<p>Disclosed are a method, device and system for establishing a device to device connection, which belong to the technical field of communications. The method comprises: a first device in device to device (D2D) communication sending a D2D authentication request to an MME to which the first device is subordinate, and triggering the MME to authenticate the first device; the first device receiving an authentication response message transmitted by the MME through an eNB, and activating a D2D monitoring and broadcasting function in accordance with the authentication response message; and when the first device monitors the second device in D2D communication, the first device sending a connection establishment request message to the eNB, and triggering the eNB to establish a D2D communication link between the first device and the second device, so that the D2D connection between the two devices is controlled by a network. Thus, an operator can effectively perform the functions of controlling, managing or charging the D2D communication. Meanwhile, compared with the prior art, after establishing a D2D connection, because the network can be effectively controlled, the interference brought to UE by the D2D communication can be further eliminated.</p> |
