Virtual DNS record updating method for dynamic IP address change of vehicle hosted server

摘要

A system includes a vehicle modem; a storage maintaining paired device data including phone numbers of mobile devices; and a web server installed to a telematics control unit connected to a vehicle bus. The web server identifies a change in a network address of the vehicle modem, and in response, sends the changed network address to the mobile devices using short message service (SMS) messages addressed to the phone numbers of the mobile devices. A mobile device identifies a web request as including a hostname of a vehicle; accesses a virtual domain name server of the device to determine whether the mobile device locally maintains a network address for the hostname; if so, initiates a web connection to the network address, and if not, initiates the web connection using a network address resolved from the hostname via a remote domain name server.
