File Delivery Framework Using Broadcast Schedule Messages
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems face challenges in efficiently delivering files over broadcast networks to mobile devices, particularly in providing timely and coherent file delivery while managing battery power consumption and scheduling flexibility.
Innovation Solution
The implementation of a File Delivery Framework (FDF) that utilizes Broadcast Schedule Messages (BSMs) to advertise files and datagram packets in advance, leveraging built-in redundancy and error correction mechanisms to ensure timely and effective file delivery, and employing file ingestion systems to manage file scheduling and transmission across multiple file delivery pipes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If files are delivered over broadcast networks using traditional methods, then file delivery can be achieved, but timeliness and coherence of file delivery deteriorate
Solution Approach 1:
The patent implements preliminary action by broadcasting file metadata and delivery schedule information (Broadcast Schedule Messages) before the actual file transmission. This allows receiver devices to prepare for file reception in advance, know when and where to receive files, and coordinate multiple file deliveries coherently. The BSM contains file identifiers, delivery time slots, and resource allocation information that enables timely and coordinated file reception.
Solution Approach 2:
The patent segments file delivery into multiple independent components: file metadata broadcasting (BSM), file content transmission (File Delivery Pipes), and selective reception at receiver devices. This segmentation allows different files to be delivered through separate pipes with independent scheduling, improving overall timeliness and coherence by enabling parallel delivery operations and flexible resource allocation.
2Loss of time
If receiver devices continuously monitor broadcast networks for file availability, then file delivery timeliness improves, but battery power consumption increases
Solution Approach 1:
The patent implements periodic action by having receiver devices monitor broadcast schedule messages at specific intervals rather than continuously. The BSM broadcasting provides periodic updates about file availability and delivery schedules, allowing receiver devices to enter low-power states between monitoring intervals while still maintaining awareness of file delivery opportunities. This reduces battery consumption while preserving timely file delivery capability.
Solution Approach 2:
The patent uses preliminary action by providing advance notification through BSM about upcoming file deliveries, including time slots and resource allocations. Receiver devices can use this advance information to wake up at predetermined times to receive files, rather than continuously monitoring the broadcast channel. This allows devices to sleep during non-delivery periods, significantly reducing power consumption while maintaining timely file reception.
3Adaptability or versatility
If broadcast networks transmit all available files to all receiver devices, then file availability improves, but network resource efficiency deteriorates
Solution Approach 1:
The patent implements local quality by enabling receiver devices to selectively receive only the files they need based on local application requirements and user preferences. The BSM contains file metadata that allows receiver devices to identify and request specific files of interest. File delivery pipes are then allocated to transmit only those selected files to the requesting devices, providing locally optimized file delivery that improves network efficiency while maintaining high file availability for needed content.
Solution Approach 2:
The patent applies dynamics by making file delivery allocation adaptive and flexible. The BSM broadcasting provides dynamic scheduling information that allows receiver devices to request files based on current needs, and the network dynamically allocates delivery pipes and resources based on actual demand. This dynamic approach ensures files are available when needed (high adaptability) while network resources are only used for actual file transmissions (high efficiency).

AI summary
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.
