Terminal Registration Management via Solicitation Verification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication networks allow only single registration of a terminal with a network, leading to security vulnerabilities like identity theft and resource inefficiencies due to unauthorized multiple attachments, which are not addressed by current standards.
Innovation Solution
A method for managing multiple simultaneous registrations by verifying the validity of existing records and limiting the number of active registrations, using a management entity to ensure secure and efficient network resource allocation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a terminal is authorized to register multiple times simultaneously to a communication network, then network resource utilization and terminal connectivity are improved, but security risks such as identity theft and unauthorized access increase
Solution Approach 1:
The system performs preliminary validation by sending solicitation messages to verify the authenticity of each registration request before authorizing multiple attachments. This advance verification prevents unauthorized registrations while allowing legitimate multiple connections.
Solution Approach 2:
The management entity implements a feedback mechanism where it sends solicitation messages to registered terminals and processes their responses. This continuous verification ensures that all active registrations remain authentic and prevents identity theft by detecting unauthorized registrations.
2Reliability
If the network terminates previous registrations when a new terminal registers with the same IMSI, then authentication security is improved, but legitimate multiple simultaneous connections are blocked
Solution Approach 1:
Before terminating any existing registration, the system sends a solicitation message to verify the authenticity of the new registration request. This preliminary verification allows the network to distinguish between legitimate multiple attachments and unauthorized cloning, enabling both security and multiple connections.
Solution Approach 2:
Instead of automatically terminating previous registrations upon new registration (the conventional approach), the system inverts the logic by verifying the new request's authenticity first through solicitation messages. Only authenticated requests are allowed to proceed, transforming the automatic termination mechanism into a selective verification process.
3Reliability
If the network verifies authenticity of each registration request through solicitation messages, then security against identity theft is improved, but network signaling overhead and processing time increase
Solution Approach 1:
The system applies verification selectively rather than universally. Solicitation messages are sent only when needed to verify authenticity, not for every single registration attempt. This partial verification approach maintains security against identity theft while minimizing unnecessary signaling overhead and processing time.

AI summary
The invention relates to a method for registering a terminal (1a) with a communication network (Res), the method being implemented in a management entity (UDM) following the receiving (101) of a message requesting registration of the terminal (1a) with said network (Res), the management entity (UDM) comprising at least one prior registration of said terminal (1a) with said communication network (Res). The method comprises determining (102) a number of active registrations, from among the at least one prior registration, according to at least one received response message (104b) in response to at least one sent request message (103) which comprises at least one datum associated with the at least one prior registration, and updating (105) the at least one prior registration according to the received message (101) requesting registration in the case that the determined number of active registrations is smaller than a maximum number of registrations for said terminal.
