Central Control System for Spectrum Time Normalization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Radio devices, especially mobile ones, struggle to accurately comply with spectrum protection regulations due to imprecise knowledge of time zones and daylight savings time, leading to potential interference in protected spectrum usage.
Innovation Solution
A system that normalizes time values for spectrum requests and allocations, using a central control system to convert local time to a universal time system, allowing radio devices to determine available channels without needing precise time knowledge, and managing spectrum use to avoid protected venues by providing re-request times and channel lists.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If radio devices use GPS to obtain location and absolute time, then they can acquire time information, but they cannot accurately determine local time due to time zone differences and daylight savings time
Solution Approach 1:
The patent introduces a central control system as an intermediary that performs time zone conversion. The system receives time information from radio devices, determines the device's time zone based on location data, converts the time to local time, and provides the converted time back to the device. This intermediary approach allows devices without sophisticated time zone handling capabilities to still achieve accurate local time determination.
Solution Approach 2:
The patent replaces the mechanical approach of having radio devices independently calculate and manage time zone conversions with a centralized system that handles time zone conversion automatically. Instead of devices managing their own time complexity, the central control system substitutes this complex task with a centralized service that simplifies the device's operation.
2Reliability
If the system provides detailed time-based spectrum protection information, then compliance with spectrum regulations is improved, but the complexity of time management for radio devices increases
Solution Approach 1:
The central control system acts as an intermediary that handles all time-based complexity. It receives protection time information, converts it to the device's local time zone, and provides the device with simplified local time information. This allows the device to comply with spectrum protections without needing to manage complex time zone conversions itself.
Solution Approach 2:
The patent enables the central control system to perform time zone conversion automatically without requiring the radio device to actively manage time zone logic. The device simply provides its location and receives converted time information, making the system self-sufficient in handling time management complexities.

AI summary
Spectrum that will become venue-protected in the future is made available to radio devices by a central control system with which the radio devices requests spectrum access information for use in wireless communication. The central control system establishes a re-request time duration specified in an amount of time that will elapsed at or before the spectrum becomes protected. The elapsing of the re-request duration serves as a command to the radio device to transmit a new channel request to the central control system.
