Call Termination Module for Wireless Network Charge Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current communication systems incur unnecessary charges for mobile users when calls are not answered or terminated, as they establish connections through wireless networks, leading to additional billing for voice messaging services.
Innovation Solution
A method and system that includes a call termination module in a mobile station to determine if it is in call termination mode and communicate a communication protocol to a switching module to terminate the call, using ISDN User Part (ISUP) protocol, allowing users to opt out of calls and send messages to the calling device after termination, with features like haptic gestures and alphanumeric codes for termination.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the mobile station answers the call or allows voice messaging service to establish connection, then the calling party can communicate with the mobile station, but the mobile user incurs additional charges for wireless network usage
Solution Approach 1:
The system performs preliminary action by detecting incoming call status and automatically terminating the call before the user answers or before voice messaging service establishes connection. The call termination module monitors call state and executes termination proactively, preventing the mobile station from incurring network charges while maintaining the ability to communicate through alternative means (SMS message delivery).
Solution Approach 2:
The invention extracts the harmful element (unnecessary network connection) from the system by selectively terminating calls that would result in charges. The call termination module identifies and removes the problematic connection while preserving the essential communication function through message delivery, thus separating the harmful network usage from the useful communication objective.
2Loss of energy
If the call is terminated automatically, then the mobile user avoids unnecessary charges, but the calling party may not be aware that the call was terminated and expect a message
Solution Approach 1:
The system implements feedback by automatically sending an SMS message to the calling party after terminating the call. This feedback mechanism informs the caller that the call was terminated and provides context (that a message will be delivered), preventing confusion and maintaining communication transparency. The message serves as confirmation that the termination was intentional and systematic.
Solution Approach 2:
The invention introduces an intermediary element (SMS message) that bridges the gap between call termination and user notification. Instead of directly notifying the caller through the terminated voice channel, the system uses a different communication medium (text messaging) to convey termination information, ensuring the caller is informed without requiring the original call connection to remain active.
3Ease of operation
If the mobile station provides call termination functionality, then users gain control over call management, but the device complexity increases with additional modules and protocols
Solution Approach 1:
The call termination module leverages existing multi-functional capabilities of the mobile station, utilizing the same communication protocols and message delivery infrastructure already present in modern smartphones. By repurposing existing components (message module, communication interface, protocol stack) for call termination functionality, the system avoids significant complexity increases while providing enhanced user control.
Solution Approach 2:
The invention merges the call termination function with the existing message delivery system. The same message module that handles outgoing SMS messages is also used to send termination notifications to callers. This consolidation integrates multiple functions (call monitoring, call termination, message sending) into existing system components, minimizing the addition of separate complex subsystems.

AI summary
A method, apparatus, and system of using call termination to communicate a message are disclosed. In one embodiment, a system of a telecommunications network includes a mobile station associated with the telecommunications network, a switching module of the telecommunications network to establish a call between a communication device and the mobile station, a call termination module of the mobile station to determine if the mobile station is in a call termination mode and to communicate a communication protocol to the switching module to cause the switching module to terminate the call if the mobile station is in the call termination mode, and a message module of the telecommunications network to communicate a message to the communication device.
