Solution Overview

Problem

Conventional portable electronic devices configured for GPRS packet data communications automatically attach to the network upon power up, occupying network resources even if the device rarely uses packet data capabilities, leading to limited network traffic and user inconvenience.

Innovation Solution

The portable electronic device includes a transmitter and an attaching circuit that requests a packet data session, collects information about the session, and determines default parameters to customize network attachment, such as auto-attach settings based on usage patterns, to optimize network attachment and detachment.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If automatic network attachment is enabled upon power up, then user convenience is improved, but network resource occupation increases for devices that rarely use packet data

Engineering Contradiction:

Improveuser convenienceVSAvoidnetwork resource occupation

Core Design Contradiction:

Ease of operationVSQuantity of substance

Solution Approach 1:

The patent implements dynamic network attachment parameters that adapt based on actual usage patterns. The system monitors packet data usage frequency and automatically adjusts attachment behavior - devices that frequently use packet data remain attached, while those that rarely use it detach to free network resources. This dynamic adaptation resolves the contradiction by making attachment status flexible rather than static.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The patent changes the attachment parameter state based on usage analysis. By monitoring whether a device actually utilizes packet data services over time, the system modifies the auto-attach parameter - enabling it for high-usage devices and disabling it for low-usage devices. This parameter change strategy optimizes both user convenience and network resource allocation.

Inventive Principle:

Principle #35Parameter changes

2Quantity of substance

If automatic network attachment is disabled, then network resource occupation is reduced, but user convenience deteriorates due to attachment delay

Engineering Contradiction:

Improvenetwork resource occupationVSAvoiduser convenience

Core Design Contradiction:

Quantity of substanceVSEase of operation

Solution Approach 1:

The patent performs preliminary analysis of device usage patterns to determine the optimal attachment strategy before actual network operations. By pre-configuring attachment behavior based on historical usage data, the system ensures that devices are attached in advance when packet data usage is anticipated, eliminating delays while preventing unnecessary network occupation for devices with low usage patterns.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The patent implements a feedback mechanism that continuously monitors packet data usage and adjusts attachment parameters accordingly. When usage patterns indicate a device will need packet data services, the system proactively maintains or establishes attachment, ensuring user convenience is not compromised. This feedback loop resolves the contradiction by making attachment status responsive to actual network needs.

Inventive Principle:

Principle #23Feedback

3Device complexity

If uniform auto-attach parameter is applied to all devices, then device complexity is minimized, but network efficiency deteriorates due to unused bandwidth allocation

Engineering Contradiction:

Improveparameter uniformityVSAvoidnetwork efficiency

Core Design Contradiction:

Device complexityVSProductivity

Solution Approach 1:

The patent applies local quality by customizing attachment parameters for individual devices based on their specific usage patterns rather than applying a uniform setting to all devices. Each device receives a tailored attachment strategy - some devices get auto-attach enabled while others get it disabled - based on their local characteristics and actual packet data usage behavior. This local customization optimizes network efficiency without significantly increasing device complexity.

Inventive Principle:

Principle #3Local quality

Solution Approach 2:

The patent segments the device population into different groups based on packet data usage patterns. By dividing devices into high-usage and low-usage segments, the system can apply different attachment strategies to each segment, improving overall network efficiency. This segmentation approach allows differentiated parameter settings without requiring complex individual configurations for each device.

Inventive Principle:

Principle #1Segmentation
