Solution Overview

Problem

The traditional SIM card provisioning process is prone to errors and inefficiencies, with CPS files sometimes being lost or not delivered to the OTA platform, leading to failed OTA operations and requiring costly manual intervention.

Innovation Solution

An automated provisioning application resident on the SIM card sends a provisioning request to the OTA platform when first used, including IMSI, ICCID, and OTA keys, which updates the database and retrieves MSISDN, enabling automated activation and reducing manual intervention.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If CPS files are manually transferred to the OTA platform, then the SIM card can be activated, but the process is time-consuming and error-prone

Engineering Contradiction:
Improveprovisioning success rateVSAvoidprovisioning time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The SIM card is equipped with an automated provisioning application that enables it to self-provision by automatically sending its own identification data (ICCID, IMSI) to the OTA platform when first inserted into a mobile device, eliminating the need for manual CPS file transfer and reducing both time and errors

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The SIM card is pre-configured with an automated provisioning application during manufacturing that prepares the card to automatically initiate the provisioning process itself when first used, rather than requiring pre-provisioning through manual CPS file transfer

Inventive Principle:
Principle #10Preliminary action

2Ease of manufacture

If manual intervention is used in the provisioning process, then complex operations can be performed, but costs increase

Engineering Contradiction:
Improveprovisioning flexibilityVSAvoidprovisioning efficiency
Core Design Contradiction:
Ease of manufactureVSProductivity

Solution Approach 1:

The automated provisioning application on the SIM card performs the provisioning operations autonomously, eliminating costly manual intervention while maintaining the ability to handle complex provisioning scenarios through automated logic

Inventive Principle:
Principle #25Self-service

3Reliability

If CPS files are used for provisioning, then SIM card activation is possible, but files may be lost or not delivered

Engineering Contradiction:
Improvedata delivery reliabilityVSAvoidprovisioning system complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The critical provisioning data (ICCID, IMSI) is extracted from the SIM card and sent directly to the OTA platform by the automated application, eliminating the intermediary CPS file transfer step that is prone to loss or delivery failures

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The automated provisioning application on the SIM card acts as an intermediary that directly communicates the necessary identification data to the OTA platform, replacing the CPS file as the intermediary carrier and ensuring reliable data delivery

Inventive Principle:
Principle #24Intermediary (Mediator)

AI summary

Method of automatic provisioning of a SIM card (2) when using the SIM card for the first time by means of an OTA (Over-The- Air) platform (1) and a mobile telephone (8). The method is characterized in, that equipping the SIM card (2) with an automated provisioning application (3) that be- comes resident on the SIM card (2), in that activation data comprising IMSI and other data is being stored on the SIM card, in that the SIM card (1) is caused to send a provision- ing request, when the SIM card is placed in a mobile tele- phone (8) for the first time and the telephone is switched on, to the OTA platform (1), in that a database (7) asso- ciated with the OTA platform (1) is updated with data includ- ing ICCID, IMSI and OTA keys, in that the OTA platform (1) retrieves MSISDN from the data sent to the OTA platform and in that the MSISDN is attached to said IMSI.
