Embodiment Construction

[0027] 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 such aspects may be practiced without these specific details.

[0028]Typically, when communicating with a remote NFC device (eg, tag, reader, etc.), contextual information can be used to infer the type of remote NFC device present. For example, context-related information may include, but is not limited to, location information, time or date information, RF technology used during communication, bit rate, amount of available data to be transmitted, analysis of a portion of the data, user interaction, etc. . Accordingly, where information about the remote NFC device can be deduced, it is also possible to omit the NDEF header from the data actually stored on the remote NFC device, thereby reducing overhead st...

Abstract

Methods, apparatus and computer program products for wireless communications are provided in conjunction with improved NDEF message handling. In one example, the communication device is equipped to determine, based on one or more context-related factors, that data received at the NFC device omits at least a portion of the NDEF header, and by adding the missing NDEF header The missing parts are used to generate a complete NDEF message. In another example, the communication device is equipped to receive a complete NDEF message including NDEF header and data and intended to be written to the remote NFC device based on one or more context-dependent factors determining that the remote NFC device is configured to receive a modified version of the complete NDEF message, and generating the modified version of the complete NDEF message by removing at least a portion of the NDEF header.

Description

[0001] Priority claim based on 35 U.S.C. §119 [0002] This patent application claims priority to Provisional Application No. 61 / 714,939, filed October 17, 2012, entitled "METHODS AND APPARATUS FORREDUCING OVERHEAD FOR NFC DATA EXCHANGE PROTOCOL MESSAGES," which is assigned to the Assignee, and is hereby expressly incorporated by reference herein. Background technique [0003] In general terms, the disclosed aspects relate to inter-device and / or intra-device communication, and in particular, to methods for reducing Near Field Communication (NFC) Forum NFC Data Exchange Protocol (NDEF) messages being stored in and / or Methods and systems for overhead when being written to a remote NFC device (eg, tag, reader, etc.). [0004] Improvements in technology have produced smaller and more powerful personal computing devices. For example, a variety of portable personal computing devices now exist, including wireless computing devices such as portable wireless telephones, personal digi...
