Apparatus and method for realizing self-adapatable function in telecommunication protocol

Abstract

The invention is used for making the smart card operation system capable of automatically selecting a corresponding communication protocol according to the communication protocol type of the terminal. The apparatus thereof comprises: a communication protocol setting module, a communication protocol detecting module, a communication protocol selecting module. The method thereof comprises: setting up a communication protocol for the smart card operation system; deciding if the communication protocol type of the smart card operation system is accordance with the communication protocol type of terminal; if not, selecting a communication protocol for the smart card operation system.

Description

technical field [0001] The invention relates to communication technology, in particular to a device and method for realizing self-adaptive functions in communication protocols. Background technique [0002] Communication protocol is an essential and very important part of modern communication system. The communication protocol is called the software of the communication system, which completes the transmission of communication information together with the hardware (various communication devices). [0003] Two contactless communication protocols are defined in the ISO14443 standard: Type A and Type B. Among them, Type A was first developed and used by semiconductor companies such as Philips. Its main features are simple and concise design, short development cycle of application projects, and can be applied to many occasions at the same time. Type B is an open contactless smart card standard, and all read and write operations can be defined by specific application system de...

Problems solved by technology

[0006] The disadvantage of manually selecting the non-contact communication protocol of the smart card operating system is that when the user uses the smart card, he must know the type of communication protocol used by the terminal in advance, and then he can manually adjust the current communication protocol type of the smart card operating system accordingly, so that the smart card The current communication protocol type of the operating system is consistent with the communication protocol type used by the terminal

But this brings a lot of inconvenience to the user, and the user does not know which communication protocol should be used in many cases, which makes the user unable to use the smart card to complete the corresponding function

Especially when multiple communication protocols exist, such as Type C / Type D / Type E / Type F / Type G and other 5 types of communication protocols, it is even more difficult to ensure the smooth progress of communication
