Solution Overview

Problem

In the context of LTE networks, N11 code calls are often routed to the home cellular network instead of the local phone system, leading to incorrect routing and provision of information for the wrong local area when the caller is not at their residence or the service provider's central location.

Innovation Solution

A location-based call rerouting system that includes a visitor cellular network, a local phone system, a home cellular network, and a location-based routing platform, which uses registration data to determine the caller's geographic location and reroute N11 code calls to the correct local phone system, ensuring accurate service provision.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If N11 code calls are routed through the home cellular network in LTE systems, then call routing is simplified and home network control is maintained, but the calls are routed to the wrong local phone system when callers are outside their home area

Engineering Contradiction:
Improvecall routing complexityVSAvoidcaller location accuracy
Core Design Contradiction:
Device complexityVSMeasurement precision

Solution Approach 1:

A location-based routing platform is introduced as an intermediary between the home cellular network and the local phone system. This platform receives registration data from the home network, determines the caller's actual geographic location, and routes N11 code calls to the correct local phone system, thereby resolving the contradiction between simplified routing and accurate location-based routing

Inventive Principle:
Principle #24Intermediary (Mediator)

2Ease of operation

If calls are routed based on home network registration, then network management is easier, but location-based services provide incorrect information when users are traveling

Engineering Contradiction:
Improvenetwork management easeVSAvoidlocal area information accuracy
Core Design Contradiction:
Ease of operationVSLoss of information

Solution Approach 1:

The system performs preliminary location determination by receiving registration data from the home cellular network before routing the N11 code call. The location-based routing platform uses this registration data to proactively identify the caller's current geographic location and pre-determine the appropriate local phone system, ensuring accurate local information is provided while maintaining ease of network management

Inventive Principle:
Principle #10Preliminary action

AI summary

A method, system, apparatus, and/or device for rerouting a location-based phone call. The method, system, apparatus, and/or device may include a home cellular network and a location-based routing platform. The home cellular network may be configured to receive registration data indicating a cellular tower communicatively coupled with a cellular device, receive a location-based telephone call from the cellular device, and send the registration data to a location-based routing platform. The location-based routing platform may be configured to receive the registration data from the home cellular network, determine a location of the cellular device, and send a redirection request to the home cellular network for the home cellular network to redirect the location-based telephone call to a local phone system associated with the location of the cellular device, where the home cellular network is configured to redirect the location-based telephone call to the local phone system.
