Embodiment Construction

[0069] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments It is a part of embodiments of the present invention, but not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0070] The working mode of an NFC device can be Peer to Peer (Peer to Peer, referred to as: P2P) mode, read-write mode or card simulation mode. Usually, a device that only supports card simulation mode is called an NFC tag in this field. Currently, the NFC Forum defines NFC Tags are type 1, type 2, type 3, and type 4 tags. In the embodiment of th...

Abstract

An embodiment of the present invention provides a near-field communication NFC device communication method, device, and NFC device, wherein the method includes: determining the radio frequency RF protocol supported by at least one NFC target device found; according to the RF protocol level or RF protocol priority, Select an RF protocol for NFC communication from the RF protocols supported by the at least one NFC target device, so as to communicate with the NFC target device corresponding to the selected RF protocol. The near-field communication NFC device communication method, device, and NFC device provided by the embodiments of the present invention solve the problem that the NFC discovery method in the prior art finds an NFC target device that matches the function of the NFCC chip in the local NFC device and the resulting problems DH resource consumption and high power consumption.

Description

technical field [0001] Embodiments of the present invention relate to communication technologies, and in particular to a communication method and device for NFC devices and NFC devices. Background technique [0002] Near Field Communication (NFC for short) technology is a short-distance wireless connection technology, which uses magnetic field induction to realize communication between electronic devices in a short distance. [0003] With the gradual popularization of the NFC technology, many user devices have integrated the NFC function. NFC devices can include a device host (DeviceHost, referred to as: DH), an NFC controller (NFCController, referred to as: NFCC) and a security element (SecurityElement, referred to as: SE), where DH is used to manage NFCC, such as NFCC initialization and configuration and power management, etc.; NFCC is used for data transmission with the target NFC device through the RF interface and antenna; SE is used to provide a secure execution envir...
