Abstract

The present invention provides a method and device for writing data into an intelligent card, relating to the technical field of data processing of intelligent cards. The method comprises the following steps: acquiring downlink data to be written; grouping and packeting commands according to the downlink data to be written to generate command data packets, the command data packets including non-ordinary telephone directory identifiers and instruction types; writing the command data packets into a telephone directory of the intelligent card via an intelligent card telephone directory function channel. According to the present invention, data may be written into the telephone directory of the intelligent card via the intelligent card telephone directory function channel, so that the device for writing data into the intelligent card may write data into corresponding positions of the intelligent card according to the instruction types. According to the present invention, no bottom layer code modification is needed on a terminal side, a simple and convenient data transmission mode can be realized, and problems of complexity, unstable data transmission and the like of a conventional mode for the terminal to write data into the intelligent card can be prevented.

Description

technical field [0001] The invention relates to the technical field of smart card data processing, in particular to a method and device for writing data into a smart card. Background technique [0002] User identification card, also known as smart card, is a necessary setting for smart terminals such as mobile phones to authenticate customers. Smart cards can store digital mobile phone customer information, encrypted keys, and user phonebooks on computer chips, which can be used to identify customer identities on the GSM network and encrypt voice information during customer calls. [0003] Currently, in order to better manage and control the smart card, a terminal with a smart card can generally write data into the smart card. Currently, there are OTA and Open Mobile API methods for writing data to smart cards. Among them, the OTA method is Over-The-Air Technology (Over-The-Air Technology) technology, which writes data into the smart card through the air channel. However,...
