Embodiment Construction

[0039] The following descriptions of various embodiments refer to the accompanying drawings to illustrate specific embodiments in which the present invention can be implemented.

[0040] Please refer to figure 1 As shown, the embodiment of the present invention provides a vehicle-mounted remote communication method, including:

[0041] Before initiating a session on the vehicle side or the server side, check whether there is an existing connection, if there is, use the existing connection, if not, establish a new connection;

[0042] Before using the newly established connection to initiate a session, the identity verification is performed between the vehicle end and the server end. After the identity verification is passed, a message is sent according to the specific process. If the identity verification fails, the process is terminated;

[0043] The vehicle end uses the existing connection or a newly established connection to send a heartbeat packet to the server at regular...

Abstract

The invention provides a vehicular remote communication method comprising the following steps: before a session is initiated at a vehicle side or at a server side, whether there is an existing connection is checked, an existing connection is used if there is an existing connection, and a new connection is established if there is no existing connection; before a session is initiated through the newly established connection, authentication is carried out between the vehicle side and the server side, a message is sent according to a specific process after authentication, and the process is stopped if authentication fails; and the vehicle side sends a heartbeat packet to the server side at regular intervals through the existing connection or the newly established connection, and the server is actively disconnected from the vehicle side if the server detects no data packet in a set time. According to the embodiment of the invention, through a short connection method, frequent identity authentication is avoided, traffic is saved, and the connection efficiency is improved. Authentication is needed for a newly established connection, and the safety of communication is ensured. Moreover, waste of server resources caused by long-time occupation of server resources is avoided.

Description

technical field [0001] The invention relates to the technical field of the Internet of Vehicles, in particular to a method for vehicle-mounted remote communication. Background technique [0002] Telematics is a compound word of telecommunications (Telecommunications) and information science (Informatics) for long-distance communication, and usually refers to the vehicle information system that applies wireless communication technology.
