Central Routing Function Dynamic Call Route Prioritization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current communication systems face inefficiencies in routing domestic and international long-distance calls due to unpredictable changes in call route loads and varying costs across different carriers, leading to suboptimal call routing and quality of service.
Innovation Solution
A central routing function (CRF) platform that generates and manages prioritized call route lists based on key performance indicators (KPIs) and percentage allocation rules, ensuring efficient routing by selecting the highest priority routes dynamically in response to changing network conditions and carrier performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional static routing methods are used, then system simplicity is maintained, but network efficiency and call routing optimization deteriorate due to inability to adapt to changing loads and carrier performance
Solution Approach 1:
The patent implements dynamic routing by continuously monitoring key performance indicators (KPIs) such as call success rates, blocking rates, and trunk utilization, then automatically adjusting route prioritization in real-time. The CRF platform dynamically reconfigures call routes based on changing network conditions, transforming the static routing system into an adaptive dynamic system that optimizes network efficiency without requiring manual intervention.
Solution Approach 2:
The system employs feedback mechanisms by collecting performance data from network elements during call routing, analyzing KPIs, and using this information to adjust routing decisions. The CRF receives feedback on call outcomes and network status, then modifies route selection and prioritization accordingly, creating a closed-loop control system that continuously improves routing efficiency based on actual performance data.
2Adaptability or versatility
If manual route management is used, then system complexity is low, but adaptability to changing network conditions and carrier performance deteriorates
Solution Approach 1:
The routing system performs self-service by automatically monitoring its own performance through KPI collection, identifying suboptimal routes, and reconfiguring call routing without external intervention. The CRF platform autonomously adjusts route prioritization based on real-time network conditions and carrier performance, enabling the system to self-optimize and adapt to changing conditions without manual route management.
Solution Approach 2:
The system performs preliminary actions by pre-establishing multiple alternative call routes and pre-configuring prioritization schemes for different call types and network conditions. When network conditions change, the system can quickly switch to pre-planned alternative routes, enabling rapid adaptation without requiring complex real-time decision-making, thus balancing automation with manageable complexity.
3Reliability
If prioritized route lists are not adapted, then routing speed is maintained, but loss of information about optimal routing deteriorates due to unchanged routes despite load changes
Solution Approach 1:
The system implements periodic action by regularly updating route prioritization at scheduled intervals or when threshold-based triggers are activated. The CRF monitors network conditions continuously and periodically reconfigures routing tables when significant changes are detected, balancing the need for up-to-date routing information with the overhead of frequent updates. This periodic adaptation ensures routing reliability while minimizing unnecessary reconfiguration overhead.
Data Source
AI summary
A central routing function (CRF) platform. The CRF platform comprises a processor, a memory that stores prioritized call route lists, and an application stored in the memory. When executed by the processor the application receives a request for a prioritized call route list from a network element, where the request comprises an indication of a location of a call originator of a call and a destination telephone number, determines a call type of the call, selects a prioritized call route list associated with the destination telephone number from the non-transitory memory based on the call type, determines that a percent allocation rule applies to the call, based on the percent allocation rule, removes the first priority call route from the selected prioritized call route list to make an adapted prioritized call route list, and sends the adapted prioritized call route list to the network element.
