Data frame routing processing method, near field communication controller and terminal

Abstract

An embodiment of the present invention provides a data frame routing processing method, a near field communication controller and a terminal, which are used in a first terminal. The first terminal includes a main controller DH and a near field communication controller NFCC. In the first terminal The first routing mechanism is activated, and the method includes: NFCC receives the data frame sent by the second terminal; if the currently activated radio frequency RF protocol is the first RF protocol, the NFCC processes the data frame according to the first preset rule; if the current The activated RF protocol is the second RF protocol, and the NFCC performs routing processing on the data frame according to the first routing mechanism; the first RF protocol includes the near field communication data exchange NFC-DEP protocol, and the second RF protocol includes non-NFC-DEP protocols. By adopting different processing methods for different RF protocol types corresponding to the received data frames, it is realized that when a specific NFCEE is activated, other entities such as P2P applications on the DH can be used normally.

Description

technical field [0001] The embodiments of the present invention relate to the field of wireless communication, and more specifically, to a method for routing and processing data frames in near field communication, a near field communication controller and a terminal. Background technique [0002] Near field communication (near field communication, referred to as NFC) is a short-distance wireless connection technology, based on radio frequency identification (radio frequency identification, referred to as RFID) technology, using magnetic field induction to realize the communication between electronic devices in a short distance. [0003] A terminal with NFC function (hereinafter referred to as NFC terminal) is mainly composed of the following three functional entities: a main controller (device host, referred to as DH), an NFC controller (NFC controller, referred to as NFCC) and an NFC execution environment (NFCExecution Environment, referred to as NFCEE). DH is responsible ...

Problems solved by technology

However, when the data sent by the peer device is P2P data, after the NFCC directly forwards it to the NFCEE, the P2P communication fails because the NFCEE cannot process the P2P data

In addition, when the NFCC receives the RF protocol activation command sent by the peer device, if the first routing mechanism is not available in the current energy state, the NFCC will not respond, and the P2P application protocol will not be activated. That is, P2P communication will not be carried out in the future

[0006] Therefore, when using the above-mentioned first routing mechanism for some NFCEE, although the card simulation application in this NFCEE is available, the P2P application in other entities (such as DH) cannot be used normally
