Abstract
A method for detecting fraudulent use of a communications system detects and prevents fraud by assigning codes or randomly generated codes for communication access between a subscriber station and a fixed end and updating the codes upon the occurrence of one or more key events associated with subscriber activity in the communications system. The method permits detection and monitoring of fraudulent activity by permitting a legitimate subscriber station and an illegitimate subscriber station to have two different codes or dynamic codes after the legitimate subscriber station's identity has been misappropriated.
