Abstract

The invention discloses a communication negotiation method of a mobile terminal and a smart card and a mobile terminal, wherein the method comprises: the mobile terminal selects a supply voltage of the smart card, allocates parameters for the communication of the mobile terminal and the smart card by activating the smart card and communicates with the smart card. The invention avoids the low communication speed problem between the mobile terminal and the smart card in relative technologies, effectively improves the mobile terminal performance, the processing speed and the user experience by defining a voltage selection and interface activation.

Description

technical field [0001] The present invention relates to the communication field, and in particular, relates to a communication negotiation method between a mobile terminal and a smart card and the mobile terminal. Background technique [0002] Since the early 1990s, smart cards have been successfully applied to Global System for Mobile Communication (Globle System for Mobile communication, GSM for short) terminals in Germany. At present, smart cards have been widely used in various mobile communication networks, for example, User Identification Module (UIM) cards used in Code Division Multiple Access (CDMA) terminal equipment, USIM cards used in 3G terminal equipment, etc. [0003] Usually, the smart card (also called Subscriber Identity Module, SIM for short) loaded in the mobile phone terminal is mainly used to realize identification and authentication of user identity, voice communication support, short message service, and other various functions. A value-added service...
