Communication method and apparatus for NFC device and NFC device

摘要

A communication method and apparatus for a near field communication (NFC) device and the NFC device, where the method includes determining a radio frequency (RF) protocol supported by at least one discovered target NFC device; and selecting, according to an RF protocol level or an RF protocol priority, an RF protocol for performing NFC from the RF protocol supported by the at least one target NFC device so as to perform communication with a target NFC device corresponding to the RF protocol determined by selection. The communication method and apparatus provided in the embodiments of the present invention solve a problem that a probability of finding a target NFC device matched with an NFC controller (NFCC) chip function on a local NFC device is low and a problem that device host (DH) resource consumption and power consumption incurred thereof are high.

主权项

1. A communication method performed by a first near field communication (NFC) device that comprises a computer processor coupled to a NFC controller (NFCC), the method comprising:
obtaining NFC radio frequency (RF) protocol priority information for a plurality of NFC RF protocols supported by the first NFC device; determining, by the NFCC, one or more NFC RF protocols supported by a second NFC device; selecting, according to the NFC RF protocol priority information, a selected NFC RF protocol from the one or more RF protocols supported by the second NFC device; and performing, by the NFCC, NFC communication with the second NFC device using the selected NFC RF protocol.
