Engineering Contradiction Analysis
1Adaptability or versatility
If current pairing mechanisms are used, then network operations can be maintained, but dynamic pairing of RAN and CN slices based on location and resource availability cannot be achieved
Solution Approach 1:
A pairing service is introduced as an intermediary component that manages the pairing between RAN slices and CN slices. This service receives pairing capabilities from both RAN and CN sides, determines appropriate pairings based on location and resource availability, and provides pairing information to network elements. This mediator approach enables dynamic pairing functionality without requiring complex direct interactions between RAN and CN elements.
Solution Approach 2:
The pairing service implements feedback mechanisms by receiving pairing capability information from both RAN and CN sides, processing this information to determine optimal pairings, and providing pairing information back to network elements. This feedback loop enables adaptive pairing decisions based on current network conditions, resource availability, and location information.
2Productivity
If static pairing approaches are used, then implementation is simpler, but scalability and flexibility for diverse use cases are limited
Solution Approach 1:
The pairing service enables dynamic pairing of RAN and CN slices based on current network conditions, location information, and resource availability. Pairing decisions are not fixed but can change in response to varying network conditions, supporting different use cases and services. This dynamic approach enhances network scalability and flexibility while maintaining manageable complexity through the centralized pairing service.

AI summary
A method, a device, and a non-transitory storage medium are described in which a radio access network slice and core network slice service is provided based on RAN-CN network slice pairing information. A radio access network slice and/or a core network slice uses the RAN-CN network slice pairing information to select network resources to support sessions of end devices. The RAN-CN network slice pairing information may include location information, radio access network slice information, core network slice information correlated to different types or applications or services available to end devices. The RAN-CN network slice pairing information may include information indicating current and available radio access network resources pertaining to the radio access network slices and threshold resources that may be used to support the different types of applications or services.
