Dynamic Voice Frame Assignment for VoIP and VONR
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In voice over internet protocol (VOIP) and voice over new radio (VONR) systems, a constant number of frames sent for call formation leads to inconsistent user experiences due to resource misallocation, causing call degradation for users farther from the serving cell while wasting resources for those closer, resulting in variable call quality.
Innovation Solution
Implementing a dynamic assignment of voice frames based on a measured radio frequency (RF) signal condition metric, where the number of frames is adjusted according to a predetermined threshold, ensuring optimal resource allocation and quality based on user location and signal strength.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a constant number of frames is sent for call formation, then call management is simplified, but user experience becomes inconsistent and call quality degrades for users farther from the serving cell
Solution Approach 1:
The patent applies dynamics by transitioning from a static, constant frame assignment to a dynamic frame assignment mechanism. The network element continuously monitors RF signal condition metrics and adjusts the number of voice frames dynamically based on real-time signal quality, allowing the system to adapt to changing user positions and network conditions while maintaining consistent call quality.
Solution Approach 2:
The patent changes the parameter of frame assignment from a fixed constant to a variable value based on RF signal condition metrics. By monitoring metrics such as signal strength and quality, the system adjusts the number of frames sent to users according to their actual network conditions, resolving the contradiction between simplified management and consistent quality.
2Reliability
If a constant number of frames is sent to ensure adequate coverage, then users farther from the serving cell receive sufficient frames, but resources are wasted for users closer to the serving cell
Solution Approach 1:
The patent applies local quality by tailoring the frame assignment to individual user conditions rather than applying a uniform approach. Each user receives a customized frame assignment based on their specific RF signal condition metric, allowing distant users to receive more frames when needed while closer users receive fewer frames, thereby eliminating resource waste.
Solution Approach 2:
The system implements feedback by continuously monitoring RF signal condition metrics from users and using this information to adjust frame assignments. This closed-loop mechanism ensures that the network receives real-time information about user conditions and responds accordingly, optimizing resource allocation while maintaining call quality for all users.
3Reliability
If more frames are sent to improve call quality for distant users, then call degradation is reduced, but network resources are allocated inefficiently
Solution Approach 1:
The patent changes the frame assignment parameter from a fixed value to a dynamic value based on RF signal condition metrics. By adjusting the number of frames according to actual user conditions rather than using a constant high value, the system maintains call quality while improving network resource efficiency through precise, needs-based allocation.

AI summary
Aspects provided herein provide methods, systems, and a non-transitory computer storage medium storing computer instructions for dynamic assignment of voice frames in a network. The method begins with measuring a radio frequency (RF) condition metric for a user equipment (UE). The RF condition metric is then compared with a predetermined frame assignment threshold. Based on the comparison, a number of voice frames are dynamically assigned to be sent to the UE.
