Remote Management Messenger System Call Screening via Answering-and-Recording Function

Resolve Bottlenecks,
Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Packet switching technologies, such as VoIP, lack call screening capabilities, making it difficult for users to manage and control incoming calls effectively, especially when they do not respond to calls within a predetermined time, leading to potential loss of messages and lack of privacy control.

Innovation Solution

A remote management messenger system (RMMS) that activates an answering-and-recording function if the receiver does not respond to a call within a predetermined time, allowing the system to receive and record packets, play pre-recorded messages, and enable call screening, while maintaining a virtual connection for the receiver to interrupt and respond later.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If packet switching technology is used for telecommunication, then resource utilization and cost efficiency are improved, but call screening capability is lost

Engineering Contradiction:

Improveresource utilizationVSAvoidcall screening capability

Core Design Contradiction:

ProductivityVSEase of operation

Solution Approach 1:

The patent introduces an intermediary component (answering machine system) that bridges the gap between packet switching technology and call screening functionality. The system captures call packets, processes them through an answering machine interface, and enables call screening without requiring changes to the underlying packet switching network infrastructure.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent segments the call handling process into distinct functional components: packet reception, call screening logic, message recording, and user notification. This segmentation allows call screening to be implemented as a separate layer on top of packet switching, maintaining the efficiency of the base technology while adding the desired functionality.

Inventive Principle:

Principle #1Segmentation

2Ease of operation

If answering machine records all incoming calls, then call screening is improved, but memory space is consumed

Engineering Contradiction:

Improvecall screeningVSAvoidmemory space

Core Design Contradiction:

Ease of operationVSQuantity of substance

Solution Approach 1:

The patent applies local quality by recording only specific calls that meet certain criteria (e.g., calls that are screened, calls from unknown numbers, or calls marked for recording). Instead of uniformly recording all calls, the system selectively records based on local conditions and user preferences, thereby conserving memory space while maintaining effective call screening.

Inventive Principle:

Principle #3Local quality

3Object-affected harmful factors

If receiver personally answers each call to verify validity, then privacy control is improved, but time consumption increases

Engineering Contradiction:

Improveprivacy controlVSAvoidtime consumption

Core Design Contradiction:

Object-affected harmful factorsVSLoss of time

Solution Approach 1:

The patent implements preliminary action by enabling the answering machine to perform call screening and validation before the receiver needs to personally intervene. The system pre-processes incoming calls, identifies valid versus invalid calls, and prepares information for the receiver in advance, allowing the receiver to make informed decisions about which calls to answer without spending time on each individual call verification.

Inventive Principle:

Principle #10Preliminary action

4Ease of operation

If answering machine is used with circuit switching, then call screening is enabled, but resource efficiency deteriorates

Engineering Contradiction:

Improvecall screeningVSAvoidresource efficiency

Core Design Contradiction:

Ease of operationVSProductivity

Solution Approach 1:

The patent substitutes the traditional circuit switching mechanism with a packet switching-based system. Instead of maintaining dedicated circuit connections for call screening functionality, the system uses packet-based communication to achieve the same call screening effects, thereby improving resource efficiency while maintaining the desired functionality.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

AI summary

In a remote management messenger system (RMMS), a method for screening a packet-based call originated from a caller via a caller telecommunication device (CTD) to a receiver telecommunication device (RTD) via the RMMS. The method includes activating, if a receiver associated with the RTD does not respond to the packet-based call within a predetermined time period, an answering-and-recording function (ARF) associated with the RMMS to enable the ARF to receive and record packets pertaining to the packet-based call while permitting the receiver to continue to hear the caller. The method also includes, if the receiver responds to the packet-based call after the ARF is activated, permitting the receiver to continue the packet-based call with the caller.
