Embodiment Construction

[0033] The solution of the embodiment of the present invention is mainly: when the terminal reads the basic class file in the card, according to the validity of the initial value of each parameter in the parameter list of the basic class file, the value of the indication bit of the corresponding parameter is modified, and the modified The value of the indication bit of the corresponding parameter is stored in the card, so that the card conforms to the standard protocol, so as to improve the compatibility of the terminal to the card.

[0034] The terminal in the present invention may be a mobile terminal such as a mobile phone, and the following embodiments take the compatibility between the mobile phone and the SIM card as an example for description, but it is not limited to the above situation. In the embodiment of the present invention, the mobile phone can be compatible with the SIM card regardless of whether it conforms to the protocol specification or not, and can modify t...

Abstract

The invention relates to a method for improving the card compatibility of a terminal and the terminal. The method comprises the following steps of: reading a basic file from a card by using the terminal; acquiring initial values of each parameter in a parameter list of the basic file, and modifying values of indicating bits corresponding to the parameters according to the validity of the initial values; and storing the modified values of the indicating bits corresponding to the parameters into the card. By the method and the terminal, when the terminal reads the basic file from the card, the values of the indicating bits corresponding to the parameters are modified according to the validity of the initial values of each parameter in the parameter list of the basic file, and the modified values of the indicating bits corresponding to the parameters are stored in the card, so that the card is consistent with the specifications of a standard protocol, the card compatibility of the terminal is improved, and project development time is shortened at the same time.

Description

technical field [0001] The present invention relates to the field of communication technologies, and in particular, to a method and a terminal for improving the compatibility of a terminal to a card. Background technique [0002] Existing mobile terminals such as cell phones are equipped with a SIM card (Subscriber Identification Module, subscriber identification card). Since there are many SIM card manufacturers and they are uneven, the understanding of the protocol is inconsistent among SIM card manufacturers, which makes the implementation standards and file parameter settings of each SIM card inconsistent, and some SIM cards do not even conform to the standard protocol. This poses a challenge to the matching and compatibility of mobile phones. The mobile phone must show good compatibility with different SIM cards. [0003] Existing mobile phones have poor compatibility with their installed SIM cards, especially SIM cards that do not conform to standard protocols, and c...
