Solution Overview

Problem

The existing methods for providing operator-specific information to SIM cards are inefficient, requiring retailers to stock and manage multiple SIM cards from different operators, and the Machine Communication Identity Module (MCIM) has not gained widespread use due to high handling costs.

Innovation Solution

A method for provisioning network information into a subscriber identity module within a user device, where the information is configured based on the device's capabilities and can be received in various formats such as text, RFID tags, or barcodes, allowing dynamic configuration and elimination of the need for physical SIM cards.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If operator-specific SIM cards are manufactured and stocked by retailers, then each SIM card can be immediately used with its corresponding operator, but retailers incur high handling costs and complexity from managing multiple operator-specific SIM cards

Engineering Contradiction:
ImproveSIM card usage with operatorVSAvoidRetailer management of multiple SIM cards
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The SIM card is designed to be universal and operator-agnostic, capable of working with multiple operators through dynamic provisioning. The SIM card can be configured remotely to support different operators, eliminating the need for retailers to stock multiple operator-specific SIM cards while maintaining the ability to connect to the correct operator network.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The SIM card is pre-configured with the capability to receive operator-specific information through remote provisioning. The infrastructure for dynamic configuration is established in advance, allowing the SIM card to be activated for specific operators after issuance without requiring physical reconfiguration or manufacturer intervention.

Inventive Principle:
Principle #10Preliminary action

2Reliability

If multiple operator-specific SIM cards are manufactured, then each SIM card is optimized for its specific operator, but the manufacturing and distribution process becomes complex and costly

Engineering Contradiction:
ImproveSIM card connection to operatorVSAvoidSIM card production and distribution
Core Design Contradiction:
ReliabilityVSEase of manufacture

Solution Approach 1:

The SIM card functionality is segmented into two parts: a universal base configuration that works with multiple operators, and operator-specific parameters that are dynamically provisioned remotely. This separation allows standardized manufacturing of the universal SIM card while enabling flexible, on-demand configuration for different operators through electronic provisioning.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

A remote provisioning system acts as an intermediary between SIM card manufacturers and operators. This intermediary infrastructure enables the distribution of operator-specific information electronically, eliminating the need for complex coordinated manufacturing processes between multiple manufacturers and operators while ensuring reliable SIM card activation.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Extent of automation

If MCIM is used for machine-to-machine authentication, then credential management is automated, but handling costs remain high due to the specialized infrastructure required

Engineering Contradiction:
ImproveM2ME authenticationVSAvoidMCIM infrastructure
Core Design Contradiction:
Extent of automationVSDevice complexity

Solution Approach 1:

The SIM card is designed to provide universal authentication capabilities that can serve both traditional mobile subscriptions and machine-to-machine communications. By using the existing SIM card infrastructure with remote provisioning, the system achieves automated credential management for M2ME without requiring the specialized MCIM infrastructure, thereby reducing complexity while maintaining automation.

Inventive Principle:
Principle #6Universality (Multi-functionality)
