Solution Overview
Problem
Existing access networks, such as wireless and wireline networks, face capacity constraints due to increasing user demands for high-bandwidth applications, leading to degraded network service experiences and increased service provider costs, which negatively impact profitability.
Innovation Solution
Implementing a secure device data record (DDR) processing system in wireless communication devices with a secure execution environment to monitor and generate ordered device data records, ensuring compliance with access policies and detecting tampering or malicious software, and restricting network access if policies are violated.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If network capacity is increased to meet growing digital networking demand, then user service consumption capability is improved, but service provider costs increase and profitability is negatively impacted
Solution Approach 1:
The system implements self-service through automated service usage monitoring and billing verification at the network edge. Device data records are automatically generated and verified by the service gateway, enabling the network to self-regulate service consumption without manual intervention, thereby controlling costs while supporting high-bandwidth applications
Solution Approach 2:
The patent implements feedback mechanisms by verifying device data records against service usage reports and generating usage verification records. This closed-loop feedback system monitors service consumption in real-time, allowing the network to adjust resource allocation and billing based on actual usage patterns, optimizing the balance between service capacity and cost
2Measurement precision
If service usage monitoring is implemented to ensure accurate billing, then billing accuracy is improved, but device complexity and processing overhead increase
Solution Approach 1:
The service gateway acts as an intermediary between the device and the billing system. It receives device data records, verifies them against service usage reports, and generates usage verification records. This intermediary approach simplifies device complexity by offloading verification processing to the gateway while maintaining billing accuracy through systematic validation
Solution Approach 2:
The monitoring system is segmented into distinct functional components: device data record generation, service usage report generation, verification process, and usage verification record generation. This segmentation distributes processing overhead across multiple stages and components, reducing the burden on any single device while maintaining comprehensive billing accuracy
