Voice Call Bandwidth Allocation for Stable VoWiFi and VoLTE Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing VoWiFi call solutions suffer from unstable call quality due to network speed and resource allocation issues, leading to call interruptions and poor user experience.
Innovation Solution
A method that determines the current network environment level based on network parameter information, allocates bandwidth to voice calls accordingly, and switches to another network if necessary to maintain call quality and continuity, using VoWiFi or VoLTE networks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If VoWiFi call is made while watching video, then user can use Wi-Fi for both video and voice, but network bandwidth for VoWiFi call becomes low resulting in call interruption
Solution Approach 1:
The system dynamically adjusts bandwidth allocation based on real-time network conditions and service types. When video streaming is detected, the system dynamically reduces VoWiFi bandwidth allocation to ensure video quality, and dynamically switches to VoLTE when bandwidth becomes insufficient, thus resolving the contradiction between multi-service utilization and call stability
Solution Approach 2:
The system changes the bandwidth parameter allocation dynamically. By monitoring network conditions and service types, it adjusts the bandwidth assigned to VoWiFi calls in real-time, reducing bandwidth when video is detected and switching to alternative networks when necessary, thereby maintaining call quality while allowing flexible network usage
2Productivity
If bandwidth is allocated to VoWiFi call, then call can proceed, but network speed problems reduce call quality
Solution Approach 1:
The system continuously monitors network conditions and call quality parameters, using this feedback to adjust bandwidth allocation in real-time. When network speed deteriorates or call quality metrics degrade, the feedback mechanism triggers bandwidth reduction or network switching to maintain acceptable call quality while preserving call continuity
Solution Approach 2:
The system introduces an intermediary mechanism that monitors network conditions and mediates between video streaming and VoWiFi call requirements. This intermediary layer detects network status and orchestrates bandwidth adjustment or network switching, preventing direct conflicts between services and maintaining both call continuity and quality
3Reliability
If network switching is implemented to maintain call quality, then call stability improves, but system complexity increases
Solution Approach 1:
The system performs preliminary actions by pre-configuring network switching policies and bandwidth allocation rules before actual calls occur. By establishing predetermined thresholds and switching conditions, the system simplifies real-time decision-making and reduces operational complexity while maintaining reliable call quality through automated pre-planned responses
