Communication Device Configuration via SIM Authentication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication device configuration methods, especially for LTE mobile devices and VoIP technology, are inefficient as they require manual delivery of unique numerical codes, leading to prolonged setup times and confusion in assigning identification keys, hindering immediate device activation and secure configuration.
Innovation Solution
A method where a communication device establishes a connection with an external configuration computer unit, using chip card-related identification features like IMSI and SuperPIN for authentication, allowing automatic configuration by matching transmitted data with stored data to retrieve and apply configuration settings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual delivery of unique numerical codes is used for configuration, then security and identification are improved, but setup time increases and immediate activation is hindered
Solution Approach 1:
The communication device performs self-identification using its built-in SIM card and automatic configuration through the configuration server, eliminating the need for manual code delivery and reducing setup time while maintaining security
Solution Approach 2:
The patent replaces the mechanical/manual delivery system of physical codes with an automated electronic system where the device automatically transmits identification data to the configuration server over a communication network
2Ease of operation
If standard SIM card identification features are used, then ease of operation is improved, but device complexity increases due to additional authentication requirements
Solution Approach 1:
The patent makes the SIM card serve multiple functions: both as a standard identification card for network authentication and as a source of configuration data for device setup, eliminating the need for separate configuration codes and simplifying user operation
Solution Approach 2:
The configuration server acts as an intermediary that automatically processes the identification data from the SIM card, retrieves corresponding configuration data, and transmits it to the device, handling the complex authentication and configuration matching process automatically
3Productivity
If automatic configuration via configuration server is implemented, then setup time is reduced, but security risks increase due to data transmission over networks
Solution Approach 1:
The patent extracts sensitive identification data (IMSI, PIN) from the SIM card for temporary transmission to the configuration server, but immediately after retrieval, the system closes the communication connection, minimizing the exposure window and reducing security risks
Solution Approach 2:
The system performs preliminary authentication using the SIM card data before any configuration data is transmitted, ensuring that only authorized devices can access configuration data and establishing security protocols in advance
