Subscriber Registration Management in Mobile Networks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mobile communication networks face issues with double registration of subscribers in multiple registers, leading to resource mismanagement and signaling disruptions, particularly during traffic bursts or network breaks.
Innovation Solution
A method and system that involves obtaining information from multiple subscriber registers at different times to determine if a subscriber is registered, and if so, generating a message to cancel the registration across all affected registers, ensuring accurate and efficient management of subscriber information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the mobility management entity dismisses signaling messages to release resources during traffic burst situations, then resource utilization is improved, but subscriber registration reliability deteriorates causing double registration
Solution Approach 1:
The system implements a feedback mechanism where the mobility management entity monitors subscriber registration status across multiple registers. When double registration is detected through location update procedures, the system generates cancel location messages to remove duplicate registrations, ensuring registration reliability while allowing resource dismissal during traffic bursts
Solution Approach 2:
The system performs preliminary checks during location update procedures to detect potential double registrations before they cause problems. By proactively identifying and canceling duplicate registrations through location update messages and responses, the system prevents registration conflicts while maintaining efficient resource utilization
2Reliability
If the system maintains accurate subscriber registration information across multiple registers, then registration reliability is improved, but signaling network complexity increases
Solution Approach 1:
The system extracts and monitors only the critical registration status information from multiple registers through location update procedures. By focusing on essential data (subscriber identity and registration status) rather than all register contents, the system maintains registration accuracy while minimizing signaling network complexity
Solution Approach 2:
The mobility management entity acts as an intermediary that coordinates registration information across multiple registers. It receives location update messages, processes registration status, and generates appropriate cancel location messages, simplifying the overall signaling network architecture while ensuring accurate subscriber management
3Measurement precision
If the system performs frequent location update procedures to detect double registration, then registration accuracy is improved, but network signaling load increases
Solution Approach 1:
The system performs location update procedures selectively rather than continuously - only when triggered by specific events such as subscriber movement or potential double registration scenarios. This partial action approach maintains detection accuracy for registration status while significantly reducing overall network signaling load compared to continuous monitoring

AI summary
The invention relates to a solution for managing subscriber information in a mobile communication network. In the solution information on a subscriber (140) is obtained and inquiries are generated to a plurality of subscriber registers (126; 136) at a plurality of instants of time. The inquiries are performed in order to determine (260) if the subscriber (140) is registered in the subscriber registers (126; 136) at the instants of time. If this is the case a message is generated (270) for canceling (270) the registration of the subscriber (140) in subscriber registers (126; 136). The solution is based on a method, a network node (124; 134), a computer program code and a system.
