Call Content Pre-loading for Caller Credibility Verification

Resolve Bottlenecks,
Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Mobile device users face challenges in identifying and managing unwanted calls, particularly spam or scam calls, as existing tools are limited in providing real-time credibility information about callers, leading to a high percentage of unanswered business calls.

Innovation Solution

A method and system that utilize a content delivery network to pre-load call content on mobile devices, including IP address and user identifier assignment, establishing a secure communication channel, and routing calls with associated content, allowing users to verify caller credibility before answering.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of information

If caller ID or basic data services are used to display caller information, then users can identify some call sources, but users cannot verify caller credibility or distinguish spam/scam calls from legitimate calls

Engineering Contradiction:

Improvecaller credibility informationVSAvoidcall verification system complexity

Core Design Contradiction:

Loss of informationVSDevice complexity

Solution Approach 1:

The system pre-loads call content data (company information, logos, website links, social media profiles) onto mobile devices before calls are received. This preliminary action enables users to verify caller credibility in advance by viewing pre-fetched content, eliminating the need for complex real-time verification during the call.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

A content delivery network acts as an intermediary between calling devices and mobile devices. The CDN stores and delivers call content data to mobile devices, serving as a mediator that provides credibility verification information without requiring direct complex interactions between the calling and called parties.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Reliability

If users manually verify each caller's credibility, then spam calls can be identified, but users lose valuable time and miss legitimate business calls

Engineering Contradiction:

Improvecall identification accuracyVSAvoidcall decision time

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

Call content data is pre-loaded onto mobile devices before calls are received, so credibility information is already available when a call arrives. Users can immediately view company information, logos, and verification data without spending time manually verifying each caller, thus maintaining high reliability while minimizing time loss.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system automatically delivers and stores call content data on mobile devices without requiring user intervention. The mobile device autonomously receives and caches credibility information, enabling users to make informed call decisions instantly without manual verification efforts.

Inventive Principle:

Principle #25Self-service

3Loss of information

If call content data is pre-loaded on mobile devices, then users can verify caller credibility in real-time, but network bandwidth and device storage are consumed

Engineering Contradiction:

Improvecaller verification informationVSAvoidnetwork bandwidth consumption

Core Design Contradiction:

Loss of informationVSQuantity of substance

Solution Approach 1:

Call content data is delivered and stored locally on individual mobile devices based on their specific needs and the calls they are likely to receive. This localized storage approach ensures that each device has the verification information it needs without requiring all devices to store all possible call content, optimizing both bandwidth usage and storage efficiency.

Inventive Principle:

Principle #3Local quality

4Reliability

If a content delivery network is used to pre-load call content, then call credibility verification is enabled, but system complexity increases

Engineering Contradiction:

Improvecaller authenticity verificationVSAvoidcall content management system complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The content delivery network serves as an intermediary that handles the complexity of storing, managing, and delivering call content data. This mediator absorbs the system complexity, allowing the mobile devices and calling devices to remain relatively simple while still enabling comprehensive caller authenticity verification through the CDN's infrastructure.

Inventive Principle:

Principle #24Intermediary (Mediator)

AI summary

One example method of operation may include initiating a call via a calling device to a mobile device via a mobile device telephone number, responsive to initiating the call, retrieving call content data associated with a calling device profile, forwarding the call content data, via a content provider device, to the mobile device prior to establishing the call, hashing the mobile device telephone number to create a hashed value, storing the hashed value in the content provider device, authorizing the mobile device to receive the call content data, receiving a token representing the hashed value from the mobile device via the content delivery device, and connecting the call to the mobile device responsive to the token being authenticated.
