Voice Messaging in Mobile Messenger Sessions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional mobile messenger services do not support voice communication during sessions and do not allow person-to-person voice messaging in group chats.
Innovation Solution
A mobile terminal equipped with a microphone, audio storage, and encoding units to capture and encode user voice into audio data packets, which are transmitted over a packet data communication network to other participating terminals using an Enhanced Variable Rate Codec, enabling voice messaging within a mobile messenger service session.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional mobile messenger services use text messages for communication, then the service is simple to operate, but voice communication is not supported during a mobile messenger service session
Solution Approach 1:
The mobile terminal is designed to perform multiple functions within the messenger service: text messaging, voice message recording, encoding, and transmission. The same communication infrastructure handles both text and voice messages, making the system multi-functional without requiring separate systems for each communication type.
Solution Approach 2:
An audio data generation unit is introduced as an intermediary component that converts recorded voice into encoded audio data packets suitable for transmission through the existing messenger service infrastructure. This mediator enables voice communication without directly modifying the core messaging protocol.
2Adaptability or versatility
If conventional mobile messenger services support group chatting, then multiple subscribers can communicate together, but person-to-person messaging is not allowed in a group chatting
Solution Approach 1:
The messaging capability within group chats is made dynamic and flexible. Users can switch between group messaging mode and individual voice messaging mode as needed. The system adapts to different communication needs (group vs. individual) without requiring separate applications or complex configuration changes.
3Adaptability or versatility
If voice messages are transmitted using existing mobile communication systems, then voice communication is supported, but it incurs additional communication costs
Solution Approach 1:
The voice messaging function is merged with the existing data messaging infrastructure. Voice messages are encoded into audio data packets that travel through the same packet data communication network used for text messages and other data transmissions. This consolidation eliminates the need for separate voice communication channels and associated costs.
Solution Approach 2:
Voice messages are converted into digital audio data packets that can be copied and transmitted like any other data. Instead of using traditional voice call protocols, the system creates digital representations of voice that can be sent through the existing data network, leveraging existing infrastructure rather than requiring dedicated voice communication resources.

AI summary
A voice messaging method and a mobile terminal supporting the voice messaging method in a mobile messenger service are provided. The mobile terminal includes a microphone for capturing sound wave and converting the sound wave into an audio signal; an audio storage unit for storing the audio signal; an audio data generation unit for generating audio data packets with the audio signal; a packet data communication network interface unit for providing a packet data communication network; and a control unit for controlling the microphone, audio storage unit, audio data generation unit, and packet data communication network interface unit to capture the audio signal and transmit the audio signal in the form of the audio data packets in response to audio message transmission request entered in the middle of a mobile messenger service session. The voice messaging method includes recording a voice message in response to a voice message transmission request entered in the middle of the mobile messenger service session, generating audio data packets containing the voice message; and transmitting the audio data packets through a packet data communication network in a predetermined period.
