METHODS AND APPARATUS FOR IMPROVING NFC DATA EXCHANGE CONFIGURATION PARAMETER UPDATE MECHANISMS

摘要

Aspects disclosed herein relate to improving mechanisms for prompting a NFCC to update data exchange parameters for ISO-DEP communications between a DH and a remote NFC endpoint. In an example, with a NFC device a DH may be configured to receive an activation message from a NFCC that is using a Frame RF interface over NFC-B RF technology, determine that one or more data exchange parameters included in the activation message are different from one or more corresponding current relevant data exchange parameters that the NFCC is configured to implement, generate an RF parameter update command including the one or more data exchange parameters corresponding to the one or more current relevant data exchange parameters that are determined to be different, and send the generated RF parameter update command to the NFCC to prompt the NFCC to update the one or more corresponding current relevant data exchange parameters.

1. A method of communications, comprising:
sending, by a near field communication controller (NFCC), an activation message to a device host (DH), wherein the NFCC is using a Frame radio frequency (RF) interface over NFC-B RF technology; and receiving a generated RF parameter update command from the DH to prompt the NFCC to update one or more corresponding current relevant data exchange parameters with one or more data exchange parameters included in the RF parameter update command.
