Abstract: Aspects of the disclosure provide methods and apparatuses. The method can include receiving, at a user equipment (UE), system information broadcast from one or more base stations which may be shared by one or more PLMNs and/or one or more SNPNs, the system information including an indication of whether accessing an SNPN using home service provider (HSP) subscription of a HSP network is supported. The UE can be configured with subscription information of the HSP network. The subscription information can include the HSP subscription and a selection list that includes one or more candidate networks each represented by an SNPN identifier. The method can further include responsive to the system information, selecting a network from the selection list according to a priority order of the candidate networks, and accessing the network selected from the selection list using the HSP subscription.

Abstract: Various solutions for enhanced closed access group (CAG) selection in manual network selection mode are described. An apparatus may determine that the apparatus supports CAG and operates in a manual network selection mode. The apparatus may detect a CAG cell associated with a CAG identifier (ID) in an allowed CAG list. The apparatus may indicate to a user whether the CAG ID is authorized based on time validity information associated with the CAG ID in the allowed CAG list.

Abstract: A method of subscription selection for manual SNPN hosting network selection is proposed. When a UE supports accessing NPN, the UE has a 1st SNPN/PLMN subscription for accessing a selected SNPN as hosting network for localized services. If the selected SNPN is associated with validity information and validity criteria are met, the UE can register to the selected SNPN using the 1st subscription. If the UE has multiple subscriptions that can be used to access to the selected SNPN, then the UE can register to the selected SNPN using any of the subscriptions. The UE may determine which subscription to use based on whether the validity information associated with the selected SNPN that is included in the corresponding subscription, e.g., whether the selected SNPN is associated with validity information, and how long is the remaining (time) duration of the validity information.

Abstract: A method of handling authentication reject upon accessing an SNPN using credentials from a credential holder is proposed. A UE is configured with a “list of subscriber data”. The UE selects an SNPN using the configured list of subscriber data, e.g., based on the SNPN selection parameters contained in a selected entry of the list of subscriber data. Based on the selected entry, the UE selects an SNPN, and then tries to access the selected SNPN using credentials supplied by a subscribed SNPN. When UE receives an authentication reject message from the network, UE considers that the selected entry of the list of subscriber data is invalid. However, other entries related to the current selected SNPN are still valid. UE is still able to access the current selected SNPN, using credentials supplied in another entry of the list of subscriber data.

Abstract: A method supporting enhanced network identity (NID) provisioning under User Equipment (UE) mobility scenarios between different types of networks is proposed. When a UE registers to an SNPN, the UE is assigned with a 5G-GUTI by the SNPN. The SNPN is identified by an SNPN ID==PLMN ID+NID. When the UE moves from the SNPN to another target network having a target AMF, the UE triggers a mobility registration update procedure and provides the 5G-GUTI along with NID information in a Registration Request to the target AMF. The target AMF can use the NID information along with the 5G-GUTI to find a source AMF for deriving UE context for the subsequent operations during the mobility registration update procedure. Providing NID information along with 5G-GUTI can assist the target AMF to find the source AMF efficiently, preventing a potential registration procedure failure.

Abstract: In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. The method may be performed by a mobile device. In certain configurations, the mobile device registers a first network access of a first public land mobile network (PLMN). After registering to the first network access, the mobile device determines, based on first information, whether a second network access of a PLMN or a Standalone Non-Public Network (SNPN) is allowed for the UE to register thereto. In response to determining the second network access is allowed, the mobile device selects the second network access based on the first information, and registers to the second network access. The second network access may be a network access of the first PLMN, or may be a network access of a second different PLMN or the SNPN.

Abstract: A method of handling a service request from a UE camped on a CAG cell with emergency PDU session is proposed, where the UE is not authorized to access the current CAG cell. When the UE-maintained CAG related configuration is not synchronized with the NW-maintained CAG related configuration, the UE may try to access a CAG cell and sends a service request, but the NW may determine that the CAG cell is not suitable. Because the UE has an existing emergency PDU session, the network will accept the service request, and locally releases all non-emergency PDU sessions associated with 3GPP access. Specifically, the network will locally release SA non-emergency PDU sessions associated with 3GPP access, or MA PDU sessions with only 3GPP access user-plane resources, or 3GPP user-plane resources of MA PDU sessions with both 3GPP and non-3GPP access user-plane resources.

Abstract: A method of handling deregistration procedure with updated a CAG related configuration is proposed. From the network perspective, an AMF receives a DEREGISTRATION REQUEST message from a UE in a CAG cell that broadcasts a list of supported CAG-IDs. The AMF determines that a CAG-ID is supported by the CAG cell and included in the CAG related configuration of the UE. However, the CAG-ID is associated with validity or restriction information, and the corresponding validity or restriction criteria are not met. In response to the UE-initiated DEREGISTRATION REQUEST message, the AMF initiates a de-registration procedure and send a network-initiated DEREGISTRATION REQUEST message to the UE, including a 5GMM cause value. The network-initiated DEREGISTRATION REQUEST message can also include the updated CAG related configuration for UE. Upon receiving the DEREGISTRATION REQUEST message, the UE can update the UE-maintained CAG related configuration accordingly.

Abstract: A method for PLMN selection when UE supports accessing CAG/PNI-NPN as hosting network for localized services is proposed. When a UE is registered to a first PLMN as a non-hosting network, a cell of a second PLMN may become available for localized service. The UE can select and register to a second PLMN as a hosting network even if the second PLMN has a lower PLMN priority than the first PLMN based on traditional PLMN priority order. If multiple PLMNs are available for localized services, then the UE can select and register to a PLMN based on priority information for hosting network. The priority information for hosting network can be 1) reusing traditional PLMN priority order; 2) a new configuration for hosting network selection priority; 3) based on validity information.

Abstract: A method of a UE determining whether a current camped CAG cell is suitable and thereby entering limited service state for PNI-NPN as a hosting network is provided. When the PNI-NPN is a hosting network providing localized services, one or more allowed CAG IDs are associated with validity information per UE stored configuration, e.g., time and/or location validity criteria. Once a CAG cell is selected and camped by the UE in a PLMN, the UE needs to consider whether the current CAG cell is suitable for obtaining normal service from the PLMN. If the hosting network functionality is not enabled (by user), or if the time and/or location validity criteria associated with CAG-IDs broadcasted by the current CAG cell are not met, then the current CAG cell is not suitable. As a result, the UE enters limited service state, and triggers cell reselection or PLMN selection procedure.
