1 . A system for maintaining a connection between a service provider and a remote on board unit, the system establishing an initial time; determining a time of termination; establishing a waiting time between the initial time and a time of delivery; monitoring the connection between the service provider and the on board unit; and sending dummy data at the time of delivery if no activity has occurred during the waiting time. 
     
     
         2 . The system according to  claim 1 , wherein the time of termination is a time when a wireless network terminates the connection between the service provider and the on board unit. 
     
     
         3 . The system according to  claim 2 , wherein the time of delivery is established before the time of termination so that delays associated with the transmission of the dummy data is accommodated. 
     
     
         4 . The system according to  claim 1 , wherein the dummy data is ignored by a party receiving the dummy data. 
     
     
         5 . The system according to  claim 1 , wherein a new initial time is established if activity is detected during the waiting time.
