Abstract:
1. A method for re-configuring a communications device in which profile data is maintained for access to a communications service platform, wherein profile data relating to the communications device is stored on an authentication platform, and the profile is also stored in the communications device, the method comprising: if the communications device detects that the profile data is no longer stored in the communications device, the communications device generating a request for re-authentication, and transmitting the request to a reactivation server together with the communications device identity, on receipt of the request, the reactivation server retrieving the stored profile data associated with the communications device identity from the authentication platform and returning it to the communications device, the communications device storing the retrieved profile data; wherein the profile data is initially generated by interaction of the communications device with the authentication platform, such that the authentication platform generates a profile associated with the communications device identity, for storage by the authentication platform, such that the data can subsequently retrieved by the communications device; and wherein the profile data is initially generated by a first mode of communications in which a calling line identity apparent to the authentication platform is associated with a device identity, and the calling line identity is stored by the authentication platform and the device as part of the profile data for use in subsequent interactions between the communications device and the authentication platform over a second mode of communications in which the calling line identity is not apparent to the authentication platform except as part of the profile data delivered to the authentication platform.
