A control method, device and system for a user identification card

Abstract

The invention discloses a user identification card control method, device and system, which are used to resist the problem of high arrears caused by illegal copying of the user identification card. The control method of the user identification card includes: when determining that there is a duplicating card in the user identification card of the arrears shutdown, extracting the user identification of the user identification card and the equipment addresses of each VLR logged in; , determine the HLR to which the user identification card belongs; notify the HLR to record the equipment address of each VLR for the user identification card in the HLR, and notify the HLR to record the equipment address of the current VLR after the completion of the equipment address recording. The user identification card executes the arrears shutdown operation.

Description

technical field [0001] The invention relates to the field of mobile communication, in particular to a method, device and system for controlling a user identification card. Background technique [0002] Subscriber identification cards adopted in mobile communication systems of existing various network standards, such as SIM (Subscriber Identity Module, Subscriber Identity Module) card, CDMA (Code The UIM (User Identity Module, User Identification Module) card used in the Division Multiple Access (Code Division Multiple Access) system, and the USIM (Universal Subscriber Identity Module, Universal Subscriber Identity Module) used in the UMTS (Universal Mobile Telecommunications System, Universal Mobile Communications System) Identification module) cards, etc., all belong to the category of smart cards. In the mobile communication system, the mobile terminal (usually a mobile phone) is separated from the user identification card. The user identification card can uniquely identi...

Problems solved by technology

According to the GSM protocol, since the SIM card logs into other VLRs, the user data related to the SIM card is recorded, and the user data includes IMSI and authentication triplet, wherein the authentication triplet refers to SRES, RAND and Kc, Although the SIM card has been shut down, billing services can still occur, such as sending short messages, calling services, etc. The SIM card with the duplicate card will be out of control, resulting in high arrears

Since there is a duplicated user ID card that can log in to multiple VLRs at the same time, and after the arrears shutdown operation is performed on the user ID card, only the user data related to the user ID card stored in one of the VLRs can be cleared. If the user data in other VLRs is not cleared, it may cause the user identification card to still be able to generate billing services. In the prior art, it can only be cleared manually, and each VLR that the user identification card logs in may be widely distributed, often Cross-provincial network, resulting in a lot of coordination work and time-consuming
