Abstract: Some embodiments relate to methods for provisioning a secondary wireless device with an eSIM for wireless communication and activating multi-SIM functionality between the secondary wireless device and a primary wireless device having a subscribed SIM. The primary wireless device may act as a proxy in obtaining the eSIM for the secondary wireless device. The primary wireless device may then provide, to the cellular network, identifiers of the SIMs of the primary and secondary wireless devices. The primary wireless device may then request initiation of multi-SIM functionality for the two SIMs, and receive an indication that the multi-SIM functionality has been initiated. As an example, the multi-SIM functionality may be implemented by mapping the SIM of the primary wireless device and the SIM of the secondary wireless device (e.g., the provisioned eSIM) to the same Mobile Directory Number (MDN).

Abstract: System and methods for providing special radio provisions to link budget limited devices. Before establishing a cellular connection with a cellular network, a user equipment device (UE), such as a link budget limited UE, may negotiate the special radio provisions with the network by presenting requested profile information to the network, and receiving back approved profile information from the network. The UE may perform these communications either directly, via a non-cellular communication connection with the network, or indirectly, via a companion or proxy device. When the UE initiates a cellular connection with the network, both entities may use information specified in the approved profile information, which may improve efficiency of the connection. In some scenarios, the approved profile information may identify a class of devices to which the UE belongs. The approved profile information may also be used in establishing connections with other devices of the same class.

Abstract: This disclosure relates to techniques for performing Wi-Fi authentication in a wireless communication system. Public key cryptography may be used to enhance the confidentiality of the user's permanent identity in transit. In some embodiments, a RSA-OAEP (SHA-256) encryption scheme may be used to protect the permanent identity when the EAP client needs to send the user's permanent identity to the server in the absence of pseudonym or fast re-authentication identity. In some embodiments, a server certificate is used to authenticate a iWLAN tunnel to protect an IMSI during setup of a Wi-Fi call. Using the methods described herein on both or either of the EAP client and server side may offer improved privacy protection.

Abstract: Techniques to manage updates for eSIMs of a secondary wireless device are disclosed. Responsive to a user input, expiration of a timer, receipt of a message from an associated primary wireless device, processing circuitry of the secondary wireless device commands an eUICC to update an eSIM. A secure data connection is established between the eUICC and a network provisioning server, either directly from the secondary wireless device to a cellular wireless network or relayed indirectly via the primary wireless device. The eUICC and the network provisioning server exchange messages in accordance with a BIP process to update the eSIM. The eUICC provides a status to the processing circuitry indicating success or failure for the eSIM update. Upon success, a portion of the secondary wireless device may be placed in a reduced power state. Upon failure, the eSIM update process may repeat up to a maximum number of retries.

Abstract: Distributing indications of emergency messages via Wi-Fi. A cellular device may temporarily disable its cellular modem. The cellular device may receive an indication over Wi-Fi that an emergency message has been broadcast. In response, the cellular device may activate its cellular modem and retrieve the emergency message via a cellular network.

Abstract: This Application describes mechanisms for enterprise remote management of cellular services provided via access credentials, e.g., subscriber identity modules (SIMs) and/or electronic SIMs (eSIMs), for wireless devices. To minimize requirements for user interaction, installation and management of business-supplied cellular service profiles on the wireless device can intercept alert notifications to reduce interruptions and allow for background management of the business-supplied cellular service profiles. Additionally, a business enterprise can use multiple, distinct services to initiate installation of an eSIM to a wireless device. When two different services attempt to install eSIMs on the wireless device in parallel, management software on the wireless device can control an order of installation and disallow duplicate installations of an identical eSIM to the wireless device. The management software can also monitor eSIM installations and manage alert notifications that occur during the eSIM installation process.

Abstract: The exemplary embodiments relate to a user equipment configured to connect to a network that supports simultaneous connection to a first radio access technology (RAT) and a second RAT. The UE may receive coverage information associated with the first RAT and a cell of the second RAT, receive an indication of the current UE location relative to the cell of the second RAT and determine whether the first RAT is available for camping based on the coverage information and the indication of the current UE location relative to the cell of the second RAT.
