Network Slice Capability Exposure With Permission-Based Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The efficiency of utilizing network slice management capabilities and resources in mobile communication networks is low due to insufficient exposure and management of network slice services, leading to suboptimal utilization of network resources.
Innovation Solution
A network management system is introduced to expose and manage network slice management capabilities, allowing third-party application servers to request and interact with network slice management services, including template and capability services, with permission access policies to ensure efficient and secure utilization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If network slice management capabilities are exposed to third-party servers, then service diversity and resource utilization improve, but system security and access control complexity increase
Solution Approach 1:
The network management system is segmented into multiple functional modules including exposure functions, policy management functions, and authorization functions. This segmentation allows different components to handle specific tasks independently, reducing overall system complexity while maintaining service diversity. The exposure function specifically separates capability exposure from core management operations.
Solution Approach 2:
An intermediary exposure function is introduced between third-party servers and core network management capabilities. This intermediary layer provides standardized interfaces for capability exposure while maintaining security and access control policies, thus enabling service diversity without directly increasing core system complexity.
2Productivity
If network slice management capabilities are exposed to third-party servers, then resource utilization efficiency improves, but system security risks increase
Solution Approach 1:
Access control policies and authorization mechanisms are established and configured in advance before third-party servers access network slice management capabilities. The exposure function pre-defines which capabilities can be accessed and under what conditions, ensuring security is built-in from the start rather than added later, thus maintaining both high resource utilization and system security.
3Productivity
If more network capabilities are exposed for third-party access, then service provision efficiency improves, but management complexity increases
Solution Approach 1:
The exposure function is designed as a universal multi-functional component that can expose multiple different network capabilities through a standardized interface mechanism. This allows various network slice management capabilities to be exposed without proportionally increasing management complexity, as the same exposure framework handles different capabilities uniformly.

AI summary
Embodiments of the present disclosure provide a service provision method, a device, and a storage medium. In the embodiments of the present disclosure, a network management service user (such as a third-party server) can easily and quickly acquire a service related to a network management capability by performing capability exposure on a network management system in an operator network; further, in the process of exposing the network management capability, a permission access policy is added, so that the network management service user can only use a network management capability service with an access permission, which is favorable for reasonably exposing the network management service capability, so as to safely and efficiently provide the network management capability service, and improve the utilization efficiency of the network management capability in the operator network.
