Dynamic Network Slice Switching for Consistent User Service Quality
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional network slice switching methods based on user terminal service context fail to provide uniform service quality due to resource constraints and varying user needs, leading to inconsistent service levels.
Innovation Solution
A network-slice control server and service server system that allows a service provider to issue instructions for switching network slices based on resource usage and user-specific service quality requirements, utilizing an exposure server to monitor and manage network resources and update subscriber information for seamless connectivity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If network slice is switched based on user terminal service context with core network determination, then service flexibility is improved, but service quality uniformity deteriorates due to resource constraints and varying user needs
Solution Approach 1:
The patent introduces a service server as an intermediary between the core network and user terminals. This service server receives service context information from the core network, determines appropriate network slice selections, and provides instructions to user terminals. This intermediary role enables centralized control of network slice selection, ensuring uniform service quality across all users while maintaining service flexibility through the service server's decision-making capability.
2Productivity
If service provider allocates resources according to service demand estimation, then resource allocation efficiency is improved, but service quality consistency deteriorates due to physical resource and cost constraints
Solution Approach 1:
The patent implements dynamic network slice selection where the service server continuously monitors service context information and adjusts network slice assignments in real-time. This dynamic approach allows the system to adapt to changing service demands and resource availability, optimizing resource allocation efficiency while maintaining service quality consistency through centralized control and coordinated resource management across the network.

AI summary
A service server of a service provider issues an instruction for switching regarding a network slice to be applied to a user terminal. The network-slice control server receives, from the service server of the service provider, the instruction for switching to the network slice to be applied to the user terminal. The network-slice control server transmits, to a subscriber management server, an instruction for changing subscriber information regarding the user terminal, on the basis of the instruction for switching to the network slice received from the service server. Thus, the subscriber information regarding the user terminal is changed in the subscriber management server.
