Voice Codec Rate Control via Non-Voice Traffic Mapping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems do not effectively manage voice codec rates during concurrent voice and non-voice communications, leading to suboptimal voice quality due to the lack of consideration for the type and intensity of non-voice activities.
Innovation Solution
A method and system that dynamically adjust the voice codec rate of a user equipment (UE) based on the type and intensity of concurrent non-voice communications, using a mapping table or logic to correlate non-voice communication types with appropriate voice codec rates, and considering additional factors like air interface conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the voice codec rate is set dynamically based on air interface strength, then voice communication reliability is improved, but voice quality deteriorates when high throughput non-voice communication is concurrent
Solution Approach 1:
The patent changes the parameters used for voice codec rate selection from only air interface strength to a combination of air interface strength and non-voice communication type. The system introduces a mapping table that correlates non-voice communication types (video streaming, gaming, web browsing, email) with appropriate voice codec rates, allowing dynamic adjustment of voice codec rate based on both radio conditions and data traffic intensity.
2Ease of manufacture
If a high voice codec rate is used to improve voice quality, then voice communication quality is improved, but system resource consumption increases during concurrent non-voice communication
Solution Approach 1:
The system dynamically adjusts the voice codec rate parameter based on the type of concurrent non-voice communication. The mapping table associates different non-voice communication types with optimal voice codec rates, enabling the system to lower voice codec rates during high-throughput activities like video streaming while maintaining adequate quality for lower-throughput activities like email communication.
3Productivity
If the voice codec rate is reduced to accommodate high throughput non-voice communication, then system resource efficiency is improved, but voice communication quality deteriorates
Solution Approach 1:
The patent implements a mapping table that correlates non-voice communication types with appropriate voice codec rates, allowing the system to optimize the balance between resource efficiency and voice quality. The system selects voice codec rates from available options based on the specific non-voice communication type, rather than uniformly reducing rates for all data communications.
4Ease of manufacture
If the voice codec rate is increased to improve voice quality, then voice communication quality is improved, but air interface throughput capacity decreases
Solution Approach 1:
The system introduces a mapping table that correlates non-voice communication types with appropriate voice codec rates. This allows the voice codec rate to be adjusted based on the data traffic intensity - lower rates are selected for high-throughput activities like video streaming to preserve air interface capacity, while higher rates are selected for low-throughput activities like email to maintain voice quality.

AI summary
A method and system for managing voice codec rate used for voice communication by a user equipment device (UE). In accordance with the disclosure, the voice codec rate will be established (e.g., set or modified) based on a consideration of what type or types of non-voice communication the UE will engage in or is engaging in concurrently with the voice communication.
