Abstract
A message broker may initialize, responsive to a connection notification published via vehicle connection to a vehicle-associated topic tree topic to which a service delivery network is subscribed, a lost-connection notification to be published to the topic by the broker upon broker identification of the connection as lost, and when a periodic notification over the connection to the message broker is missed, publish the lost-connection notification to the vehicle-associated topic. A service delivery may receive a message publish request for a vehicle topic via a message broker to which the service delivery network and vehicle subscribe; and send a wakeup message to the vehicle out-of-band from the message broker to request the vehicle to reconnect to the message broker when a type of the message requires the vehicle to be connected to publish the message and the vehicle is disconnected.
