Abstract: A method of transferring information between a subscriber identification model and a mobile terminal constituting a station of a radiocommunication system in which at least some of the information transferred between said module and said terminal is protected by encryption. The subscriber identification module and the mobile terminal include encryption means using a key defined at least in part by periodically-varying data specific to the system.

Abstract: A method of parameterizing the display on display means associated with a piece of radiocommunications mobile equipment co-operating with a subscriber identity module, the method having the following steps in order: said subscriber identity module sends a set of commands to said mobile equipment, said commands enabling the display on said display means to be parameterized; and said commands are executed by said mobile equipment on said display means.

Abstract: A man-machine interface device for a telephone terminal for selecting options offered to the user when using services offering such options indicates to the terminal the various options that can be selected and determines, in a manner specific to each terminal, the mode of presentation of the options to the user for the purpose of making the selection.

Abstract: The invention relates to a radiotelecommunications system having a mobile terminal equipped with a subscriber identity module and designed to operate in a cellular network having a plurality of cells. The system has a private base station independent from the cellular network and connected to a wired telecommunications network.

Abstract: A communication system for organizations whose communications are assured via an international private telecommunication network and at least one other network enables a user of an accredited mobile radio terminal to pre-empt the setting up of a call via the private network from a node of the network to which it has access from a base station of a radio network. Each mobile radio terminal of the system can combine a code of the country in which it is located received from a base station with a node identifying indication that it stores and for sending dialling signals including an identification code of a node and a terminal number. The nodes of the private network enable a call to be set up to a terminal from the number of that terminal reaching the node with an identification code of that node.
