Embodiment approach

[0858] As an implementation manner, the communication device may further include:

[0859] The memory 264 is used to store programs executed by the processor 262 .

[0860] In the above technical solution, on the basis of the above embodiment, the above request message includes the first configuration information, and after the server receives the first configuration information, the server can use the first configuration information after receiving the first configuration information. The information is sent to the target device. After receiving the first configuration information, the target device can use the first configuration information to establish direct device-to-device communication with the source device. At the same time, it can also realize the control and management of the direct communication process from device to device on the network side, so as to ensure the communication service quality between devices.

Abstract

Provided in an embodiment of the present invention is a communication method, comprising: a source device transmits a request message to a server via an MME, the request message instructing the source device to establish a direct device-to-device communication with a target device, and containing the identifier of the target device, such that the server can use the identifier of the target device to identify the target device and transmit to the target device a request message for activating the direct device-to-device communication function; the source device receives the first configuration information of the target device transmitted by the server via the MME, the first configuration information being used for the direct device-to-device communication; the source device uses the received first configuration information to transmit to the target device a request for establishing the direct device-to-device communication, and establishes the direct device-to-device communication with the target device. Correspondingly, also provided in the embodiment of the present invention are a communication device and system. The embodiment of the present invention enables a network to control the direct device-to-device communication between a source device and a target device.

Description

technical field [0001] The present invention relates to the communication field, in particular to a communication method, device and system. Background technique [0002] In the current device-to-device direct communication technology, the establishment of device-to-device direct communication does not require network management and control. Two devices can directly establish device-to-device direct communication, and then perform data transmission and exchange. Currently, there are various technologies supporting direct device-to-device communication, such as Bluetooth, Ultra Wide Band (UWB) and IEEE802.11-based Wireless Local Area Networks (WLAN) technologies. [0003] The existing device-to-device direct communication occurs directly between two devices, and the network cannot participate in the management and control of device-to-device direct communication, so it is difficult to guarantee the communication service quality between devices.
