Dynamic Connectivity Map Service for Spectrum Optimization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional techniques for providing radio channel maps or spectrum availability maps in wireless networks are static and do not reflect dynamic changes in spectrum availability or connectivity options for access points (APs), failing to optimize the use of shared spectrum due to factors like dynamic protection areas and priority access licenses.
Innovation Solution
A connectivity map service application program interface (API) is configured to create, store, and maintain dynamic connectivity maps for each AP across multiple shared spectrum bands, providing real-time or near real-time information on available channels and transmit power, and utilizing machine-learning algorithms to predict availability and optimize spectrum allocation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If static spectrum availability maps are used, then implementation complexity is reduced, but the accuracy and real-time reflection of actual spectrum availability deteriorates
Solution Approach 1:
The patent transforms static spectrum availability maps into dynamic maps that are continuously updated based on real-time environmental sensing data, incumbent user activity, and SAS allocation decisions. This allows the system to reflect actual spectrum availability conditions dynamically, resolving the contradiction between implementation simplicity and accuracy.
Solution Approach 2:
The system implements feedback loops where Environmental Sensing Capability (ESC) devices monitor spectrum usage, report to the SAS, which then updates the connectivity map accordingly. This continuous feedback mechanism ensures the map remains accurate without requiring complex manual updates, balancing simplicity and precision.
2Productivity
If dynamic connectivity maps are implemented, then spectrum utilization efficiency is improved, but information processing complexity increases
Solution Approach 1:
The patent segments the spectrum management function into distinct components: ESC devices for environmental sensing, SAS for centralized coordination and map generation, and APs for local implementation. This segmentation distributes processing complexity across multiple entities, enabling dynamic map updates without overwhelming a single system.
Solution Approach 2:
The SAS acts as an intermediary that receives raw sensing data from multiple ESC devices, processes it centrally, and generates simplified connectivity maps for APs. This intermediary role reduces the information processing burden on individual APs while maintaining high spectrum utilization efficiency through coordinated management.
3Speed
If connectivity maps are updated in real-time, then responsiveness to spectrum changes is improved, but computational overhead increases
Solution Approach 1:
The system implements periodic updates of connectivity maps at intervals determined by the SAS, rather than continuous real-time updates. This periodic action maintains responsiveness to spectrum changes while significantly reducing computational overhead compared to continuous updates, as the map is refreshed only when necessary based on incumbent activity or SAS decisions.

AI summary
Methods and systems for providing a connectivity map to a user equipment (UE) in a wireless network are disclosed. Exemplary methods comprise receiving a request for connectivity information from the UE, sending the request for connectivity information to a connectivity map service application program interface (API), receiving, from the connectivity map service API, a connectivity map, and sending the connectivity map to the UE in response to the request for connectivity information. The connectivity map may be generated using a location and state information associated with one or more nearby APs stored in a database and may comprise a list of available spectrum and one or more parameters associated with each available spectrum. The connectivity map may be used to select at least one of a network, a data-path, a network route, a connectivity strategy, or a spectrum for the UE.
