摘要:
The present invention provides a method and system for transmitting and receiving data by a near field communication (NFC) manager in NFC environment, the method comprising: setting control information in a NDEF record; writing, in a NFC tag, the control information or the NDEF record comprising payload data; reading changed control information or changed NDEF record comprising changed payload data from the NFC tag; and determining whether the changed NDEF record is identical to a NDEF record previously read from the NFC tag.

A method and system for handling a plurality of applications in a Near Field Communication (NFC) device is provided. The method is performed at a NFC Controller (NFCC). The method includes storing a source host identity (ID), a destination host ID and a link ID associated with each application from one or more applications. The method also includes managing the one or more applications simultaneously based on the source host ID, the destination host ID and the link ID stored in the NFCC. Problem : how to manage multiple NFC applications on an NFC device simultaneously. Solution : a plurality of applications associated with a Device Host and corresponding Secure Elements are managed by a NFC Controller (NFCC) by creating - logical links . A logical link is used to identify a communication path between the NFCC and the applications residing in the DH, SE or with a remote NFC device. The NFCC manages the applications simultaneously based on the source host ID, the destination host ID and the link ID stored in the NFCC. The link ID is a logical link ID that is generated when the communication between the DH and the SE is established.

Methods and apparatus are provided for controlling a wireless power receiver for wirelessly receiving power. A drive power for driving the wireless power receiver is received from a wireless power transmitter. A communication network is established with the wireless power transmitter. A wireless power network that is controlled by the wireless power transmitter is joined. A charge power is received from the wireless power transmitter.

A peer-to-peer communication method for NFC is provided. A link-level security is started by exchanging a link-level security request and a link-level security response between an initiator terminal and a target terminal, then transmission data are encrypted at link-level security layers of the initiator terminal and the target terminal, and the encrypted data are exchanged between the initiator terminal and the target terminal. The link-level security is released by exchanging a link-level security release request and a link-level security release response between the initiator terminal and the target terminal.

A method and apparatus for controlling charging of a battery by a wireless power receiving apparatus, using a charging power provided from a wireless power transmission device are provided. The method includes initiating charging of a battery by using a charging power provided by a resonator for wirelessly receiving power; determining whether charging of the battery has been completed; and terminating, when the charging of the battery has been completed, an operation of the resonator.

Methods for selectively securing records in a Near Field Communication Data Exchange Format (NDEF) message are provided. One of the methods includes placing a place marker signature record in the NDEF message. The place marker signature record is a modified signature Record Type Definition (RTD). A first set of records preceding the place marker signature record in the NDEF message are unsecured. The method also includes securing the second set of records following the place marker signature record. Another method includes placing a secured bytes field in the signature Record Type Definition (RTD). The secured byte filed indicates number of bytes of data to be secured preceding this field of the signature RTD. The method also includes securing data in records preceding this field in the signature RTD, based on the value of the secured bytes filed.
