Solution Overview

Problem

Existing solutions for call disconnections in telecommunications do not adequately inform the second party about the status of the call or provide options for the first party to reconnect, leading to premature hang-ups and missed opportunities for reconnection.

Innovation Solution

A method utilizing a call management node that intercepts disconnection messages and connects the second party to a service node, providing vocal or other services to inform them of the disconnection and allowing the first party to potentially rejoin the call, with features like music or voicemail options.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the call management node maintains the call temporarily for the first party to reconnect, then the first party has a window of time to reconnect to the call, but the second party has no indication of what is happening with the call and may hang up prematurely

Engineering Contradiction:
Improvecall reconnection success rateVSAvoidcall status information for second party
Core Design Contradiction:
ReliabilityVSLoss of information

Solution Approach 1:

The system implements feedback by notifying the second party when the first party reconnects to the call. The call management node sends a notification message to the second party's device indicating that the first party has been reconnected, providing real-time status information that prevents premature hang-ups and maintains call integrity throughout the reconnection process.

Inventive Principle:
Principle #23Feedback

2Loss of information

If the call management node provides notification services to the second party, then the second party is informed of call status, but the system complexity increases with additional notification mechanisms

Engineering Contradiction:
Improvecall status information deliveryVSAvoidcall management system complexity
Core Design Contradiction:
Loss of informationVSDevice complexity

Solution Approach 1:

The call management node performs multiple functions: it maintains the call connection for the first party during disconnection, monitors reconnection status, and sends notifications to the second party. By consolidating these diverse functions into a single node, the system avoids the complexity of separate dedicated components for each function while achieving comprehensive call status management and notification capabilities.

Inventive Principle:
Principle #6Universality (Multi-functionality)

AI summary

The invention relates to a method, in a telecommunication network, for alerting at least a second party in a call with a first party that said first party experienced a call disconnection, said telecommunication network comprising a call management node adapted to receive signaling information of any call disconnection of either parties, a service node for providing a communication service to either one of the first and second parties, said method comprising for said call management node the acts of intercepting the signaling information corresponding to the call disconnection of the first party, sending a connection update so that the second party becomes connected to the service node for provision of the communication service, wherein the signaling information comprises an indication of the cause of the call disconnection, and wherein the call management node is further adapted to withhold the connection update if said cause that does not require the provision of the one or more communication service(s) to the second party.
