Voice Chat Transmission via SMS Control Channels
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems face challenges in efficiently transmitting voice chat information across different communication standards, particularly in utilizing control channels for carrying voice data in a manner that is compliant with standards, while also managing signaling and media information independently.
Innovation Solution
The system employs a short message service (SMS) gateway coupled with a switching center and an Internet gateway to transmit voice chat information in SMS packets, allowing voice chat sessions between communication stations through a voice chat server, with signaling and media information exchanged independently of the SMS gateway.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If voice chat information is transmitted using traditional traffic channels optimized for voice data, then transmission efficiency is improved, but compatibility with standard-compliant communication devices is worsened because standards define separate control and traffic channels with specific functions
Solution Approach 1:
The patent applies universality by enabling control channels to perform multiple functions - their traditional signaling function plus voice chat data transmission. The control channel is made multi-functional by allowing it to carry both control information and voice chat packets, thereby achieving voice transmission without requiring dedicated voice traffic channels, thus maintaining compatibility with standard-compliant devices while improving transmission efficiency.
Solution Approach 2:
The patent uses an intermediary approach by introducing a packetization mechanism that adapts voice chat data into control channel-compatible formats. The voice chat information is packaged in a manner that allows it to be transmitted through control channels designed for signaling, acting as an intermediary layer that bridges voice data transmission needs with control channel constraints and standards compliance.
2Adaptability or versatility
If control channels are used to carry voice chat data, then compatibility with standard-compliant communication devices is improved, but channel functionality is worsened by mixing control information and voice data in the same channel
Solution Approach 1:
The patent applies segmentation by dividing the control channel transmission into distinct functional segments - control information segments and voice chat data segments. This segmentation allows the receiver to properly separate and process control signaling from voice chat packets, maintaining channel functionality management while enabling dual-purpose usage of the control channel for both control and data transmission.
3Reliability
If separate pathways are maintained for signaling and media information, then system reliability is improved, but network complexity is worsened by requiring multiple independent transmission paths
Solution Approach 1:
The patent applies merging by combining the transmission pathways - signaling and media (voice chat) information are both transmitted through the control channel using the same physical path. This merging reduces network complexity by eliminating the need for separate dedicated pathways while maintaining reliability through proper packetization and channel management that ensures both control and voice data are reliably delivered.
Data Source
AI summary
Systems and methods of exchanging voice chat information are provided. Voice chat information is received and the received voice chat information is placed into one or more packets. A control channel is selected and the one or more packets are transmitted over the selected control channel. The voice chat information can be transmitted in short messaging service (SMS) packets over the control channel. Moreover, voice chat information is exchanged between first and second communication stations by way of a SMS gateway, and media and signaling information are exchanged between the first and second communication stations independent on the SMS gateway.
