Solution Overview

Problem

Current mobile apparatuses face limitations when switching between networks, particularly when roaming, with restricted services, higher charges, and complex billing mechanisms, limiting flexibility and service quality for users and operators.

Innovation Solution

A mobile apparatus equipped with multiple parameter data sets, each containing geographic tags and connection parameters, allows for automatic or user-driven selection of the most suitable network, enabling direct connections and customizable service options, independent of roaming agreements.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a mobile apparatus uses roaming agreements to access foreign networks, then international service coverage is improved, but service quality is limited and charges are higher

Engineering Contradiction:

Improveinternational service coverageVSAvoidservice quality

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The SIM card is segmented to contain multiple independent parameter data sets, each configured for a different home network. This allows the mobile apparatus to switch between different network configurations based on geographic location, enabling direct connection to foreign networks as if they were home networks, thereby improving service quality without relying on roaming agreements.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The system changes network connection parameters dynamically by selecting different parameter data sets stored in the SIM card. Each data set contains network-specific parameters for a particular geographic region, allowing the mobile apparatus to adapt its connection parameters to match the local network, thus achieving direct connection and improved service quality in different countries.

Inventive Principle:

Principle #35Parameter changes

2Adaptability or versatility

If a mobile apparatus uses roaming agreements to access foreign networks, then international service coverage is improved, but service charges increase

Engineering Contradiction:

Improveinternational service coverageVSAvoidservice cost

Core Design Contradiction:

Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The system performs preliminary configuration by pre-storing multiple network parameter data sets in the SIM card before the user travels. Each data set is prepared in advance for a specific geographic region, allowing the mobile apparatus to immediately connect to the appropriate network upon arrival without incurring roaming charges, thus reducing service costs internationally.

Inventive Principle:

Principle #10Preliminary action

3Adaptability or versatility

If a mobile apparatus stores multiple parameter data sets in the SIM card, then network selection flexibility is improved, but device complexity increases

Engineering Contradiction:

Improvenetwork selection flexibilityVSAvoidSIM card structure

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The SIM card is designed with multi-functionality to store and manage multiple parameter data sets for different home networks. This universal SIM card can adapt to various network configurations and geographic locations, providing network selection flexibility without requiring multiple separate SIM cards or complex external configuration systems, thus managing device complexity effectively.

Inventive Principle:

Principle #6Universality (Multi-functionality)

4Ease of operation

If a mobile apparatus automatically selects networks based on geographic location, then ease of operation is improved, but loss of information increases due to routing through home network

Engineering Contradiction:

Improveautomatic network selectionVSAvoiddata communication efficiency

Core Design Contradiction:

Ease of operationVSLoss of information

Solution Approach 1:

Inventive Principle:

Principle #10Preliminary action

AI summary

A method is provided for selecting an available network (10) by a mobile apparatus (20), such as a mobile phone. As a subscriber moves from country to country he needs to switch from network to network, with limited control over the network chosen and the services provided by the network. The mobile phone (20) is provided with more than parameter sets (50), providing connection parameters (52) for more than one network based upon the geographic location (70,80,90) that the mobile phone (20) is in. The mobile phone (20) may provide for automatic selection of the available network (10).
