Conditional Return Call System with Availability Constraints
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current telecommunications systems lack the ability to allow callers to specify conditions for a return call when they are unable to reach the called user, leading to inefficient message waiting or automatic callback without considering user availability.
Innovation Solution
Implementing an interactive voice response system that prompts callers for availability conditions, such as time and location, and checks if these conditions are met before attempting a return call, allowing for conditional and future-checking of availability across various terminal types.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If automatic callback feature is implemented to call back as soon as user becomes available, then call establishment speed is improved, but user availability control is worsened (no condition specification)
Solution Approach 1:
The system performs preliminary actions by collecting availability conditions from the caller before the called user becomes available. The IVR system prompts the caller to specify conditions (time windows, location constraints, terminal preferences) in advance, and stores these conditions for later evaluation when the called user comes online, enabling both fast callback and user control
2Ease of operation
If message waiting system is used when caller cannot reach called user, then user control over call timing is improved, but call establishment efficiency is worsened (manual intervention required)
Solution Approach 1:
The system implements self-service by automatically evaluating stored availability conditions against the called user's current status and autonomously initiating calls when conditions are met. The system serves itself by monitoring user availability, comparing it with predefined conditions, and executing callback actions without requiring manual intervention from the caller, thus maintaining user control while improving efficiency
3Adaptability or versatility
If conditional availability checking is implemented across multiple terminal types, then adaptability is improved, but system complexity is worsened
Solution Approach 1:
The system achieves universality by implementing a unified availability checking framework that works across diverse terminal types (mobile phones, landlines, VoIP devices, tablets). The IVR system and condition evaluation logic are designed to be terminal-agnostic, handling different communication protocols and device capabilities through a common interface, thereby providing multi-terminal support without proportionally increasing complexity

AI summary
An apparatus and methods are disclosed that enable a caller to specify a condition of availability for a return call when the caller is unable to reach the called user. A condition might indicate a time interval in which the caller is willing to accept a return call, a location, or some other constraints. In the illustrative embodiments, when a caller places a call and is unable to reach the called user, the caller is prompted via an interactive voice response (IVR) system for one or more conditions of availability for a return call. As soon as the called user's terminal becomes available, a software application checks whether the condition of availability is satisfied, and if so, establishes a call between the caller's terminal and the called user's terminal.
