Procedures and devices to improve the mechanisms for updating NFC data exchange configuration parameters

摘要

A communications procedure, comprising: receiving (518, 612), by a host device, DH, an activation message from a near field communication controller, NFCC, which is using a frame radio frequency (RF) with NFC-B RF technology; the procedure being characterized by: determining that one or more data exchange parameters included in the activation message are different from one or more current corresponding parameters of relevant data exchange that the NFCC is configured to implement; generating an RF parameter update command that includes the one or more data exchange parameters, corresponding to one or more current relevant data exchange parameters that are determined to be different; and sending (524, 624) the generated RF parameter update command to the NFCC to induce the NFCC to update the one or more corresponding current relevant data exchange parameters with the one or more data exchange parameters included in the command RF parameters update.
