The invention discloses an electric vehicle battery charging information transmission method based on an Internet of Vehicles system. The method comprises the following steps: a relay transmission node establishes communication connection with a plurality of vehicle-mounted mobile terminals, and determines whether to communicate with a first vehicle-mounted mobile terminal on a licensed frequencyband or to communicate with the first vehicle-mounted mobile terminal on an unlicensed frequency band; if it is determined that communication with the first vehicle-mounted mobile terminal is to be performed on the licensed frequency band, the relay transmission node notifies the first vehicle-mounted mobile terminal to perform communication on the licensed frequency band; the first vehicle-mounted mobile terminal collects battery state information of the electric vehicle; in response to the collected battery state information of the electric vehicle, the first vehicle-mounted mobile terminalsends a cache state report to the relay transmission node; in response to receiving the buffer status report, an uplink grant for the first in-vehicle mobile terminal is generated by the relay transmission node.

    本发明公开了一种基于车联网系统的电动汽车电池充电信息传输方法,包括如下步骤:由中继传输节点与多个车载移动终端建立通信连接,并确定是将要在许可频带上与第一车载移动终端进行通信,还是将要在未许可频带上与第一车载移动终端进行通信;如果确定将要在许可频带上与第一车载移动终端进行通信,则由中继传输节点通知第一车载移动终端在许可频带上进行通信;由第一车载移动终端收集电动汽车电池状态信息;响应于收集电动汽车电池状态信息,由第一车载移动终端向中继传输节点发送缓存状态报告;响应于接收到缓存状态报告,由中继传输节点生成用于第一车载移动终端的上行链路授权。
