Abstract
The disclosure provides a communication method. The method includes: receiving a call request forwarded by an operator server, the call request being sent by a calling terminal to the operator server; generating a transferring instruction in response to the call request being a crank call; and sending the transferring instruction to the operator server, such that the operator server establishes a call connection between the calling terminal and a smart device based on the transferring instruction.
