Embodiment Construction
[0040] figure 1 It is a flow chart of the method for realizing machine-card binding in the mobile network provided by the present invention.
[0041] like figure 1 As shown, the method includes:
[0042] Step 101, the smart card in the mobile terminal performs authentication with the network side, and if the authentication is passed, the communication key Kc information is stored in the smart card and the network side.
[0043] Step 102, the mobile terminal acquires the IMSI information and Kc information of the smart card in the mobile terminal.
[0044] Step 103, the mobile terminal determines whether step 102 is the first time that the mobile terminal acquires the IMSI information and Kc information, and if so, executes step 104, otherwise, executes step 105.
[0045] Step 104 , the mobile terminal stores the IMSI information and Kc information acquired for the first time, and proceeds to step 108 .
[0046] Step 105 , the mobile terminal compares the IMSI information a...

The invention provides a method, a system and a device for binding a mobile terminal and a smart card in a mobile network. The method comprises the following steps: when the smart card in a mobile terminal passes authentication at the network side, the information of a communication secret key Kc is stored in the smart card and the network side; the mobile terminal acquires the IMSI (international mobile subscriber identity) information and Kc information of the smart card in the mobile terminal, and compares the acquired IMSI information with the stored IMSI information; when the information is accordant, the Kc information stored in the mobile terminal is updated, otherwise, whether to update the IMSI information and the Kc information stored in the mobile terminal is determined according to user permission; and the mobile terminal communicates with the network side through the stored IMSI information and the Kc information. By virtue of the invention, the matching flexibility between the mobile terminal and the smart card can be improved.
Description
technical field [0001] The present invention relates to the technical field of mobile communication, and in particular, to a method, system and device for realizing machine-card binding in a mobile network. Background technique [0002] Binding the mobile terminal with the smart card therein is referred to as machine-card binding. Through machine-card binding, the terminal can not work normally after replacing the smart card. [0003] For example, if a mobile terminal with machine-card binding function is lost or stolen, inserting a new SIM card will not work normally, thus protecting the rights and interests of the mobile terminal holder to a certain extent and reducing the motive for theft. [0004] The existing machine-card binding technical solutions include: [0005] Preset matching symmetric keys in the mobile terminal and the smart card: For example, the same key is preset in the mobile terminal and the SIM card. During the power-on process or the use process, the m...
