Solution Overview
Problem
Mass market digital communications networks face user capacity constraints due to increasing bandwidth demands, leading to degraded network service experiences and higher service provider costs, with existing technologies failing to meet growing digital networking needs.
Innovation Solution
Implementing a secure execution environment with hardware-based partition techniques for device-assisted services, including secure memory, modems, and monitoring points to enhance service measurement and control integrity, using encrypted communication links and protected execution partitions to safeguard device-assisted service agents.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If network capacity is increased through higher bandwidth applications and content, then user service consumption is improved, but service provider costs increase and network service experience degrades
Solution Approach 1:
The patent segments the service measurement and control functions into dedicated hardware components (service measurement agents, service control agents) that operate independently within the network infrastructure. This segmentation allows for specialized handling of high-bandwidth traffic while maintaining overall network reliability through distributed control mechanisms.
2Adaptability or versatility
If device-assisted service agents are implemented without secure execution environment, then service measurement and control functionality is provided, but the system becomes vulnerable to hacking and malware attacks
Solution Approach 1:
The patent introduces a service execution environment (SEE) as an intermediary layer between the service agents and the underlying hardware/software infrastructure. This SEE acts as a mediator that provides secure isolation, preventing malware and hacking attempts from compromising the service measurement and control functions while allowing the agents to perform their designated tasks.
3Productivity
If service usage measurement and control is not accurately enforced, then network resource allocation can be optimized, but service quality and provider profits deteriorate
Solution Approach 1:
The patent implements feedback mechanisms where service measurement agents continuously monitor service usage and provide real-time data to service control agents. The control agents then adjust resource allocation and enforce service quality policies based on this feedback, creating a closed-loop system that optimizes network resource allocation while maintaining service quality standards.
