Embodiment Construction

[0027] figure 1 It is a flow chart of an embodiment of the processing method that the present invention detects SIM card duplication, as figure 1 As shown, the method of the present embodiment includes:

[0028] Step 101. Record the information of the SIM card currently registered in the network and the corresponding terminal identification and / or location information.

[0029] Specifically, the information of the SIM card includes: IMSI, Temporary Mobile Subscriber Identity (Temporary Mobile Subscriber Identity; TMSI for short), packet domain temporary subscriber identifier (P-TMSI), and the like. It should be noted that the TMSI is temporarily assigned to the mobile terminal by a core network (Core Network; CN for short) for the purpose of protecting the IMSI, and uniquely corresponds to the IMSI. The IMSI is used when the mobile terminal initiates network registration after booting up. After the registration is successful, the CN assigns the TMSI to the mobile terminal. A...

Abstract

The invention provides a processing method and processing equipment for detecting SIM (Subscriber Identity Module) card replication. The processing method comprises the steps of: recording SIM card information recorded in a network currently and corresponding terminal identities; and if the SIM card information corresponds to at least two terminal identities and / or position information within first preset time, carrying the SIM card information in a notification message to be sent to an operation and maintenance center so that the operation and maintenance center can make a judgment on whether the SIM card information is replicated illegally.

Description

technical field [0001] The invention relates to communication technology, in particular to a processing method and equipment for detecting duplication of SIM cards. Background technique [0002] Subscriber Identity Module (SIM for short), also known as smart card or subscriber identity card, is used to insert any mobile phone that conforms to the Global System for Mobile Communications (Global System for Mobile Communications; GSM for short) specification middle. [0003] Normally, a Mobile Subscriber International ISDN / PSTN number (MSISDN for short) should only correspond to one SIM card, but there is currently a SIM card duplication technology, that is, through a special card reader , read and decrypt the data in the SIM card, so as to obtain the Key Identifier (Key Identifier; KI for short) and the International Mobile Subscriber Identification Number (International Mobile Subscriber Identification Number; IMSI for short) in the SIM card, and then use the KI and IMSI co...
