Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If network slicing is implemented to provide customized network services, then network function customization and performance optimization are improved, but network slice management and control capabilities are insufficient
Solution Approach 1:
The patent segments network slices into different types (exclusive slices and shared slices) and manages them through separate control mechanisms. The slice controller independently manages each network slice's resources, allowing customized network functions while simplifying management through structured segmentation.
Solution Approach 2:
The patent introduces a slice controller as an intermediary component between the network slice selection function and the network resources. This mediator automatically manages network slice allocation, resource allocation, and switching based on user priorities, reducing management complexity while enabling customized services.
2Reliability
If dynamic network slice switching is implemented to meet user priorities, then network performance is improved, but network slice selection and control complexity increases
Solution Approach 1:
The patent implements dynamic network slice switching where the slice controller can dynamically allocate users to different network slices (exclusive or shared) based on real-time priority requirements. This dynamic adjustment improves network performance while the automated control mechanism prevents complexity from becoming unmanageable.
Solution Approach 2:
The patent incorporates feedback mechanisms where the slice controller monitors user priorities and network conditions, then adjusts network slice allocation accordingly. This feedback loop ensures optimal performance while the systematic approach to feedback processing prevents control complexity from escalating.
3Reliability
If exclusive network slices are allocated to high-priority users, then network quality for critical services is improved, but network resource utilization efficiency decreases
Solution Approach 1:
The patent applies local quality by providing exclusive network slices with enhanced resources to high-priority users who require guaranteed network quality, while allowing standard-quality shared slices for other users. This differentiated service approach ensures critical services receive optimal quality while maintaining overall resource utilization efficiency through selective exclusivity.
Solution Approach 2:
The patent implements partial exclusivity where only necessary network resources are allocated exclusively to high-priority users rather than providing complete isolation. This partial action approach ensures adequate network quality for critical services while avoiding excessive resource reservation that would reduce overall system efficiency.
4Adaptability or versatility
If network slice switching is implemented to respond to business requests, then user requirements are met, but network control and management difficulty increases
Solution Approach 1:
The patent implements self-service through the slice controller, which automatically processes business requests, selects appropriate network slices, allocates resources, and executes switching without manual intervention. This automation fulfills diverse user requirements while significantly reducing the operational complexity and management burden on network administrators.
Solution Approach 2:
The slice controller serves multiple functions including business request processing, network slice selection, resource allocation, and slice switching within a single integrated component. This multi-functionality enables comprehensive user requirement fulfillment while consolidating control logic to reduce overall network management complexity.

AI summary
A request processing method includes: determining, based on a request of a terminal, first network slice information of a current network slice accessed by the terminal, and acquiring second network slice information respectively corresponding to at least one subscribed network slice, the subscribed network slice being a network slice allowing access of the terminal; and determining whether there is a detection result of target second network slice information satisfying an access condition in the respective second network slice information, and controlling the current network slice based on the detection result.
