Network Voice Path Signal Strength Balancing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing telecommunication systems fail to automatically adjust audio signal strength levels between parties in a call, leading to inconsistent volume levels due to differences in speaker loudness and ambient noise, resulting in frustrating and suboptimal conversation experiences.
Innovation Solution
A method and system that automatically balance audio signal strength levels on voice paths between parties by checking for subscription to the feature, using a balancing bridge to adjust signal levels to a predefined 'normal' level through a feature check module and subscriber database, applicable in both wireless and wireline systems.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual volume adjustment is used, then users can control audio levels, but conversation stability is difficult to achieve and user experience deteriorates
Solution Approach 1:
The system automatically detects audio signal strength levels and adjusts volume without user intervention. The network support node monitors the call paths and autonomously balances audio levels between parties, eliminating the need for manual trial-and-error adjustments while maintaining stable conversation conditions.
Solution Approach 2:
The system continuously monitors audio signal strength levels from both parties and uses this feedback to dynamically adjust volume. The network support node receives audio level information, compares it against desired levels, and automatically makes adjustments to maintain balanced audio, creating a closed-loop control system that ensures conversation stability.
2Extent of automation
If automatic balancing is implemented, then audio signal strength levels are balanced, but system complexity increases
Solution Approach 1:
A network support node is introduced as an intermediary between the two parties. This centralized mediator handles all automatic balancing operations, monitoring audio levels and adjusting volumes without requiring complex distributed systems at each endpoint. The intermediary approach simplifies the overall architecture while achieving automatic balancing.
Solution Approach 2:
The automatic balancing functionality is extracted from the individual telephone devices and placed in the network infrastructure. This separates the complexity of automatic volume control from user equipment, allowing simple handsets to benefit from sophisticated balancing algorithms running in the network without increasing device complexity.

AI summary
Embodiments of the method and system provide for automatic balancing of audio signal strength levels on voice paths between first and second parties in a telecommunication system. The method in an embodiment may have the steps of: checking for a subscription to audio signal strength level balancing by at least one of the first and second parties; and balancing, if at least one of the first and second parties has the subscription, audio signal strength levels on voice paths between the first and second parties. The system implements the method.
