Abstract
Update data is dispatched by a communication center to terminals with the aid of a broadcasting network. Next, the terminals report their update to the center through a bidirectional network. The center renews a current campaign or stops the campaign as a function of the number of terminals updated. When only a minimum number of terminals need to be updated, the campaign is stopped and the last terminals that were not updated through the campaign transmitted through broadcast network will be updated via the bidirectional link.
