Adaptive Traffic Control via Policy Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current traffic transmission control methods in mobile communication systems cannot effectively detect load or traffic congestion at the cell level, leading to inefficient data transmission and network idleness when there are no user-level traffic requests, resulting in reduced network usability.
Innovation Solution
A terminal device equipped with a signal generator, policy manager, traffic transceiver, network detector, and traffic control processor that generates traffic request signals, detects network status, and controls data transmission based on policy answers from a policy provider, allowing for adaptive non-real-time traffic management to optimize network resource usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If transmission control is implemented at the network layer (L3) with best effort policy, then real-time traffic transmission is enabled, but network load detection capability is lost and congestion cannot be effectively managed
Solution Approach 1:
The patent introduces a new dimension of control by implementing traffic control at the application layer (L7) rather than relying solely on network layer (L3) control. This dimensional shift enables terminals to actively detect network status through policy answer signals and adjust their traffic transmission accordingly, thereby recovering network status detection capability while maintaining transmission efficiency.
Solution Approach 2:
The patent establishes a feedback mechanism where terminals receive policy answer signals from the policy provider that contain network status information. Terminals use this feedback to adaptively control their traffic transmission, creating a closed-loop system that enables both efficient transmission and effective congestion management through continuous network status monitoring.
2Reliability
If terminals continuously retry transmission after packet loss, then data transmission reliability is improved, but network congestion is exacerbated
Solution Approach 1:
The patent implements dynamic transmission control where terminals adjust their retry behavior based on real-time network status detection. Instead of continuous retry attempts, terminals dynamically modify their transmission strategy by pausing or reducing traffic when congestion is detected through policy answer signals, thereby maintaining reliability while preventing throughput degradation.
Solution Approach 2:
The patent changes the parameter of transmission timing by introducing adaptive delays and rate adjustments based on detected network status. Terminals modify transmission parameters such as retry intervals and data rates according to network conditions, enabling reliable transmission without continuously exacerbating congestion.
3Reliability
If network resources are reserved for potential traffic requests, then service availability is improved, but network usability decreases during idle periods
Solution Approach 1:
The patent implements preliminary action by having terminals proactively detect network status and adjust their transmission plans before congestion occurs. Through policy answer signals, terminals receive advance information about network conditions and can pre-adjust their traffic patterns, ensuring service availability when needed while avoiding unnecessary resource reservation during idle periods.
Solution Approach 2:
The patent employs periodic action through cyclic policy inquiry mechanisms where terminals periodically request and receive policy answer signals from the policy provider. This periodic detection and adjustment cycle enables the system to maintain service availability by being ready to transmit when network conditions are favorable, while naturally reducing resource usage during idle periods when traffic requests are absent.

AI summary
A terminal device includes: a signal generator to generate a traffic request signal; a policy manager to transmit a policy request signal to a policy provider, and to receive a policy answer signal corresponding to the policy request signal; a traffic transceiver to perform a download of a traffic answer signal corresponding to the traffic request signal from a content provider via a path network; a terminal network detector to detect a network status of the path network based on the policy answer signal; and a traffic control processor, at a time of the download, to determine a traffic control status based on the network status, and control the download based on the traffic control status.
