METHODS AND APPARATUS FOR IMPROVING RE-ACTIVATION OF A NFC-F BASED REMOTE NFC DEVICE

摘要

Techniques for improving re-activation of an NFC-F based remote near field communication (NFC) device are described. A polling NFC device may be configured to determine that an NFC-F based remote NFC device was previously deactivated, and transmit a sense request message to enable the remote NFC device to receive an attribute request message as part of a device activation procedure. A polling NFC device may be configured to set a sleep flag to indicate that a deselected NFC-F based remote NFC device is in a sleep sub-state. The polling NFC device may be configured to determine that the remote NFC device is to be activated as a type 3 tag, as part of a device activation procedure, and reset the sleep flag to indicate that the remote NFC device is no longer in the sleep sub-state based on the determination.

1. A method of inductive communications, comprising:
determining, by a polling near field communication (NFC) device, that a remote NFC device that is supported by an NFC-F access technology was previously deactivated; and transmitting a sense request message to enable the remote NFC device to receive an attribute request message as part of a device activation procedure.
