Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If network slicing technology is implemented to provide multiple networks with different SLAs on a common physical infrastructure, then service versatility and adaptability are improved, but device complexity and difficulty of managing network slices increase
Solution Approach 1:
The patent segments network slicing management into two distinct functional components: a first node that manages overall network slices and a second node that manages individual network slice subnets. This segmentation allows the system to handle multiple diverse services (eMBB, mMTC, URLLC) with different SLA requirements while distributing management complexity across specialized nodes, thereby maintaining service versatility without concentrating all complexity in a single device.
Solution Approach 2:
The patent introduces SLA arrangement flavor mapping relationship information as an intermediary mechanism between network slice requirements and subnet configurations. This mapping acts as a mediator that translates high-level SLA requirements into specific subnet resource allocations, simplifying the management process by providing a structured intermediate layer that bridges the gap between service requirements and infrastructure configuration.
2Speed
If network slice resource allocation is performed without SLA arrangement flavor mapping relationship information, then resource allocation speed is improved, but measurement precision and manufacturing precision of resource requirements deteriorate
Solution Approach 1:
The patent implements preliminary action by pre-establishing SLA arrangement flavor mapping relationship information that defines the correspondence between SLA parameters and required network resources. This pre-configured mapping information is stored and readily available, allowing the system to perform rapid resource allocation by simply querying the pre-defined relationships rather than calculating resource requirements in real-time, thus achieving both speed and precision.
3Measurement precision
If detailed SLA arrangement flavor mapping relationship information is collected and processed, then measurement precision of resource requirements is improved, but loss of time and difficulty of detecting and measuring increase
Solution Approach 1:
The patent uses copying by creating and storing SLA arrangement flavor mapping relationship information as a reusable reference data structure. Instead of performing complex calculations each time a network slice is allocated, the system copies and applies the pre-defined mapping relationships to specific allocation scenarios. This approach maintains high measurement precision for resource requirements while significantly reducing processing time by reusing established mapping patterns.
4Ease of operation
If network slice management is centralized in a single node, then ease of operation is improved, but device complexity and reliability decrease
Solution Approach 1:
The patent segments network slice management functions between two specialized nodes: the first node handles overall network slice management including coordination and high-level decision-making, while the second node handles specific network slice subnet management including resource allocation and configuration. This segmentation maintains operational ease by providing clear functional boundaries and specialized expertise at each level, while improving reliability through distributed architecture that eliminates single points of failure.

AI summary
The disclosure provides a method and a device for efficiently operating network slicing. According to the disclosure, a method of operating a first node configured to manage a network slice of a communication system includes: transmitting a service level agreement (SLA) range for each network slice subnet and a message requesting a resource according to the SLA range to a second node configured to manage the network slice subnet, receiving SLA arrangement flavor mapping relationship information in the network slice subnet unit from the second node, and identifying the SLA arrangement flavor mapping relationship in a network slice unit based on the received SLA arrangement flavor mapping relationship information in a network slice subnet unit.
