Network Layer Re-Prioritization Using Device Performance Metrics
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Network providers prioritize network layers based on device capabilities and bandwidth, but fail to utilize device-specific performance metrics, leading to inefficient traffic steering and potential performance issues.
Innovation Solution
A system that utilizes Location Session Records (LSR) data to identify changes in device performance metrics, allowing for dynamic re-prioritization of network layers to avoid layers associated with performance issues, and proactively steer devices to higher-priority layers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If network layers are prioritized based on device capabilities and bandwidth, then network resource allocation is simplified, but device-specific performance issues are not addressed leading to inefficient traffic steering
Solution Approach 1:
The system dynamically changes the prioritization parameters of network layers based on device-specific performance metrics. When performance degradation is detected for a particular device type on a specific network layer, the system adjusts the priority values to steer traffic away from that layer for affected devices, thereby resolving the contradiction between simplified allocation and efficient traffic steering.
Solution Approach 2:
The system implements a feedback mechanism by continuously monitoring device performance metrics on different network layers. This feedback loop enables the system to identify performance issues and dynamically adjust network layer prioritization accordingly, improving traffic steering efficiency without significantly increasing system complexity.
2Productivity
If devices are steered to higher-priority network layers, then network efficiency is improved, but signaling stress on devices increases
Solution Approach 1:
The system applies local quality by implementing device-specific network layer prioritization rather than uniform prioritization for all devices. Each device receives customized prioritization based on its performance metrics, allowing efficient traffic steering for devices with performance issues while minimizing unnecessary signaling for devices that are already performing well.
3Reliability
If network layers are dynamically re-prioritized based on performance metrics, then device performance is improved, but system complexity increases
Solution Approach 1:
The system implements partial action by applying dynamic re-prioritization only to devices that exhibit performance degradation on specific network layers, rather than uniformly applying complex prioritization logic to all devices. This approach improves device performance for affected devices while limiting the increase in overall system complexity.

AI summary
Systems and methods are provided for managing network layers. Network providers often define their network with pre-defined network layer priorities depending on their spectrum holdings (e.g., bandwidth) and capability of devices. User device performance metrics are valuable data points that allow for intelligent traffic steering and network layer management based on device-specific performance related to specific network layers. Location session records (LSR) data provides detailed inputs for sessions for each user device in a network. This historical data can be utilized to identify performance issues on certain network layers for specific user devices and proactively steer the devices to other network layers to improve performance.
