Problems solved by technology

The first method cannot accurately distinguish multiple types of SIM cards of the same operator, because the MCC and MNC of these SIM cards are the same
The disadvantage of the second method is that the number of IMSI numbers stored in the mobile phone is limited after all, so the number of locked SIM cards is limited

Embodiment Construction

[0016] The invention provides a method and a terminal for binding a SIM card by using the STK function of the SIM card.

[0017] The principle of the technical solution of the present invention is: the terminal sends a terminal profile command when the SIM card is initialized to inform the related items of the STK supported by the SIM card, and the SIM card provides it to the operator related to the terminal SIM card by actively reporting a proactivecommand report or providing a menu item Information, the terminal judges whether the SIM card operator information of the STK function matches the SIM card operator information stored in the terminal, and if it matches, the user is allowed to use the terminal normally; if it does not match or the STK function does not provide SIM card-related operator information , the terminal does not allow the user to use the terminal normally. In this way, the purpose of terminal card locking is realized by using the STK function of the SIM car...

Abstract

The invention relates to a terminal and a method for binding an SIM card. In the method, the terminal assigns a terminal profile command to inform a related SIM card-supported item of an STK when the SIM card is initialized, the SIM card provides operator information related to the SIM card to the terminal by actively reporting a proactive command report or providing a menu item, and the terminal judges whether the SIM card operator information in the STK function is matched with the SIM card operator information stored in the terminal; if the two are matched with each other, a user is allowed to normally use the terminal; and if the two are not matched or the STK function does not provide the operator information related to the SIM card, the user is not allowed to normally use the terminal. Thus, the purpose of terminal card lock is achieved by using the STK function of the SIM card. The invention can realize the separate binding of different types of SIM cards under the same operator, and the quantity of the locked SIM cards is not limited.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, and more specifically, to a terminal and method for binding a SIM card. Background technique [0002] With the development and popularization of 3G technology, the competition among operators is intensifying. The sales of mobile terminal equipment are increasingly being customized by operators, and the card lock function is one of the most important customization methods. Only one or several SIM cards customized by the operator can be used on the mobile terminal with the card locking function, while other SIM cards cannot be used normally when inserted into the mobile terminal of this type. The card lock function can ensure that the user only uses the SIM card of a specific operator to protect the interests of the operator. Most of the current card locking technologies use the MCC (country code) and MNC (area code) of the International Mobile Subscriber Identification Num...
