    Patent number: 6164547
    Abstract: A method for checking the compatibility of a mobile station (201) and a functional unit (207); a mobile station (201) and a functional unit (207). A reference code (104, 105) is calculated in the mobile station (201) and the functional unit (207) by using algorithms which use initial numbers given by the mobile station (201), and the results are compared in the mobile station (108, 201). On the basis of the comparison it is concluded, whether the functional unit (207) is compatible with the mobile station (201), and whether it is to be activated (110, 112). In order to carry out the check measures, a check message including preferably name of the mobile station manufacturer/agent (302), IMEI code (303), product code (304), version data (305, 306), and random number (307), is transmitted to the functional unit (207).
