Non-public network discovery, selection, and access control in vertical domain

An apparatus for a non-public network, the apparatus comprising:

• a memory interface to send or receive, to or from a memory device, data corresponding to a list of supported external service networks;
• and
• a processor to:
• generate a non-public network identifier (NID) configured to identify the non-public network and to indicate support of either an external service network or a local service;
• generate the list of supported external service networks, wherein the list comprises a plurality of service network identifiers (SN-IDs) corresponding to respective external service networks in the list, wherein a first SN-ID of the plurality of SN-IDs in the list with a PLMN identifier (PLMN-ID) format indicates support of a mobile network operator (MNO) providing PLMN services, and wherein a second SN-ID of the plurality of SN-IDs in the list comprises a domain name indicating support of a non-MNO;
• and
• broadcast information comprising the NID, the list of supported external service networks, and a non-public network indicator to differentiate between the non-public network and a public land mobile network (PLMN).

A method for a user equipment (UE), comprising:

• scanning frequency bands for a wireless wide area network (WWAN) and a non-public network (NPN);
• detecting a cell that supports the NPN based on an NPN indicator broadcast by the cell;
• in response to detecting the cell that supports the NPN, determining a network identifier (NID) for the NPN and a list comprising a plurality of service network identifiers (SN-IDs) supported by the NPN, wherein a first SN-ID of the plurality of SN-IDs in the list with a PLMN identifier (PLMN-ID) format indicates support of a mobile network operator (MNO) providing PLMN services, and wherein a second SN-ID of the plurality of SN-IDs in the list comprises a domain name indicating support of a non-MNO;
• and
• selecting the NPN to provide an external service or a local service based on at least one of the NID and the list of SN-IDs.
