Solution Overview

Problem

Conventional solutions for redialing conference calls on portable devices require users to manually re-enter conference call information, wasting time and processing resources, and are inefficient when the call details are not pre-programmed.

Innovation Solution

A wireless device with a calling module that monitors dialled numbers after establishing a call connection, determines if they meet predetermined criteria, and saves them for automatic redialing if the call is dropped, thereby eliminating the need for manual re-entry.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If users manually re-enter conference call information after a dropped call, then the call can be re-established, but user time and processing resources are wasted

Engineering Contradiction:
Improvecall re-establishmentVSAvoiduser time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The system performs preliminary action by automatically storing the conference call information (first dialled number and subsequent numbers) in memory during the initial call setup. When a call is dropped, this pre-stored information is automatically retrieved and used to re-establish the call without requiring user re-entry, thus resolving the contradiction between reliable call re-establishment and time loss.

Inventive Principle:
Principle #10Preliminary action

2Reliability

If users manually re-enter conference call information, then the call can be re-established, but processing resources and battery power are wasted

Engineering Contradiction:
Improvecall re-establishmentVSAvoidbattery power
Core Design Contradiction:
ReliabilityVSUse of energy by moving object

Solution Approach 1:

The system creates a copy of the conference call information (dialled numbers) and stores it in memory during the initial call setup. When the call is dropped, this copied information is automatically retrieved and used to re-establish the call, eliminating the need for users to re-enter the information and thus conserving battery power while ensuring reliable call re-establishment.

Inventive Principle:
Principle #26Copying

3Adaptability or versatility

If conference call information is not pre-programmed, then the device is more adaptable, but users must re-enter information manually

Engineering Contradiction:
Improvedevice adaptabilityVSAvoiduser operation
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The system implements self-service by automatically detecting when conference call information is being entered, storing it in memory, and automatically retrieving and re-entering it when a call is dropped. This eliminates the need for users to manually re-enter information, making the device both adaptable to different conference calls and easy to operate, thus resolving the contradiction between adaptability and ease of operation.

Inventive Principle:
Principle #25Self-service

AI summary

A wireless device (102) and method are provided for redialling of conference calls comprising: establishing a call connection based on a first dialled number (502); monitoring for subsequent numbers dialled after the establishment of the call connection (504); determining if the subsequent numbers dialled meet predetermined criteria (506); and saving the first dialled number and the subsequent numbers dialled in a memory of the wireless device as a saved first dialled number and saved subsequent numbers if the predetermined criteria are met (508).
