Device discovery method, device discovery processing method and device discovering processing device

The invention provides a device discovery method, a device discovery processing method and a device discovery processing device. The device discovery method includes that a network side entity dispenses wireless resources in a designated area, the wireless resources are required resources in the process of D2D (device to device) discovery; a first device in the designated launches D2D discovery for adjacent devices according to the wireless resources, the network side entity receives discovery signals reported from the adjacent devices, and the discovery signals are received by the adjacent devices, from the first device and correspond to the first device; and the network side entity determines the first device to discover the adjacent devices and/or the adjacent devices to discover the first terminal according to authentication information of the first device and the adjacent devices and the corresponding relation of the discovery signals and the first device. By adopting the above technical scheme, privacy of users in the process of D2D discovery is protected, and meanwhile, control of the network side to the D2D discovery is realized.
