Embodiment Construction

[0058] The specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings, but it should be understood that the protection scope of the present invention is not limited by the specific embodiments.

[0059] The basic requirement of the present invention is that the operator needs to set up a corresponding functional module in the core network part (or through the operator's server), and the functional module can be named as the SIM card security management module. The automatically transmitted SIM card information is used to determine whether to activate certain functions of the SIM card. Because the user's mobile phone is usually protected by multiple passwords, the current unauthorized users who illegally use other users' financial accounts (hereinafter referred to as "unauthorized users") basically need to connect the SIM card in the stolen mobile phone to other mobile phones or card readers. Complete the SIM card...

Abstract

The invention discloses a SIM card anti-theft method and system, comprising: a first mobile terminal is powered on and reads SIM card information in the first mobile terminal; the first mobile terminal establishes a communication connection with a relay mobile terminal; After the relay mobile terminal establishes the communication connection, the first mobile terminal requests the relay mobile terminal for transmission resources; after requesting the relay mobile terminal for transmission resources, the first mobile terminal receives the resources allocated by the relay mobile terminal; After the resources are allocated by the relay mobile terminal, the first mobile terminal sends one or more types of information to the relay mobile terminal on the allocated resources based at least in part on different priorities of the type A information, type B information, and type C information information; after receiving one or more types of information among type A information, type B information and type C information, the relay mobile terminal transmits one or more types of information from type A information, type B information and type C information via the base station. Class information is sent to the core network.

Description

technical field [0001] The invention relates to the technical field of SIM card security, in particular to a method and a security system for preventing theft of a SIM card. Background technique [0002] Under the current conditions, the loss of a mobile phone is the most likely to cause a great loss to the user's financial account, and the loss of the value of the mobile phone itself rarely has a significant impact on the user. At present, major banks or enterprises or institutions with financial attributes generally use SMS verification codes to verify financial operations such as transfers, loans, and "white notes". In this case, unauthorized users must be able to use a functioning SIM card before Able to complete SMS verification operation. With the help of the verification mechanism, a related method can be designed to ensure the security of the SIM card. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to provide a method and system for pre...
