Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Current communication systems face challenges in uniquely identifying endpoints in private networks using limited public IP addresses, particularly in VoIP environments, where network address translation (NAT) is employed but lacks efficient control over caller IDs and location-based routing.

Innovation Solution

A telecommunications-providing server system that dynamically adjusts caller IDs and routes VoIP calls based on client-specific data, using a region-based NAT and analog-telephone bridging to connect endpoints across private and public networks, allowing for revised caller IDs that reflect the geographic location of endpoints and enabling seamless communication with emergency services.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Quantity of substance

If network address translation (NAT) is used to allow multiple endpoints in a private network to communicate using a single public IP address, then the number of endpoints that can be identified increases, but control over caller IDs and location-based routing is lost

Engineering Contradiction:

Improvenumber of endpointsVSAvoidcontrol over caller IDs

Core Design Contradiction:

Quantity of substanceVSEase of operation

Solution Approach 1:

The system segments the single public IP address into multiple virtual ports, where each port is associated with specific caller ID and geographic region information. This allows multiple endpoints to be identified while maintaining control over caller IDs through port-based segmentation.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The telecommunications-providing server acts as an intermediary between the NAT circuit and endpoints, receiving caller ID information from the NAT circuit and selectively revising it based on geographic region and client-specific data before forwarding to the called endpoint.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Adaptability or versatility

If traditional NAT is used for address translation, then public IP address limitation is addressed, but location-based services and emergency service connectivity are compromised

Engineering Contradiction:

Improveaddress translation capabilityVSAvoidemergency service connectivity

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The system performs preliminary actions by determining the geographic region of the called endpoint before completing the call connection, and selectively revises the caller ID to ensure proper routing to emergency services based on location information.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system changes the caller ID parameter dynamically based on the geographic region and client-specific data, ensuring that emergency services receive calls with appropriate location information while maintaining address translation functionality.

Inventive Principle:

Principle #35Parameter changes

3Measurement precision

If caller IDs are revised to reflect geographic location, then location-based services are improved, but system complexity increases

Engineering Contradiction:

Improvelocation accuracyVSAvoidsystem complexity

Core Design Contradiction:

Measurement precisionVSDevice complexity

Solution Approach 1:

The system enables self-service by allowing client entities to provide their own client-specific data sets that contain geographic region information and routing rules, reducing the burden on the telecommunications-providing server to maintain complex location databases.

Inventive Principle:

Principle #25Self-service

4Productivity

If region-based NAT is implemented with client-specific control, then routing efficiency is improved, but device complexity increases

Engineering Contradiction:

Improverouting efficiencyVSAvoidserver complexity

Core Design Contradiction:

ProductivityVSDevice complexity

Solution Approach 1:

The telecommunications-providing server performs multiple functions including receiving data packets, determining geographic regions, revising caller IDs, and routing calls, consolidating these functions into a single multi-functional system that improves routing efficiency while managing complexity centrally.

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

Systems and methods are disclosed for client-based control of revising caller identifications (IDs) for communications between a private network and a public network. An apparatus including a communications provider server and processing circuit that communicates client-specific sets of data over an interface protocol. The telecommunications-providing server revises a caller ID for a data communication (aka call) based on the client-specific sets of data, an identifier that corresponds to a requesting endpoint, and a geographic region determined from the call request. Further, the telecommunications-providing server connects the VoIP call by accessing and passing a provisioned number. The provisioned number includes the revised caller ID which is a local number identified by the determined geographic region that the endpoint is located.
