## Abstract

The disclosure relates to a communication technique and system for converging a 5G communication system for supporting higher data rates beyond a 4G system with an IoT technology. The disclosure relates to a wireless communication system, and more particularly, to a method and an apparatus for providing a local area data network service based on a non-subscription model in a cellular wireless communication system (5G system).

## Claims

### Claim 1

A method by an access and mobility management function (AMF) entity in a wireless communication system, the method comprising:
receiving, from a terminal, a first message for requesting a protocol data unit (PDU) session establishment including a first local area data network (LADN) data network name (DNN);
determining whether the first LADN DNN is configured at the AMF entity as a LADN DNN;
determining whether the terminal is present in a LADN service area, in case that the first LADN DNN is configured at the AMF entity as the LADN DNN; and
transmitting, to a session management function (SMF) entity, a second message indicating whether the terminal is present in the LADN service area.

### Claim 2 (depends on 1)

The method of claim 1, wherein the second message indicates the terminal is IN or OUT of the LADN service area.

### Claim 3 (depends on 1)

The method of claim 1, further comprising:
receiving, from the SMF entity, information that the SMF entity subscribes to a terminal mobility event report service.

### Claim 4 (depends on 3)

The method of claim 3, wherein the information indicates that the SMF entity subscribes to the terminal mobility event report service in case that the second message indicates that the terminal is IN of the LADN service area.

### Claim 5

A method by a session management function (SMF) entity in a wireless communication system, the method comprising:
receiving, from an access and mobility management function (AMF) entity, a first message including information indicating whether a terminal is present in a local area data network (LADN) service area;
determining to subscribe to a terminal mobility event report service based on the first message;
transmitting, to the AMF entity, a second message including an LADN data network name (DNN); and
receiving, from the AMF entity, a third message for a mobility event report of a terminal associated with the LADN DNN,
wherein the first message is received, in case that a fourth message for requesting a protocol data unit (PDU) session establishment including a first LADN DNN is transmitted from the terminal to the AMF entity and the first LADN DNN is configured at the AMF entity as the LADN DNN.

### Claim 6 (depends on 5)

The method of claim 5, wherein the information indicates the terminal is IN or OUT of the LADN service area.

### Claim 7

An access and mobility management function (AMF) entity in a wireless communication system, the AMF entity comprising:
a transceiver; and
at least one processor configured to:
receive, from a terminal via the transceiver, a first message for requesting a protocol data unit (PDU) session establishment including a first local area data network (LADN) data network name (DNN),
determine whether the first LADN DNN is configured at the AMF entity as a LADN DNN,
determine whether the terminal is present in a LADN service area, in case that the first LADN DNN is configured at the AMF entity as the LADN DNN; and
transmit, to a session management function (SMF) entity via the transceiver, a second message indicating whether the terminal is present in the LADN service area.

### Claim 8 (depends on 7)

The AMF entity of claim 7, wherein the second message indicates the terminal is IN or OUT of the LADN service area.

### Claim 9 (depends on 7)

The AMF entity of claim 7, wherein the at least one processor is further configured to:
receive, from the SMF entity via the transceiver, information that the SMF entity subscribes to a terminal mobility event report service.

### Claim 10 (depends on 9)

The AMF entity of claim 9, wherein the information indicating that the SMF entity subscribes to the terminal mobility event report service in case that the second message indicates that the terminal is IN of the LADN service area.

### Claim 11

A session management function (SMF) entity in a wireless communication system, the SMF entity comprising:
a transceiver; and
at least one processor configured to:
receive, from an access and mobility management function (AMF) entity via the transceiver, a first message including information indicating whether a terminal is present in a local area data network (LADN) service area,
determine to subscribe to a terminal mobility event report service based on the first message,
transmit, to the AMF entity via the transceiver, a second message including an LADN data network name (DNN), and
receive, from the AMF entity, a third message for a mobility event report of a terminal associated with the LADN DNN,
wherein the first message is received, in case that a fourth message for requesting a protocol data unit (PDU) session establishment including a first LADN DNN is transmitted from the terminal to the AMF entity and the first LADN DNN is configured at the AMF entity as the LADN DNN.

### Claim 12 (depends on 11)

The SMF entity of claim 11, wherein the information indicates the terminal is IN or OUT of the LADN service area.
