Problems solved by technology

[0007] At the same time, many enterprise-level users have put forward the demand for batch interlocking between terminal mobile phones and SIM cards, that is, it is required that a batch of SIM cards can be used normally on any of a batch of mobile terminals, and this batch of mobile terminals can also use this batch of SIM cards. Any one of the SIM cards in the card, but if the batch of mobile terminals and the batch of SIM cards do not cooperate with each other, neither of them can work normally

Embodiment Construction

[0031] The invention provides a method for batch interlocking SIM cards or USIM cards and terminals by using the EF-ICCID file and PIN code function of the SIM card. The terminal may be a mobile phone, a data card, a netbook, and the like. In the following embodiments, a mobile phone is taken as an example for illustration.

[0032] The initial PIN code of the SIM card is obtained from the EF-ICCID file according to a certain encryption algorithm, and the PIN code function is enabled when the SIM card leaves the factory. Since the EF-ICCID file is the The contents of the EF-ICCID files of each SIM card are different, so the PIN code values ​​obtained after passing through the encryption algorithm are also different. In this embodiment, when producing a batch of SIM cards, the SIM card provider writes a value to the unique identifier EF-ICCID file of each SIM card in the batch of SIM cards and calculates the value used when initializing the SIM card according to an encryption ...

Abstract

The invention relates to a method for batch interlocking of terminals and cards and a terminal thereof. The terminal comprises a read module, an information generation module, and a detection judgment module, and has the function of automatically interlocking the terminal and the card. The method comprises the step of: by setting the same cryptographic algorithm for the terminals and the cards, realizing the interlocking of a batch of terminals and a batch cards which are matched with the terminals, wherein the batch of terminals and the batch of cards can be freely matched to use. When any side goes wrong, the failure can be repaired by replacing the terminal or card in the same batch; and simultaneously, for enterprise-level users, the users can effectively control the terminals and thecards, namely the cards of the enterprises can only be used in the mobile phones customized for the enterprises, the terminals of the enterprises can only use the customized cards either, and an operator can realize the customization aiming at the enterprise-level users.

Description

technical field [0001] The present invention relates to the technical field of mobile wireless communication systems, and more specifically, to a method and terminal for machine-card batch interlocking. Background technique [0002] Subscriber Identity Module (Subscriber Identity Model, SIM card) is a smart IC card with a microprocessor packaged in plastic. It is an indispensable and important part of the communication network system and is the registration certificate for users to enter the network. In the SIM card, it contains user identification information, supplementary service information, short message, mobility information and radio resource information, etc. In the network system, through the clear definition of the physical interface and logical interface of the SIM card, the connection and information exchange with the mobile terminal are completed, and at the same time, the user information is stored, the authentication algorithm is executed, and the encryption k...
