Licensed Spectrum Device-to-Device Communication via Validation Server
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication standards face limitations in device-to-device communication quality due to restrictions in unlicensed radio spectra, particularly in crowded areas, and lack effective methods for managing licensed spectrum usage between proximate devices.
Innovation Solution
A method and system for establishing a wireless communication relationship between devices using licensed radio spectrum, involving a remote validation server for authorization and proof of validation messages to facilitate controlled communication, enabling improved quality and managed access through subscription and charging controls.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If devices communicate via unlicensed radio spectra (ISM bands), then wireless communication between proximate devices is enabled, but communication quality deteriorates due to power limitations and spectral crowding
Solution Approach 1:
A validation server acts as an intermediary between devices seeking to communicate via licensed spectrum. The server validates device identities, checks subscription statuses, and authorizes communication sessions. This mediator enables reliable licensed spectrum communication by managing authentication and control functions that would otherwise require complex device-to-device protocols.
2Reliability
If licensed spectrum is used for device-to-device communication, then communication quality improves, but spectrum licensee control is reduced without proper management mechanisms
Solution Approach 1:
The validation server implements feedback mechanisms by continuously monitoring device subscription statuses, billing information, and communication session states. The server receives updates from network entities about subscription changes and automatically adjusts authorization decisions accordingly, providing real-time feedback control over licensed spectrum usage without requiring manual intervention.
Solution Approach 2:
The validation server serves as an intermediary that maintains spectrum licensee control by managing authentication, subscription verification, and session authorization. This mediator ensures that licensed spectrum is used only by authorized devices with valid subscriptions, preserving licensee control while enabling device-to-device communication.
3Productivity
If subscription and charging control is implemented for licensed spectrum usage, then revenue streams are created and spectrum management is improved, but system complexity increases
Solution Approach 1:
The patent extracts subscription management, billing verification, and authorization functions from the device-to-device communication protocol and places them in a separate validation server. This extraction centralizes complex control logic in a dedicated network entity, reducing the complexity burden on communicating devices while maintaining comprehensive subscription and charging control for revenue generation.

AI summary
A method and system for facilitating a controlled wireless communication relationship between a first device and a second device is provided. The wireless communication relationship is established at least in part via a portion of licensed radio spectrum. A remote validation server is contacted to obtain a validated authorization to use the portion of licensed radio spectrum for radio communication. Proof of the authorization between the first device and the second device is communicated. The first device and the second device subsequently enter into an authorized wireless communication relationship.
