Abstract

The invention discloses a method for achieving an SIM (subscriber identity module) card function on a terminal, the terminal and a UICC (universal integrated circuit card). The method comprises the steps of: downloading information for achieving the SIM card function; writing the information for achieving the SIM card function into a preserved storage space of the terminal; and after the SIM card is activated, carrying out authentication on an access identity of a terminal user through the information for achieving the SIM card function. According to the method, the information for achieving the SIM card function is downloaded to the terminal, and the SIM card function is achieved in a software mode. Therefore, an SIM card chip does not need to be frequently exchanged when the user roams between different regions; the SIM card function can be achieved in a software manner according to the embodiment of the invention. Therefore, convenience is brought to the user, and the user experience is improved.

Description

technical field [0001] The present invention relates to the field of communication technology, and in particular to a method for realizing the function of a Subscriber Identity Module (SIM) card on a terminal, a terminal and a Universal Integrated Circuit (UICC). Background technique [0002] The subscriber identity module (Subscriber Identity Module, SIM) card used in the existing global system of mobile communication (Global System of Mobile Communication, GSM) is also called a smart card, a subscriber identity card, and the like. A SIM card is usually a chip that can be installed in a mobile terminal, and is used to store user information, encryption keys, and user phonebooks of the mobile terminal, as well as to provide the GSM network for authentication of network users, and for users to communicate with each other when they talk. Voice information is encrypted, etc. [0003] The SIM card in the prior art is usually a chip with a microprocessor and has a hardware struc...
