VoLTE Base Station Synchronous Speech Coding Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
VoLTE communication systems face resource waste and inconsistent user experience due to single-sided adjustments of speech coding modes and code rates, which are not synchronized between calling and called terminals, leading to potential network congestion and inefficient resource allocation.
Innovation Solution
A method for synchronously adjusting speech coding modes and code rates between calling and called terminals through negotiation, where both sides determine and agree on a final speech coding mode and code rate that optimizes resource usage and prevents mismatch, ensuring both sides support the selected settings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If single-sided adjustment of speech coding mode and code rate is implemented, then device complexity is reduced, but resource allocation efficiency deteriorates and user experience consistency worsens
Solution Approach 1:
The patent implements a feedback mechanism where the base station sends suggested speech coding modes and code rates to the core network, which then provides feedback with final determined parameters. This closed-loop feedback system enables coordinated control between network entities, resolving the contradiction by maintaining relatively simple device operations while achieving efficient resource allocation through network-side coordination and confirmation.
Solution Approach 2:
The core network acts as an intermediary between the base station and terminals. The base station provides suggestions, the core network processes these suggestions considering overall network status, and returns final determined parameters. This intermediary mechanism coordinates resource allocation across the network, improving efficiency and consistency without requiring complex direct control between all network entities.
2Ease of operation
If single-sided adjustment of speech coding mode and code rate is implemented, then ease of operation is improved, but user experience consistency deteriorates
Solution Approach 1:
The feedback mechanism ensures that speech coding parameter adjustments are coordinated across the network. The base station's suggestions are reviewed by the core network, which considers overall network status and provides final determined parameters. This feedback loop maintains operational simplicity at the base station while ensuring consistent user experience through network-wide coordination of parameter adjustments.
Solution Approach 2:
The patent achieves equipotentiality by ensuring both calling and called terminals receive coordinated parameter settings from the core network. This coordination ensures that both sides of a communication session operate with matching speech coding parameters, creating consistent user experience across the network while maintaining simple base station operations.
3Adaptability or versatility
If conservative speech coding settings are selected to ensure compatibility, then adaptability is improved, but communication quality may deteriorate
Solution Approach 1:
The patent implements dynamic parameter selection where the core network determines final speech coding modes and code rates based on real-time network status and terminal capabilities. Rather than using fixed conservative settings, the system dynamically adjusts parameters to achieve optimal balance between compatibility and communication quality, adapting to different network conditions and terminal configurations.
Solution Approach 2:
The system changes speech coding parameters (mode and code rate) based on network status and terminal capabilities. The core network receives suggestions from the base station, processes them considering overall network conditions, and returns final determined parameters that optimize both compatibility and quality. This parameter adjustment mechanism resolves the contradiction by selecting appropriate settings rather than always using conservative defaults.

AI summary
A VoLTE communication method and a base station thereof are disclosed. The method includes: receiving a VoLTE communication request sent by a calling terminal; determining and sending a first suggestion complying with the VoLTE communication carried out by the calling terminal to a network side, the first suggestion including a first suggested speech coding mode and a corresponding code rate thereof; receiving from the network side a final speech coding mode and a corresponding code rate that are determined based on the first suggested speech coding mode and the corresponding code rate; and sending the final speech coding mode and the corresponding code rate to the calling terminal, such that the speech coding mode and the corresponding cod rate may be adjusted synchronously on the both side of the VoLTE communication.
