METHOD AND APPARATUS FOR MANAGING REGISTRATION OF NETWORK SLICE IN WIRELESS COMMUNICATION SYSTEM - A simplified explanation of the abstract

This abstract first appeared for US patent application 18045132 titled 'METHOD AND APPARATUS FOR MANAGING REGISTRATION OF NETWORK SLICE IN WIRELESS COMMUNICATION SYSTEM

Simplified Explanation

The abstract describes a method performed by an access and mobility management function (AMF) in a wireless communication system. The method involves transmitting a request message to a network slice admission control function (NSACF) for a slice availability check based on the access type of a user equipment (UE). The AMF then receives a response message from the NSACF regarding the result of the slice availability check and transmits a registration response to the UE based on the response message.

• The method involves checking the availability of network slices for a user equipment (UE) in a wireless communication system.
• The access and mobility management function (AMF) sends a request message to the network slice admission control function (NSACF) for the availability check.
• The request message includes information about the access type of the UE.
• The NSACF performs the slice availability check based on the access type of the UE.
• The AMF receives a response message from the NSACF containing information about the result of the slice availability check.
• Based on the response message, the AMF sends a registration response to the UE for the available network slices.

Potential Applications

• This method can be applied in wireless communication systems to efficiently manage network slices for user equipment (UE).
• It can be used to ensure that the appropriate network slices are available and accessible to the UE based on its access type.
• The method can be implemented in various wireless communication technologies such as 5G networks to enhance network slice management and allocation.

Problems Solved

• The method solves the problem of efficiently managing network slices for user equipment (UE) in a wireless communication system.
• It addresses the challenge of ensuring that the appropriate network slices are available and accessible to the UE based on its access type.
• The method provides a systematic approach for checking the availability of network slices and registering the UE accordingly.

Benefits

• The method allows for efficient management and allocation of network slices, optimizing the utilization of resources.
• It ensures that the UE has access to the appropriate network slices based on its access type, improving the overall user experience.
• The method provides a standardized and automated process for checking slice availability and registering the UE, reducing manual intervention and potential errors.

Original Abstract Submitted

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.
