Abstract: 1. A method of transmitting a message in a mobile communication system, consisting of generation (38), by a mobile communication means (1), e.g. a radio telephone, of an electromagnetic radiation coded by this message, for example by modulation, and having predetermined values of power and frequency, characterised in the steps of generating (39), by the mobile communication means (1), a message-coded auxiliary radiation; for each mobile communication means (1) at least one mobile repeater (2) being used, which repeater receives and processes the auxiliary radiation, and also generates and transmits said message-coded electromagnetic radiation; assessing (33) quality of communication of the mobile communication means having corresponding mobile repeater (2) using the auxiliary radiation; the pre-determined value of the message-coded electromagnetic radiation generated by the mobile communication means (1) being set (38) in conformance with said communication quality assessment within the range from zero to a predetermined value. 2. The method as claimed in Claim 1, characterised in generating (39), by the mobile communication means (1), a message-coded auxiliary light or infrared radiation. 3. The method as claimed in Claim 1, characterised in generating (39), by the mobile communication means (1), a message-coded auxiliary ultrasound radiation. 4. The method as claimed in Claim 1, characterised in changing (35) power of the auxiliary radiation according to the communication quality assessment. 5. The method as claimed in Claim 1, characterised in performing (38) an audible or visual indication of an unsatisfactory assessment of the communication quality. 6. The method as claimed in Claim 1, characterised in performing (36) an audible or visual indication of a satisfactory assessment of the communication quality. 7. The method as claimed in Claim 1, characterised in predetermining (34) such values of assessment of the quality of said communication, at which values the message-coded electromagnetic radiation is emitted (39) only through the corresponding mobile repeater (2). 8. The method as claimed in Claim 1, characterised in predetermining ("No" in condition 34) such values of assessment of the quality of said communication, at which values the message-coded electromagnetic radiation is emitted (39) only by the mobile communication means (1). 9. The method as claimed in Claim 1, characterised in assessing (40) quality of message transmission in the mobile communication system, according to results of which assessment, parameters of electromagnetic radiation are changed (42, 43) by transmitting an appropriate control signal to mobile repeater (2) from the mobile communication means (1). 10. The method as claimed in Claim 9, characterised in determining (44), according to the quality assessment, the number of the mobile repeaters (2) that generate and transmit the message-coded electromagnetic radiation. 11. The method as claimed in one of Claims 1-10, characterised in indicating (32), on indicator of the mobile communication means (1), status of a power supply source of the mobile repeater (2). 12. An apparatus for transmitting a message in a mobile communication system (1), comprising one or a plurality transceivers (14) coupled to a control unit (17), parameters of at least one of which transceivers being consistent with parameters of at least one mobile repeater (2) that comprises a transceiver (22) connected to a control unit (25), and a power supply source (27), characterised in further comprising a unit (19) for inputting an auxiliary radiation code, which unit is coupled to the control unit (17). 13. The apparatus as claimed in Claim 12, characterised in that one of transceivers (15) is implemented in the form of a light, infrared or ultrasound radiation transceiver. 14. The apparatus as claimed in Claim 12, characterised in that the unit (19) for inputting the auxiliary radiation code consists of one or a plurality of switches. 15. The apparatus as claimed in Claim 12, characterised in that the mobile repeater (2) comprises means (28), (29), connected to the power supply source, for activation of the mobile repeater (2) from the stand-by mode. 16. The apparatus as claimed in Claim 12, characterised in that the mobile repeater (2) comprises means (26) for establishing a unique code, connected to the control unit (25). 17. The apparatus as claimed in Claim 16, characterised in that the means (26) for establishing a unique code consists of one or a plurality of switches. 18. The apparatus as claimed in Claim 12, characterised in that the mobile repeater (2) is positioned inside a vehicle, a car, for example. 19. The apparatus as claimed in Claim 12, characterised in that the mobile repeater (2) is positioned in an object carried by a subscriber, e.g. portfolio or attache case. 20. The apparatus as claimed in Claim 19, characterised in that on the exterior side of the object carried by a subscriber positioned is an indicator of operation modes of the mobile repeater (2). 21. The apparatus as claimed in any one of Claims 12-20, characterised in that the mobile repeater (2) comprises a plurality of the transceivers (22) coupled to the control unit (25).
