METHOD FOR DETECTING IMPOSTURE USE OF WIRELESS COMMUNICATION FOR USER ASSIST

摘要

PROBLEM TO BE SOLVED: To detect the imposture use in a wireless communication system. SOLUTION: In the case that a 1st wireless communication system is accessed by using a subscriber account, the system stores data to recognize a 1st access to a database 126. In the case that a 2nd access is made to the system by using the same subscriber account, the system transfers at least part of the storage data to recognize the 1st access to a wireless device 116 used for the 2nd access. The user of the device 116 reviews the data to decide whether or not the 1st access is valid and gives an instruction as to whether or not the 1st access is based on imposture access. In the case that the 1st access is suspicious of the imposture use according to the reply, the wireless communication service provider takes a proper action.
