Storage Resource Controller for 5G UDSF Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The 5G network system faces challenges in managing unstructured data storage across multiple network functions, particularly in ensuring independent management of services, data replication, and synchronization across different data centers, with existing mechanisms lacking for these purposes.
Innovation Solution
A method and apparatus for managing storage resources in a network system, where a storage resource controller registers with a network repository function, receives operation requests from consumer services, selects appropriate resource management instances, and forwards these requests to corresponding Unstructured Data Storage Function (UDSF) instances, enabling efficient data management and replication across data centers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If a single UDSF instance is shared across multiple NF instances, then storage resource utilization is improved, but service independence and data consistency across different data centers deteriorate
Solution Approach 1:
The patent segments the storage system into multiple independent UDSF instances distributed across different data centers, with each instance serving specific NF instances. This segmentation allows storage resources to be independently managed while maintaining service independence and data consistency through selective assignment of UDSF instances to specific NF instances or service instance sets.
2Reliability
If multiple UDSF instances are deployed for different NF instances, then service independence and data consistency are improved, but system complexity and management overhead increase
Solution Approach 1:
The patent introduces the NRF (Network Repository Function) as an intermediary that manages the mapping between NF instances and UDSF instances. The NRF stores and provides information about available UDSF instances, enabling NF instances to discover and connect to appropriate storage resources without complex direct management relationships, thus reducing system complexity while maintaining service independence.
3Adaptability or versatility
If UDSF instances are distributed across multiple data centers, then data replication and synchronization capabilities are improved, but network latency and coordination overhead worsen
Solution Approach 1:
The patent applies local quality by allowing different UDSF instances in different data centers to serve different NF instances or service instance sets locally. This reduces network latency by minimizing cross-data-center communication for routine operations, while still enabling data replication and synchronization capabilities through the distributed architecture when needed.

AI summary
A method for managing storage resources in a network system is described. The method includes registering, by a storage resource controller, with a network repository function; receiving, by the storage resource controller, an operation request from a consumer service; selecting, by the storage resource controller, a resource management instance from a plurality of resource management instances managed by the storage resource controller for assignment to the consumer service; forwarding, by the storage resource controller, the operation request to the selected resource management instance; receiving, by the storage resource controller, an operation response from the selected resource management instance; and forwarding, by the storage resource controller, the operation response to the consumer service.
