Terminal and authorization card for a subscriber, telecommunications network, and method for modifying a service profile assigned to the subscriber

摘要

To be able to modify the service profile of a subscriber of a telecommunications network, a terminal (MS) is proposed having input and output means (KBD; LCD) as well as a processor (&mgr;P) connected thereto which accesses a data memory (MEM) which the subscriber can remove from the terminal and carry with him or her. The data memory is an erasable memory (MEM) which holds data for the service profile assigned to the subscriber. The processor (&mgr;P) controls the input and output means (KBD; LCD) so that the subscriber can have the service profile data output at the terminal and modify them. This reduces the signaling load on the link between the terminal and the telecommunications network. Preferred applications of the invention are in telecommunications networks using authorization cards (SIM), particularly mobile radio networks (MRN).
