Base Station Delay Management for VoIP
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless VoIP communication systems, deteriorating wireless environments lead to increased delay due to the need for more data slots at lower communication data rates, causing voice quality issues and reducing the number of available users.
Innovation Solution
A base station with a data rate operation/management unit, threshold value operation/management unit, and delay management unit that determines the wireless environment conditions and either skips packets, adjusts slot assignment, or terminates slot transmission to reduce delay, allowing for resource allocation to other users.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the communication data rate is reduced to transmit data in bad wireless environments, then the data can be transmitted to the user terminal with high probability, but the number of necessary data slots increases causing increased delay
Solution Approach 1:
The patent implements dynamic adjustment of communication parameters based on real-time wireless environment conditions. The base station monitors data rate, slot usage, and transmission success rates, then dynamically changes modulation schemes, data rates, and slot allocation to optimize both reliability and delay performance under varying channel conditions
Solution Approach 2:
The patent changes multiple transmission parameters including data rate, modulation scheme, and slot allocation based on wireless environment quality. By adjusting these parameters dynamically, the system achieves high transmission probability in bad environments while controlling delay through intelligent parameter selection
2Reliability
If the number of data slots is increased to transmit one packet at low data rate, then the data can be transmitted to the user terminal, but delay occurs and voice quality deteriorates
Solution Approach 1:
The base station performs preliminary assessment of wireless environment conditions and proactively adjusts transmission parameters before voice quality deteriorates. By predicting channel conditions and pre-adjusting data rates and slot allocations, the system prevents delay-induced voice quality degradation while ensuring reliable transmission
3Reliability
If the number of data slots is increased to transmit one packet, then the data can be transmitted to the user terminal, but the number of available users decreases
Solution Approach 1:
The patent implements dynamic resource allocation where the base station continuously monitors wireless environment conditions for multiple users and dynamically adjusts data rates and slot allocations. This allows the system to maintain high transmission reliability for each user while optimizing overall system capacity and number of available users through efficient dynamic resource management

AI summary
The present invention can be achieved by a base station in which a terminal is accommodated and the terminal is communicated with another terminal, and which includes: a data rate operation/management unit which operates and stores a time-averaged data rate Rave of the terminal; a threshold value operation/management unit which obtains a current communication data rate R of the terminal to operate and store R/Rave; and a delay management unit which controls to reduce delay on the basis of the R/Rave.
