Patent Description:
"<NPL>, relates to a technical report describing relevant use-cases and proposes respective potential service requirements for <NUM> systems to support production of audio-visual (AV) content and services, in particular via a network deployed as non-public network (NPN). This document raises the question of how provisioning of the broadcaster's equipment is done, and how agile the process can be in a rapidly changing production environment. It can be expected that the equipment brought onsite by the broadcasters do not have the credentials of the Non-Public Network (NPN). It can be assumed, however, that this heterogeneous equipment has been provisioned correctly to work with the Broadcaster. In this scenario, the NPN is required to be able to advertise the broadcaster which have been enabled on the NPN. Alternatively, the equipment brought onsite by the broadcasters already have installed the subscriptions and credentials of a PLMN which has agreement with the Non-Public Network (NPN). The agreement allows the equipment that have subscriptions with the PLMN to access the services provided by the NPN as well as PLMN via NPN (in MVNO- or roaming-like scenario). As such, the equipment can get access to NPN/PLMN services via a non-public network access by using a single subscription (i.e. the PLMN subscription) and a single set of credentials (i.e. the PLMN credentials).

<CIT> relates to techniques and apparatuses for managing communications in a private wireless network.

<NPL>, is a work item to support non-public network (NPN) for NG-RAN.

<NPL>, relates to a change request for CR to TS <NUM> for Identification, Network Selection and Unified AccessControl for NPN.

In the example shown in <FIG>, a relay base station 110d may communicate with macro BS 110a and a UE 120d in order to facilitate communication between BS 110a and UE 120d. A relay base station may also be referred to as a relay BS, a relay station, a relay, and/or the like.

Controller/processor <NUM> of base station <NUM>, controller/processor <NUM> of UE <NUM>, and/or any other component(s) of <FIG> may perform one or more techniques associated with standalone non-public network (SNPN) access, as described in more detail elsewhere herein. For example, controller/processor <NUM> of base station <NUM>, controller/processor <NUM> of UE <NUM>, and/or any other component(s) of <FIG> may perform or direct operations of, for example, process <NUM> of <FIG>, and/or other processes as described herein. Memories <NUM> and <NUM> may store data and program codes for base station <NUM> and UE <NUM>, respectively. In some aspects, memory <NUM> and/or memory <NUM> may comprise a non-transitory computer-readable medium storing one or more instructions for wireless communication. For example, the one or more instructions, when executed by one or more processors of the base station <NUM> and/or the UE <NUM>, may perform or direct operations of, for example, process <NUM> of <FIG> and/or other processes as described herein.

In some aspects, UE <NUM> may include means for determining whether an SNPN, to which the UE <NUM> is not subscribed, permits access to subscribers of a network to which the UE <NUM> is subscribed, means for registering with the SNPN based at least in part on a determination that the SNPN permits access to subscribers of the network to which the UE is subscribed, and/or the like. In some aspects, such means may include one or more components of UE <NUM> described in connection with <FIG>, such as controller/processor <NUM>, transmit processor <NUM>, TX MIMO processor <NUM>, MOD <NUM>, antenna <NUM>, DEMOD <NUM>, MIMO detector <NUM>, receive processor <NUM>, and/or the like.

An SNPN is a dedicated, private wireless network (e.g., a <NUM> network) that may be associated with an enterprise, a facility, and/or a site. For example, an SNPN may be associated with a particular corporate campus, a particular factory, a particular industrial facility, and/or the like. Access to an SNPN may be limited to UEs having subscriptions to the SNPN. However, a UE that is not subscribed to the SNPN may lack information on the SNPN, such as information indicating whether the SNPN is a public or a non-public network, whether the SNPN permits access to subscribers of other networks, and/or the like. Accordingly, the UE, when in the SNPN's coverage area, may attempt to register with the SNPN even if the UE will not be permitted access, thereby consuming computing resources, network resources, and/or the like.

Some techniques and apparatuses described herein enable a UE to determine whether the UE may access an SNPN using a subscription for another network. For example, the UE may determine whether the UE may access an SNPN using a subscription for another network prior to attempting registration with the SNPN. In this way, the UE and/or the SNPN may conserve computing resources, network resources, and/or the like, that may otherwise be used in a registration attempt that will not be permitted.

<FIG> are diagrams illustrating examples <NUM>, <NUM>, and <NUM> of SNPN access, in accordance with various aspects of the present disclosure. As shown in <FIG>, a UE <NUM> may communicate with a BS <NUM> in connection with accessing an SNPN. The BS <NUM> may be associated with a radio access network of one or more SNPNs. In some aspects, the UE <NUM> may not be subscribed to the one or more SNPNs, and thus, each of the one or more SNPNs may be referred to as a visited-SNPN (V-SNPN) relative to the UE <NUM>. In addition, an SNPN may be associated with an identifier, such as an identifier formed from a combination of a public land mobile network (PLMN) identifier and a network identifier.

In some aspects, the UE <NUM> may be subscribed to one or more other wireless networks (e.g., one or more PLMNs, one or more other SNPNs, and/or the like), and thus, each of the one or more other wireless networks may be referred to as a home service provider (SP) relative to the UE <NUM>. A wireless network (e.g., a home SP) may be associated with an identifier, such as a PLMN identifier (in the case of a PLMN), an identifier formed from a combination of a PLMN identifier and a network identifier (in the case of an SNPN), and/or a domain name (in the case of an SNPN).

In some aspects, the UE <NUM> may determine whether an SNPN (e.g., a V-SNPN), to which the UE is not subscribed, permits access to subscribers of a network (e.g., a home SP) to which the UE is subscribed, according to one or more procedures. Example <NUM> of <FIG> shows a UE configuration-based procedure for determining whether an SNPN permits access to subscribers of another network. Example <NUM> of <FIG> shows a network broadcast-based procedure for determining whether an SNPN permits access to subscribers of another network. Example <NUM> of <FIG> shows a UE request-based procedure for determining whether an SNPN permits access to subscribers of another network. In some aspects, the UE <NUM> may be operating in an SNPN-access mode in order to enable discovery of SNPNs. In some aspects, the BS <NUM> may transmit (e.g., broadcast) an indication (e.g., a single-bit indication) of whether an SNPN associated with the BS <NUM> permits access to subscribers of other wireless networks.

As shown in <FIG>, and by reference number <NUM>, the BS <NUM> may transmit, and the UE <NUM> may receive, a communication that includes an SNPN identifier (e.g., a combination of a PLMN identifier and a network identifier) for an SNPN (e.g., a V-SNPN) associated with the BS <NUM>. In the claimed invention, the communication is a broadcast communication. For example, the communication may be included in a system information block (SIB) transmitted by the BS <NUM>. The communication includes multiple SNPN identifiers corresponding, respectively, to multiple SNPNs associated with the BS <NUM>.

As shown by reference number <NUM>, the UE <NUM> may compare the received SNPN identifier to a set (e.g., one or more) of SNPN identifiers stored by the UE <NUM>. In some aspects, the UE <NUM> may have a configuration for the set of SNPN identifiers. The configuration may identify a priority order for the set of SNPN identifiers. In addition, the configuration may be associated with a subscription of the UE <NUM> to a wireless network (e.g., a home SP). Accordingly, the set of SNPN identifiers may correspond to respective SNPNs (e.g., V-SNPNs) that permit access to subscribers of the subscribed wireless network. In some aspects, the UE <NUM> may have multiple configurations (e.g., for respective subscriptions of the UE <NUM>) that include respective sets of SNPN identifiers, and the UE <NUM> may compare the received SNPN identifier to each set of SNPN identifiers.

In some aspects, the UE <NUM> may receive a configuration from a wireless network (e.g., a home SP) to which the UE <NUM> is subscribed. For example, the UE <NUM> may receive a configuration from a base station of the wireless network, such as via non-access stratum (NAS) messaging. The UE <NUM> may receive the configuration upon subscribing to the wireless network, or periodically, such as when updates to the set of SNPN identifiers occur. In some other aspects, a subscriber identity module (SIM) card or a universal integrated circuit card (UICC) coupled to the UE <NUM> may include a configuration.

In some aspects, the UE <NUM> may compare the received SNPN identifier to a set of SNPN identifiers stored by the UE <NUM> in order to determine whether the SNPN (associated with the SNPN identifier), to which the UE <NUM> is not subscribed, permits access to subscribers of a wireless network to which the UE <NUM> is subscribed. For example, if the received SNPN identifier corresponds to an SNPN identifier in the set of SNPN identifiers (associated with a subscription of the UE <NUM>), the UE <NUM> may determine that the SNPN (associated with the SNPN identifier) permits access to subscribers of the subscribed wireless network (e.g., a home SP). Accordingly, the UE <NUM> may determine that a subscription of the UE <NUM> for the subscribed wireless network may be used to access the SNPN (e.g., a V-SNPN), and may select the subscription and the SNPN for registration. In some cases, the received SNPN identifier may correspond to SNPN identifiers in different sets of SNPN identifiers (associated with different subscriptions of the UE <NUM>). In such a case, the UE <NUM> may select one subscription for registration.

In the claimed invention, the UE <NUM> receives a plurality of SNPN identifiers from the BS <NUM>, the UE <NUM> determines that multiple received SNPN identifiers correspond to multiple SNPN identifiers in a set of SNPN identifiers stored by the UE <NUM>. Accordingly, the UE <NUM> determines that multiple SNPNs (associated with the multiple SNPN identifiers) permit access to subscribers of a wireless network (e.g., a home SP) to which the UE <NUM> is subscribed. In such a case, the UE <NUM> determines that a subscription of the UE <NUM> for the subscribed wireless network may be used to access the multiple SNPNs (e.g., V-SNPNs), and may select the subscription and one SNPN from the multiple SNPNs for registration. For example, the UE <NUM> selects the SNPN according to a priority order of the set of SNPN identifiers: in the claimed invention, an SNPN associated with an SNPN identifier having a highest priority among the set of SNPN identifiers is selected.

In some other aspects, such as when the UE <NUM> receives a plurality of SNPN identifiers from the BS <NUM>, the UE <NUM> may determine that multiple received SNPN identifiers correspond to SNPN identifiers in different sets of SNPN identifiers (associated with different subscriptions of the UE <NUM>) stored by the UE <NUM>. Accordingly, the UE <NUM> may determine that multiple subscriptions of the UE <NUM> may be used, respectively, to access the multiple SNPNs (e.g., V-SNPNs), and may select one subscription and corresponding SNPN for registration.

As shown by reference number <NUM>, the UE <NUM> may perform a registration procedure with the SNPN (e.g., the selected SNPN) based at least in part on a determination that the SNPN permits access to subscribers of a subscribed wireless network of the UE <NUM>. For example, the UE <NUM> may perform the registration procedure based at least in part on a determination that a subscription (e.g., a selected subscription) of the UE <NUM> for a wireless network may be used to access the SNPN. Accordingly, the UE <NUM> may transmit, and the BS <NUM> may receive, a registration request. In some aspects, the registration request may identify an SNPN identifier of the selected SNPN. In addition, the registration request may include a subscription permanent identifier (SUPI) of the UE <NUM> for the subscribed wireless network and/or other credentials of the UE <NUM> relating to a subscription for the wireless network. In some aspects, the SUPI may be in a concealed form, such as a subscription concealed identifier (SUCI). Based on receiving the registration request, the BS <NUM> may cause communication between the SNPN (e.g., V-SNPN) and the subscribed wireless network (e.g., home SP) to effect registration of the UE <NUM> on the SNPN.

As shown in <FIG>, and by reference number <NUM>, the BS <NUM> may transmit, and the UE <NUM> may receive, a communication that includes a set (e.g., one or more) of network identifiers corresponding to respective wireless networks (e.g., home SPs) of which subscribers are permitted to access an SNPN (e.g., a V-SNPN) associated with the BS <NUM>. A network identifier may be a PLMN identifier (in a case when the wireless network is a PLMN), a combination of a PLMN identifier and network identifier (in a case when the wireless network is an SNPN), and/or a domain name (in a case when the wireless network is an SNPN). In some aspects, a network identifier may be a shortened network identifier that corresponds to a full network identifier for a wireless network. For example, the network identifier may be a hash value of the full network identifier.

In some aspects, the communication (or multiple communications) may include multiple sets of network identifiers corresponding, respectively, to multiple SNPNs associated with the BS <NUM> (e.g., when a cell is shared by multiple SNPNs). In some aspects, the communication may be a broadcast communication. For example, the communication may be included in a SIB transmitted by the BS <NUM>.

As shown by reference number <NUM>, the UE <NUM> may compare the received set of network identifiers to a stored network identifier associated with a wireless network (e.g., a home SP) to which the UE <NUM> is subscribed. For example, the UE <NUM> may be configured with a SUPI for the subscribed wireless network. In some aspects, the UE <NUM> may compare the received set of network identifiers to a portion of the SUPI that identifies a wireless network (e.g., a PLMN identifier portion of the SUPI, a PLMN identifier and network identifier portion of the SUPI, and/or a domain name portion of the SUPI). In some aspects, the UE <NUM> may be subscribed to multiple wireless networks (e.g., multiple home SPs), and may be configured with respective network identifiers (e.g., SUPIs) for the multiple subscribed wireless networks. In such cases, the UE <NUM> may compare the received set of network identifiers to the network identifier for each wireless network subscription of the UE <NUM>.

In some aspects, such as when the set of network identifiers is a set of shortened network identifiers, the UE <NUM> may process (e.g., using a mapping) a network identifier (e.g., a portion of a SUPI) associated with a subscribed wireless network in order to determine a shortened network identifier. For example, the UE <NUM> may process the network identifier with a hash function in order to determine a shortened network identifier. The UE <NUM> may then compare the set of shortened network identifiers to the determined shortened network identifier, as described above.

In some aspects, the UE <NUM> may compare the received set of network identifiers to a network identifier associated with a wireless network to which the UE <NUM> is subscribed in order to determine whether the SNPN (associated with the set of network identifiers), to which the UE <NUM> is not subscribed, permits access to subscribers of a wireless network to which the UE <NUM> is subscribed. For example, if a network identifier associated with a subscribed wireless network (e.g., a home SP) corresponds to a network identifier in a set of network identifiers received by the UE <NUM>, the UE <NUM> may determine that the SNPN (associated with the set of network identifiers) permits access to subscribers of the subscribed wireless network. Accordingly, the UE <NUM> may determine that a subscription of the UE <NUM> for the subscribed wireless network may be used to access the SNPN (e.g., a V-SNPN), and may select the subscription and the SNPN for registration.

In some aspects, such as when the UE <NUM> receives a plurality of sets of network identifiers from the BS <NUM>, the UE <NUM> may determine that a network identifier, associated with a subscription of the UE <NUM>, corresponds to network identifiers in different received sets of network identifiers. Accordingly, the UE <NUM> may determine that multiple SNPNs (associated with the different sets of network identifiers) permit access to subscribers of a wireless network (e.g., a home SP) to which the UE <NUM> is subscribed. Accordingly, the UE <NUM> may determine that a subscription of the UE <NUM> for the subscribed wireless network may be used to access the multiple SNPNs (e.g., V-SNPNs), and may select the subscription, and one SNPN from the multiple SNPNs, for registration.

In some other aspects, such as when the UE <NUM> receives a plurality of sets of network identifiers from the BS <NUM>, the UE <NUM> may determine that multiple network identifiers, associated with multiple subscriptions of the UE <NUM>, correspond to network identifiers in different received sets of network identifiers. Accordingly, the UE <NUM> may determine that multiple SNPNs (associated with the different sets of network identifiers) permit access to subscribers of more than one wireless network (e.g., home SPs) to which the UE <NUM> is subscribed. Accordingly, the UE <NUM> may determine that multiple subscriptions of the UE <NUM> for the subscribed wireless networks may be used, respectively, to access the multiple SNPNs (e.g., V-SNPNs), and may select one subscription and corresponding SNPN for registration.

As shown by reference number <NUM>, the UE <NUM> may perform a registration procedure with the SNPN (e.g., the selected SNPN) based at least in part on a determination that the SNPN permits access to subscribers of a subscribed wireless network, as described above in connection with <FIG>.

As shown in <FIG>, and by reference number <NUM>, the BS <NUM> may transmit, and the UE <NUM> may receive, a communication indicating support for requests to receive access information from an SNPN (e.g., a V-SNPN) associated with the BS <NUM>. In some aspects, the communication (or multiple communications) may indicate support for requests to receive access information from multiple SNPNs associated with the BS <NUM> (e.g., when a cell is shared by multiple SNPNs). In such a case, the communication may include respective SNPN identifiers of the multiple SNPNs that support requests. In some aspects, the communication may be a broadcast communication. For example, the communication may be included in a SIB transmitted by the BS <NUM>.

As shown by reference number <NUM>, the UE <NUM> may transmit, and the BS <NUM> may receive, a communication that includes a request to receive access information from the SNPN. For example, the UE <NUM> may transmit the request based at least in part on receiving the communication indicating support for requests to receive access information from the SNPN. In some aspects, the request may include an SNPN identifier of an SNPN from which the UE <NUM> is requesting to receive access information. The requested access information may relate to a set of network identifiers corresponding to respective wireless networks (e.g., home SPs) of which subscribers are permitted to access the SNPN.

As shown by reference number <NUM>, the BS <NUM> may transmit, and the UE <NUM> may receive, a communication that includes a set (e.g., one or more) of network identifiers corresponding to respective wireless networks (e.g., home SPs) of which subscribers are permitted to access the SNPN (e.g., V-SNPN). That is, the BS <NUM> may transmit the communication as a response to the request to receive access information transmitted by the UE. In some aspects, such as when the UE <NUM> requests to receive access information from multiple SNPNs, the communication (or multiple communications) may identify multiple sets of network identifiers.

In some aspects, the request (transmitted by the UE <NUM>) and the response (transmitted by the BS <NUM>) may be NAS messages (e.g., unauthenticated or authenticated NAS messages). Additionally, or alternatively, the request (transmitted by the UE <NUM>) and the response (transmitted by the BS <NUM>) may be radio resource control (RRC) messages. Additionally, or alternatively, the request (transmitted by the UE <NUM>) may be a system information request message and the response (transmitted by the BS <NUM>) may be an on-demand SIB message. In some aspects, the request may be one of a NAS message, RRC message, or system information request message, and the response may be another of a NAS message, RRC message, or on-demand SIB message.

As shown by reference number <NUM>, the UE <NUM> may compare the received set of network identifiers to a network identifier associated with a wireless network to which the UE <NUM> is subscribed, as described above in connection with <FIG>. For example, the UE <NUM> may compare the received set of network identifiers to a network identifier associated with a wireless network to which the UE <NUM> is subscribed in order to determine whether the SNPN (associated with the set of network identifiers), to which the UE <NUM> is not subscribed, permits access to subscribers of a wireless network to which the UE <NUM> is subscribed.

As shown by reference number <NUM>, the UE <NUM> may perform a registration procedure with the SNPN based at least in part on a determination that the SNPN permits access to subscribers of a subscribed wireless network, as described above in connection with <FIG>.

<FIG> are diagrams illustrating examples <NUM>, <NUM>, and <NUM> of SNPN access, in accordance with various aspects of the present disclosure. In particular, <FIG> show communications between components (e.g., implementing various network functions) of a subscribed wireless network (e.g., a home SP) and an SNPN (e.g., a V-SNPN) in connection with a registration procedure of a UE (e.g., UE <NUM>). Accordingly, as part of the registration procedure of the UE, the SNPN (e.g., one or more devices and/or components implementing the SNPN) may establish a connection to the subscribed wireless network (e.g., one or more devices and/or components implementing the subscribed wireless network). For example, based at least in part on an identifier provided by the UE as part of a registration procedure (e.g., a SUPI, a SUCI, and/or the like), as described above, a device implementing one or more components of the SNPN may determine an identity of the subscribed wireless network and, accordingly, may determine an address (e.g., using a mapping) at which the subscribed wireless network is reachable.

As shown in <FIG>, the SNPN may communicate with the subscribed wireless network to perform authentication of the UE and obtain subscription information for the UE. In particular, an access and mobility management function (AMF) of the SNPN may communicate with an authentication server function (AUSF) of the subscribed wireless network to authenticate the UE. For example, the AMF may transmit credentials of the UE that were provided with a registration request of the UE, as described above in connection with <FIG>. In addition, the AMF and a session management function (SMF) of the SNPN may communicate with a unified data management (UDM) function of the subscribed wireless network to obtain subscription information for the UE. For example, the AMF and/or the SMF may transmit an identifier of the UE (e.g., a SUPI or a SUCI) that was provided with a registration request of the UE, as described above in connection with <FIG>. As shown in <FIG>, after registration, the UE may communicate with a data network (e.g., a data network providing non-public network services, and/or the like) via a user plane function (UPF) of the SNPN.

As shown in <FIG>, the SNPN may communicate with the subscribed wireless network to perform authentication of the UE and obtain subscription information for the UE, as described above. In particular, an AMF of the SNPN may communicate with an AUSF of the subscribed wireless network to authenticate the UE, as described above. In addition, the AMF may communicate with a UDM component of the subscribed wireless network to obtain subscription information for the UE, as described above. As shown in <FIG>, after registration, the UE may communicate with a data network (e.g., the Internet) via the subscribed wireless network. For example, a UPF of the SNPN may forward a session (e.g., a physical data unit (PDU) session) of the UE to a UPF of the subscribed wireless network for termination at the data network via the subscribed wireless network.

As shown in <FIG>, the SNPN may communicate with the subscribed wireless network to perform authentication of the UE and obtain subscription information for the UE, as described above. In particular, an AMF of the SNPN may communicate with an AUSF of the subscribed wireless network to authenticate the UE, as described above. In addition, the AMF and an SMF of the SNPN may communicate with a UDM component of the subscribed wireless network to obtain subscription information for the UE, as described above. As shown in <FIG>, after registration, the UE may communicate with a data network (e.g., the Internet) via a UPF of the SNPN. As further shown in <FIG>, the UE may establish a tunnel, via the data network, to an inter-working function (IWF, shown as N3IWF) of the subscribed wireless network, thereby enabling the UE to access a data network (e.g., for file retrieval) via the UPF of the subscribed wireless network.

<FIG> is a diagram illustrating an example process <NUM> performed, for example, by a UE, in accordance with various aspects of the present disclosure. Example process <NUM> is an example where a UE (e.g., UE <NUM> and/or the like) performs operations associated with SNPN access.

As shown in <FIG>, in some aspects, process <NUM> may include determining whether an SNPN, to which a UE is not subscribed, permits access to subscribers of a network to which the UE is subscribed (block <NUM>). For example, the UE (e.g., using antenna <NUM>, DEMOD <NUM>, MIMO detector <NUM>, receive processor <NUM>, controller/processor <NUM>, and/or the like) may determine whether an SNPN, to which the UE is not subscribed, permits access to subscribers of a network to which the UE is subscribed, as described above.

As further shown in <FIG>, in some aspects, process <NUM> may include registering with the SNPN based at least in part on a determination that the SNPN permits access to subscribers of the network to which the UE is subscribed (block <NUM>). For example, the UE (e.g., using controller/processor <NUM>, transmit processor <NUM>, TX MIMO processor <NUM>, MOD <NUM>, antenna <NUM>, and/or the like) may register with the SNPN based at least in part on a determination that the SNPN permits access to subscribers of the network, as described above.

In a first aspect, determining whether the SNPN permits access to subscribers of the network includes receiving a communication that includes an SNPN identifier, and comparing the SNPN identifier to a set of SNPN identifiers corresponding to respective SNPNs that permit access to subscribers of the network. In a second aspect, alone or in combination with the first aspect, process <NUM> further includes receiving, from a base station of the network, a configuration for the set of SNPN identifiers prior to determining whether the SNPN permits access to subscribers of the network.

In a third aspect, alone or in combination with one or more of the first and second aspects, determining whether the SNPN permits access to subscribers of the network includes receiving a communication that includes one or more network identifiers corresponding to respective networks of which subscribers are permitted access to the SNPN, and comparing an identifier of the network to the one or more network identifiers. In a fourth aspect, alone or in combination with one or more of the first through third aspects, the one or more network identifiers are shortened network identifiers that correspond to full network identifiers of the respective networks, and the identifier of the network is a shortened identifier that corresponds to a full network identifier of the network. In a fifth aspect, alone or in combination with one or more of the first through fourth aspects, the communication is a broadcast communication.

In a sixth aspect, alone or in combination with one or more of the first through fifth aspects, process <NUM> further includes transmitting a request to receive the one or more network identifiers, where the communication that includes the one or more network identifiers is a response to the request. In a seventh aspect, alone or in combination with one or more of the first through sixth aspects, process <NUM> further includes receiving, prior to transmitting the request, another communication that indicates support for requests to receive the one or more network identifiers. In an eighth aspect, alone or in combination with one or more of the first through seventh aspects, the request is a first unauthenticated NAS message, a first authenticated NAS message, a first RRC message, or a system information request message, and the response is a second unauthenticated NAS message, a second authenticated NAS message, a second RRC message, or a SIB message.

In a ninth aspect, alone or in combination with one or more of the first through eighth aspects, a plurality of SNPNs are determined to permit access to subscribers of the network, and process <NUM> further includes selecting the SNPN with which the UE is to register from the plurality of SNPNs. In a tenth aspect, alone or in combination with one or more of the first through ninth aspects, the SNPN is associated with an SNPN identifier having a highest priority among a set of SNPN identifiers associated with the plurality of SNPNs.

In an eleventh aspect, alone or in combination with one or more of the first through tenth aspects, a first SNPN is determined to permit access to subscribers of a first network and a second SNPN is determined to permit access to subscribers of a second network, and process <NUM> further includes selecting the first SNPN or the second SNPN as the SNPN with which the UE is to register.

In a twelfth aspect, alone or in combination with one or more of the first through eleventh aspects, registering with the SNPN includes transmitting a subscription identifier associated with the network.

In fact, many of these features may be combined in ways not specifically recited in the claims and/or disclosed in the specification, without however departing from the scope of the invention as defined in the appended claims.

Claim 1:
A method (<NUM>) of wireless communication performed by a user equipment, UE, the method (<NUM>) comprising:
