Dynamic Call Routing Based on Called Party Location

Resolve Bottlenecks,
Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing call forwarding systems are static and do not allow for dynamic redirection based on the location of the called party, limiting flexibility in managing calls.

Innovation Solution

A method and system that determine the location of the called party and apply location-dependent call processing rules to redirect calls to a second destination device, allowing for dynamic call management based on attributes and location.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If call forwarding uses a static destination, then the system is simple to operate, but the system lacks flexibility in managing calls based on location

Engineering Contradiction:

Improvecall management flexibilityVSAvoidcall forwarding system complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent transforms static call forwarding into a dynamic system by continuously monitoring the called party's location and automatically selecting different destination devices based on current location data. The call forwarding destination changes dynamically according to location-based rules rather than remaining fixed, resolving the contradiction between simplicity and flexibility.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The system changes the parameter of call forwarding destination from a static value to a dynamic value that varies based on location parameters. By introducing location as a variable parameter that influences call routing decisions, the system achieves greater adaptability while managing complexity through automated parameter adjustment.

Inventive Principle:

Principle #35Parameter changes

2Adaptability or versatility

If call forwarding is always active, then call management is automated, but the system cannot adapt to different locations and situations

Engineering Contradiction:

Improvelocation-based call handlingVSAvoidcall forwarding automation

Core Design Contradiction:

Adaptability or versatilityVSExtent of automation

Solution Approach 1:

The patent applies different call forwarding rules to different locations by creating location-specific routing configurations. Each location can have its own designated destination device and handling rules, allowing the system to adapt call management to local conditions while maintaining automated operation through location-based rule selection.

Inventive Principle:

Principle #3Local quality

Solution Approach 2:

The system performs preliminary actions by pre-configuring multiple call processing rules associated with different locations and destinations before actual call forwarding is needed. When a call arrives, the system automatically selects the appropriate pre-configured rule based on current location, enabling adaptive call handling without real-time manual intervention.

Inventive Principle:

Principle #10Preliminary action

AI summary

Call processing can include receiving a call directed to a first destination device associated with a called party, determining, using a processor, an attribute of the call, and determining a location of the called party. A call processing rule can be selected that matches the attribute of the call and the location of the called party. The call can be redirected to a second and different destination device according to the matched call processing rule.
