Abstract
A mobile radio network comprising a plurality of mobile radio stations and at least one mobile radio exchange for controlling communication within a mobile radio network, the subscribers being identified with respect to the mobile radio network by means of a chip card (Subscriber Identity Module--SIM) which is inserted into the mobile radio station. The mobile radio network incorporates a short message service which transmits to the subscriber chip cards (SIM cards) data in a predetermined short message format containing a standardized header. The short messages can be of two types: (a) a conventional short message whose data only contain information for the subscriber which is temporarily stored in the subscriber chip card (SIM card) and can be displayed on a mobile radio station display; and (b) a reconfiguration short message which can reconfigure the subscriber chip card (SIM card) in given data fields. In order to recognize and differentiate between a reconfiguration short message and a conventional short message, the subscriber chip card contains a recognition and differentiation filter suited to the program, for evaluating the header of the short message.
