The method is mainly based on the connection service quality requirement and the planned path given by the Internet of vehicles application and the future time window, and whether resource reservation can be carried out is judged, so that whether the connection quality service requirement is supported and a response corresponding to the reliability is given. In practice, however, the quality of service requirements of the connection given by the in-vehicle terminal may change, and if the wireless communication system is capable of providing more accurate and detailed information of the prediction of the quality of service of the connection, rather than just "supportable" or "unsupported", the in-vehicle networking application may use the information to adjust the associated sensing algorithm, autopilot algorithm, etc.

The scheme mainly provides the connection service quality change which occurs, and can not provide the prediction of the future network connection service. And the system provides uniform notification for the Internet of vehicles, and customized information supply cannot be performed.

After the wireless communication system receives the information, the wireless communication system determines whether the connection service quality prediction configuration requirement can be accepted according to the relevant strategy.
-if accepted, replying to the car networking application for acceptance.
