|Title:||COMMUNICATION METHOD, DEVICE AND SYSTEM|
Disclosed in an embodiment of the present invention are a communication method, device and system. The method comprises: a first terminal establishing, by means of D2D technology, a connection with a second terminal; and the first terminal transmitting a voice communication request message to the second terminal, wherein the voice communication request message is used to request the second terminal to transmit a call request. In the present invention, a connection is established between two terminals by means of the D2D technology. After the connection between the two terminals has been established, the first terminal can transmit, to the second terminal, a voice communication request message requesting the second terminal to transmit a call request and make a call on behalf of the first terminal. The above method can be implemented by employing the D2D technology to request assistance from other terminals so as to realize calling. Once a dangerous situation arises, an emergency call can be made by means of the second terminal, thereby improving user experience.
