Methods and apparatus for improving a NFCEE discovery process

摘要

Aspects disclosed herein relate to providing a mechanism by which an NFCC can provide a DH with sufficient information to begin RF Discovery on behalf of a NFCEE. In one example, with a NFC device a DH may be configured to receive a discovery request notification from a NFCC indicating a NFCEE is requesting that the DH perform a discovery process. The discovery request notification may include information formatted to simplify the creation of a RF discovery command. The DH may further be configured to determine whether to generate the RF discovery command using the information included in the discovery request notification, generate the DH based discover command using the information included in the discovery request notification upon a determination to include the received information, and transmit the RF discovery command to the NFCC.

主权项

1. A method of communication, comprising:
receiving, by a device host (DH) of a near field communication (NFC) device, a discovery request notification from a near field communication controller (NFCC) of the NFC device indicating that a near field communication execution environment (NFCEE) is requesting that the DH perform, via the NFCC, a discovery process, the discovery request notification including information formatted to simplify creation of a radio frequency (RF) discovery command by the DH; determining whether to generate the RF discovery command using the information included in the discovery request notification; generating, by the DH, the RF discovery command using the information included in the discovery request notification upon a determination to include the received information; and transmitting the RF discovery command from the DH to the NFCC, wherein the information comprises an RF technology and a mode parameter.
