Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If QoS mechanism is applied at UE level or data flow level, then service quality can be guaranteed for individual users, but it is difficult to meet industry client requirements for slice-level service functions
Solution Approach 1:
The patent segments the network into multiple isolated logical subnetworks (slices) at the network level, each capable of providing dedicated service functions. This is achieved by virtualizing network resources and creating separate logical networks that can be independently managed and configured for different industry clients, thereby enabling slice-level service functions while maintaining service quality guarantees.
2Productivity
If network resources are shared among multiple slices, then resource utilization efficiency improves, but it becomes difficult to ensure quality of service at the appropriate level for each slice
Solution Approach 1:
The patent implements local quality by allowing each network slice to have customized Quality of Service (QoS) parameters and resource allocations tailored to specific industry client requirements. Each slice can be configured with dedicated bandwidth, latency constraints, and other QoS metrics, ensuring that service quality is guaranteed at the slice level while resources remain shared across multiple slices through virtualization.
3Adaptability or versatility
If network slicing is implemented to provide isolated logical subnetworks, then slice-level resource control is enabled, but the complexity of generating and managing slice-level QoS parameters increases
Solution Approach 1:
The patent introduces a network management system as an intermediary that automatically generates, transmits, and manages slice-level QoS parameters. This intermediary system simplifies the complexity by providing automated tools and interfaces for configuring and controlling QoS parameters across multiple slices, reducing the manual burden and enabling efficient slice-level resource control.

AI summary
Embodiments of the present application disclose a network slice processing method, system and device and a storage medium. The method is applied to a network management system, and comprises: virtualizing a function of a mobile communication network so as to obtain multiple logical subnets isolated from each other, wherein each logical subnet serves as a network slice; generating a slice-level quality of service (QoS) parameter for each network slice, wherein the slice-level QoS parameter is used by the network management system to instruct a slice processing device to control a first resource corresponding to the network slice; and transmitting the slice-level QoS parameter to the slice processing device.
