Management Node Network Slicing Reallocation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless communication systems, particularly in 5G and beyond, network slicing management is complex due to the need for efficient allocation and reallocation of slicing entities to meet varying service requirements, especially in dynamic environments where reallocation events occur, requiring adaptive management to maintain service quality and stability.
Innovation Solution
A management node with a transceiver and processors allocates and reallocates slicing entities in response to allocation requests and reallocation events, using techniques like break before make, pre-allocation, and late deprovisioning to ensure that specified requirements are met, allowing for autonomous reallocation without requiring additional support from higher-level management nodes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If network slicing entities are dynamically reallocated to meet varying service requirements, then service adaptability and quality are improved, but management complexity increases
Solution Approach 1:
The patent segments the management function into hierarchical levels: a higher-level management node handles strategic slicing entity allocation, while lower-level management nodes handle operational reallocation decisions. This segmentation distributes management complexity across multiple levels, allowing dynamic service adaptation without overwhelming any single management entity.
Solution Approach 2:
The patent implements pre-allocation of slicing entities where the higher-level management node预先 allocates slicing entities to lower-level nodes based on predicted service requirements. This preliminary action prepares the system for dynamic reallocation needs, reducing the complexity of on-demand decision-making while maintaining high service adaptability.
2Reliability
If reallocation events are handled autonomously by management nodes, then service stability is improved through self-healing, but the risk of allocation errors increases
Solution Approach 1:
The patent implements a feedback mechanism where lower-level management nodes report reallocation status and service quality metrics back to the higher-level management node. This feedback loop enables continuous monitoring and correction of allocation decisions, maintaining service stability through self-healing while minimizing allocation errors through iterative optimization.
Solution Approach 2:
The patent enables lower-level management nodes to autonomously handle reallocation events using pre-configured policies and algorithms. This self-service capability allows rapid response to service disruptions, improving service stability through immediate self-healing actions while maintaining allocation accuracy through predefined decision frameworks.
3Adaptability or versatility
If slicing entities are reallocated frequently to meet changing requirements, then service quality is improved, but network disruption increases
Solution Approach 1:
The patent implements dynamic reallocation policies that adapt the frequency and timing of slicing entity reallocation based on service requirements and network conditions. This dynamic approach allows the system to optimize between service quality improvement and network stability by adjusting reallocation aggressiveness according to current operational context.
Solution Approach 2:
The patent employs periodic evaluation cycles for reallocation decisions, where the management node assesses whether reallocation is necessary at defined intervals rather than continuously. This periodic action reduces unnecessary reallocation operations that would disrupt the network, while still maintaining the ability to improve service quality when conditions warrant changes.

AI summary
A management node in a wireless communication system with a network slicing environment and an operating method thereof are provided. The method may include, in response to an allocation request from a higher-level management node, allocating a lower-level management node a first slicing entity that meets specified requirements for a network slice, obtaining the occurrence of a reallocation event, and in response to the occurrence of the reallocation event, reallocating the lower-level management node a second slicing entity that meets the specified requirements among slicing entities managed by the management node.
