Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Network nodes such as macrocell RANs, small/micro cell RANs, and Wi-Fi Access Points experience unnecessary restarts and disruptions due to GPS drift, leading to service interruptions and QoS issues.
Innovation Solution
Incorporating a velocity sensor into network nodes to verify the accuracy of GPS-perceived location changes, preventing unnecessary restarts by inhibiting initialization when GPS drift is detected.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If network nodes perform cold or warm restart to validate location changes, then frequency selection and radiation permissions are ensured, but network services are disrupted for 5 minutes to 24 hours
Solution Approach 1:
A velocity sensor is introduced as an intermediary component to verify whether location changes are genuine. The sensor acts as a mediator between the GPS receiver and the initialization trigger, filtering out false location changes caused by GPS drift while allowing legitimate relocation events to proceed with restart procedures.
Solution Approach 2:
The velocity sensor provides feedback about actual motion status to the initialization logic. This feedback mechanism allows the system to distinguish between genuine location changes (where motion is detected) and GPS drift (where no motion is detected), thereby preventing unnecessary restarts and service disruptions.
2Reliability
If network nodes frequently validate location to ensure correct frequencies are used, then regulatory compliance is maintained, but network services experience repeated interruptions
Solution Approach 1:
The velocity sensor serves as an intermediary verification layer that filters location validation events. It allows the system to maintain regulatory compliance by validating location changes while preventing false validations triggered by GPS drift, thereby reducing unnecessary service interruptions.
Solution Approach 2:
The system uses its own velocity sensor data to self-validate whether location changes are genuine before triggering initialization procedures. This self-service mechanism reduces reliance on frequent external validations while maintaining compliance, thereby improving service continuity.
3Measurement precision
If GPS location information is used to determine transmit power levels, then frequency coordination is optimized, but QoS is impacted when power is reduced due to imprecise location data
Solution Approach 1:
The velocity sensor provides feedback on actual motion to verify GPS location changes. This feedback mechanism prevents transmit power reductions based on false location changes from GPS drift, thereby maintaining appropriate power levels and QoS while still optimizing frequency coordination based on accurate location data.
Solution Approach 2:
The velocity sensor acts as an intermediary verification layer between GPS location data and transmit power determination. It filters out false location changes that would otherwise lead to incorrect power level adjustments, ensuring QoS is maintained while location-based optimization is preserved.

AI summary
Various embodiments comprise systems, methods, architectures, mechanisms and apparatus wherein network nodes such as macrocell RANs, small/micro cell RANs, Wi-Fi Access Points (APs) and the like are modified to include a velocity sensor configured to determine if any GPS-perceived location change is accurate and, if not, to avoid or inhibit invoking restart/initialization of the network node normally invoked in response to the change in location of the network node.
