Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current telecommunications networks face challenges in synchronizing supplementary service settings across different generations of networks, leading to inefficiencies and errors in service establishment and modification for user equipment, particularly between 5G, LTE, and 2G/3G networks.
Innovation Solution
A synchronization server is utilized to replicate and synchronize supplementary service settings between Unified Data Management (UDM), Home Subscriber Server (HSS), and Home Location Register (HLR) nodes, ensuring consistent data storage and reducing manual intervention and errors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If supplementary service settings are manually managed across different network nodes (UDM, HSS, HLR), then service establishment can be performed, but synchronization errors and manual intervention requirements increase
Solution Approach 1:
A synchronization server is introduced as an intermediary component that automatically synchronizes supplementary service settings between UDM, HSS, and HLR nodes. The synchronization server receives settings from UDM and distributes them to HSS and HLR, eliminating manual intervention and ensuring consistent data across all network nodes, thereby improving reliability while reducing operational complexity
Solution Approach 2:
The system implements automated self-service synchronization where the synchronization server autonomously manages the distribution and updating of supplementary service settings across network nodes without requiring manual configuration. The system automatically detects changes and propagates them, reducing the need for human intervention and minimizing synchronization errors
2Adaptability or versatility
If supplementary service settings are stored in multiple network nodes (UDM, HSS, HLR), then service availability is improved, but data consistency and synchronization between nodes become problematic
Solution Approach 1:
The synchronization server acts as a central mediator that maintains data consistency across distributed nodes. It receives supplementary service settings from UDM and ensures identical data is propagated to HSS and HLR, preventing data loss and inconsistency while allowing the system to leverage multiple nodes for improved service availability
Solution Approach 2:
The system implements feedback mechanisms where the synchronization server monitors the status of supplementary service settings across UDM, HSS, and HLR nodes. When discrepancies or synchronization failures are detected, the system automatically triggers corrective actions to restore data consistency, ensuring information integrity across all nodes
3Reliability
If manual synchronization of supplementary service settings is performed, then network node coordination is achieved, but time consumption and operational errors increase
Solution Approach 1:
The synchronization server enables continuous automated synchronization of supplementary service settings between network nodes. Instead of periodic manual updates, the system maintains continuous data consistency through automated processes, eliminating synchronization delays and reducing the time required for node coordination while improving reliability through consistent data propagation

AI summary
Described herein are techniques, devices, and systems for synchronizing nodes that are utilized to provide services in a telecommunication network that includes a fifth generation (5G) network, and other types of networks. The nodes can be utilized to store supplementary service settings. A node of the 5G network that stores the supplementary service settings can be a unified data management (UDM). The UDM can be synchronized with a node (e.g., a home subscriber server (HSS)) that stores supplementary service settings in a long-term evolution (LTE) network, and/or a node (e.g., a home location register (HLR)) that stores supplementary service settings in a second generation (2G)/third generation (3G) network.
