Telecommunication Device Voicemail Call Setup Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users incur unnecessary charges and inconvenience when calls reach voicemail systems, as they are charged even if they hang up quickly after realizing a voicemail system has answered, leading to a suboptimal user experience.
Innovation Solution
A method in a telecommunication device to determine if a call is likely to reach a voicemail system by receiving a call forwarding notification, allowing for automatic termination of the call setup process before connection, reducing unnecessary call connections and associated costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If the call setup process is allowed to complete normally, then the call may be connected to the called party, but unnecessary charges are incurred when the call reaches voicemail system
Solution Approach 1:
The system performs preliminary detection during call setup to determine if the call will reach voicemail before the connection is fully established. By detecting call forwarding notifications early in the call setup process and terminating the call before connection completion, the system avoids unnecessary charges while maintaining reliable call delivery when needed.
2Loss of energy
If the call setup process is terminated early upon detecting voicemail, then communication costs are reduced, but the user experience deteriorates due to premature termination
Solution Approach 1:
The system uses call forwarding notifications as feedback signals during the call setup process. When such notifications are detected, the system terminates the call setup. This feedback mechanism allows the system to make intelligent decisions about call termination based on network-provided information, balancing cost savings with user experience.
3Loss of time
If the call setup process continues without monitoring, then the system complexity is reduced, but time is wasted listening to greeting messages
Solution Approach 1:
The system performs preliminary monitoring during call setup to detect call forwarding notifications before the call is fully connected. This early detection allows the system to terminate calls that would otherwise connect to voicemail, saving time by avoiding greeting messages while maintaining reasonable system complexity through standardized notification handling.

AI summary
A call setup process (28) in a telecommunication device (10) is controlled, wherein the telecommunication device (10) receives a user command (22) to set up a call, initiates the call setup process (28), determines that the call is likely to reach a voicemail system (14), and, in response to the determination that the call is likely to reach the voicemail system (14), automatically terminates the call setup process (28). A telecommunication device (10) comprises related features. A telecommunication network (12) is adapted to support or implement a determination whether or not an incoming call is forwarded to the voicemail system (14). The invention improves the user experience if a called party does not personally answer a telephone call.
