Automated Call Set-Up via Terminal Command Trigger
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing solutions for automated call set-up between terminals are resource-intensive for server bandwidth and not compatible with circuit-switched networks like GSM mobile networks, leading to billing issues and inefficiencies.
Innovation Solution
A method where a processing server sends a command message to a first terminal to initiate a call request directly, allowing user validation and billing accuracy, utilizing existing network infrastructures for message routing and control, specifically using SMS messages in GSM networks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If a server generates and sends call set-up requests between terminals, then automated call set-up is achieved, but server bandwidth resources are excessively consumed
Solution Approach 1:
The patent extracts the call set-up request generation function from the server and transfers it to the terminal devices. The server only sends command messages to trigger the terminals to autonomously generate and send call set-up requests, thereby eliminating the need for the server to directly establish communication links and reducing server bandwidth consumption.
Solution Approach 2:
The terminal devices are empowered to autonomously generate and send call set-up requests without requiring the server to directly establish connections. The terminals self-manage the call set-up process by receiving simple trigger commands from the server and independently completing the connection establishment, making the system self-serving and reducing server resource burden.
2Adaptability or versatility
If a server establishes communication links between terminals, then call set-up is achieved, but the solution is not compatible with circuit-switched networks like GSM
Solution Approach 1:
The patent segments the call set-up process into two independent parts: (1) the server sends command messages through existing message routing infrastructure, and (2) the terminal autonomously generates and sends call set-up requests. This segmentation allows the solution to work with different network types (packet-switched and circuit-switched) by using appropriate message routing for each, thereby improving network compatibility without increasing overall system complexity.
Solution Approach 2:
The server uses a universal command message sending mechanism that can operate across different network types. By sending standardized command messages that terminals can interpret and act upon regardless of the underlying network architecture (GSM, IP-based, etc.), the solution achieves multi-functionality and broad network compatibility without requiring network-specific connection establishment logic.
3Extent of automation
If the server initiates call set-up, then automated connection is achieved, but billing accuracy is compromised in circuit-switched networks
Solution Approach 1:
The terminal performs preliminary action by autonomously generating and sending the call set-up request before the actual call connection is established. This preliminary action ensures that the network recognizes the terminal as the calling party from the outset, enabling accurate billing identification. The server's role is limited to sending a trigger command that initiates this preliminary action, maintaining automation while ensuring billing accuracy.
