ABSTRACT:
A central host performs an automated method of updating multiple remote devices. In one embodiment, the host recognizes a predetermined download time and, in advance of the download time, transmits a calendar update to multiple remote devices. The calendar update includes the download time, and the remote devices may utilize the download time to set calendar reminders for entering an active state. Within a short time after reaching the download time, the host pushes download data to the remote devices by broadcasting the download data. In one aspect, the host may receive message acknowledgements from remote devices in response to a first calendar update, and the host may automatically transmit additional calendar updates to any remote devices that did not receive the first calendar update. Additional embodiments involve related methods and the terminal devices that receive the updates.
