VoIP Server Geolocation Routing via Confidence Thresholds
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
VoIP systems face challenges in accurately determining the geographic location of endpoint devices due to dynamic IP addresses and the lack of a single authoritative source for geolocation data, leading to inconsistent call routing and quality.
Innovation Solution
A VoIP server system that retrieves geographic location information from endpoint devices, compares it with IP address-based data, and updates a location database to select optimal routing options based on confidence levels and trigger events, ensuring accurate carrier and media server selection for improved call quality and cost-effectiveness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If VoIP systems use dynamic IP addresses for endpoint devices, then flexibility in geographic location is improved, but geolocation accuracy deteriorates
Solution Approach 1:
The system performs preliminary actions by establishing multiple independent geolocation data sources (IP address database lookup, endpoint device GPS coordinates, Wi-Fi network location data) before making routing decisions. This allows the system to have location information ready in advance, improving both flexibility and accuracy by not relying on a single dynamic source.
Solution Approach 2:
The patent introduces intermediary components including a location database that stores pre-mapped IP address to location relationships, and a confidence level mechanism that acts as a mediator to evaluate and weight different geolocation sources. These intermediaries bridge the gap between dynamic IP addresses and accurate geolocation by providing structured data layers.
2Stability of the object's composition
If VoIP systems rely on a single authoritative source for geolocation data, then data consistency is improved, but adaptability to dynamic IP changes deteriorates
Solution Approach 1:
The system merges multiple geolocation data sources including IP address database lookups, endpoint device-provided GPS coordinates, and Wi-Fi network location data into a unified location determination process. This combination allows the system to maintain data consistency through validation while adapting to dynamic IP changes by cross-referencing multiple sources.
Solution Approach 2:
The patent implements feedback mechanisms where the system continuously evaluates the confidence level of geolocation data from different sources and adjusts its routing decisions accordingly. The confidence level assessment provides feedback on data reliability, allowing the system to maintain consistency by preferring high-confidence sources while adapting when better data becomes available.
3Measurement precision
If VoIP systems implement comprehensive geolocation tracking, then call routing accuracy is improved, but system complexity deteriorates
Solution Approach 1:
The system applies local quality by implementing geolocation tracking selectively based on routing needs rather than universally for all calls. The confidence level mechanism allows the system to focus computational resources on evaluating location data only when routing decisions require high precision, reducing overall system complexity while maintaining routing accuracy where needed.
Solution Approach 2:
The patent segments the geolocation determination process into distinct modular components: IP address database lookup, endpoint device GPS data collection, Wi-Fi network location data, and confidence level assessment. This segmentation allows each component to be independently managed and optimized, reducing system complexity while achieving comprehensive tracking capability.
4Reliability
If VoIP systems frequently update routing decisions based on location changes, then call quality is improved, but processing overhead deteriorates
Solution Approach 1:
The system implements periodic action by monitoring for trigger events such as endpoint device movement, IP address changes, or time-based intervals before updating routing decisions. This periodic monitoring approach allows the system to maintain call quality by responding to location changes while reducing processing overhead by not continuously evaluating routing options for every minor location variation.
Solution Approach 2:
The patent uses parameter changes by establishing confidence level thresholds that must be exceeded before triggering routing updates. This threshold-based approach allows the system to maintain reliability by updating routes only when location changes are significant enough to warrant the processing overhead, filtering out minor fluctuations that would otherwise consume resources.
Data Source
AI summary
A Voice over Internet Protocol (VoIP) server is configured to provide VoIP services to a plurality of VoIP-capable endpoint devices. At the VoIP server, a telephone call is received that involves a particular endpoint device of the plurality of VoIP-capable endpoint devices. A determination is made regarding the presence of a selectable routing option that is based upon a geographic location of the particular endpoint device. Geographic location information of the particular endpoint device is retrieved from a database. A confidence level for the geographic location information of the particular endpoint device is determined to be above a threshold level. A route for the telephone call is selected and used to complete the telephone call.
