Network Slice Instance Management via Function Update
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current network management solutions do not effectively support the management and updating of network slice instances, particularly in next-generation mobile networks, which require flexible and dynamic communication services to meet diverse communication requirements.
Innovation Solution
A method and apparatus for managing network slice instances, where a first network device receives an update request, configures and updates network functions, and communicates with other devices to ensure seamless transitions and resource allocation, including determining dependencies and sharing of network functions, to enhance user experience and network efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a conventional cellular network architecture is used, then network service uniformity is maintained, but the ability to meet differentiated communication requirements is insufficient
Solution Approach 1:
The patent segments the network into multiple network slice instances, each tailored to specific service requirements. The network is divided into independent slices that can be managed separately, allowing differentiated communication requirements to be met without affecting the entire network structure.
Solution Approach 2:
The patent creates a universal network slice management capability that can handle multiple types of services (eMBB, mMTC, uMTC) through a common management framework. The network slice instance can serve multiple functions and be configured for different service types using the same underlying infrastructure.
2Adaptability or versatility
If network slice instances are created to meet diverse service requirements, then service differentiation is achieved, but management capability becomes insufficient
Solution Approach 1:
The patent introduces a network slice manager as an intermediary between the network slice instances and the management system. This manager handles the complexity of slice instance management, including updates and configurations, providing an easier interface for operation while maintaining service differentiation.
Solution Approach 2:
The network slice instance is designed with self-service capabilities, allowing it to autonomously handle certain management tasks such as updates. The instance can receive update requests and perform self-upgradation without requiring complex manual intervention, simplifying the management process.
3Productivity
If network slice instance updates are performed, then network function upgrading is achieved, but management support becomes insufficient
Solution Approach 1:
The patent implements preliminary action by having the network slice manager prepare and validate update requests before execution. The manager can pre-process update information, check compatibility, and plan the update sequence, enabling efficient network function upgrading while maintaining proper management control.
Solution Approach 2:
The patent incorporates feedback mechanisms where the network slice instance reports its status and update progress to the network slice manager. The manager uses this feedback to coordinate updates across multiple instances, ensuring efficient upgrading while maintaining management oversight and handling dependencies between slices.

AI summary
Embodiments of this application provide a method and an apparatus for managing a network slice instance. The method includes: receiving, by a first network device, an update request message sent by a transmit end, where the update request message is used to request to update a first network function of the first network slice to a second network function; sending, by the first network device, a first configuration request message to a second network device based on the update request message; receiving, by the first network device, a configuration response message sent by the second network device based on the first configuration request message; and sending, by the first network device, an update response message to the transmit end based on the configuration response message. According to the method and the apparatus for managing a network slice provided in the embodiments of this application, a network function for providing a service for a network slice instance can be modified and upgraded, thereby updating the network slice instance, and improving user experience.
