Description

A method and device for realizing point-to-point communication of near field communication

technical field

The invention relates to a near field communication (NFC, Near Field Communication) transaction processing technology in the communication field, and in particular, to a method and device for implementing near field communication peer-to-peer (Peer to Peer, P2P for short) communication.

Background technique

The existing NFC P2P transaction system is generally shown in Figure 1. In the NFC P2P transaction system, its workflow mainly includes: 1) The application program (APP) of the device 1 and the upper-layer application send the message to the NFC controller (Controller). NFC Data Exchange Format (NDEF, NFC Data Exchange Format) NDEF message; 2) The NFC Controller of Device 1 sends a connection establishment request message to the NFC Controller of Device 2; 3) The NFC Controller of Device 2 receives the connection establishment request message of Device 1 Then send it to the APP and the upper-layer application of the device 2; 4) The upper-layer application completes the transaction by using the networked non-offline transaction method, or completes the information transmission process of the dotted line part by touching it again.

In the transaction process, with the continuous improvement of business usage scenarios and user requirements, in the transaction scenarios described above, there are technical problems that are cumbersome and limited by the network:

Question 1: The transaction cannot be completed with a single touch using NFC P2P. Due to the restrictions of the mobile phone operating system rules, if the NFC P2P method is used for data transmission, a single touch between two devices can only complete one-way data transmission from device 1 to device 2. If device 2 needs to return data to device 1, it takes two The device touches it again to complete the reverse data reply. In this process, it not only increases the time cost of users, but also seriously reduces the user experience in the transaction process compared with the emerging radar connection and sonic connection fast transmission for a single connection.

Question 2: If the single-touch data transmission method is used to improve the user experience, due to the restrictions of the mobile phone operating system rules, the reverse data response from device 2 to device 1 can only be completed through the Internet. Many usage scenarios in the transaction process are carried out in the absence of network or with poor network conditions. Network restrictions also limit the usage scenarios of NFCP2P transactions, which greatly restricts business development.
