Solution Overview
Problem
Existing wireless communication systems face challenges in managing network slice registration efficiently, particularly in 6G communication systems, where the exponential growth of connected devices and services requires advanced technologies to secure coverage, spectral efficiency, and network optimization, including network slicing for diverse access types.
Innovation Solution
Implementing a method and apparatus for managing network slice registration through the interaction between the Access and Mobility Management Function (AMF) and Network Slice Admission Control Function (NSACF) to perform slice availability checks based on user equipment access types, ensuring efficient allocation and registration of network slices.

Engineering Contradiction Analysis
1Ease of manufacture
If network slice registration is managed without access type differentiation, then the registration process is simpler, but resource allocation efficiency deteriorates for diverse access types
Solution Approach 1:
The patent segments the network slice registration process by access type, creating separate registration procedures for 3GPP access and non-3GPP access. This segmentation allows the system to optimize resource allocation for each access type independently while maintaining manageable complexity through standardized handling within each segment.
Solution Approach 2:
The patent implements dynamic registration management where the AMF and NSACF adapt the registration process based on the UE's access type. The system dynamically selects appropriate registration procedures and resource allocation strategies according to whether the access is 3GPP or non-3GPP, enabling efficient resource utilization across diverse access scenarios.
2Productivity
If slice availability check is performed for all access types, then network resource allocation is optimized, but the complexity of the registration process increases
Solution Approach 1:
The patent applies local quality by performing slice availability checks selectively based on access type. The NSACF performs detailed slice availability verification for access types that require it (such as non-3GPP access), while simplifying or skipping checks for access types where they are less critical (such as 3GPP access), thereby optimizing resource allocation without uniformly increasing complexity across all scenarios.
Solution Approach 2:
The patent implements preliminary slice availability checks by the NSACF before finalizing network slice registration. This preliminary action ensures that slice resources are properly allocated and available before committing the registration, preventing resource conflicts and ensuring optimal network resource utilization from the outset.
3Measurement precision
If access type information is included in slice availability check, then resource allocation accuracy is improved, but the information processing overhead increases
Solution Approach 1:
The patent creates a universal message structure that carries access type information applicable to all network slice registration scenarios. This multi-functional message format enables the system to handle different access types (3GPP and non-3GPP) with a single standardized approach, improving resource allocation accuracy across all access types while avoiding the need for multiple specialized processing paths that would increase overhead.
Data Source
AI summary
A method performed by an access and mobility management function (AMF) in a wireless communication system may include: transmitting, to a network slice admission control function (NSACF), a request message for a slice availability check including information regarding an access type of a user equipment (UE), based on a registration request of the UE for one or more single network slice selection assistance information (S-NSSAI); in case that the slice availability check is performed for the one or more S-NSSAIs at the NSACF, based on the access type of the UE, receiving a response message including information regarding a result of the slice availability check, from the NSACF; and transmitting a registration response for the one or more S-NSSAIs to the UE, based on the response message.
