## Abstract

A disclosure of the present specification (disclosure) provides a method for performing communication by an AMF. According to the method, an AMF may receive a registration message including requested NSSAI information. The AMF may transmit a response message to a UE in response to a registration request message.

## Claims

### Claim at position 1

1-15. (canceled)

### Claim 16

A method for performing a communication the method performed by an Access and Mobility Management Function (AMF) and comprising:
receiving, from a User Equipment (UE), a registration request message including requested network slice selection assistance information (NSSAI); and
transmitting a response message to the UE,
wherein the response message includes partially allowed NSSAI or Single-NSSAI (S-NSSAI) rejected partially in a registration area,
wherein the response message includes a list of tracking area (TA) where a S-NSSAI in the partially allowed NSSAI is supported, based on that the partially allowed NSSAI is included in the response message, and
wherein the response message includes a list of TA where a S-NSSAI in the S-NSSAI rejected partially in the registration area is not supported, based on that the S-NSSAI rejected partially is included in the response message.

### Claim 17 (depends on 16)

The method of claim 16,
wherein the TA list where the S-NSSAI in the partially allowed NSSAI is supported includes one or more TAs included in the registration area.

### Claim 18 (depends on 16)

The method of claim 16, further comprising:
receiving a registration request message including a requested NSSAI including the S-NSSAI rejected partially in the registration area from the UE, based on the UE being in a TA supporting the S-NSSAI rejected partially in the registration area.

### Claim 19 (depends on 16)

The method of claim 16,
wherein the response message includes a reject cause related to that rejected partially in the registration area.

### Claim 20 (depends on 16)

The method of claim 16, further comprising:
receiving capability information related to that the UE supports partial network slice support in the registration area, from the UE.

### Claim 21 (depends on 16)

The method of claim 16, further comprising:
transmitting information related to that the UE moved out of a network slice area of support to a Session Management Function (SMF).

### Claim 22

A method for performing a communication the method performed by a User Equipment (UE), and comprising:
transmitting a registration request message including requested network slice selection assistance information (NSSAI) to an Access and Mobility Management Function (AMF); and
receiving a response message from the UE,
wherein the response message includes partially allowed NSSAI or Single-NSSAI (S-NSSAI) rejected partially in a registration area,
wherein the response message includes a list of tracking area (TA) where a S-NSSAI in the partially allowed NSSAI is supported, based on that the partially allowed NSSAI is included in the response message, and
wherein the response message includes a list of TA where a S-NSSAI in the S-NSSAI rejected partially in the registration area is not supported, based on that the S-NSSAI rejected partially is included in the response message.

### Claim 23 (depends on 22)

The method of claim 22,
wherein the TA list where the S-NSSAI in the partially allowed NSSAI is supported includes one or more TAs included in the registration area.

### Claim 24 (depends on 22)

The method of claim 22, further comprising:
transmitting a registration request message including a requested NSSAI including the S-NSSAI rejected partially in the registration area to the AMF, based on the UE being in a TA supporting the S-NSSAI rejected partially in the registration area.

### Claim 25 (depends on 22)

The method of claim 22,
wherein the response message includes a reject cause related to that rejected partially in the registration area.

### Claim 26 (depends on 22)

The method of claim 22, further comprising:
transmitting capability information related to that the UE supports partial network slice support in the registration area, to the AMF.

### Claim 27

A User Equipment (UE) for performing a communication,
at least one processor; and
at least one memory that stores instructions and is operably electrically coupled to the at least one processor,
based on being executed by the at least one processor, perform operations comprising:
transmitting a registration request message including requested network slice selection assistance information (NSSAI) to an Access and Mobility Management Function (AMF); and
receiving a response message from the UE,
wherein the response message includes partially allowed NSSAI or Single-NSSAI (S-NSSAI) rejected partially in a registration area,
wherein the response message includes a list of tracking area (TA) where a S-NSSAI in the partially allowed NSSAI is supported, based on that the partially allowed NSSAI is included in the response message, and
wherein the response message includes a list of TA where a S-NSSAI in the S-NSSAI rejected partially in the registration area is not supported, based on that the S-NSSAI rejected partially is included in the response message.

### Claim 28 (depends on 27)

The UE of claim 27,
wherein the UE is an autonomous driving device in communication with at least one of a mobile terminal, a network, and an autonomous vehicle other than the UE.
