5G Shared Spectrum Authorization Coordination for Service Continuity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing 5G wireless systems face challenges in efficiently managing spectrum authorization between transmission devices in shared spectrum environments, leading to potential service interruptions and inefficiencies due to asynchronous and independent authorization processes between base stations and terminal devices.
Innovation Solution
A system is proposed where base stations and terminal devices independently request and receive authorization from a spectrum administration system, with continuous communication to ensure synchronized and efficient channel usage, including periodic reconfirmation and proactive handover management to maintain service continuity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If base stations and terminal devices independently request and receive authorization from spectrum administration system, then spectrum utilization is improved, but service interruptions occur due to asynchronous authorization processes
Solution Approach 1:
The patent implements a feedback mechanism where the base station receives authorization status information from the spectrum administration system and forwards it to terminal devices. Terminal devices then feedback their authorization status to the base station, enabling continuous monitoring and coordination of authorization states across all network elements, thus preventing service interruptions caused by asynchronous authorization.
Solution Approach 2:
The patent enables preliminary action by allowing the base station to proactively determine when terminal devices need to request authorization from the spectrum administration system. The base station can initiate authorization requests before service interruptions occur, ensuring that terminal devices have valid authorization in advance, thereby maintaining service continuity while improving spectrum utilization.
2Ease of operation
If asynchronous independent authorization is used, then device autonomy is improved, but coordination efficiency deteriorates
Solution Approach 1:
The patent merges the independent authorization processes of base stations and terminal devices into a coordinated system. The base station maintains autonomy in determining authorization needs and managing the authorization process, while terminal devices autonomously execute authorization requests and report status. This combination preserves device autonomy while achieving efficient coordination through the base station's centralized management role.
3Reliability
If periodic reconfirmation and handover management are implemented, then service continuity is improved, but system complexity increases
Solution Approach 1:
The patent implements self-service by enabling terminal devices to autonomously monitor their own authorization status and automatically request new authorization when needed. The base station similarly monitors its own authorization and manages handovers autonomously. This self-service capability maintains service continuity through periodic reconfirmation and handover management without requiring complex centralized control mechanisms, thus limiting the increase in system complexity.

AI summary
Terminal devices can request and receive authorization to transmit on the same channel for which a serving base station that can serve the terminal devices has authorization to transmit. Upon transmit authorization or termination being received from a spectrum administration system, the base station can autonomously update the system information it broadcasts. Thus, terminal devices connected to the serving base station can be informed about the channel on which the terminal device should request authorization to transmit.
