Simultaneous Video and Voice Transmission via Dual Network Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electronic devices cannot simultaneously perform voice calls and image services, requiring separate activation and procedures for image capture and transmission, which is inconvenient for users.
Innovation Solution
An electronic device and method that enable simultaneous image service functionality during voice calls by determining data communication capabilities and quality with a call counterpart, allowing image capture and transmission without additional user control, using a separate communication network for image services.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If image service and voice call are performed separately through the same mobile communication network, then the voice call quality is maintained, but the user cannot simultaneously provide image service during voice call
Solution Approach 1:
The patent divides the communication network into two separate networks: a first communication network for voice calls and a second communication network for image services. This segmentation allows both services to operate independently without interfering with each other, enabling simultaneous provision of both services while maintaining quality of each individual service
Solution Approach 2:
The electronic device is designed to support multiple communication networks and can selectively use different networks for different services. The device universally handles both voice and image services by determining which network to use based on service type, enabling multi-functional operation without requiring separate dedicated devices
2Ease of operation
If separate procedures are required for image capture and transmission, then the voice call function remains simple, but the user convenience deteriorates due to multiple activation steps
Solution Approach 1:
The patent merges the voice call function and image capturing/transmission function into a single integrated system. By establishing a P2P connection that allows both services to operate simultaneously through the same interface, the user can capture and transmit images during an ongoing voice call without leaving the call interface or performing separate activation procedures
Solution Approach 2:
The system performs preliminary actions by pre-establishing the P2P communication connection and determining data communication capabilities before the user needs to transmit an image. When the user activates the camera during a voice call, the image can be immediately captured and transmitted without requiring additional setup or configuration steps
3Reliability
If image service is provided through the same network as voice call, then the network infrastructure remains simple, but the communication stability for image transmission during voice call deteriorates
Solution Approach 1:
The patent segments the communication infrastructure into separate networks for voice and image services. By assigning image services to a second communication network distinct from the first network used for voice calls, the system ensures that image transmission does not compete for bandwidth or resources with voice traffic, thereby maintaining stable communication connections for both services simultaneously
Solution Approach 2:
The system implements feedback mechanisms by determining data communication quality and capabilities before establishing image transmission. The electronic device assesses whether the call counterpart supports data communication and evaluates the quality of the second communication network, using this feedback information to decide whether to proceed with image transmission or switch to alternative schemes
