Abstract:
Methods provide mechanisms for efficiently delivering files over a broadcast system to mobile devices. Files for broadcast may be logically identified as belonging to a directory in a file system. A Broadcast Schedule Message may inform receiver devices of files that will be broadcast at a specified time, as well as describe the files. File may be transmitted in file delivery pipes, which may be of different bandwidth and data rates. Receiver devices configured according to the embodiments may make use of the broadcast schedule message to select files to be received based on the service or application with which the file is associated, and whether the file is new or an update to a previously received file. Receiver devices activate receiver circuitry to capture the files within their advertised broadcast window, and pass the files to be broadcast to applications or services requesting the files.
