Abstract: Various aspects of the present disclosure relate to temporary identifiers for devices in a group. A device receives a group inventory request that includes a group identifier (ID) and a correlation ID. The device generates a temporary ID for the device based at least in part on the correlation ID and an individual ID of the device, and transmits an inventory response that includes the temporary ID for the device and the correlation ID. The device can receive a command request that includes a second temporary ID, perform, based at least in part on the second temporary ID matching the temporary ID of the device, a command indicated by the command request, and transmit a command response message that includes the second temporary ID.

Abstract: Various aspects of the present disclosure relate to providing a network with information about the capabilities of UEs, so the network can send extended information (e.g., extended SOR-SNPN-SI) to UEs that can handle and properly utilize such information. For example, a UE can provide its 5GMM capability information to the network during a registration procedure, and in response, the network can provide lists of SNPNs/GINs, which can include the extended information (e.g., via various container IE configurations).

Abstract: Apparatuses, methods, and systems are disclosed for providing subscription data for an external subscriber. One apparatus includes a processor and a network interface that receives a registration request message from a remote unit and receives a subscription retrieval information.

The processor controls the network interface to transmit to a network function in a mobile communication network a first request for subscription data retrieval using the subscription retrieval information and receive a response message from the network function that contains the UE subscription data. Here, the subscription retrieval information indicates that the subscription data is stored in a subscription owner outside the mobile communication network.
