Callback Notification System for Prepaid Credit Constraints
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users with prepaid accounts for telecommunication services often face difficulties in communicating due to insufficient credit, especially when they lack access to recharge their accounts, and existing systems fail to automatically detect unsuccessful communication attempts and send callback notifications without user initiation.
Innovation Solution
A callback notification system that uses a processor to send missed call ring alerts or alternative notifications, such as SMS messages, to a called party's device when a calling party's account lacks sufficient credit or network connectivity, ensuring the call is not chargeable and providing options for communication, like emergency credit features.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a calling party uses a prepaid account with insufficient credit, then communication services cannot be accessed, but the user still needs to communicate for urgent needs
Solution Approach 1:
The system performs preliminary detection of insufficient credit status before allowing communication attempts, and pre-provides callback notification as a solution. The network detects the credit status in advance and automatically sends notifications to the called party, enabling communication without requiring the user to manually initiate multiple actions or have sufficient credit upfront.
2Productivity
If the system sends automatic callback notifications, then communication opportunities are preserved, but system complexity increases
Solution Approach 1:
The network system automatically detects insufficient credit status and self-initiates the callback notification process without requiring user intervention. The system monitors credit balances, identifies when communication attempts would fail, and automatically sends notifications to the called party, making the complex process transparent to the end user.
Solution Approach 2:
The system implements feedback loops where the network continuously monitors credit status and communication attempt outcomes. When a failure is detected due to insufficient credit, the system responds by sending callback notifications, creating a closed-loop control system that adapts to user needs based on real-time status information.
3Ease of operation
If missed call detection is implemented, then free communication attempts are enabled, but detection accuracy challenges arise
Solution Approach 1:
The network system acts as an intermediary between the calling and called parties, detecting communication failures and mediating the callback notification process. The network monitors call setup phases, identifies when calls fail due to insufficient credit, and sends notifications through intermediate channels such as SMS or data messages, ensuring accurate detection and appropriate response.
Data Source
AI summary
A method and a callback notification system (CNS) are provided for sending a missed call ring alert (MCRA) from a source number to a destination number. The CNS receives communication information from a calling party device (CGPD) or a network thereof, when an unsuccessful communication attempt is made by the CGPD to contact a called party device (CDPD), and places a call to the destination number with an identification of an originator of the call as the source number using the communication information. The CNS identifies a ring of the CDPD when the call successfully reaches the destination number and terminates the call before chargeable completion of the call, thereby sending an MCRA from the source number of the CGPD to the destination number of the CDPD. The CNS sends one or more alternative callback notifications to the destination number, concurrently with the MCRA or if the MCRA is unsuccessful.
