Embodiment Construction

[0129] The wireless interface between the communication terminal interface device and the smart SIM card holder device can use different technical solutions, such as short-distance wireless communication technology Bluetooth, wireless local area network, etc., and the specific wireless transmission solutions of different equipment providers are also different. , so the SIM card wireless data packet transmission of the present invention can have different specific implementations. The technical implementation of the present invention will be specifically described below by taking the Bluetooth System on Chip (SoC, Systemonchip) chip nRF51822 of Nordic Corporation of Norway as an example.

[0130] Chip nRF51822 supports multi-protocol 2.4G wireless communication, including proprietary wireless transmission protocol and standard low-power Bluetooth 4.0 protocol. Users can also use its application programming interface to implement their own application communication protocols. Su...

Abstract

The invention belongs to the field of mobile communication terminals. The invention discloses a format and method suitable for wireless data transmission between a mobile communication terminal and a SIM card so that command session data is transparently and effectively transmitted through wireless transmission interfaces between the mobile communication terminal and the SIM card. Through wireless transmission frame package of a command session data package, error detection of received data, automatically repeated transmission of received error data packages, random frequency hopping on wireless transmission signal channel frequency, using conflict detection of signal channels, and data buffering of command session interactions, etc., highly efficient wireless data transmission is realized between a cell phone and a SIM card; the method has no influence on present data interchange between a cell phone and a SIM card. According to the invention, a SIM card application function menu is established in the cell phone through a SIM card application toolbox so that the cell phone is operated actively by a user to access a network.

Description

technical field [0001] The invention belongs to the field of mobile communication terminals. Specifically, the present invention relates to a format and method suitable for wireless data transmission between a mobile communication terminal and a SIM card, so that the command session data can be transmitted transparently and effectively through the wireless transmission interface between the mobile communication terminal and the SIM card . Background technique [0002] Mobile phones, especially smart phones, are becoming more and more important in people's lives. Smart phones have become an essential device in people's daily life. People complete various mobile applications through the smart phones they carry with them. In addition to basic voice calls and text messages, traditional Internet applications such as watching videos, viewing photos, browsing the web, etc. can also be used on smartphones. Especially for various application functions, there are various independent...
