Centralized Routing Table Generation for VoIP Network Elements
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing VOIP networks face significant computational and data storage burdens due to large routing tables that require extensive processing and storage, making them costly and difficult to implement as telecommunication systems grow in complexity.
Innovation Solution
A system where a carrier data center generates customized, real-time routing tables for each call using a small subset of relevant data, reducing computational requirements and storage needs by centralizing the task of calculating routing data and shifting it from network elements to the data center.

Engineering Contradiction Analysis
1Reliability
If routing tables are generated periodically and stored at call stations, then routing options are available for call handling, but computational requirements and data storage burden increase enormously
Solution Approach 1:
The patent extracts the routing table generation function from distributed call stations and concentrates it in a centralized Rate/Route Management System (RRMS). This removes the computational and storage burden from individual network elements while maintaining routing capability. The RRMS generates routing tables centrally and distributes them to call stations, eliminating the need for each station to independently store and process large routing datasets.
Solution Approach 2:
The patent merges the routing management functionality into a single centralized system (RRMS) that handles route determination, cost calculation, and routing table generation for the entire network. This consolidation reduces the overall computational and storage requirements by eliminating redundancy across multiple distributed systems while maintaining comprehensive routing capability.
2Adaptability or versatility
If routing tables include all possible routing options, then complete routing flexibility is achieved, but storage requirements become huge
Solution Approach 1:
The RRMS performs preliminary calculations and pre-determines optimal routing paths based on current network conditions, costs, and policies before calls are established. Routing tables are generated in advance with pre-calculated best routes, eliminating the need to store all possible routing combinations. Call stations receive these pre-computed routing tables and can execute them without real-time computation.
Solution Approach 2:
The patent implements location-specific routing tables tailored to each call station's characteristics, served networks, and local pricing structures. Instead of maintaining a single universal routing table with all possible routes, each call station receives customized routing information relevant to its specific context, reducing storage requirements while maintaining routing flexibility for local decisions.
