Abstract: Apparatus and methods to transfer user preferences for cellular wireless service associated credentials transferred from a source device to a target device. Transfer of credentials can include physically moving a physical subscriber identity module (SIM) card between devices, transfer of cellular wireless service from a first SIM card at the source device to a second SIM card at the target device, and/or transfer of cellular wireless services for one or more electronic SIMs (eSIMs) from the source device to the target device. Preferences associated with some or all of the transferred SIMs/eSIMs can be applied at the target device when certain matching criteria are satisfied. Exemplary matching criteria include matching identifiers, such as integrated circuit card identifier (ICCID) values, mobile station international subscriber directory number (MSISDN) values, and/or mappings thereof. Transfer of preferences can occur via a local peer-to-peer connection, a secure cloud-based service, and/or a backup and restore process.

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.
