Persistent Voice Storage for Communication Reliability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless and wired voice communication systems fail to maintain communication when network conditions are poor, leading to dropped calls and loss of voice media due to insufficient usable bit rate, with no persistent storage of conversations to retrieve or review.
Innovation Solution
Implementing persistent storage of voice media on communication devices, allowing transmission and reception from storage when network conditions are inadequate, extending network range and capacity, and enabling communication even when live connections are not possible.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If persistent storage of voice media is implemented, then communication can continue when network conditions are poor, but device complexity increases
Solution Approach 1:
Voice media is stored in persistent storage before network transmission is attempted. This preliminary action allows the system to have communication content ready to transmit when network conditions improve, eliminating the need for real-time network availability and enabling communication continuity despite poor network conditions.
2Length of moving object
If voice media is transmitted from persistent storage when network bit rate is insufficient, then communication range is extended, but loss of time increases due to latency
Solution Approach 1:
The system dynamically adjusts transmission timing based on network conditions. When network bit rate is sufficient, real-time transmission occurs with minimal latency. When bit rate is insufficient, the system switches to transmitting from persistent storage, accepting increased latency but maintaining communication capability. This dynamic adaptation resolves the contradiction between extending range and minimizing time loss.
3Speed
If live communication is required, then real-time interaction is achieved, but communication fails when network bit rate is insufficient
Solution Approach 1:
The system changes the operational parameter from real-time transmission to storage-based transmission when network bit rate falls below the threshold required for live communication. This parameter change allows communication to continue using stored voice media, sacrificing real-time speed but maintaining reliability under poor network conditions.

AI summary
A method for gracefully extending the range and/or capacity of voice communication systems is disclosed. The method involves the persistent storage of voice media on a communication device. When the usable bit rate on the network is poor and below that necessary for conducting a live conversation, voice media is transmitted and received by the communication device at the available usable bit rate on the network. Although latency may be introduced, the persistent storage of both transmitted and received media of a conversation provides the ability to extend the useful range of wireless networks beyond what is required for live conversations. In addition, the capacity and robustness in not being affected by external interferences for both wired and wireless communications is improved.
