Wireless Network Packet Delay Control for Reduced Travel Time
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wireless networks face challenges in reducing packet travel time to user equipment due to queuing delays at base stations, which can impact user experience, especially for packets requiring constant rates for high-quality services.
Innovation Solution
A method and system that estimate parameters indicative of base station service, such as queuing time, to determine whether to delay arrival of data packets, thereby reducing travel time to user equipment, with considerations for packet type and destination.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If data packets are sent continuously to base station, then network throughput is maintained, but packet travel time to user equipment increases due to queuing delays
Solution Approach 1:
The system performs preliminary estimation of base station service parameters (queuing time, round trip time) before sending data packets. Based on these estimates, the system proactively delays packet transmission to prevent queuing delays at the base station, thereby reducing overall packet travel time while maintaining network throughput through intelligent scheduling
2Quantity of substance
If base station services multiple groups simultaneously, then network capacity increases, but service quality for individual packets deteriorates due to increased queuing time
Solution Approach 1:
The system applies different quality levels of service to different data packets based on their characteristics. High-priority packets (e.g., those requiring constant rate for high-quality user experience) receive preferential treatment with minimal delay, while other packets may be delayed to optimize overall system performance. This local differentiation allows the base station to serve multiple groups simultaneously while maintaining service quality for critical packets

AI summary
Examples of methods, systems, and computer program products relating to supervising data in a wireless network are disclosed. At least part of a system may be located between a packet data network and a base station, and/or may be at least logically separate from the base station. The system may be capable of evaluating the service provided by the base station, and may be capable of determining whether or not any action should consequently be performed. Examples of an action may include an action which may not necessarily affect en-route data packets such as outputting a report, and/or an action which may affect en-route data packets such as delaying packets, not delaying packets, and/or stopping the delaying of packets. An action which affects data packets may or may not affect data packets uniformly. An action may or may not result in an improvement in quality of user experience.
