NFC configuration method, NFC data transmission method, controller, and NFC controller

摘要

An NFC configuration method. A controller sends data and a parameter of the data to an NFC module for storage or sends a storage space application instruction to an NFC module, such that storage space is reserved for data in the NFC module. Therefore, when data is sent or received in an NFC High manner, the sent data can be acquired from the NFC module or the received data can be stored in the NFC module without participation of a DH, thereby reducing load of the DH.

主权项

1. A near field communication (NFC) data transmission method, the method comprising:
establishing, by an NFC controller of an electronic device, an NFC link between the electronic device and an NFC device; determining, by the NFC controller, a value of an identifier of a storage space and a value of an address of the storage space based on a relationship and a Link Service Class (LSC) of the established NFC link, wherein the relationship linking the address of the storage space, the identifier of the storage space, a type of application-layer data, and a LSC supported by the type of application-layer data, wherein the relationship is stored in the NFC controller, and wherein the storage space is located in the NFC controller; sending, by the NFC controller, a data acquisition instruction to the storage space identified by the value of the address of the storage space and the value of the identifier of the storage space; receiving, by the NFC controller, an application-layer data sent by the identified storage space; and sending, by the NFC controller, the application-layer data to the NFC device via the NFC link.
