An automobile device receives first data from transmitter(s) located in an automobile. A random access preamble is transmitted on an uplink carrier to a base station in response to a pre-defined condition being met based on the first data or a value of an internal timer or a user input. A time alignment command is received from the base station. Uplink signal transmission timing of the uplink carrier is adjusted according to the time alignment command. A network server transmits, via the base station over a non-GBR bearer, a first message configured to trigger establishment of a connection to the network server. A second message configured to cause transmission of the first data to the network server is received from the network server via the base station over the non-GBR bearer. The first data is encrypted and transmitted to the base station via an established non-GBR bearer.
