Solution Overview

Problem

Users of mobile communication devices face difficulties in utilizing the most desirable current call placement options due to the constant changes and additions in call placement methods, leading to frustration among both users and system administrators.

Innovation Solution

Implementing a call destination mapping method on mobile communication devices that stores and applies call destination rules, including state conditions, to map call destination numbers sequentially through intermediate numbers, ensuring correct call routing based on device state and priority rules, with administration servers transmitting and managing these rules to ensure consistent and efficient call processing.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If multiple call placement options are constantly added and changed, then call placement versatility is improved, but user operation complexity increases

Engineering Contradiction:
Improvecall placement optionsVSAvoiduser difficulty
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The patent introduces an intermediary component (call processor or system administrator) that manages and controls the multiple call placement options. This intermediary handles the complexity of selecting and configuring the most desirable call placement option, shielding users from the complexity while maintaining versatility. The intermediary translates user intent into appropriate call placement actions without requiring users to understand the underlying complexity.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Adaptability or versatility

If users are provided with multiple call placement options, then system functionality is improved, but system administrator control difficulty increases

Engineering Contradiction:
Improvecall placement optionsVSAvoidadministrator control
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The patent implements feedback mechanisms where the system monitors and tracks which call placement options are most desirable based on usage patterns and performance metrics. This feedback information is provided to system administrators, enabling them to make informed decisions about which options to enable, disable, or modify. The feedback loop allows administrators to maintain control while supporting versatile call placement options.

Inventive Principle:
Principle #23Feedback

3Ease of operation

If call destination rules are made accessible to users, then user flexibility is improved, but rule management complexity increases

Engineering Contradiction:
Improveuser flexibilityVSAvoidrule management
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The patent implements a copying mechanism where simplified representations or copies of call destination rules are made available to users, rather than exposing the full complexity of the rule management system. Users can copy existing rules, modify them within limited parameters, and apply them without needing to understand the underlying rule structure. This maintains user flexibility while protecting the complexity of the rule management system.

Inventive Principle:
Principle #26Copying

AI summary

A call destination mapping method executes on a mobile communication device. The mobile communication device requests a call action within the device for a first call destination number of a call destination, maps the first call destination number to a second call destination number in accordance with one or more call destination mapping rules stored on the device, and replaces the first call destination number in the call action with the second call destination number.
