Abstract

A METHOD OF USING A CIPHERING KEY IN A MOBILE STATION (40) FROM A FIRST BASE STATION (12) IN A FIRST CELLULAR COMMUNICATIONS SYSTEM CONTROLLED BY A FIRST MOBILE SWITCHING CONTROL STATION TO A SECOND BASE STATION (14) IN A SECOND, DIFFERENT CELLULAR SYSTEM CONTROLLED BY A SECOND MOBILE SWITCHING CONTROL STATION IS DESCRIBED.THE METHOD COMPRISES GENERATING FOR THE MOBILE STATION (40) A CIPHER KEY FOR USE BY THE MOBILE STATION (40) DURING COMMUNICATION IN THE SECOND CELLULAR COMMUNICATIONS SYSTEM.THE CIPHER KEY IS GENERATED BY THE MOBILE STATION (40) FROM A PRIVATE KEY ASSIGNED TO THE MOBILE STATION (40) FOR THE SECOND CELLULAR COMMUNICATIONS SYSTEM AND FROM A RANDOM NUMBER GENERATED BY THE SECOND CELLULAR COMMUNICATIONS SYSTEM. THE CIPHER KEY IS THEN COMMUNICATED TO THE FIRST MOBILE SYSTEM AND A PRIVATE LONG CODE IS GENERATED FOR USE BY THE MOBILE STATION (40) DURING COMMUNICATION IN THE FIRST CELLULAR COMMUNICATIONS SYSTEM.(FIG 4)
