Abstract: A method, system, and medium are provided for dynamically switching between unicast and broadcast carriers for delivering content in a mobile network. A first listing of channels is provided to a client mobile device, wherein a first unicast content stream is associated with a first channel. A determination is made to provide an event through a broadcast carrier over the first channel. The first content stream is disassociated with the first channel, and the broadcast event is associated with the first channel. A broadcast alert is communicated to the client mobile device to indicate the change. A second listing of channels is provided to the client mobile device.

Abstract: Disclosed herein is a method and system for managing transmission of media to a plurality of subscribers. As a general matter, a media management system determines that a more than a threshold number of subscribers scheduled to receive a given media transmission are located within a common zone (e.g., common wireless coverage area, common geographically-defined area, etc.), and the system responsively (i) divides the subscribers in the common zone into two or more groups and (ii) transmits the media to the groups sequentially. Preferably, the system waits a period of time between transmission to each group.
