Content Delivery Device for NGN IPTV Integration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current technologies do not effectively enable the integration of Interactive Network Television (IPTV) with Next Generation Networks (NGN), leading to high operation and management costs and the inability to provide unified IPTV services.
Innovation Solution
A content delivery device and method that integrates into the NGN service stratum, connecting between the service control and transmission strata, to manage and optimize content distribution, storage, and delivery to terminal users, utilizing a content delivery control function module and storage function modules that buffer, store, and deliver content based on strategic distribution and location optimization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If IPTV is integrated with NGN using existing separate systems, then service functionality is provided, but operation and management costs are high and unified service delivery is not achieved
Solution Approach 1:
The patent merges the content delivery function into the NGN service control stratum by introducing a content delivery control function module that works closely with the service control function entity. This integration combines previously separate IPTV and NGN systems into a unified architecture, enabling centralized control and reduced operational complexity while maintaining full service functionality.
Solution Approach 2:
The content delivery control function module is designed to handle multiple functions including content distribution, storage management, and delivery control within a single integrated component. This multi-functional design reduces the need for separate specialized systems, thereby lowering operation and management costs while providing comprehensive service capabilities.
2Speed
If content is delivered directly from application function module to terminal user, then delivery speed is fast, but service control and management capability is weak
Solution Approach 1:
The patent introduces a content delivery control function module as an intermediary between the application function module and terminal users. This mediator maintains fast delivery by directly managing content flow to users while simultaneously providing enhanced service control capabilities through its integration with the service control function entity, thus resolving the contradiction between speed and control.
Solution Approach 2:
The content delivery control function module establishes feedback mechanisms with the service control function entity, allowing real-time monitoring and control of content delivery operations. This feedback loop enables the system to maintain high delivery speeds while exercising precise service control and management over the content distribution process.
3Reliability
If multiple content delivery and storage function modules are deployed, then service coverage and reliability are improved, but system complexity and management difficulty increase
Solution Approach 1:
The patent segments the content delivery and storage functions into multiple independent modules distributed across the network. Each module operates autonomously under the coordination of the content delivery control function module, which simplifies management by breaking down the complex system into manageable, standardized units that can be independently deployed and controlled.
Solution Approach 2:
The content delivery control function module dynamically manages the multiple content delivery and storage function modules, adapting their operation and allocation based on real-time service demands. This dynamic control mechanism allows the system to maintain high reliability and coverage while keeping management complexity low through automated, flexible resource allocation rather than static configuration.
