Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If network slicing is implemented to support multiple services, then service diversity and adaptability are improved, but network complexity and difficulty of management increase
Solution Approach 1:
The network is divided into multiple independent network slices, each configured with specific NFs and parameters to support different services. This segmentation allows diverse services to run in isolated virtual environments while maintaining manageable complexity through modular configuration.
Solution Approach 2:
The network slice configuration mechanism provides universal management capabilities across different service types. A single configuration framework handles multiple services by parameterizing slice-specific requirements, enabling the system to manage diverse services through a unified interface rather than requiring separate management systems for each service type.
2Productivity
If strict quota control is implemented for network slices, then network resource utilization is optimized, but service availability and user flexibility are reduced
Solution Approach 1:
The quota control mechanism dynamically adjusts resource allocation based on slice status information and operational parameters. Rather than enforcing static quotas, the system monitors resource consumption patterns and service requirements, allowing flexible adjustment of quota limits to maintain both efficient resource utilization and service availability under varying conditions.
Solution Approach 2:
The system implements feedback loops where network function devices report status information about slice resource usage, and this information is used to adjust quota parameters. The feedback mechanism enables the system to respond to actual resource consumption patterns, ensuring quotas are set appropriately to optimize utilization while preventing service degradation.
3Measurement precision
If detailed status information is collected and reported for each network slice, then access control precision is improved, but information processing overhead and system complexity increase
Solution Approach 1:
The system extracts only the essential status information parameters needed for access control decisions from the complete set of possible network slice data. By identifying and reporting only the critical parameters (such as resource usage thresholds, service quality metrics, and capacity indicators), the system achieves precise access control without the overhead of processing and transmitting unnecessary information.

AI summary
Provided in the present disclosure are a method and a device for providing a service to a user device by using a network slice in a communication system. A method according to one embodiment of the present disclosure can comprise the steps of: receiving, from a second network function device, management function configuration information about a first core network slice, including the quota of a first core network slice; reporting status information about the first core network slice to a third network function device on the basis of the management function configuration information; receiving, from the third network function device, parameters for controlling the status of the first core network slice; and controlling access of a terminal that is to use the first core network slice, on the basis of the status information about the first core network slice and the parameters for control.
