File Identification for Bandwidth-Constrained Transmission
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Transmitting large electronic files over limited data communication bandwidth from communications devices, such as wireless devices, is inefficient and strains battery power, as existing methods require direct data transmission rather than file identification and attachment.
Innovation Solution
A method where a communications device selects and identifies electronic files to be attached to a message using an identification, allowing the communications node to attach and transmit the files without sending the files themselves, optimizing bandwidth usage and reducing battery strain.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If large electronic files are transmitted directly from the communications device, then the file can be sent to the recipient, but the available data communication bandwidth is limited and transmission time increases
Solution Approach 1:
The patent extracts the large electronic file from the transmission process and stores it on the communications node server. Only a small identification reference is transmitted through the communication channel, while the actual file content remains on the server. This resolves the bandwidth limitation problem by separating the file data from the transmission stream.
Solution Approach 2:
The communications node server acts as an intermediary between the communications device and the recipient. The server stores the large file and provides it to the recipient upon request, using a small identification reference transmitted by the communications device. This mediator approach enables efficient file sharing without direct large-data transmission through limited bandwidth channels.
2Productivity
If large electronic files are transmitted over the communication channel, then the file can be delivered, but valuable bandwidth is occupied and battery power is strained
Solution Approach 1:
The patent removes the large file data from the transmission path, keeping only a compact identification reference on the communication channel. The actual file remains stored on the communications node server, eliminating the need for energy-intensive transmission of large data volumes while maintaining complete file delivery capability.
Solution Approach 2:
The system creates a reference copy or identifier of the file rather than transmitting the actual file content. This identification reference is small and energy-efficient to transmit, while the full file content is accessed from the server copy stored on the communications node, significantly reducing energy consumption.
3Ease of operation
If the communications device stores large electronic files locally, then files can be attached to messages, but the device requires sufficient storage space and processing power
Solution Approach 1:
The patent extracts the storage burden from the communications device and places it on the communications node server. The device only needs to manage small identification references rather than large file contents, dramatically reducing storage space and processing power requirements while maintaining full file attachment capability.
Solution Approach 2:
The communications node server provides universal storage and file management services for multiple users and devices. Instead of each device requiring its own large storage capacity, the shared server infrastructure provides centralized storage, reducing individual device complexity and enabling file attachment capabilities on resource-constrained devices.

AI summary
Systems and methods are provided for identifying an electronic file that is accessible by a communications node to be transmitted to a recipient. A communications device sends an identification of the electronic file. The communications node receives the identification of the electronic file, identifies the electronic file based on the identification, and accesses the electronic file for transmission to the recipient. The electronic file is not transmitted from the communications device to the communications node.
