Embodiment 1

[0042] figure 1 It is a flowchart of a terminal discovery method according to Embodiment 1 of the present invention. Such as figure 1 As shown, the method includes:

[0043] Step S102, the network side entity allocates wireless resources in a specified area, wherein the wireless resources are resources required for a device-to-device D2D discovery process;

[0044] Step S104, after the first terminal in the specified area initiates the D2D discovery process for the neighboring terminal according to the wireless resource, the network side entity receives the discovery signal reported by the neighboring terminal, wherein the discovery signal is received by the neighboring terminal from a discovery signal for the first terminal, and the discovery signal corresponds to the first terminal;

[0045] Step S106, the network side entity determines that the first terminal discovers the adjacent terminal and / or the adjacent terminal discovers the first terminal according to the authen...

Embodiment 2

[0066] This embodiment corresponds to Embodiment 1, and corresponding improvements are made to the D2D discovery process on the terminal side. Figure 4 It is a flowchart of a terminal discovery processing method according to Embodiment 2 of the present invention. Such as Figure 4 As shown, the method includes:

[0067] Step S402, the first terminal acquires the wireless resources required for the D2D discovery process, wherein the wireless resources are resources in a specified area allocated by the network entity and are resources required for the terminal-to-terminal D2D discovery process;

[0068] Step S404, the first terminal initiates a D2D discovery process for adjacent terminals according to the acquired wireless resources;

[0069] In step S406, the first terminal sends a discovery signal to an adjacent terminal, wherein the discovery signal corresponds to the first terminal, and the correspondence between the discovery signal and the first terminal is the same as ...

Embodiment 4

[0093] In this embodiment, you can use Figure 6 shown in the topology, the Figure 6 The interaction process of each entity in can participate in Figure 7 processing steps in . The overall process of D2D discovery is as follows: Figure 7 shown, including,

[0094] In step S702, the base station allocates and broadcasts wireless resources used by wireless terminals when performing D2D discovery.

[0095] In this embodiment, a base station can only allocate wireless resources within the range of the base station and broadcast the wireless resources within the range of the base station, or several base stations can be combined to form a D2D discovery area, and several base stations can be combined Make resource allocation. Each base station broadcasts the radio resources used in the D2D discovery area.

[0096] Step S704, the wireless terminal and the eNB jointly complete the device discovery of the D2D user.

[0097] The so-called device discovery means that the eNB di...

Abstract

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.

Description

technical field [0001] The present invention relates to the communication field, and in particular, to a terminal discovery (discovery), discovery processing method and device. Background technique [0002] In the field of wireless communication, with the rapid development of smart terminals and mobile Internet applications, the requirements for user experience and data volume are getting higher and higher. It is against this background that the device-to-device (D2D) technology is proposed. , The D2D technology breaks the limitation that in the previous Long Term Evolution (LTE) system, two wireless terminal devices must communicate through a base station. D2D technology includes two parts: D2D discovery and D2D communication. D2D discovery refers to the communication between wireless terminal devices. When the distance is close enough to allow direct communication between wireless devices, they can discover each other. D2D communication refers to two wireless terminal dev...
