Network Entity for Managing Slice SLA Distribution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for improved network entities to efficiently manage the distribution of slice service level agreement (SLA) information of a network slice in a mobile communication network.
Innovation Solution
The implementation of network entities that obtain and provide slice SLA indications to control the distribution of slice SLA information, supporting parameters such as maximum UEs and PDU sessions per network slice, and ensuring efficient quota enforcement and policy management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If network entities manually manage slice SLA information distribution, then service level agreements can be enforced, but management efficiency and resource utilization are insufficient
Solution Approach 1:
The network entities automatically obtain slice SLA indications from network control entities and distribute slice SLA information to relevant network functions without manual intervention. The system self-manages the distribution process by receiving indications containing SLA parameters (such as maximum UEs per slice, maximum PDU sessions per slice, throughput guarantees) and automatically enforcing these policies across the network, thereby improving management efficiency while maintaining enforceability of service level agreements.
2Speed
If centralized control is used for slice SLA management, then policy consistency is maintained, but distribution efficiency and responsiveness are reduced
Solution Approach 1:
The system segments slice SLA management by allowing network entities to obtain slice SLA indications from network control entities and distribute slice SLA information locally to relevant network functions. This segmentation enables faster local distribution while maintaining policy consistency through the standardized indication format that includes SLA parameters (maximum UEs, maximum PDU sessions, throughput guarantees) defined by the network control entity.
Solution Approach 2:
The network control entity prepares slice SLA indications in advance containing all necessary SLA parameters (maximum UEs per slice, maximum PDU sessions per slice, throughput guarantees, etc.) before distribution. This preliminary preparation ensures that when slice SLA information is distributed to network functions, it is immediately ready for enforcement, achieving both fast distribution and policy consistency.
