Method, device and system for radio frequency device pairing

A method for radio frequency device pairing, comprising:

• after a discovery request message sent by a first radio frequency device is received, returning a discovery response message to the first radio frequency device;
• after a first paring request message sent by the first radio frequency device is received, returning a first paring response message to the first radio frequency device, and displaying interface information, wherein the interface information is prompt information that gives a prompt about a button required to be entered by a user;
• receiving a second pairing request message sent by the first radio frequency device, wherein the second pairing request message contains button information corresponding to a button instruction entered by the user according to the interface information;
• if it is determined that the button information and the interface information are successfully matched, returning, to the first radio frequency device, a second pairing response message which contains a confirmation result, wherein the confirmation result indicates that the button information and the interface information are successfully matched;
• and
• exchanging keys with the first radio frequency device, and prompting a user end that a pairing process succeeds.

A radio frequency device, comprising:

• a user instruction receiving unit, configured to receive a pairing instruction entered by a user;
• a discovery request sending unit, configured to, after the user instruction receiving unit receives the pairing instruction entered by the user, send a discovery request message to at least one second radio frequency device;
• a discovery response receiving unit, configured to receive a discovery response message returned by the at least one second radio frequency device;
• a first pairing request sending unit, configured to send a first pairing request message to a target second radio frequency device in the at least one second radio frequency device;
• a first pairing response receiving unit, configured to receive a first pairing response message returned by the target second radio frequency device;
• a second pairing request sending unit, configured to, after a button instruction entered by the user according to interface information displayed by the target second radio frequency device is received, send a second paring request message to the target second radio frequency device, wherein the second pairing request message contains button information corresponding to the button instruction, and the interface information is prompt information that gives a prompt about a button required to be entered by the user;
• a second pairing response receiving unit, configured to receive a second pairing response message which is returned by the target second radio frequency device and contains a confirmation result;
• and
• a key exchanging unit, configured to, if the confirmation result indicates that the button information and the interface information are successfully matched, exchange keys with the target second radio frequency device, thereby completing a pairing process with the target second radio frequency device.

A radio frequency device, comprising:

• a discovery request receiving unit, configured to receive a discovery request message sent by a first radio frequency device;
• a discovery response returning unit, configured to return a discovery response message to the first radio frequency device;
• a first pairing request receiving unit, configured to receive a first pairing request message sent by the first radio frequency device;
• a displaying unit, configured to display interface information after the first pairing request receiving unit receives the first pairing request message sent by the first radio frequency device, wherein the interface information is prompt information that gives a prompt about a button required to be entered by a user;
• a first pairing response returning unit, configured to return a first pairing response message to the first radio frequency device;
• a second pairing request receiving unit, configured to receive a second pairing request message sent by the first radio frequency device, wherein the second pairing request message contains button information corresponding to a button instruction entered by the user according to the interface information;
• a second pairing response returning unit, configured to, if it is determined that the button information and the interface information are successfully matched, return, to the first radio frequency device, a second pairing response message which contains a confirmation result, wherein the confirmation result indicates that the button information and the interface information are successfully matched;
• and
• a key exchanging unit, configured to, after the second pairing response returning unit returns the second pairing response message which contains the confirmation result indicating that the button information and the interface information are successfully matched, exchange keys with the first radio frequency device, and prompt a user end that a pairing process succeeds.

A non-transitory computer-readable storage medium having a computer program code which, when executed by a hardware processor causes the hardware processor to execute the following steps:

• after a paring instruction entered by a user is received, sending a discovery request message to at least one second radio frequency device;
• receiving a discovery response message returned by the at least one second radio frequency device;
• sending a first pairing request message to a target second radio frequency device in the at least one second radio frequency device;
• receiving a first paring response message returned by the target second radio frequency device;
• after a button instruction entered by the user according to interface information displayed by the target second radio frequency device is received sending a second paring request message to the target second radio frequency device, wherein the second pairing request message contains button information corresponding to the button instruction, and the interface information is prompt information that gives a prompt about a button required to be entered by the user;
• and
• receiving a second pairing response message which is returned by the target second radio frequency device and contains a confirmation result;
• and if the confirmation result indicates that the button information and the interface information are successfully matched, exchanging keys with the target second radio frequency device, thereby completing pairing with the target second radio frequency device.
