Solution Overview

Problem

Conventional portable devices face difficulties in maintaining seamless data communication when switching between different service operator networks due to inconsistencies in data communication settings, leading to potential errors and increased power consumption.

Innovation Solution

A method and apparatus for updating data communication settings based on Subscriber Identification Module (SIM) type, which extracts Mobile Country Code/Mobile Network Code (MCC/MNC) information to determine appropriate data communication settings from a policy table and establish connections with specific service operator networks, while implementing a fast dormancy policy to reduce power usage.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If data communication setting information is updated when switching between service operator networks, then data communication reliability is improved, but device complexity increases due to the need to manage multiple SIM types and policy tables

Engineering Contradiction:

Improvedata communication reliabilityVSAvoiddevice complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent segments data communication settings by SIM type, creating separate policy tables for different SIM categories (e.g., domestic SIM, roaming SIM, eSIM). This segmentation allows the device to manage complexity through organized categorization while maintaining reliable communication settings for each SIM type, directly resolving the contradiction between reliability improvement and device complexity.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent implements preliminary action by pre-configuring policy tables with data communication settings for various SIM types before actual communication occurs. When a SIM is detected, the system retrieves pre-prepared settings from the policy table, eliminating the need for real-time complex configuration decisions and reducing operational complexity while ensuring reliable communication.

Inventive Principle:

Principle #10Preliminary action

2Use of energy by moving object

If fast dormancy is applied during data communication setting updates, then power consumption is reduced, but communication latency may increase due to faster dormancy transitions

Engineering Contradiction:

Improvepower consumptionVSAvoidcommunication latency

Core Design Contradiction:

Use of energy by moving objectVSLoss of time

Solution Approach 1:

The patent applies dynamics by implementing adaptive fast dormancy that adjusts its behavior based on communication conditions. The system dynamically decides when to apply fast dormancy transitions and when to maintain connection, optimizing the balance between power consumption and latency based on real-time network status and traffic patterns.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The patent changes parameters of the fast dormancy mechanism based on SIM type and network conditions. Different dormancy thresholds and transition timings are configured for different SIM categories, allowing the system to optimize power consumption without excessive latency penalty by adjusting parameters to match actual communication needs.

Inventive Principle:

Principle #35Parameter changes

3Reliability

If data communication settings are customized for each SIM type, then communication quality is improved, but ease of operation deteriorates due to increased configuration complexity

Engineering Contradiction:

Improvecommunication qualityVSAvoidease of operation

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The patent implements self-service by having the device automatically detect SIM type and retrieve corresponding settings from the policy table without user intervention. The system autonomously manages SIM-type-specific configurations, maintaining high communication quality while preserving ease of operation as users simply insert SIM cards without manual configuration.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The patent creates a universal policy table structure that handles multiple SIM types through a single unified mechanism. The same policy table infrastructure serves domestic SIMs, roaming SIMs, and eSIMs, providing customized settings for each type while maintaining a simple, unified system architecture that preserves ease of operation.

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

A method and a portable device that support the control of a data communication setting are provided. The portable terminal includes a Subscriber Identification Module (SIM) card interface into which the SIM is inserted. The device further includes a control unit, a memory unit, and a radio frequency unit. The control unit extracts Mobile Country Code/Mobile Network Code (MCC/MNC) information from the inserted SIM, determines data communication setting information corresponding to the MCC/MNC information from a policy table containing the data communication setting information for each MCC/MNC information, and establishes a data communication by using the determined data communication setting information. The memory unit stores the policy table, and the radio frequency unit performs the established data communication with a specific service operator network related to the SIM under the control of the control unit.
