WAN Data Access Service for Portable Device Storage Bottleneck
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Portable devices lack the storage capacity to host a majority of digital content and face restrictions due to intellectual property rights, necessitating a platform for flexible, network-independent remote access to digital content stored on other endpoints.
Innovation Solution
A WAN-based data access service facilitates remote data access transactions between endpoints, including servers and portable devices, using communication networks, with digital rights and identity management to support diverse business models and content access, enabling direct or proxied communication sessions and data transfer via protocols like MTP.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If digital content is stored on portable devices, then storage capacity is limited, but portability and accessibility are improved
Solution Approach 1:
A network service acts as an intermediary between portable devices and remote storage endpoints. The service discovers available endpoints, manages communication sessions, and facilitates data transfer protocols, enabling portable devices to access remote content without requiring local storage capacity while maintaining portability benefits
Solution Approach 2:
The system enables portable devices to access digital content from multiple types of endpoints (servers, PCs, consumer electronics) through a universal interface. The network service supports various data access operations (download, upload, sync, stream) and works across different network types (WiFi, cellular, Bluetooth), making the solution broadly applicable
2Productivity
If direct network connection is established between endpoints, then communication efficiency is improved, but network compatibility and connectivity issues worsen
Solution Approach 1:
The network service serves as a mediator that manages direct peer-to-peer communication sessions between endpoints. It handles network discovery, session establishment, and protocol negotiation, allowing efficient direct data transfer while abstracting away network compatibility complexities from the portable device and endpoints
3Reliability
If digital rights management is implemented, then intellectual property protection is improved, but access flexibility and user convenience worsen
Solution Approach 1:
Digital rights and identity management are performed in advance before data access operations. The network service authenticates users, verifies permissions, and establishes authorized access sessions beforehand, ensuring IP protection is maintained while allowing convenient subsequent data operations without repeated authentication
Solution Approach 2:
The system implements automated digital rights management where the network service independently handles authentication, authorization, and permission verification. Users simply present their identity, and the system automatically manages access control, maintaining IP protection without requiring users to manually configure or understand complex rights management settings

AI summary
A wide-area network (“WAN”)-based service enables remote data access transactions between participating endpoints within a group of participating endpoints that includes at least one server and at least one portable electronic device. Each participating endpoint is configured for communication via one or more communication networks and stores the same or different data items on behalf of a user. The WAN-based service maintains information about each participating endpoint in the group and its network accessibility, and also maintains one or more catalogs of available data items. The WAN-based service identifies a communication network available to both participating endpoints, and a direct or proxied communication session is established between the portable electronic device and the other participating endpoint via the communication network. Selected data items are downloaded, uploaded, accessed or synchronized via the communication session. The use of digital rights and identity management techniques in combination with the WAN-based service is also discussed.
