spectrum usage information in a confidential manner. The database acts as a mediator between spectrum holders and sharing networks, allowing spectrum availability to be determined through geographic location queries without exposing detailed network configuration information. This resolves the contradiction by enabling spectrum sharing while maintaining confidentiality through the intermediary database layer.
2Productivity
If detailed spectrum usage information is shared to enable dynamic spectrum allocation, then spectrum efficiency is improved, but security of incumbent operations is worsened
Solution Approach 1:
The patent applies local quality by storing and retrieving spectrum usage information based on specific geographic locations rather than sharing universal or detailed network configuration data. The geo-location database allows spectrum availability to be determined locally for each geographic area where sharing is requested, providing just enough information for efficient allocation while maintaining security by not exposing broader network details. This resolves the contradiction by enabling efficient local spectrum allocation without compromising overall security.

AI summary
There is provided shared use of licensed frequency spectrum in a mobile communications network, while maintaining confidentiality between the license holder and the licensee. Geographical information on availability of licensed frequency spectrum for shared use is obtained. A site map of a mobile communications network is obtained. The site map includes locations of sites, where wireless access to the mobile communications network is provided. A configuration of frequencies for the sites on the basis of the available licensed frequencies for shared use at each location of the sites is determined.
