Abstract
A method for establishing a local communication link includes: generating and sending a local communication negotiation request to a cloud server in response to detecting a first local communication operation between the client and a smart device. The local communication negotiation request is configured to instruct the smart device to allocate a TCP port and feed back a local communication negotiation response carrying a port number of the TCP port to the cloud server, and the local communication negotiation response is forwarded by the cloud server to the client. The method also includes after receiving the local communication negotiation response from the cloud server, sending a first link request carrying the port number to the smart device, and establishing a first TCP link with the smart device, the TCP link being a local communication link.
