Mobile Terminal Three-Party Video Call via Bluetooth Binding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing videophone technologies on mobile terminals cannot implement three-party calls due to limitations in 3G network bandwidth, leading to poor user experience as the bandwidth consumption increases significantly, and in some cases, three-party calls cannot be established when network bandwidth is insufficient.
Innovation Solution
Implementing a method where an intelligent mobile terminal acts as a server using Bluetooth features to process and transmit audio/video data, allowing a three-party video call by binding server and client terminals via Bluetooth, with data transmission occurring over 3G networks, while the client terminal remains disconnected from the 3G network, using Socket-based Bluetooth techniques for data exchange and processing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If three-party video call is implemented using 3G network, then multi-party communication capability is achieved, but network bandwidth consumption increases excessively causing poor user experience
Solution Approach 1:
The patent divides the network communication into two segments: Bluetooth short-range communication for local terminals and 3G network for remote third-party terminal. This segmentation allows the limited 3G bandwidth to be used efficiently for only the necessary remote communication, while local terminal communication occurs over Bluetooth without consuming 3G bandwidth.
Solution Approach 2:
The patent introduces Bluetooth as an intermediary communication mechanism between mobile terminals. The Bluetooth module acts as a mediator that enables direct peer-to-peer communication between terminals, eliminating the need for all terminals to consume 3G network bandwidth simultaneously for three-party calls.
2Adaptability or versatility
If three-party call is implemented, then conference call functionality is achieved, but existing call is interrupted
Solution Approach 1:
The patent merges multiple call connections into a single integrated three-party call structure. The server terminal combines audio and video streams from multiple clients and integrates them with its own stream, then distributes the merged result to all participants. This merging approach allows third-party joining without interrupting existing calls.
3Reliability
If 3G network channels are allocated to voice communication users, then voice quality is maintained, but video call bandwidth becomes insufficient
Solution Approach 1:
The patent segments the communication protocol usage: Bluetooth for local terminal connections and 3G network for remote third-party communication. This allows voice channels to be allocated to voice users while video data is transmitted efficiently over Bluetooth for local terminals, resolving the bandwidth conflict.
Solution Approach 2:
The patent changes the communication parameter by introducing Bluetooth as an alternative transmission medium. This parameter change allows the system to utilize high-speed Bluetooth connections for local traffic while maintaining 3G voice channel allocations for voice quality, thereby resolving the bandwidth insufficiency problem.
