Solution Overview

Problem

There is no obvious implementation method for satisfying the demands of Enhanced Network Slicing (eNS) and Enhanced Non-Public Network (eNPN) in the 5G System (5GS).

Innovation Solution

A core network apparatus that includes a controller and a transmission and/or reception unit, which performs a registration procedure for an onboarding service on a Stand-alone Non-Public Network (SNPN) without conducting network slice admission control, and transmits either a registration accept message or a registration reject message.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If network slice admission control is performed during registration procedure for onboarding service on SNPN, then network resource management is improved, but registration process complexity increases

Engineering Contradiction:

Improvenetwork resource managementVSAvoidregistration process complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent extracts network slice admission control from the registration procedure for onboarding services on SNPN. The controller is configured to not perform network slice admission control specifically when the registration procedure is initiated for an onboarding service on an SNPN, while maintaining other registration control functions. This separation resolves the contradiction by removing the problematic control element from the specific context where it causes complexity.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

Instead of applying network slice admission control universally during registration procedures, the patent inverts the approach by explicitly excluding this control mechanism for onboarding services on SNPN. The controller is configured to perform registration control for normal services but deliberately omits network slice admission control for onboarding scenarios, achieving simplicity where needed while maintaining control where necessary.

Inventive Principle:

Principle #13The other way round (Inversion)

2Reliability

If network slice admission control is implemented, then service quality is improved, but implementation complexity increases

Engineering Contradiction:

Improveservice qualityVSAvoidimplementation complexity

Core Design Contradiction:

ReliabilityVSEase of manufacture

Solution Approach 1:

The patent applies local quality by making network slice admission control selective rather than universal. The controller differentiates between regular services and onboarding services on SNPN, applying admission control only where service quality requires it while omitting it for onboarding scenarios. This localized application reduces overall implementation complexity while maintaining service quality where necessary.

Inventive Principle:

Principle #3Local quality

AI summary

A communication element for realizing a function related to management of information about network slices or a non-public network function is provided in 5GS. In the 5GS, a method and a communication element for procedures of initial registration of a UE (A10) and a periodic or movement-based registration for realizing management of information about network slices or the non-public network function are provided. Furthermore, a method and a communication element for a network slice-specific authentication and authorization procedure after completion of a registration procedure, a UE configuration update procedure and a deregistration procedure are provided.
