Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional D2D communications lack a global view of connections, leading to inefficient static routing and inability to fully utilize D2D paths, resulting in wasted resources and inefficient traffic management.
Innovation Solution
A D2D connection group is created, where a first device generates a D2D route policy based on proximity information and route selection criteria, allowing for dynamic routing of traffic across multiple applications, enabling a global view of D2D paths and optimizing network efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If static routing is used in D2D communications, then device complexity is reduced, but network efficiency and resource utilization deteriorate
Solution Approach 1:
The patent implements dynamic routing policies where the network can adjust routing paths based on real-time proximity information and network conditions. The system transitions from static pre-configured routes to dynamic route selection that adapts to changing D2D connection states, thereby improving network efficiency without significantly increasing device complexity through automated policy management.
Solution Approach 2:
The system establishes feedback loops where proximity information is continuously collected and used to update routing policies. The network monitors D2D connection status and dynamically adjusts routing decisions based on this feedback, enabling efficient resource utilization while maintaining manageable system complexity through centralized control.
2Productivity
If a global view of D2D connections is implemented, then traffic management efficiency improves, but device complexity and information processing requirements increase
Solution Approach 1:
The patent introduces a network-side intermediary (base station or network controller) that maintains the global view of D2D connections and routing policies. Individual devices do not need to process complex routing information themselves; instead, the network intermediary collects proximity information, determines optimal routes, and distributes routing policies to devices, thereby achieving efficient traffic management without burdening devices with complex processing requirements.
3Productivity
If dynamic routing policies are generated based on proximity information, then network utilization improves, but the complexity of routing control increases
Solution Approach 1:
The system performs preliminary actions by pre-establishing routing policies and proximity information collection mechanisms before actual D2D traffic flows. The network proactively gathers proximity data and prepares routing policies in advance, enabling efficient dynamic routing without requiring complex real-time decision-making at the device level during actual data transmission.
