Network Slice Selection for Third-Party Service Platforms
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In the 5G network system, third-party service platforms lack the ability to directly control which network slices User Equipment (UE) accesses, limiting their flexibility in providing different Quality of Service (QoS) levels based on user configuration information.
Innovation Solution
A method and apparatus that allow a third-party service platform to interact with the 5G Core network to select a suitable network slice for a user based on updated configuration information, enabling active control over the network slice accessed by the UE, thereby simplifying interactions with mobile network operators and enhancing QoS flexibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If third-party service platforms use traditional network slice access methods, then network slice selection is determined by subscription information, but third-party platforms cannot directly control which network slices UE accesses
Solution Approach 1:
The patent introduces a network slice selection function (NSSF) as an intermediary entity that mediates between third-party service platforms and the core network. The NSSF receives configuration information from third-party platforms, processes it according to network policies, and selects appropriate network slices, thereby enabling third-party control while simplifying the overall system architecture
Solution Approach 2:
The patent segments the network slice selection process into independent functional components: third-party service platforms provide configuration information, the NSSF processes and selects network slices, and the core network executes the selection. This segmentation allows each component to operate independently, improving controllability while reducing interaction complexity
2Adaptability or versatility
If third-party service platforms want to provide different QoS levels for users, then they need to control network slice selection, but the current subscription information-based approach does not allow this flexibility
Solution Approach 1:
The patent enables dynamic network slice selection based on real-time configuration information from third-party platforms. Instead of static subscription-based selection, the system can dynamically adjust network slice assignments according to user requirements, service types, and network conditions, providing flexible QoS control
Solution Approach 2:
The patent changes the selection parameters from fixed subscription information to dynamic configuration information that includes service type, user identity, and network conditions. This parameter change enables the system to adapt network slice selection to different QoS requirements while maintaining ease of operation for third-party platforms

AI summary
A network slice selection method includes, in response to an update in configuration information of a user of a media service, determining first information indicating updated configuration information of the user of the media service. The first information indicates an updated selection of a first network slice from at least two network slices. The method further includes transmitting, by the media service, the first information to an entity of a 5G Core network.
