Abstract:

Authenticating a mobile user device with a mobile network operator in advance of an MNO authentication request from the mobile user device can be done by a satellite network sending an authentication request to the MNO system, obtaining a set of authentication vectors related to the mobile user device, storing them into a proxy home location register, receiving the MNO authentication request from the mobile user device, generating an authentication request response based on the authentication vectors, sending the authentication request response to the mobile user device, receiving an authentication response including a received signed response, comparing the received signed response with the stored signed response, and if the received signed response and stored signed response match, deem that to be a successful authentication, add an MNO location update message to a request queue and forward the MNO location update message to the MNO system over the channel when available.
