Call Completion via Messaging Service Transition
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing messaging services do not effectively allow callers to complete call attempts across different networks by providing a seamless messaging service option after call termination due to busy, unreachable, or congested signals, without requiring additional call initiation.
Innovation Solution
A method and system that detects call termination on a first network and communicates the availability of messaging services (SMS, voice SMS, MMS, and multimodal) to the caller, enabling them to create and deliver messages to a second network without re-initiating the call, using voice calls, SMS messages, or USSD alerts, with billing only for message delivery.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a caller manually terminates a call attempt due to busy, unreachable, or congested signals, then the call is ended, but the caller cannot complete communication without re-initiating a new call
Solution Approach 1:
The system performs preliminary action by automatically detecting call termination conditions (busy, unreachable, congested signals) and proactively offering messaging service options to the caller before they manually terminate the call or before they would need to re-initiate a new call attempt. This allows the caller to seamlessly transition from voice call to messaging without time loss.
Solution Approach 2:
The network acts as an intermediary by monitoring call status, detecting termination conditions, and introducing messaging services as a bridge between the failed call attempt and successful communication. The network mediates the transition by presenting messaging options and facilitating the switch without requiring the caller to manually end and restart communication.
2Adaptability or versatility
If messaging service availability is communicated to the caller after manual termination, then the service can be offered, but the caller may have already ended the communication attempt
Solution Approach 1:
The system communicates messaging service availability preliminarily, before the caller manually terminates the call attempt. By detecting termination conditions and offering messaging options in advance, the system ensures the caller is aware of alternative communication methods while the call is still active or just being terminated, thereby maintaining both flexibility and reliability.
Solution Approach 2:
The system implements feedback by continuously monitoring call status and providing real-time information to the caller about messaging service availability. This feedback loop allows the caller to make informed decisions about whether to switch to messaging while the communication context is still fresh, improving both adaptability and reliability.
3Ease of operation
If the network provides call attempt completion services, then communication can be maintained, but the caller may not be informed of the service availability
Solution Approach 1:
The network acts as an intermediary that not only provides the messaging service infrastructure but also actively communicates service availability to the caller. The network mediates between the caller's call attempt and the messaging service, ensuring information about availability is transmitted through the same communication channel.
Solution Approach 2:
The system uses feedback mechanisms to inform the caller about messaging service availability by sending notifications through the existing call interface. This ensures the caller receives information without needing to actively search for or initiate separate service discovery processes.
4Reliability
If the caller re-initiates a call to complete the communication attempt, then communication can be established, but additional billing may occur and time is lost
Solution Approach 1:
The system merges the call completion function with messaging service delivery by detecting call termination and automatically offering messaging as a continuation of the original communication attempt. This consolidation allows the caller to complete communication through a single integrated service rather than separate call and message operations, reducing billing costs and time loss.
Solution Approach 2:
The network performs preliminary detection of call termination conditions and proactively offers messaging service before the caller would need to re-initiate a call. This preliminary action prevents the need for additional call initiation, thereby avoiding associated billing costs and time loss while ensuring communication success.

AI summary
Disclosed herein is a method and system for completing a call attempt made by a first party on a first network to a second party on a second network. The second network may be the first network or one of multiple networks excluding the first network. The first network detects termination of the call attempt. The first network communicates availability of a messaging service to the first party. The messaging service may be a short messaging service (SMS), a voice SMS, a multimedia messaging service, and a multimodal messaging service. The first network does not bill the first party for the communication of the availability of the messaging service. On acceptance of the messaging service by the first party, the first party creates a message to be delivered to the second party on the second network. The first network delivers the message to the second party on the second network.
