Mobile Radio Spectrum Sharing for Time- and Location-Limited Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mobile radio frequency networks restrict access to radio spectrum ranges exclusively for registered users, limiting flexible and secure use by unregistered devices or temporary users.
Innovation Solution
A method and system for coordinated use of mobile radio frequencies, allowing unregistered devices to create private networks with time- and location-restricted access to a portion of the spectrum by using credentials and a central database for managing and allocating frequency bands, ensuring secure and fee-based usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If radio frequencies are allocated exclusively to primary users, then exclusive usage rights and secure access are ensured, but flexibility and adaptability for temporary or unregistered users are reduced
Solution Approach 1:
The patent segments the exclusive frequency range into multiple sub-frequency ranges that can be individually allocated to secondary users. The primary user retains exclusive rights to the overall frequency range, while specific sub-ranges can be temporarily shared with registered end users for private networks, enabling both secure primary access and flexible secondary usage.
Solution Approach 2:
The patent implements dynamic frequency allocation where the spectrum assignment changes based on time and user registration status. Frequencies dynamically transition between exclusive primary user access, shared access for registered end users creating private networks, and unavailable states, allowing the system to adapt to different operational requirements.
2Reliability
If access is restricted to registered users only, then network security and control are maintained, but ease of operation for unregistered devices is reduced
Solution Approach 1:
The patent introduces a registration system as an intermediary layer between unregistered devices and the frequency allocation mechanism. End users can register their devices to obtain credentials that enable private network formation, providing a convenient bridge that maintains security while allowing flexible access for previously unregistered devices.
3Reliability
If the entire frequency range is allocated to one user, then exclusive usage rights are ensured, but loss of spectrum resources is increased
Solution Approach 1:
The patent divides the exclusive frequency range into multiple allocable sub-frequency ranges, enabling the primary user to retain rights to the overall spectrum while allowing secondary users to access specific sub-ranges when needed. This segmentation prevents spectrum waste by enabling simultaneous or sequential usage by multiple users across different frequency portions.
Solution Approach 2:
The patent enables temporary discarding of exclusive rights for specific sub-frequency ranges to registered end users who need them for private networks, with automatic recovery of full exclusive rights when the temporary allocation period expires or the private network is deactivated, ensuring spectrum resources are continuously utilized without permanent loss.

AI summary
A method and a system with which a primary user, in particular a mobile radio operator, can make a part of the radio spectrum range which is reserved exclusively for the mobile radio operator available in localized and/or time-restricted fashion to a local end user who requested the restricted usage authorization of the radio spectrum range using registered credentials at the mobile radio operator. By way of the credentials the mobile radio operator can allow the local end user limited usage of that radio spectrum range in fee-bearing fashion and can bill same. The local user can then use the assigned frequency band in accordance with his own needs. In particular the user can wirelessly transmit signals in the assigned frequency range between end devices to which no credentials are allocated and in that situation use a transmission protocol which is not defined for the mobile radio network.
