Caller Route Information Display for Spam Filtering
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The rapid growth of the mobile communication market has led to issues such as personal data thefts, leaks, and an increase in spam calls, which are more bothersome than spam messages or emails due to their requirement for immediate responses, and existing caller identification services often block beneficial calls along with promotional ones.
Innovation Solution
A system and method for providing phone call route information that collects and predicts how a caller obtained a phone number, displaying this information on a called terminal, using network resources, even if the caller's number is untraceable, by comparing calling party and called party information to determine the relation between the selection of a phone number link object and the incoming call, and transmitting this information to the called terminal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If caller identification service blocks all calls from unknown numbers, then spam calls are reduced, but beneficial calls are also blocked
Solution Approach 1:
The patent segments the classification of unknown callers into different categories based on their calling patterns and information sources. Instead of treating all unknown numbers uniformly, the system divides them into segments such as spam callers, legitimate business callers, and personal callers, allowing differential handling of each segment to prevent blocking beneficial calls while still filtering spam.
Solution Approach 2:
The patent introduces an intermediary information display mechanism between the caller ID and the answer decision. This intermediary layer provides route information about how the caller obtained the phone number (e.g., through advertising media, search engines, or direct contact), enabling the called party to make an informed decision about whether to answer without automatically blocking the call.
2Reliability
If all incoming calls from non-contact numbers are blocked, then personal information security is improved, but legitimate business opportunities are lost
Solution Approach 1:
The patent performs preliminary actions by collecting and analyzing calling route information before the final answer decision is made. The system pre-gathers data about how the caller obtained the phone number, what advertising media they encountered, and their calling patterns, preparing this information in advance to enable quick assessment of call legitimacy without compromising security.
Solution Approach 2:
The patent implements feedback mechanisms where the system continuously learns from user responses to displayed route information. By analyzing whether users answer or block calls based on the displayed route information, the system refines its classification algorithms and improves future predictions, thereby enhancing both security and opportunity capture over time.
3Measurement precision
If caller route information is collected and analyzed, then call legitimacy is determined, but system complexity increases
Solution Approach 1:
The patent applies multi-functionality by designing the calling terminal and server to perform multiple functions: collecting calling information, analyzing route data, classifying callers, and providing recommendations all within a single integrated system. This universal approach reduces the need for separate specialized systems and manages complexity through consolidation of functions.
4Loss of information
If phone number link object selection is tracked, then advertising effectiveness is measured, but user privacy concerns increase
Solution Approach 1:
The patent applies local quality by selectively collecting different types of information based on the context and user preferences. Instead of uniformly tracking all user actions, the system collects route information locally at specific points (such as when a phone number link is selected from advertising media) and only retains data necessary for determining call legitimacy, minimizing privacy intrusion while maintaining measurement capability.

AI summary
Provided is a system, apparatus, and/or method for providing phone call route information, including a calling party information collector configured to collect calling party information according to selecting of a phone number link object provided to a calling party through a network a called party information collector configured to collect called party information about a certain incoming call from a called terminal, and a matching determiner configured to determine a relation between the selecting of the phone number link object and the certain incoming call by comparing at least one piece of the calling party information and at least one piece of the called party information.
