Abstract
An MVNO utilizes MNVO-controlled equipment to control generation of public-private key pairs, provisioning of user devices using a public-private key pair, and authenticating user devices requesting access to an MVNO network using the public-private key pair. An MNVO-controlled provisioning server can use a key of a public-private key pair to encrypt a SIM-based identity that is associated with a user device. When the user device requests access to an MVNO network, an MNVO-controlled authentication server requests an encrypted SIM-based identity from the user device and uses a key to decrypt the SIM-based identity as part of determining whether to grant MVNO network access to the user device. Encrypted SIM-based identities enable an MVNO to rely on MVNO-controlled equipment when authenticating user devices to access MVNO network without the additional message overhead accumulated when an MNO mobile core is required to determine whether to grant access to user devices.
