Telecommunications Link Separate Data Channel for Display Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for operating telecommunications links between answering devices and terminals are not user-friendly, as they require IP addresses for data transmission and can disrupt voice channels with additional data, limiting the ability to transmit display control commands effectively.
Innovation Solution
A method that establishes a voice and data channel connection, allowing display control commands to be transmitted separately from voice information, enabling automatic responses and screen content requests without affecting voice transmission, using protocols like WML or HTML, and allowing URL information for navigating screen pages.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If display control commands are transmitted in the voice channel along with voice information, then data transmission is achieved, but the voice transmission quality is degraded and the available audio bandwidth is reduced
Solution Approach 1:
The patent segments the communication channel into separate voice channel and data channel. Display control commands are transmitted exclusively in the data channel while voice information is transmitted in the voice channel, eliminating mutual interference and preserving voice quality while enabling data transmission.
2Loss of information
If IP addresses are required for establishing data links between telecommunications devices, then data transmission can be established, but the system complexity increases and user-friendliness decreases
Solution Approach 1:
The patent implements automatic IP address assignment through DHCP protocol, allowing telecommunications devices to obtain IP addresses automatically without manual configuration. This eliminates the need for users to manually manage IP addresses while maintaining data link establishment capability.
3Productivity
If the same channel is used for both voice and data transmission, then channel utilization is maximized, but the functionality for separate optimized transmission is lost
Solution Approach 1:
The patent divides the communication infrastructure into separate voice channels and data channels. This segmentation allows each channel to be optimized for its specific type of traffic - voice channels optimized for audio transmission and data channels optimized for control commands and information transfer.
Solution Approach 2:
The patent creates a multi-functional communication system where the telecommunications link simultaneously supports voice transmission, data transmission, and display control command transmission through different channels, providing versatile functionality while maintaining channel optimization.
Data Source
AI summary
A method for operating a communications link between two telecommunications device requires that speech information be transmitted in a speech channel and data signals are transmitted in a data channel that is separate from the speech channel. This provides a particularly user-friendly, convenient method for operating a telecommunications link. To achieve this, display control commands are transmitted in the data channel as data signals, the display control commands triggering a display on a screen of the telecommunications device that receives the display control commands.
