Embodiment 1

[0053] The implementation method of contactless communication in this embodiment is applied to the first terminal, such as figure 2 shown, including the following steps:

[0054] Step 201: When performing contactless communication, the baseband chip of the first terminal opens a logical channel with the user identification module card of the first terminal;

[0055] Here, in actual application, the baseband chip is triggered to open a logical channel with the subscriber identity module card by the first piece of non-contact information from the second terminal. Specifically, the first piece of contactless information may be a contactless transaction instruction from the second terminal;

[0056] Correspondingly, the baseband chip needs to perform analog-to-digital conversion on the contactless transaction instruction so as to transmit it to the SIM card, and at this time, trigger the baseband chip to open a logical channel with the SIM card.

[0057] Specifically, the contr...

Embodiment 2

[0078] In order to implement the method of the embodiment of the present invention, this embodiment provides a baseband chip, such as image 3 As shown, the baseband chip includes:

[0079] The logical channel manager 31 is configured to open a logical channel with the subscriber identity module card of the first terminal where it is located when performing contactless communication;

[0080] Analog-to-digital-to-analog converter 32, used to receive contactless information from the second terminal; perform analog-to-digital conversion on the contactless information of the second terminal, and use the logical channel manager 31 to open the logical channel Up-transmitting the contactless information after analog-to-digital conversion to the subscriber identity module card; and receiving contactless information from the subscriber identity module card on the opened logical channel through the logical channel manager 31; performing digital-to-analog conversion on the non-contact ...

Abstract

The invention discloses a non-contact communication realization method. The method comprises the steps that when non-contact communication is carried out, a baseband chip of a first terminal opens a logic channel of a user identification module card of the first terminal; the baseband chip receives non-contact information from a second terminal; the non-contact information of the second terminal is subjected to analog-digital conversion, and the non-contact information subjected to the analog-digital conversion is transmitted to the user identification module card on the opened logic channel; the baseband chip receives the non-contact information from the user identification module card on the opened logic channel; and the non-contact information of the user identification module card is subjected to digital-analog conversion, and the non-contact information subjected to the digital-analog conversion is sent to the second terminal. Meanwhile, the invention furthermore discloses the baseband chip and the terminal.

Description

technical field [0001] The invention relates to the field of mobile payment, in particular to a method for realizing non-contact communication, a baseband chip and a terminal. Background technique [0002] Most of the current mobile payment terminals are smart terminals equipped with contactless chips (CLF, Contactless Frontend) chips and supporting Single Wire Protocol (SWP, Single Wire Protocol). When the user swipes the card with this type of terminal, the non-contact acceptance device conducts radio frequency communication with the CLF chip in the terminal to establish a connection and prevent collisions. [0003] The terminal has a built-in SWP-SIM card. When in use, the CLF chip and the SWP-SIM card exchange data based on SWP to complete related transactions. [0004] It can be seen from the above description that the current mobile payment terminal needs to be equipped with a CLF chip inside the terminal, and it needs to use a SWP-SIM card to use it, which will great...
