Method for loading subscription data from server of mobile radio network to subscriber identity module of mobile station, involves loading subscription data from server to subscriber identity module-card over runtime environment of terminal

摘要

The method involves loading subscription data from a server (TSM) to a subscriber identity module-card (SE) over secured runtime environment (TEE) of a mobile terminal (ME) e.g. mobile phone. A cryptographically secured transmission channel (C1) is operated by the server, where the transmission channel comprises an Internet connection. The channel is produced by a trusted service manager of a mobile radio-network operator. Another cryptographically secured transmission channel (C2) is arranged between the secured runtime environment and the subscriber identity module-card.
