Title:
METHOD, DEVICE, AND SYSTEM FOR ADJUSTING PACKET LENGTH IN NEAR FIELD COMMUNICATION (NFC)
Document Type and Number:
WIPO Patent Application WO/2016/187821
Kind Code:
A1
Abstract:
Disclosed are a method, device, and system for adjusting packet length in near field communication (NFC). The method comprises: an NFCC of a first NFC device determines whether or not self is responsible for determining the maximum length value of packets to be transmitted in subsequent communication; if yes, then a first request comprising a first length value is transmitted to a second NFC device, where the first request is used for indicating that the maximum length value of packets to be transmitted in subsequent communication between the first NFC device and the second NFC device be adjusted to the first length value, the first length value is one value determined by the NFCC, and the first request also comprises a first DID; and a first response returned by the second NFC device with respect to the first request and comprising a second DID is received, when the first DID is identical to the second DID, the first length value is used as the maximum length value of packets to be transmitted in subsequent communication. This shows that implementation of embodiments of the present invention allows by means of NCI specifications the implementation of the function for an NFCC and an NFC device serving as a target side to adjust the maximum length value of communication packets in subsequent communication.
