**5.2 Remote Application Management Service (Remote-AMS)**

One of the main objectives of applications running inside the train is to provide information in order to facilitate the work of the train driver. Usually these applications need to use information generated in the ground centre. If this information changes, it needs to be updated remotely. In addition, there are terrestrial applications that use information generated by some on board applications. Therefore, it is necessary to be able to download that information from trains.

In order to resolve these issues, a new service that allows the remote management of on board applications (upgrade, download and deletion of information) will be proposed. This new service is composed by a terrestrial software module and an on board one that communicate each other to permit this remote management. So, this system would be integrated with the communication architecture described before based in heavy communications scheme (voluminous information with no real-time requirements).
