Background technique

With the development of wireless multimedia services, people's demand for high data rates and user experience is increasing, which puts high demands on the system capacity and coverage of traditional cellular networks. On the other hand, application scenarios such as public safety, social networking, close-range data sharing, and local advertising have led to an increasing demand for understanding nearby people and things and communicating with Proximity Services (PS). Traditional base station-centric cellular networks have significant limitations in supporting high data rates and proximity services. In this context, D2D technology, which represents a new direction for future communication technologies, has emerged. The application of D2D technology can reduce the burden of cellular networks, reduce the battery power consumption of user equipment, increase the data rate, and improve the robustness of the network infrastructure, which satisfies the requirements of the above high data rate services and proximity services.

At the same time, the D2D technology can work in the licensed band or the unlicensed band, and allows multiple D2D-enabled user equipments (D2D User Equipment, D2D UEs) to have network infrastructure or no network infrastructure. Direct discovery/direct communication. There are three main application scenarios for D2D:

UE1 and UE2 perform data interaction under the coverage of the cellular network, and the user plane data does not pass through the network infrastructure. FIG. 1 is a schematic diagram of device discovery/communication in the prior art, as shown in mode 1 of FIG. 1;

The UE relay transmission in the weak/uncovered area, as shown in mode 2 of FIG. 1, allows the UE4 with poor signal quality to communicate with the network through the UE3 with network coverage nearby, which can help the operator to expand coverage and increase capacity;

Allow equipment in the event of an earthquake or emergency where the cellular network is not functioning properly Direct communication, such as mode 3 in Figure 1, UE5, UE6 and UE7 control plane and user plane do not go through the network infrastructure for one-hop or multi-hop data communication.

The D2D technology generally includes a D2D discovery technology and a D2D communication technology, wherein the D2D discovery technology refers to a technology for determining/determining whether the first user equipment is adjacent to the second user equipment. Generally, D2D user equipment can discover each other by transmitting or receiving discovery signals/information; D2D communication technology refers to a technology in which some or all communication data between D2D user equipments can communicate directly without using a network infrastructure.

For group-type communications, such as large enterprises or professional transportation companies, it is now desirable to have unified management and data interaction for multiple vehicles of the same or similar path or for terminals within a designated area, while these vehicles or The interaction process of the terminal does not want to be known by other terminals, but it is not currently implemented in the prior art.
