## Abstract

The present disclosure describes methods, systems, and devices for configuring an enhanced non-public network (eNPN) for a new generation radio access network (NG-RAN). One method includes supporting, by a user equipment (UE), a network access feature by receiving, by the UE, a broadcast message from a RAN, wherein the broadcast message comprises at least one of the following: a group identifier (ID), a first indication, or a second indication. Another method includes supporting, by a UE, an eNPN by receiving, by the UE, an indication in a RRC signaling from a RAN, wherein the indication indicates whether to support at least one of the following for an non-public network: an internet protocol (IP) multimedia subsystem (IMS) voice, or an emergency call (eCall).

## Claims

### Claim 1

A method for wireless communication, comprising:
supporting, by a user equipment (UE), a network access feature corresponding to access to a stand-alone non-public network (SNPN) by:
receiving, by the UE, a broadcast message from a radio access network (RAN), wherein the broadcast message comprises:
a group identifier (ID) comprising at least one network ID,
a first indication indicating that access to the SNPN using credentials from an entity from the SNPN is supported, and
a second indication indicating whether the SNPN allows an access attempt from a UE that is not explicitly configured to select the SNPN; and
sending, by the UE through radio resource control (RRC) signaling, a third indication indicating a selected network ID, wherein the RRC signaling comprises an RRCSetupComplete message.

### Claim 2 (depends on 1)

The method according to claim 1, wherein:
the at least one network ID comprises at least one of the following:
a stand-along non-public network (SNPN) ID, or
a public land mobile network (PLMN) ID.

### Claim 3 (depends on 1)

The method according to claim 1, wherein:
the broadcast message comprises: the at least one group ID per cell, the first indication per network ID, and the second indication per network ID.

### Claim 4 (depends on 1)

The method according to claim 1, wherein:
the group ID comprises a group of network IDs of on-boarding networks.

### Claim 5 (depends on 1)

The method according to claim 1, wherein:
the group ID comprises a group of network IDs of subscription owners.

### Claim 6

A method for wireless communication, comprising:
supporting, by a radio access network (RAN), a network access feature corresponding to access to a stand-alone non-public network (SNPN) by:
broadcasting, by the RAN, a broadcast message to a user equipment (UE), wherein the broadcast message comprises:
a group identifier (ID) comprising at least one network ID,
a first indication indicating that access to the SNPN using credentials from an entity from the SNPN is supported, and
a second indication indicating whether the SNPN allows an access attempt from a UE that is not explicitly configured to select the SNPN; and
receiving, through radio resource control (RRC) signaling, a third indication indicating a selected network ID, wherein the RRC signaling comprises an RRCSetupComplete message.

### Claim 7 (depends on 6)

The method according to claim 6, wherein:
the at least one network ID comprises at least one of the following:
a stand-along non-public network (SNPN) ID, or
a public land mobile network (PLMN) ID.

### Claim 8 (depends on 6)

The method according to claim 6, wherein:
the broadcast message comprises: the at least one Group ID per cell, the first indication per network ID, and the second indication per network ID.

### Claim 9 (depends on 6)

The method according to claim 6, wherein:
the group ID comprises a group of network IDs of on-boarding networks.

### Claim 10 (depends on 6)

The method according to claim 6, wherein:
the group ID comprises a group of network IDs of subscription owners.

### Claim 11

An apparatus comprising:
a memory storing instructions; and
a processor in communication with the memory, wherein, when the processor executes the instructions, the processor is configured to cause the apparatus to perform:
supporting a network access feature corresponding to access to a stand-alone non-public network (SNPN) by:
receiving a broadcast message from a radio access network (RAN), wherein the broadcast message comprises:
a group identifier (ID) comprising at least one network ID,
a first indication indicating that access to the SNPN using credentials from an entity from the SNPN is supported, and
a second indication indicating whether the SNPN allows an access attempt from a UE that is not explicitly configured to select the SNPN; and
sending, through radio resource control (RRC) signaling, a third indication indicating a selected network ID, wherein the RRC signaling comprises an RRCSetupComplete message.

### Claim 12 (depends on 11)

The apparatus according to claim 11, wherein:
the at least one network ID comprises at least one of the following:
a stand-along non-public network (SNPN) ID, or
a public land mobile network (PLMN) ID.
