Network Slice Management Isolating Shared Resources
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Managing network slices in 5G systems is challenging due to the difficulty in extending conventional cellular network architectures to meet diverse and changing user needs, requiring flexible resource allocation and isolation to ensure service level agreements (SLAs) are met.
Innovation Solution
A network slice management method involving a first management unit that obtains isolation-sharing requirement information and sends a network slice management request message to a second management unit to select, create, or configure network slices based on isolation-sharing requirements, allowing for shared or exclusive network slices to be provided.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional cellular network architecture with dedicated support system is used, then the network can be used to predict traffic and traffic growth, but the operator has difficulty in extending the telecommunication network and performing adjustment based on continuously changing user needs
Solution Approach 1:
The patent segments the network architecture into multiple network slices, each independently managed according to specific service requirements. This allows the network to maintain stable core functions while enabling flexible creation of specialized slices for different use cases, resolving the contradiction between reliability and adaptability.
Solution Approach 2:
The patent introduces dynamic network slice management capabilities that allow the network to be reconfigured and adjusted based on changing user needs. Network slices can be created, modified, or terminated dynamically without affecting the overall network stability, enabling continuous adaptation to new requirements.
2Adaptability or versatility
If network slices are created to meet diverse service requirements, then flexible resource allocation can be achieved, but the complexity of managing multiple network slices increases
Solution Approach 1:
The patent introduces a network slice management system that acts as an intermediary between service requirements and network resources. This management system abstracts the complexity of managing multiple network slices by providing standardized interfaces and automated management functions, reducing the operational burden while maintaining resource allocation flexibility.
3Productivity
If network sharing is implemented to optimize shared network resources, then better quality of service can be provided, but isolation between different network slices becomes more challenging
Solution Approach 1:
The patent applies different isolation levels to different network slices based on their specific requirements. Some slices may share resources extensively while maintaining logical isolation, while others require stricter physical isolation. This localized approach to quality control allows optimal resource sharing while meeting diverse isolation requirements of different services.

AI summary
Embodiments of the present invention relate to a network slice management method and a management network element. The method includes: obtaining, by a first management unit, isolation-sharing requirement information of a network slice or first indication information, where the first indication information is used to obtain the isolation-sharing requirement information of the network slice; and sending, by the first management unit, a network slice management request message to a second management unit, where the network slice management request message carries the isolation-sharing requirement information of the network slice or the first indication information, and the network slice management request message is used to instruct the second management unit to select, create, configure, or request to configure the network slice. It can be learned from the foregoing descriptions that a specific solution of choosing to provide a shared network slice or an exclusive network slice for a tenant is provided in the embodiments of the present invention.
