Non-Permanent Media File Delivery for Mobile Stations
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional mobile phones with limited memory capacity face challenges in storing multiple music files, as a single music file can occupy substantial memory, preventing users from experiencing portable digital music without having to actively manage their device's memory by deleting other files.
Innovation Solution
A program of machine-readable instructions that allows for the delivery of non-permanent media files to mobile stations through a wireless network, enabling streaming and automatic deletion after playback, with options for different communication pathways and payment authorization, ensuring the file is not permanently stored.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If a single music file is stored on a mobile station with limited memory, then the user can play digital music on the device, but the memory capacity is quickly exhausted, preventing storage of multiple files
Solution Approach 1:
The patent segments the music storage function into two parts: local temporary storage on the mobile station and permanent remote storage on a server. The mobile station only holds temporary access rights to files rather than permanent copies, allowing multiple files to be accessed without consuming local memory capacity.
Solution Approach 2:
The patent introduces a server as an intermediary between the user's personal computer and the mobile station. The server stores music files permanently and manages temporary licensing to mobile stations, eliminating the need for files to be stored locally on the mobile device.
2Ease of operation
If the user downloads music files to a mobile station, then portable digital music playback is enabled, but the user must actively manage memory by deleting other files
Solution Approach 1:
The system provides self-service memory management through automatic licensing and expiration mechanisms. The server automatically manages file licensing, temporary downloads, and expiration deletion without requiring user intervention. Files are automatically removed from the mobile station when their licensing period expires or when the user purchases permanent copies.
3Quantity of substance
If memory cards are used to extend mobile station memory, then more music files can be stored, but not all mobile station models support this feature
Solution Approach 1:
The patent creates a universal solution that works across all mobile station models regardless of their native storage capabilities. By using a server-based storage system with temporary licensing, the solution provides extended storage functionality to all devices without requiring hardware modifications or specific model support for memory cards.

AI summary
A media file content provider 30 sends a non-permanent copy of a media file, such as a music or video file, to a second mobile station MS 34 in response to a request from a first MS 22. The copy may be rendered non-permanent by streaming it, by encrypting it, and by appending a first instruction to automatically delete it after playing. The first MS 22 may be given an option of delivery pathways, such as cellular 76, 78, WLAN 80, or DVB-H 84. After playing, an offer is made to the second MS 34 to purchase a permanent copy of the media file. If accepted, the content provider may provide another copy of the media file, or preferably a permanent decryption key or a second instruction that defeats the first instruction prior to its deletion of the media file.
