Digital User Identifier Binding in 5G Mobile Networks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In 5G mobile communication systems, service providers face challenges in uniquely identifying users subscribing to their services without exposing personal information, especially when using conventional identifiers like SUPI or IP addresses, which may not be suitable due to exposure risks or lack of uniqueness.
Innovation Solution
A method and device for mobile binding that involves receiving provisioning information, verifying a digital user identifier through user authentication, and binding it with subscriber information in a database, allowing the service provider to uniquely identify users using a digital user identifier without exposing personal information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional identifiers like SUPI or IP addresses are used for user identification, then user identification can be performed, but personal information exposure risks increase and uniqueness cannot be ensured
Solution Approach 1:
The patent introduces a digital user identifier as an intermediary that mediates between the user and the service provider. This digital identifier acts as a mediator that allows service providers to identify users without direct access to personal information such as SUPI or IP addresses, thereby resolving the contradiction between reliable identification and information exposure protection
Solution Approach 2:
The patent creates a digital copy or representation of the user identifier that can be used for service identification purposes. This digital user identifier is a copy that fulfills the identification function without requiring exposure of the original personal information, thus protecting user privacy while maintaining identification reliability
2Object-affected harmful factors
If digital user identifier binding is implemented, then personal information protection is improved, but system complexity increases due to additional binding and verification processes
Solution Approach 1:
The patent performs the binding of the digital user identifier with subscriber information in advance, during the initial authentication phase. This preliminary action ensures that the binding is already established before service delivery begins, eliminating the need for complex real-time binding operations and reducing overall system complexity while maintaining security
Solution Approach 2:
The binding process is integrated into the existing authentication workflow, allowing the system to automatically perform binding operations as part of the standard authentication process. This self-service approach eliminates the need for separate manual binding procedures, reducing operational complexity while ensuring personal information protection

AI summary
Disclosed is a method and device for binding a user and a UE in a mobile communication system. A method by a network entity may comprise receiving provisioning information for a user from a service provider, receiving a binding request message including verification information and a digital user identifier from a user equipment completing user authentication for the service provider, verifying the verification information using the provisioning information, and the verification information being successfully verified, binding the digital user identifier with the UE's subscriber information and storing in a subscriber database. The subscriber database may be used to provide a service corresponding to a service invocation to the UE in response to receiving the service invocation including the digital user identifier from the service provider.
