Memory Module Activation Across Multiple Networks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for activating and managing memory modules on telecommunications terminals are complex and require substantial modifications to both the memory modules and network architecture, making it difficult to seamlessly switch between networks and manage subscriptions across multiple countries.
Innovation Solution
A method that authenticates a memory module with a central database via an interconnection gateway, allowing a single type of memory module to be recognized across multiple networks, enabling activation and management without the need for pre-loading sensitive data, and allowing terminals to switch from roaming to local traffic.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single type of memory module is used across multiple networks, then device complexity is reduced and manufacturing is simplified, but the ability to authenticate and activate on different networks becomes more difficult
Solution Approach 1:
The solution segments the identification data into two parts: a permanent manufacturer identifier stored in the memory module, and a temporary network-specific identifier stored in the terminal. This allows the same memory module to work across different networks by switching the temporary identifier, resolving the contradiction between standardization and adaptability.
Solution Approach 2:
The system changes the parameter of identification data by switching between a permanent manufacturer identifier and a temporary network identifier. This parameter switching enables the same memory module to be authenticated on different networks without requiring multiple hardware types.
2Adaptability or versatility
If sensitive data is pre-loaded on terminals for multiple networks, then activation on multiple networks is enabled, but security risks increase and the process becomes tedious
Solution Approach 1:
The solution extracts the sensitive authentication data from the terminal and stores it securely in the network's database. The terminal only keeps a non-sensitive temporary identifier, which is used to retrieve the actual authentication credentials from the database during activation, eliminating the need to pre-load sensitive data on the terminal.
Solution Approach 2:
The system introduces a temporary identifier as an intermediary between the terminal and the sensitive authentication data. This temporary identifier is stored in the terminal and used to access the actual credentials in the database, allowing multi-network activation without exposing sensitive data on the terminal.
3Adaptability or versatility
If terminals are distributed in several countries with different network subscriptions, then local service access is enabled, but the activation process becomes complex and requires modifications for each country
Solution Approach 1:
The solution makes the memory module universal by storing only the manufacturer identifier, which is recognized by all networks. The network-specific activation is handled through a standardized process involving a temporary identifier and database lookup, allowing the same hardware to function across different countries without modifications.
Solution Approach 2:
The system enables self-service activation where the terminal automatically retrieves its authentication credentials from the database using its temporary identifier, without requiring manual configuration or complex activation procedures for each country.
4Reliability
If existing network architecture is modified to support memory module authentication, then network control is improved, but implementation complexity and cost increase
Solution Approach 1:
The system performs preliminary actions by storing the manufacturer identifier in the memory module during manufacturing and pre-configuring the database with device credentials. This allows the network to authenticate devices using a standardized process without requiring complex real-time modifications to the network architecture.
