Network Server IMSI to MSISDN Mapping for Secure User Recognition
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for user recognition in networks, especially when accessing through Wi-Fi, are time-consuming and require users to manually input PIN codes, making them inefficient and unpopular.
Innovation Solution
A method involving two servers and identifiers (IMSI and MSISDN) that allows user profile recognition without requiring users to input their telephone number or receive PIN codes, using a first server to map IMSI to MSISDN and generate a One Time Password for secure confirmation, reducing user intervention and optimizing network resources.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If users manually input PIN codes for authentication, then user recognition is achieved, but the process becomes time-consuming and inefficient
Solution Approach 1:
The system performs preliminary actions by automatically obtaining the IMSI from the user device and mapping it to the MSISDN in advance, before the user needs to be authenticated. This pre-processing eliminates the need for manual PIN input during actual authentication, reducing time loss while maintaining recognition accuracy
Solution Approach 2:
The authentication system serves itself by automatically extracting the IMSI from the user device and retrieving the MSISDN through the HLR without requiring user intervention. The system performs the recognition process autonomously, eliminating the time-consuming manual PIN entry step while ensuring accurate user identification
2Reliability
If SMS with PIN code is sent to user, then authentication is enabled, but network traffic increases and user intervention is required
Solution Approach 1:
The invention extracts only the essential authentication information (IMSI and MSISDN mapping) from the complex SMS-based authentication process. By removing the PIN code transmission step and using direct IMSI-to-MSISDN mapping, the system maintains security while significantly reducing network traffic volume
Solution Approach 2:
The HLR acts as an intermediary that automatically performs the mapping between IMSI and MSISDN without requiring SMS communication. This intermediary approach eliminates the need for PIN code transmission through SMS, reducing network traffic while maintaining authentication security
3Reliability
If user profile recognition is implemented on Wi-Fi network, then user identification is achieved, but the process becomes complex and requires multiple steps
Solution Approach 1:
The system achieves universal user recognition across different network types (mobile and Wi-Fi) by using the same IMSI-based approach. The first server performs multi-functional operations: obtaining IMSI, mapping to MSISDN, and enabling recognition on both mobile and Wi-Fi networks, thereby simplifying the overall process complexity while maintaining identification accuracy
Solution Approach 2:
The invention merges the user recognition process into a single unified flow where the first server handles all operations (IMSI extraction, MSISDN mapping, and authentication) in sequence. This consolidation eliminates the need for separate authentication steps for different network types, reducing process complexity while ensuring accurate user identification

AI summary
There is provided a method for recognizing a user profile associated to a subscriber identity module (SIM) by a first server located in network, wherein the user profile operates on a user device (UD) and wherein the method comprises the steps of: sending a first identifier (IMSI), by the user device (UD), to the first server; obtaining an identity of a second server, by the first server, associated to the first identifier (IMSI); requesting to the second server, by the first server, a second identifier (MSISDN) associated to the user profile; receiving the second identifier (MSISDN) by the first server; recognizing, by the first server, the user profile associated to the second identifier (MSISDN). There is also provided a user device program, a user device, a computer program and a first server.
