Wireless Network dCDN Selection Module
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The exchange of CDNI signaling and the selection of downstream Content Delivery Networks (dCDNs) in wireless communication systems are not efficient or robust, leading to underutilization of local dCDNs in coordination with wireless network CDNs, landline ISP CDNs, and core Internet CDNs.
Innovation Solution
A wireless communication network selects a dCDN for a wireless communication device by processing CDN registration data and signaling from an Upstream Content Delivery Network (uCDN) using wireless device IDs, routing CDN signaling based on device IDs to identify and select the appropriate CDN, and transferring media content efficiently.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If local dCDNs are deployed in wireless communication networks, femtocells, Wifi hotspots, and LANs, then content delivery coverage and accessibility are improved, but coordination and selection efficiency between multiple dCDNs and core Internet CDNs deteriorate
Solution Approach 1:
The patent introduces a dCDN selection module as an intermediary component within the wireless communication network that coordinates between multiple dCDNs and core Internet CDNs. This module receives CDN signaling from uCDN, processes registration data from multiple dCDNs, and makes intelligent selection decisions, thereby resolving the coordination inefficiency while maintaining expanded coverage
Solution Approach 2:
The patent segments the CDN selection function into a dedicated module that operates independently within the wireless network infrastructure. By separating the selection logic from both the core Internet CDN and local dCDN operations, the system can efficiently manage multiple dCDNs without compromising overall coordination efficiency
2Adaptability or versatility
If multiple dCDNs are coordinated with core Internet CDNs, then content delivery versatility is improved, but signaling exchange complexity and robustness deteriorate
Solution Approach 1:
The dCDN selection module serves as a mediator that simplifies signaling exchange between multiple dCDNs and core Internet CDNs. It consolidates registration data from multiple dCDNs and processes uCDN signaling in a unified manner, reducing the overall signaling complexity while maintaining versatility in content delivery options
Solution Approach 2:
The selection module implements universal handling of CDN signaling that works across multiple dCDN types (wireless network CDNs, landline ISP CDNs, core Internet CDNs). This multi-functional approach maintains versatility in supporting different CDN configurations while using a unified processing mechanism to avoid complexity proliferation
3Speed
If dCDN selection is based on proximity and transport efficiency, then content delivery speed is improved, but utilization of local dCDNs deteriorates
Solution Approach 1:
The selection module incorporates feedback mechanisms that consider both transport efficiency metrics and dCDN utilization status. By monitoring the performance and load of local dCDNs, the system can make balanced selection decisions that maintain delivery speed while ensuring adequate utilization of available local resources
Solution Approach 2:
The dCDN selection is implemented as a dynamic process that adapts to changing network conditions, dCDN availability, and content delivery patterns. This dynamic selection mechanism can shift between prioritizing speed and prioritizing utilization based on real-time conditions, resolving the contradiction between the two objectives

AI summary
A wireless communication network serves media content to a wireless communication device. The wireless communication network receives registration notices for the wireless communication device from Downstream Content Delivery Networks (dCDNs) when the wireless communication device registers with the dCDNs. The wireless communication network receives CDN signaling from an Upstream Content Delivery Network (uCDN) for one of the multiple dCDNs when the wireless communication device registers with the uCDN. The wireless communication network selects one of the dCDNs for the wireless communication device. The wireless communication network transfers the CDN signaling to the selected one of the dCDNs. The uCDN transfers media content to the dCDN and the dCDN transfers the media content to the wireless communication device.
