Embodiment Construction

[0048] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. 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.

[0049] The terminal described in the embodiment of the present invention needs to adjust and improve the NFC antenna matching circuit of the terminal before leaving the factory, so that the NFC antenna of the terminal can transmit and receive NFC radio frequency signals in both forward and reverse directions. Wherein, the terminal includes an NFC antenna, an NFC controller, a security module, and the like. The NFC-based signal processing method described in the emb...

Abstract

The embodiment of the present invention discloses a signal processing method and device based on near-field communication NFC, which is applied to a terminal with an NFC function and at least two security modules. The NFC antenna of the terminal can receive the first radio frequency field and the second radio frequency field. The signal of the radio frequency field, wherein the method includes: when receiving the NFC radio frequency signal, judging the radio frequency field to which the NFC radio frequency signal belongs; Corresponding relationship, control the transmission of the NFC radio frequency signal to the security module corresponding to the first radio frequency field; if it is judged that the NFC radio frequency signal is the signal of the second radio frequency field, then according to the preset corresponding relationship between the radio frequency field and the security module, Controlling the transmission of the NFC radio frequency signal to the security module corresponding to the second radio frequency field. The embodiment of the present invention can automatically and quickly transmit the NFC radio frequency signal to the corresponding security module.

Description

technical field [0001] The present invention relates to the technical field of terminals, in particular to an NFC-based signal processing method and device. Background technique [0002] With the development and popularization of terminals (eg, mobile phones, tablet computers, etc.), various smart terminals have become an indispensable part of people's daily life. In addition, with the development and popularization of Near Field Communication technology (Near Field Communication, NFC), most terminals now have NFC functions, and combinations of various NFC solutions emerge in endlessly, such as supporting host-based card emulation (Host- Based Card Emulation, HCE) solution and Single Wire Protocol (Single Wire Protocol, SWP) solution, support dual system dual domain NFC solution, etc. For the above combination of NFC solutions, when a terminal receives an NFC radio frequency signal, the prior art can only transmit the NFC radio frequency signal to a certain fixed security m...
