Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Users of communication devices often struggle to prioritize incoming voice calls due to a lack of context, potentially leading to important calls being ignored as they are unaware of the caller's reason for contacting them.

Innovation Solution

A method and device that receive and display text messages during voice calls using Session Initiation Protocol (SIP) sessions, correlating the messages with call correlation information to determine call priority and display them on the communication device during incoming call alerts.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If users receive multiple incoming voice calls without context information, then the volume of communication is maintained, but users cannot prioritize calls and may ignore important ones

Engineering Contradiction:

Improvecall prioritization accuracyVSAvoidcaller context information

Core Design Contradiction:

ReliabilityVSLoss of information

Solution Approach 1:

The patent applies preliminary action by displaying text messages from the caller before the voice call is answered. The system retrieves and displays text message history associated with the caller's number during the incoming call screen, providing context information in advance so users can prioritize calls before answering them.

Inventive Principle:

Principle #10Preliminary action

2Productivity

If users answer all incoming calls immediately, then no important calls are missed, but users waste time on low-priority calls and reduce productivity

Engineering Contradiction:

Improvecall handling efficiencyVSAvoidtime spent on low-priority calls

Core Design Contradiction:

ProductivityVSLoss of time

Solution Approach 1:

The system performs preliminary action by displaying caller context information (text messages) before the call is answered, enabling users to make informed decisions about call prioritization. This allows users to quickly identify and prioritize important calls while potentially skipping low-priority ones, thereby improving call handling efficiency and reducing time wasted on unimportant calls.

Inventive Principle:

Principle #10Preliminary action

3Reliability

If users ignore incoming calls without context, then communication volume is maintained, but important calls may be missed

Engineering Contradiction:

Improveimportant call detectionVSAvoidcall decision making

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The patent implements preliminary action by displaying text message context from callers before the incoming call is answered. This provides users with necessary information in advance to make informed decisions about whether to answer or ignore the call, ensuring important calls are not missed while maintaining ease of operation.

Inventive Principle:

Principle #10Preliminary action

AI summary

A method and device are described for displaying a text message received over a voice call in a communication device. The method includes receiving the text message over an Session Initiation Protocol (SIP) session for the voice call, wherein the text message is received in at least one of an SIP INVITE request and an SIP INFO request. The method includes correlating, by the communication device, the text message with the voice call, based on call correlation information. The method further includes displaying, by the communication device, the text message on the communication device during the SIP session based on the correlation.
