Description

Method and device for realizing point-to-point communication of near field communication

Technical Field

The invention relates to Near Field Communication (NFC) transaction processing technology in the Field of communications, and in particular, to a method and apparatus for implementing Peer-to-Peer (P2P) Communication in Near Field Communication.

Background

As shown in fig. 1, the work flow of the conventional NFC P2P transaction system mainly includes: 1) an application program (APP) and an upper layer application of the device 1 send NFC Data Exchange Format (NDEF) messages to an NFC Controller (Controller); 2) the NFC Controller of the device 1 sends a connection establishing request message to the NFC Controller of the device 2; 3) the NFC Controller of the device 2 receives the connection establishing request message of the device 1 and then sends the connection establishing request message to the APP and the upper application of the device 2; 4) the upper layer application completes the transaction in a networked non-offline transaction mode or completes the information transmission process of the virtual line part through touch again.

In the transaction process, along with the continuous improvement of the requirements of service use scenes and the requirements of users, the technical problems of complexity and network limitation appear in the transaction scenes described above:

problem 1: a single touch using NFC P2P fails to complete the transaction. Due to the limitation of the rule of the mobile phone operating system, if data transmission is performed by using the NFC P2P method, single touch of two devices can only complete one-way data transmission from the device 1 to the device 2, and if the device 2 needs to return data to the device 1, the two devices need to touch again to complete a reverse data response. In the process, the time cost of the user is increased, and compared with single-time link establishment quick transmission of emerging radar link establishment and sound wave link establishment, the user experience in the transaction process is seriously reduced.

Problem 2: if a single-touch data transmission mode is used to improve the user experience, the reverse data response from the device 2 to the device 1 can only be completed in a networking mode due to the limitation of the rule of the mobile phone operating system. And many use scenes in the transaction process are carried out under the condition of no network or poor network conditions, and the use scenes of NFCP2P transaction are limited by the limitation of the network, so that the development of services is greatly restricted.
