Abstract

The system is composed of handset, SIM card, network and international mobile equipment identification (IMEI) server. Using the system, handset user logs on network and sends IMEI number automatically. IMEI server receives IMEI code sent by SIM card, and binds IMEI code with user's IMSI code and number of the handset, building corresponding user's index database. Using IMEI protection cipher carries out authentication of handset user's id. Temporary index for illegal user is built. If illegal user logs on network by using stealing handset, id of illegal user can be known from IMEI.
