Description

基于V2X的数据传输方法、用户终端、车辆及***V2X-based data transmission method, user terminal, vehicle and system

传统的蜂窝通信方式包括直接传输和中继解码转发传输。在直接传输中，用户终端直接发送数据给基站来实现用户与基站的直接通信；在中继解码转发传输中，用户终端发送数据给静止的中继，中继转发数据给基站，其中中继只具备转发和解码功能，并不存储上述数据。Traditional cellular communication methods include direct transmission and relay decoding and forwarding transmission. In direct transmission, the user terminal directly transmits data to the base station to implement direct communication between the user and the base station; in the relay decoding and forwarding transmission, the user terminal transmits data to the stationary relay, and relays the data to the base station, wherein the relay only It has forwarding and decoding functions and does not store the above data.

上述两种传输方式都存在一定局限性，不能够很好的符合未来无线网络期待支持各种各样不同QoS（Quality of Service，质量服务）的要求。主要缺点有：当用户终端位于网络边缘时，若需要发送一个对时延不敏感的文件，其通信所需要的能耗会急剧上升，从而会影响用户终端的电池使用时间，即传统的蜂窝通信方式并不能很好的利用中继的可移动性来有效降低传输所需要的能耗，导致信息传输所需要的能耗较高，缩短了用户终端的电池使用时间。Both of the above transmission methods have certain limitations, and are not well-suited for future wireless networks to support a variety of different QoS (Quality Of Service, quality service). The main disadvantages are: when the user terminal is located at the edge of the network, if it is necessary to send a file that is not sensitive to the delay, the energy consumption required for communication will rise sharply, which will affect the battery life of the user terminal, that is, the traditional cellular communication. The method does not make good use of the mobility of the relay to effectively reduce the energy consumption required for transmission, resulting in higher energy consumption for information transmission and shortening the battery life of the user terminal.

Local Area Networks, WLAN, etc. to transmit data.

具体的，当上述用户终端未处于任意基站的通信覆盖范围内时，检测用户终端的可通信区域内（如方圆100米内）是否存在能够提供数据传输的车辆。其中，上述能够提供数据传输的车辆是指能够与上述用户终端通信连接、且可以接收用户终端上传的数据包的车辆，如具有蓝牙通信功能的车辆、或者设置有无线热点的车辆等。Specifically, when the user terminal is not in the communication coverage of any base station, it is detected whether there is a vehicle capable of providing data transmission in the communicable area of the user terminal (eg, within 100 meters). The vehicle capable of providing data transmission refers to a vehicle that can communicate with the user terminal and can receive a data packet uploaded by the user terminal, such as a vehicle having a Bluetooth communication function or a vehicle provided with a wireless hotspot.

步骤203、当所述用户终端的可通信区域内存在能够提供数据传输的车辆时，则将所述待传输的数据包上传至所述车辆对应的车载通信单元。Step 203: When there is a vehicle capable of providing data transmission in the communicable area of the user terminal, upload the data packet to be transmitted to the in-vehicle communication unit corresponding to the vehicle.

具体的，请参照图3，图3为本发明第二实施例中步骤203的细化步骤的流程示意图，图3中，上述步骤203中所述的将所述待传输的数据包上传至所述车辆对应的车载通信单元的步骤包括：Specifically, please refer to FIG. 3, which is a schematic flowchart of the refinement step of step 203 in the second embodiment of the present invention.

For example, if the user terminal uses Bluetooth for data transmission, and the effective transmission distance of the Bluetooth is 100 m, the optimal transmission distance of the user terminal may be set to 100 m; or, suppose the user terminal uses the wireless hotspot launched by the vehicle. To transmit data, and the effective communication distance of the wireless hotspot transmitted by the above vehicle is 200m, the optimal transmission distance of the above user terminal can be set to 200m.
