Subscriber Information Synchronization Across Distributed Core Networks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In cellular networks with multiple core networks distributed and arranged, synchronizing subscriber information across HSSs is difficult due to the complexity of contracts and security concerns with conventional roaming methods, especially when a large number of operators are involved.
Innovation Solution
A management apparatus that includes a communication unit, storage unit, and control unit to manage and synchronize subscriber information across multiple core networks by designating copy destinations and controlling the transfer of subscriber information, reducing network congestion and security risks through intelligent selection of nearest core networks for data transfer.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional roaming methods are used to synchronize subscriber information across multiple core networks, then subscriber information can be accessed across networks, but network congestion increases and security risks arise due to complex contracts and data transfer protocols
Solution Approach 1:
The system segments subscriber information management by creating separate HSS instances for each core network. Each HSS stores local subscriber information independently, eliminating the need for cross-network data transfer and complex roaming contracts. This segmentation allows each core network to autonomously manage its subscribers without congestion or security risks from external access.
Solution Approach 2:
The patent implements local quality by enabling each core network to store and manage subscriber information locally in its own HSS. This local storage eliminates the need for remote data access and complex inter-network contracts, reducing network congestion and security risks while maintaining full functionality for subscriber management within each network.
2Stability of the object's composition
If subscriber information is stored in a single centralized HSS, then data consistency is maintained, but access efficiency decreases when multiple core networks are distributed across different locations
Solution Approach 1:
The system divides the centralized HSS into multiple distributed HSS instances, each serving a specific core network. This segmentation maintains data consistency within each local HSS while enabling fast access speeds by eliminating cross-network data transfer delays. Each HSS operates independently with its own subscriber information.
Solution Approach 2:
The patent transitions from a single-dimension centralized storage model to a multi-dimensional distributed storage architecture. Each core network has its own HSS dimension, allowing simultaneous local access without compromising data integrity through the replication and synchronization mechanisms across multiple dimensions.
3Productivity
If multiple core networks are distributed and arranged, then network coverage and capacity are improved, but the complexity of managing subscriber information across these networks increases
Solution Approach 1:
The system segments subscriber information management into independent units at each core network with its own HSS. This eliminates the need for complex centralized management systems and inter-network contracts, as each network autonomously manages its subscribers. The segmentation simplifies operations while maintaining expanded network coverage and capacity.
Solution Approach 2:
Each core network with its local HSS operates autonomously to manage its own subscriber information without requiring external coordination or complex management systems. This self-service approach reduces operational complexity while enabling multiple distributed networks to work together seamlessly for expanded coverage.

AI summary
There is provided a management apparatus which includes a storage unit and a control unit where the storage unit stores, for each subscriber, storage destination information indicating a core network in which subscriber information of the subscriber is stored. The control unit designates a subscriber and a core network, and receives an instruction of a copy of the subscriber information. When receiving the instruction of the copy, the control unit specifies a core network in which the subscriber information of the designated subscriber is stored from the storage destination information. The control unit performs control to copy the subscriber information of the designated subscriber from an HSS of the specified core network to an HSS of the designated core network.
