Method and apparatus for establishing quick connection between internet of things devices, and device

A method for establishing a quick connection between Internet of things devices, applied to a target device and comprising:

• receiving a first message broadcasted by a source device, wherein the first message comprises a quick connection request of the source device;
• and
• returning a first response message based on the first message, wherein the first response message is used to establish the quick connection with the source device,
• wherein returning the first response message based on the first message comprises:
• sending the first response message used for acquiring guidance information of the source device to the source device, wherein the guidance information is necessary information required by device provisioning protocol (DPP) authentication and configuration.

A user device, comprising:

• a processor;
• a memory configured to store a processor-executable instruction;
• and
• an input/output interface,
• wherein the processor is configured to:
• when a quick connection is required to be established, control the input/output interface to broadcast a first message based on a Device to Device (D2D) resource, wherein the first message comprises a quick connection request of a source device;
• monitor a first response message corresponding to the first message;
• and
• establish the quick connection with a target device based on the first response message,
• wherein the processor is further configured to:
• monitor the first response message sent by the target device based on the first message and used for acquiring guidance information of the source device, wherein the guidance information is necessary information required by device provisioning protocol (DPP) authentication and configuration.
