Solution Overview

Problem

Current smartphone systems are inconvenient for exchanging contact information beyond phone numbers, requiring manual input and lacking assurance of accuracy and completeness.

Innovation Solution

A VoLTE-based voice communication method and system that embeds business card information into calling requests, allowing users to easily share and store contact details during calls using INVITE packets with SDP content.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If manual input method is used to exchange contact information, then users can obtain contact information, but the process is inconvenient and accuracy cannot be assured

Engineering Contradiction:

Improveconvenience of contact information exchangeVSAvoidaccuracy of contact information

Core Design Contradiction:

Ease of operationVSMeasurement precision

Solution Approach 1:

The business card information is prepared and embedded in the calling request packet in advance. When the calling party initiates a call, the contact information (name, company, title, fax number, email address, etc.) is automatically included in the INVITE packet with SDP content, eliminating the need for manual input by the receiving party and ensuring accuracy from the source.

Inventive Principle:

Principle #10Preliminary action

2Productivity

If manual input method is used to add contact information to address book, then contact information can be stored, but the process is time-consuming and labor-intensive

Engineering Contradiction:

Improveefficiency of contact information storageVSAvoidtime required for manual input

Core Design Contradiction:

ProductivityVSLoss of time

Solution Approach 1:

The system enables automatic extraction and storage of business card information from the calling request packet. When the called terminal receives the INVITE packet containing SDP content with business card information, the information is automatically parsed and stored in the address book without requiring manual typing or copying by the user, significantly improving efficiency and reducing time loss.

Inventive Principle:

Principle #25Self-service

3Adaptability or versatility

If traditional calling request format is used, then voice communication can be established, but business card information cannot be transmitted

Engineering Contradiction:

Improvefunctionality of calling requestVSAvoidbusiness card information transmission

Core Design Contradiction:

Adaptability or versatilityVSLoss of information

Solution Approach 1:

The patent merges the voice call initiation function with business card information transmission by embedding the business card information within the SDP content of the INVITE packet. This combining allows a single communication packet to simultaneously establish voice communication and transmit contact information, eliminating the need for separate information exchange processes.

Inventive Principle:

Principle #5Merging (Combining)

AI summary

Disclosed in the present invention is a VoLTE-based voice call method. The method comprises: a calling terminal determining whether a VoLTE call mode is activated: if so, the calling terminal generating a call request, the call request comprising contact card information of the calling terminal; and the calling terminal sending the call request to the called terminal, so as to enable the called terminal to acquire the contact card information of the calling terminal from the call request. The present invention can facilitate users to exchange contact card information.
