Claims (12)

1. A telecommunication system comprising at least one main station (1) and a plurality of subscriber devices (6, 7), wherein the main or each main station is designed to transmit messages to at least one subscriber device and each subscriber device (6, 7 ) has many permanent memory cells (22), and a means of responding to the detection of such a message by storing a message in the selected permanent memory cell, which cannot be overwritten from this subscriber unit (6, 7), but to which if It can be accessed from a subscriber unit, characterized in that each subscriber unit (6, 7) contains means (27, 28) that respond to a command transmitted from the main station (1) by selectively turning on or blocking permanent memory cells for overwriting or reading from the main, or from each main station (1), or from a subscriber unit (6, 7).  2. The system according to claim 1, characterized in that at least one subscriber device (6, 7) comprises a transceiver (6) and a card (7) with an integrated circuit or another module having permanent memory cells (22), and means that responds to the detection of a message by the transceiver by sending it to the selected permanent memory cell, and this module is removably connected to the transceiver.  3. The system according to claim 1 or 2, characterized in that each memory cell (22) is associated with a simple code and the subscriber unit (6, 7) contains means that respond to the input of each code into the device by searching for data in the associated memory cell.  4. The system according to any one of paragraphs. 1 to 3, characterized in that the main or each main station (1) is designed to transmit a request for information stored in a permanent memory cell (24) in the selected subscriber device (6, 7), and each subscriber device contains means that respond on such a request for the search and transmission of information.  5. The system according to claim 4, characterized in that the means responding to this request is only activated after entering a personal identification number into the subscriber unit (6, 7).  6. The system according to any one of paragraphs. 1 - 5, characterized in that the subscriber device (6, 7) contains many additional cells of permanent memory, which can be overwritten from the subscriber device (6, 7).  7. The system according to any one of paragraphs. 1 - 6, characterized in that each subscriber unit (6, 7) contains means responsive to a command transmitted from the main or each main station (1) by running a program stored in a permanent memory cell or an additional permanent memory cell in a subscriber device (6, 7).  8. The system according to p. 8, if it depends on p. 5, characterized in that the message or each message, a request for information and a command are transmitted in a special format and the subscriber unit (6, 7) contains means (16) to recognize this special format.  9. The system according to any one of paragraphs. 3-8, in the case of its dependence on p. 2, characterized in that the module (7) contains a means that responds to the detection of a message by storing the message in the selected memory cell, and / or means that responds to the input of a simple short code by data search in an associated memory cell, and / or a means of responding to a request for information presentation by searching and transmitting this information, and / or a plurality of additional permanent memory cells that can be overwritten by a subscriber, and / or means for selectively switching on or and blocking additional cells of read-only memory for overwriting or reading, and / or means for running a program, and / or means for recognizing a special format.  10. A module (7) for controlling a subscriber device in a telecommunication system, removably connected to a transceiver (6) of a subscriber device and containing a plurality of read-only memory cells (22, 24) and means for responding to the detection of a message remotely transmitted to it by storing this message in a selected permanent memory cell, characterized in that it contains means (27, 28) that responds to commands transmitted remotely by opening or blocking access to any or all of the permanent memory cells For overwriting or reading by the subscriber unit or main station.  11. The module (7) according to claim 10, characterized in that it contains a structure (21) consisting of directories in which files can be stored.  12. The module (7) according to claim 10 or 11, characterized in that it is made in the form of a card with an integrated circuit.
