Dynamic Rerouting of Wireless Data Paths via Performance Analysis
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional wireless communication networks discard performance data from HARQ methods, preventing effective fault detection and rerouting in wireless networks, which hampers service quality for users.
Innovation Solution
The system dynamically reroutes active communication sessions through femtocells or satellite links based on performance data analysis, identifying and addressing failed network elements by blocking access or rerouting traffic, and unblocking restored elements to maintain network integrity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If performance data from HARQ methods is collected and utilized for fault detection, then network reliability is improved, but device complexity increases
Solution Approach 1:
The system enables performance data to serve multiple functions: it is used both for the original HARQ retransmission process and for fault detection and network element identification. By making the collected data multi-functional, the patent avoids the need for separate dedicated fault detection mechanisms, thereby improving reliability without proportionally increasing device complexity
Solution Approach 2:
The system uses its own existing performance data collection mechanisms to automatically detect faults and identify failed network elements. The HARQ performance data that is already being collected for communication purposes is repurposed to self-diagnose network issues, eliminating the need for external or additional complex monitoring systems
2Reliability
If performance data is collected and analyzed for fault detection, then service quality is improved, but loss of time increases
Solution Approach 1:
The system continuously collects and analyzes performance data in advance, maintaining a historical record of network performance. This preliminary action enables the system to quickly identify faults when they occur by comparing current performance against established baselines, rather than starting detection from scratch when a problem arises
Solution Approach 2:
The system implements continuous feedback loops where performance data is collected, analyzed, and used to identify faults in real-time. The feedback mechanism allows the system to automatically detect and respond to network issues as they develop, minimizing the time loss by providing timely information about deteriorating network conditions
3Reliability
If dynamic rerouting is implemented based on performance data, then network reliability is improved, but device complexity increases
Solution Approach 1:
The patent introduces a network element identification system that acts as an intermediary between performance data collection and rerouting decisions. This intermediary layer processes the data, identifies failed elements, and determines optimal alternative paths, thereby automating the complexity rather than requiring direct complex decision-making at each device level
Solution Approach 2:
The system implements dynamic rerouting that automatically adapts to changing network conditions. When faults are detected, the system dynamically updates routing paths based on current performance data, allowing the network to flexibly respond to failures without requiring manual reconfiguration or complex static routing tables
Data Source
AI summary
A system and methodology that dynamically reroutes active communications sessions between a user equipment (UE) and a wireless network. In particular, the system can determine a current or impending fault condition and reroute a data path for network traffic to another service. Moreover, the system can identify a failed element in a wireless network and deny access and divert traffic until the element is restored. Further, the system can issue an alert to a user interface of the wireless network with information associated with a fault condition, a failed element, or a restored element.
