D2D Policy Control via Mobile Entity Self-Reporting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems face challenges in monitoring and managing device-to-device (D2D) communication resource usage, particularly in scenarios where operator-controlled access points have limited capacity to track usage levels, leading to inefficiencies in spectrum bandwidth tracking and monetization.
Innovation Solution
Implementing a system where mobile entities periodically report their resource utilization back to the network, using digital certificates and shared-secret keys for secure accounting and authentication, enabling accurate tracking and billing while mitigating security threats like fraud and misreporting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If operator-controlled access points are used to monitor D2D communication, then network control and security are improved, but the capacity to track usage levels becomes limited and operational costs increase
Solution Approach 1:
The patent divides the monitoring function into two parts: mobile entities self-monitor their own resource usage and generate accounting reports, while access points only need to relay these reports to the network. This segmentation reduces the monitoring burden on access points while maintaining network control through centralized processing of accounting data.
Solution Approach 2:
Mobile entities are enabled to autonomously track their own D2D resource consumption and generate accounting reports without requiring continuous active monitoring by access points. This self-service approach reduces the operational complexity and capacity requirements of the access point infrastructure.
2Productivity
If mobile entities self-report resource utilization, then tracking accuracy and monetization efficiency are improved, but security threats like fraud and misreporting increase
Solution Approach 1:
The patent implements preliminary authentication measures by equipping mobile entities with digital certificates and shared-secret keys before they begin self-reporting. This preliminary security setup enables the network to verify the authenticity of accounting reports and detect fraud, allowing efficient self-reporting while mitigating security risks.
Solution Approach 2:
The network receives accounting reports from mobile entities and provides feedback through policy control decisions and charging actions. This feedback loop includes verification mechanisms that can detect and respond to fraudulent reporting, enabling the system to maintain both efficiency and security through continuous monitoring and adjustment.
3Reliability
If traditional base station infrastructure is used for D2D communication, then network coverage and control are maintained, but resource utilization efficiency and monetization capability decrease
Solution Approach 1:
The patent enables dynamic resource allocation and monitoring for D2D communications, allowing the network to adaptively control and charge based on actual resource usage patterns. This dynamic approach improves resource utilization efficiency while maintaining network control through flexible policy enforcement and real-time accounting.
Solution Approach 2:
The system changes the monitoring parameter from passive network-side observation to active mobile-entity self-reporting with digital certificate verification. This parameter change enables more efficient resource tracking and monetization while maintaining network control through cryptographic authentication and centralized policy management.

AI summary
Systems and methods are provided for providing policy control and charging for device to device (D2D) services. A network entity transmits, to at least one mobile entity, configuration data including device-to-device data, and receives, from the at least one mobile entity, an accounting report associated with device-to-device communication. The network entity transmits, to a charging function entity, a charging report based on the accounting report received from the at least one mobile entity. A policy control function entity performs a policy control and enforcement based at least on the accounting report received from the at least one mobile entity.
