## Abstract

The present disclosure relates to a pre-5th-Generation (5G) or 5G communication system to be provided for supporting higher data rates Beyond 4th-Generation (4G) communication system such as Long Term Evolution (LTE). Embodiments herein disclose a method performed by a terminal in a mobile communication system. The method includes performing a registration procedure on a first standalone non-public network (SNPN), selecting a second SNPN based on a predetermined condition, and transmitting, to a network entity, a registration request message on the second SNPN for an initial registration, in case that the second SNPN differs from the first SNPN.

## Claims

### Claim 1

A method performed by a terminal in a mobile communication system, the method comprising:
performing a standalone non-public network (SNPN) selection;
identifying a new SNPN being selected based on the SNPN selection; and
based on the identification, resetting a registration attempt counter and initiating a registration procedure for an initial registration,
wherein the initiating of the registration procedure for the initial registration further comprises transmitting, to a network entity, a registration request message including information on a registration type, and
wherein the information on the registration type indicates the initial registration.

### Claim 2 (depends on 1)

The method of claim 1, wherein the network entity is an access and mobility management function (AMF).

### Claim 3 (depends on 1)

The method of claim 1, wherein the terminal is configured with a list of subscriber data including an SNPN identity and the SNPN selection is performed based on the list of subscriber data.

### Claim 4 (depends on 1)

The method of claim 1, wherein the SNPN selection is performed in case that the terminal recovers from a lack of coverage.

### Claim 5 (depends on 1)

The method of claim 1, wherein the SNPN selection is performed using an automatic SNPN selection mode procedure.

### Claim 6 (depends on 1)

The method of claim 1, wherein the SNPN selection is performed using a manual SNPN selection mode procedure.

### Claim 7

A terminal in a mobile communication system, the terminal comprising:
a transceiver; and
a controller operably connected to the transceiver, the controller configured to:
perform a standalone non-public network (SNPN) selection,
identify a new SNPN being selected based on the SNPN selection, and
based on the identification, reset a registration attempt counter and initiate a registration procedure for an initial registration by transmitting, to a network entity via the transceiver, a registration request message including information on a registration type,
wherein the information on the registration type indicates the initial registration.

### Claim 8 (depends on 7)

The terminal of claim 7, wherein the network entity is an access and mobility management function (AMF).

### Claim 9 (depends on 7)

The terminal of claim 7, wherein the terminal is configured with a list of subscriber data including an SNPN identity and the SNPN selection is performed based on the list of subscriber data.

### Claim 10 (depends on 7)

The terminal of claim 7, wherein the SNPN selection is performed in case that the terminal recovers from a lack of coverage.

### Claim 11 (depends on 7)

The terminal of claim 7, wherein the SNPN selection is performed using an automatic SNPN selection mode procedure.

### Claim 12 (depends on 7)

The terminal of claim 7, wherein the SNPN selection is performed using a manual SNPN selection mode procedure.
