Private Cellular Assurance Layers for Accurate Endpoint Service Assessment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing private cellular network architectures fail to evaluate service performance based on information from client devices, leading to inaccurate end-point perception of service behavior.
Innovation Solution
A multi-layer client assurance architecture is implemented in private cellular networks, incorporating multiple assurance points to obtain measurements from different network layers, combining them to determine network service levels and ensure compliance with service level agreements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If existing PCN architectures evaluate service performance based only on network infrastructure parameters, then network management is simplified, but service performance assessment accuracy deteriorates due to lack of end-point perspective
Solution Approach 1:
The patent segments the service performance assessment into multiple layers: network infrastructure layer (RAN, core network) and end-point layer (client devices, applications). Each layer has dedicated assurance points that collect and report metrics independently, allowing comprehensive assessment without overwhelming centralization.
Solution Approach 2:
The patent introduces assurance points as intermediary components deployed at strategic locations including client devices, network infrastructure, and application layers. These intermediaries collect, process, and report performance metrics, bridging the gap between network infrastructure and end-user experience without requiring direct complex interactions between all components.
2Reliability
If multiple assurance points are deployed across different network layers to obtain comprehensive measurements, then service behavior assessment accuracy improves, but system complexity increases
Solution Approach 1:
The patent designs assurance points with universal functionality that can operate across multiple network layers and contexts. Each assurance point is capable of collecting diverse metrics (quality indicators, performance data, service level information) and adapting to different deployment scenarios, reducing the need for specialized components for each layer.
Solution Approach 2:
The patent implements feedback mechanisms where assurance points continuously monitor service performance, compare actual metrics against service level agreements, and trigger appropriate responses. This closed-loop feedback system ensures reliable SLA compliance by automatically detecting violations and enabling corrective actions without requiring complex manual intervention systems.

AI summary
A system and method of performing multi-layer client assurance in a private cellular network includes a plurality of assurance points within the network. The method includes receiving, by a network entity, a plurality of parameter sets from the plurality of assurance points. Each of the plurality of assurance points can be configured to obtain measurements from a portion of the private cellular network corresponding to a client assurance layer in a client assurance stack. The method can include combining a first parameter set from the plurality of parameter sets with a second parameter set from the plurality of parameter sets. The first parameter set can be associated with a first client assurance layer and the second parameter set is associated with a second client assurance layer. The method can include determining, based on the combined parameter set, a network service level corresponding to the client device.
