Method, apparatus, and terminal device for near field communication radio frequency communication

摘要

A method for near field communication (NFC) radio frequency communication includes acquiring, second configuration information of established radio frequency communication, where the established radio frequency communication is radio frequency communication that a second NFC host performs with a remote NFC endpoint using a near field communication controller (NFCC); and if the second configuration information matches first configuration information of radio frequency communication to be initiated by the first NFC host, sending, to the NFCC, an activate request command used to activate a radio frequency interface corresponding to the first configuration information, so that the NFCC activates the radio frequency interface and the first NFC host performs the radio frequency communication with the remote NFC endpoint through the radio frequency interface. The embodiments of the present invention provide a radio frequency communication mechanism for an NFC device under a multi-host architecture.

1. A method for near field communication (NFC) radio frequency communication comprising:
acquiring, by a first NFC host, second configuration information of established radio frequency communication, wherein the established radio frequency communication is radio frequency communication that a second NFC host performs with a remote NFC endpoint using a near field communication controller (NFCC), wherein the second configuration information comprises a second radio frequency protocol identifier, and wherein the second radio frequency protocol identifier is used to identify a protocol used for the radio frequency communication between the NFCC and the remote NFC endpoint; and sending, by the first NFC host to the NFCC, an activate request command used to activate a radio frequency interface corresponding to first configuration information when the second configuration information matches the first configuration information of radio frequency communication to be initiated by the first NFC host, wherein the first configuration information comprises a first radio frequency protocol identifier and a radio frequency interface identifier, wherein the first radio frequency interface identifier is used to identify the radio frequency interface corresponding to the first configuration information, wherein the second configuration information matches the first configuration information when the second radio frequency protocol identifier is the same as the first radio frequency protocol identifier, wherein the NFCC activates the radio frequency interface using the second configuration information, and wherein the first NFC host performs the radio frequency communication with the remote NFC endpoint through the radio frequency interface.
