Abstract
A method for automatically updating shared secret data stored in a mobile terminal comprises initiating a shared secret data update procedure upon receipt of an access attempt by a mobile terminal in a mobile switching center. The shared secret data update procedure is initiated in accordance with a schedule determined by the wireless service provider. Reporting of the outcome of the shared secret data update attempt is issued by the mobile switching center to wireless service provider personnel for telecommunications system maintenance purposes. Advantageously, shared secret data updates occur automatically without intervention by wireless service provider personnel.
