Abstract
Methods and devices in a mobile communications system for over the air management of mobile stations contain a secure identification element such as a subscriber identity module. A standard challenge-response authentication procedure is implemented in a mobile communications system not for its intended authentication purpose, but for providing a mobile station with subscription data. The standard challenge-response authentication procedure is modified in that the challenge is used as a carrier for subscription data. The challenge containing the subscription data is provided to the mobile station in response to a request of the mobile station to be allowed access or attachment to the mobile communications system containing a special mode indicator data element, which indicates to the mobile communications system that the mobile station is requesting subscription data and suitably forwarded to a data providing unit configured to provide subscription data.
