Terminal smart card implementing method and chip

Abstract

The invention discloses a terminal smart card implementing method and a chip. The method comprises: transmitting a requesting message of interaction with a peripheral of a terminal to a communication chip in the terminal, wherein the parameters of the requesting message carry content information of interaction with the peripheral of the terminal; receiving an interaction response message, transmitted from the communication chip, of the peripheral of the terminal, wherein the response message carries result information of interaction with the peripheral of the terminal; transmitting a corresponding service function request to a mobile communication network by using the communication chip according to the result information of the interaction. A terminal smart card communicates with the communication chip with a message interface or API calling interface. The request message of interaction with the peripheral of the terminal and the response message of interaction with the peripheral of the terminal are transmitted and received by the communication chip. According to the result information of interaction, the corresponding service function request is transmitted to the mobile communication network by the communication chip. Therefore, a problem of low communication rate between the terminal smart card and the terminal is removed.

Description

technical field [0001] The present invention relates to the technical field of smart cards in the communication field, in particular to a method for realizing a terminal smart card and a chip. Background technique [0002] In existing IoT applications, M2M (Machine To Machine, machine-to-machine) terminals directly use the traditional Subscriber Identity Module (SIM card hereinafter) or User Identity Module (UIM hereinafter). Card) for communication, such as electric remote meter reading terminals, vehicle-mounted terminals in the transportation industry, etc.; at the same time, most of the SIM cards / UIM cards in the above-mentioned terminals only need to activate the GPRS / CDMA data communication function to realize the information interaction between the terminal and the background. There is no need to open functions such as voice and SMS. [0003] The existing M2M terminal uses the SIM card / UIM card to have the following technical problems: [0004] (1) The SIM card / UIM ...

AI Technical Summary

Problems solved by technology

[0004] (1) The SIM card / UIM card is inserted into the dedicated card slot inside the terminal, and it is connected to the M2M terminal in the form of contact, which has low reliability and is not suitable for working in harsh environments; and the M2M terminal is connected to the SIM card / UIM cards communicate through existing interface standards, and there is a bottleneck in the communication rate

[0005] (2) After the M2M terminal has been working in a harsh environment for a long time, the SIM card / UIM card with hardware entities is easily damaged or unreliable contact occurs, resulting in the failure of normal communication between the M2M terminal and the network; and when the M2M terminal After a communication failure, it is difficult to locate the problem, because the failure of the M2M terminal itself, the communication network problem, the poor contact of the SIM card / UIM card, the damage of the SIM card / UIM card itself, etc. may cause the communication failure of the M2M terminal
