Prioritization
All listed vehicle-related services run automatically in the emergency call system control unit. The emergency call system control unit has a priority
management feature to ensure that it does not have to manage several vehicle-related services at the same time. This determines the point at which a
vehicle-related service is to be activated and which vehicle-related service has a higher priority. Depending on which vehicle-related service is to be
activated, the emergency call system control unit releases resources in accordance with the priority list and activates the vehicle-related service or refuses
activation because a vehicle related service with a higher priority is already active. Automatically completing an emergency call has the highest priority.
