<p>Provided in embodiments of the present invention are a method, device, and terminal device for near field communication radiofrequency discovery control. The method comprises: a first NFC host acquires state information used for expressing the state of a near field communication controller (NFCC); and, if the state of the NFCC is idle, then the first NFC host transmits a first radiofrequency discovery command to the NFCC. The embodiments of the present invention provide a radiofrequency communication mechanism for NFC devices in a multi-host infrastructure, where the first NFC host transmits the radiofrequency discovery command to the NFCC only when learning that the state of the NFCC is idle, thus preventing an NFC host from transmitting the radiofrequency discovery command to the NFCC when the NFCC is not in an idle state, and thus preventing the problem of a conflict in a multi-host infrastructure when the NFC host controls the NFCC to conduct radiofrequency communication.</p> |
