Problems solved by technology

If the second magnetic radio frequency device B and the second magnetic radio frequency device C reply to the conflict response at the same time, forming radio frequency interference at the same frequency, the first magnetic radio frequency device cannot reliably receive the conflict response, which greatly affects the conflict detection of the first magnetic radio frequency device Success rate

Embodiment 1

[0030] The second magnetic radio frequency device directly replies with a collision response at a random time point. Specifically, when the second magnetic radio frequency device receives the conflict detection request, it considers that a conflict has occurred, and the second magnetic radio frequency device sets a timeout period, randomly delays for a period of time, and then sends a conflict response. segment, then randomly delay for a period of time, and then send a conflict response...and so on, until it times out. At the same time, the conflict detection request must be sent continuously during the receiving time of the first magnetic radio frequency device, and the time for receiving the conflict response is longer than the maximum random delay time of the second magnetic radio frequency device.

[0031] Such as figure 2 and image 3 Flow charts of related processing of the first magnetic radio frequency device and the second magnetic radio frequency device are respec...

Embodiment 2

[0050] The second magnetic radio frequency device first monitors the radio frequency channel to see if other devices reply a conflict response, and then decides whether to reply a conflict response. Specifically, when the second magnetic radio frequency device receives the conflict detection request, it considers that a conflict has occurred, and the second magnetic radio frequency device randomly delays for a period of time and receives a conflict response to confirm whether there is another second magnetic radio frequency device Responding to conflicting responses. During the random listening time, if no other second magnetic radio frequency device is found to reply to a conflict response, it will reply a conflict response on the radio frequency channel; if it detects that another second magnetic radio frequency device is replying to a conflict response, it will not reply to a conflict response. At the same time, the first magnetic radio frequency device must continuously s...

Abstract

The invention provides a method for improving the success rate of conflict detection. The method is applied to a close range communication system which comprises at least one first magnetic radio frequency device and at least one second magnetic radio frequency device. The method comprises that when the second magnetic radio frequency device receives a conflict detection request sent by the first magnetic radio frequency device, the request is ignored if the second magnetic radio frequency device and the first magnetic radio frequency device are in access, and if not, the second magnetic radio frequency device responds to conflict response at a random time point or monitors channels for responding to the conflict response for some time before responding to the conflict response and responds to the conflict response when no other second magnetic radio frequency device responds to the conflict response. According to the method, the occurrence that a plurality of second magnetic radio frequency devices response to the conflict response simultaneously can be effectively avoided, the continuous co-channel interference cannot occur, the probability of the co-channel interference can be reduced, and the success rate of the conflict detection of the first magnetic radio frequency device is improved.

Description

technical field [0001] The invention relates to the field of wireless communication, in particular to a method for improving the success rate of conflict detection. Background technique [0002] In recent years, by integrating radio frequency modules on mobile phones or mobile phone SIM cards and TF cards, using radio frequency communication between mobile phones and POS machines to realize mobile phone on-site payment has become increasingly popular. At present, there is a solution to detect the magnetic signal strength and magnetic information sent by the card reader through the SIM card or SD card installed in the mobile phone, which integrates a 2.4G radio frequency communication module and a magnetic signal magnetic induction module, to confirm that the mobile phone is reading at a distance. Within a certain range of the card reader, activate the radio frequency module on the card to communicate with the card reader to realize mobile phone on-site payment. [0003] In ...
