CBRS Jamming Mitigation via WiFi-Assisted UE Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems lack the ability to identify and mitigate interference caused by unregistered Citizens Broadband Radio Service Devices (CBSDs) in the Citizens Broadband Radio Service (CBRS) band, as the Spectrum Access System (SAS) cannot control such devices if they are not registered.
Innovation Solution
Incorporating mobile network user equipment (UE) information into WiFi network communications to detect potential jamming conditions and communicate UE identification to service provider equipment, enabling the identification and mitigation of CBSDs experiencing interference.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the SAS controls only registered CBSDs, then the system maintains manageable device control, but unregistered devices can cause jamming without detection or mitigation
Solution Approach 1:
The patent introduces WiFi access points and mobility management entities as intermediary components that enable indirect monitoring and control of unregistered CBSDs. These intermediaries detect jamming conditions through WiFi communications and facilitate UE migration without requiring direct SAS control of unregistered devices, thus maintaining reliability while avoiding direct complexity with unregistered devices
Solution Approach 2:
The system implements feedback mechanisms where WiFi access points monitor radio conditions and report jamming detection to mobility management entities. This feedback loop enables the system to respond to unregistered device interference without requiring prior knowledge or direct control of those devices, resolving the contradiction between detecting all interference sources and maintaining simple device control
2Reliability
If the system migrates UEs away from jammed CBSDs, then service continuity is maintained, but network resources and signaling overhead increase
Solution Approach 1:
The system performs preliminary actions by pre-configuring alternative CBSD connections for UEs and maintaining readiness to migrate connections before jamming occurs. The mobility management entity pre-identifies alternative CBSDs, so when jamming is detected, UEs can be quickly redirected using pre-prepared information, reducing the signaling overhead and energy consumption that would result from ad-hoc migration decisions
Solution Approach 2:
The system enables UEs to self-manage their connectivity by allowing them to select from available CBSDs based on conditions reported by the network. The mobility management entity provides information about alternative CBSDs, and UEs can autonomously initiate reconnection attempts, reducing the signaling overhead required for network-controlled handovers and minimizing energy consumption

AI summary
Various embodiments comprise systems, methods, architectures, mechanisms and apparatus for managing service provider network nodes in a converged network by inserting mobile network UE information into WiFi network communications such that a WiFi control entity may, in response to determining that the UE-inserted information is indicative of a jamming condition at a Citizens Broadband Radio Service Devices (CBSDs) providing mobile network services to the UE, communicate the identification of such UE to various provider equipment such that CBSDs experiencing jamming signals may be identified and mitigation steps taken.
