Network Slice Management via Priority List for Connection Reliability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In a network system, terminals are unable to connect to a suitable slice for service provision when the specified slice is not available, leading to service rejection, even if alternative slices can meet the service requirements.
Innovation Solution
A slice management system that prioritizes connection destination candidates based on a memory-stored priority list, allowing terminals to connect to the most appropriate slice associated with the user or service request, and dynamically updates the priority list based on operation statuses, service conditions, and contract information.

Engineering Contradiction Analysis
1Ease of operation
If a terminal requests connection to a uniquely specified slice based on service type, then the connection process is simple and straightforward, but the terminal cannot connect to any slice when the specified slice is unavailable, leading to service rejection
Solution Approach 1:
The system pre-establishes a priority list containing multiple slice identifiers before the terminal makes a connection request. When the terminal requests connection, the system already has the ordered list of candidate slices ready, eliminating the need for real-time search and evaluation processes.
Solution Approach 2:
The system dynamically selects a slice from the priority list based on availability status. When the specified slice is unavailable, the system automatically falls back to the next slice in the priority list, making the connection process adaptive and resilient to slice unavailability.
2Device complexity
If the system provides only a single specified slice for each service type, then the network configuration is simple, but the system lacks flexibility to handle slice unavailability or optimize connection based on real-time conditions
Solution Approach 1:
Instead of providing a single slice identifier, the system segments the connection options into a prioritized list of multiple slice identifiers. This segmentation allows the system to offer multiple connection paths while maintaining a structured and manageable configuration approach.
Solution Approach 2:
The system changes the parameter from a single slice identifier to a prioritized list of slice identifiers. This parameter transformation enables the system to express multiple connection options with different priority levels, significantly enhancing adaptability without requiring complex configuration mechanisms.

AI summary
A slice management system (1) is a slice management system managing slices that are virtual networks generated on a network infrastructure, comprises a memory storing a priority list in which slices of connection destination candidates of a UE (2) are aligned in order of priority levels and, in a case in which a connection request for a slice from the UE (2) is acquired, determines a slice to which UE (2) is to be connected on the basis of the priority list stored in the memory.
