Embodiment Construction

[0021] Various aspects are now described with reference to the figures. In the following description, for purposes of explanation, numerous specific details are set forth in order to provide a thorough understanding of one or more aspects. It may be evident, however, that the aspect(s) may be practiced without these specific details.

[0022] In general, a device can recognize an NFC target device and / or tag when the device is within range of the coverage area of ​​the NFC target device and / or tag. Thereafter, the device has available information sufficient to allow communication to be established. One form of communication that may be established is a peer-to-peer communication link (eg, an NFC-DEP based communication link). As described herein, communication between devices may be accomplished through a variety of NFC RF technologies such as, but not limited to, NFC-A, NFC-B, NFC-F, and the like. Different remote NFC devices may use different NFC RF technologies and opera...

Abstract

Aspects disclosed herein relate to providing improved selection of NFC radio frequency (RF) discovery cycles based on one or more measurements obtained from one or more sensors associated with a near field communication (NFC) device. In disclosed aspects, an NFC device may be equipped to obtain informational values ​​for the device based on measurements obtained from one or more device sensors. The NFC device may also be equipped to select an RF discovery cycle based on the obtained information value. The NFC device is also operable to perform RF discovery using the selected RF discovery cycle.

Description

[0001] background technical field [0002] The disclosed aspects relate generally to inter-device and / or intra-device communication, and more particularly to methods for improving the detection of NFC radio frequencies based on one or more measurements obtained from one or more sensors associated with a Near Field Communication (NFC) device. (RF) Method and system for selection of discovery cycles. Background technique [0003] Technological advancements have resulted in smaller and more powerful personal computing devices. For example, a wide variety of portable personal computing devices currently exist, including wireless computing devices, such as portable wireless telephones, personal digital assistants (PDAs), and paging devices, each of which is small, lightweight, and easily carried by a user. More specifically, for example, portable wireless telephones further include cellular telephones that communicate voice and data packets over a wireless network. Many such ce...
