另一方面，在业务信道上，通过帧长度选择发送策略，可以更好地实现对信道的

On the other hand, on the traffic channel, by selecting the transmission strategy by the frame length, the channel can be used better, and the bandwidth waste and performance caused by the periodic forced switching of the logical channel can be avoided to a very large extent. The problem of descent ensures the communication performance of traditional network data services in the in-vehicle communication network, thereby providing passengers with a good travel experience.

On the other hand, on the business channel, by selecting the sending strategy by frame length, we can better realize the utilization of the channel, avoid the bandwidth waste and performance degradation caused by the periodic forced switching of logical channels to a great extent, and ensure the communication performance of the traditional network data service in the car communication network, so as to provide a good travel experience for passengers.
