Solution Overview

Problem

Users of handheld communication devices face limited control over available communication services, often unknowingly switching between billable and non-billable networks or high-speed and low-speed connections, leading to unexpected service usage.

Innovation Solution

A method for a handheld communication device to determine available communication services without opening a traffic channel, providing users with real-time indications of service availability through visual, tactile, or audio notifications, using service authorization and communication mode indication procedures.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If the device automatically switches between communication services without user notification, then the device maintains seamless connectivity and automatic service selection, but the user loses control and awareness of which network is being used, leading to unexpected billable service usage

Engineering Contradiction:
Improveseamless connectivityVSAvoiduser awareness of active service
Core Design Contradiction:
ProductivityVSLoss of information

Solution Approach 1:

The patent implements a feedback mechanism by displaying icons on the device interface that indicate which communication service is currently active. This visual feedback allows users to monitor network usage in real-time while the device automatically manages service switching, resolving the contradiction between automatic operation and user awareness.

Inventive Principle:
Principle #23Feedback

2Loss of information

If the device provides detailed service status information to users, then users gain awareness and control over communication services, but the device complexity and information processing requirements increase

Engineering Contradiction:
Improveservice status transparencyVSAvoidinformation processing complexity
Core Design Contradiction:
Loss of informationVSDevice complexity

Solution Approach 1:

The patent uses different icons or icon variations to represent different communication services and their status. This visual encoding method provides comprehensive service information to users in a simple, intuitive manner without requiring complex data processing or display mechanisms, thus resolving the contradiction between information transparency and device complexity.

Inventive Principle:
Principle #32Color changes

3Measurement precision

If the device monitors and detects available communication services continuously, then the device can provide accurate service availability information to users, but the energy consumption and processing overhead increase

Engineering Contradiction:
Improveservice availability detection accuracyVSAvoidenergy consumption for service detection
Core Design Contradiction:
Measurement precisionVSUse of energy by moving object

Solution Approach 1:

The patent implements periodic service detection rather than continuous monitoring. The device checks for available communication services at regular intervals and updates the displayed icons accordingly. This periodic approach maintains accurate service availability information while significantly reducing energy consumption compared to continuous monitoring, resolving the identified contradiction.

Inventive Principle:
Principle #19Periodic action

AI summary

A method of indicating the availability of a communication service begins by receiving, at a handheld communication device, a service indication of an availability of one of a plurality of communication services, via a wireless communication mode, to the communication device. The handheld communication device receives the service indication from a provider of the one communication service via a wireless non-traffic channel of the wireless communication mode. The communication device then provides a user-indication of the communication service availabilities in accordance with the received service indication.
