A base station can be understood as a public mobile communication base station, a radio transceiver station that transmits information between a mobile communication switching center and a mobile telephone terminal in a certain radio coverage area. The other device is a device other than the early warning device in the device of the serving cell covered by the base station. The early warning device and the base station can communicate wirelessly, and other devices and the base station can communicate wirelessly, and the D2D communication can be performed between the early warning device and other devices. By implementing the network architecture shown in FIG. 1, the early warning device can send the early warning information to other devices in an emergency when the early warning device is in an emergency.

S201. The early warning device sends a D2D communication request to the base station to trigger the base station to allocate a D2D communication channel to the early warning device in response to the D2D communication request.

In the embodiment of the present invention, D2D communication (Device-to-Device Communication) is a new technology that allows devices to directly communicate by multiplexing cell resources under the control of the system.

Generally, users can communicate directly through the D2D channel in addition to communication through the base station service. Each D2D communication channel needs to occupy a certain D2D communication channel resource, where the communication channel resource refers to the radio resource used by both parties participating in the D2D communication (ie, the wireless frequency band). For example, we generally say that GSM has four frequency bands, such as GSM850, GSM900. , GSM1800, GSM1900, etc. The user performing D2D communication needs to obtain the frequency resource and transmission power required for D2D communication under the control of the cell base station.

In the embodiment of the present invention, when an emergency occurs on the road, the early warning device may send a D2D communication request to the base station, and after receiving the D2D communication request, the base station may allocate D2D communication to the early warning device in response to the D2D communication request. a channel, wherein the base station is a base station corresponding to a serving cell where the early warning device is located.
