Proxy Node Delegation for Wireless Content Delivery
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing wireless communication systems experience significant delays in delivering digital content to wireless devices due to the need for repeated authentication with different proxy nodes each time new content is requested from various content nodes, degrading user experience.
Innovation Solution
A method where a wireless device authenticates with a proxy node, which provides a list of content, and allows the device to request content from other nodes by delegating proxy information, enabling the proxy node to associate with and deliver content from these nodes without requiring repeated authentication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the wireless device authenticates with a different proxy node each time new content is requested from different content nodes, then content delivery security is maintained, but authentication delays increase significantly
Solution Approach 1:
The patent introduces a delegation mechanism where an initially authenticated proxy node acts as an intermediary to facilitate authentication with additional content nodes. The first proxy node, which has already verified the wireless device's credentials, delegates its authentication status to enable access to content on second content nodes through second proxy nodes, eliminating the need for the device to perform full authentication credentials verification with each new proxy node.
2Adaptability or versatility
If the wireless device must authenticate with multiple different proxy nodes for different content nodes, then access control is enforced, but user experience degrades due to repeated authentication requirements
Solution Approach 1:
The patent implements preliminary authentication where the wireless device authenticates with the first proxy node before accessing any content. This initial authentication establishes a delegation relationship that is then reused for subsequent content node accesses. The delegation information, including the first proxy node's identifier and authentication credentials, is stored and automatically utilized when accessing additional content nodes, eliminating the need for repeated authentication actions from the user perspective.
3Reliability
If each content node uses a dedicated proxy node for content delivery, then content node isolation is maintained, but system complexity increases due to multiple authentication management requirements
Solution Approach 1:
The patent enables proxy nodes to serve multiple functions beyond their traditional single-content-node association. The first proxy node, initially associated with the first content node, acquires the capability to facilitate access to second content nodes through delegation. This multi-functionality allows a single proxy node to manage authentication for multiple content nodes, reducing the overall number of authentication management operations required in the system while maintaining content node isolation through the delegation mechanism.

AI summary
Systems and methods of delegating a proxy node for content delivery to a wireless device are provided. A wireless device authenticates with a proxy node, and the proxy node provides to the wireless device a list of content stored on a first content node. If the wireless device requests a second content stored on a second content node, the second content node sends an attachment request to the proxy node, the proxy node associates the second content node with the proxy node, and the proxy node delivers the second content to the wireless device.
