Outgoing Call Channel Information Extraction for Spam Filtering
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The increasing prevalence of mobile communication devices has led to personal information leakage and a rise in spam calls, making it difficult for users to distinguish between desired and unwanted calls, while advertisers face challenges in determining the effectiveness of advertising media through which consumers contact them.
Innovation Solution
A system and method that provide outgoing call channel information by extracting and parsing source codes from call connection request signals to identify the source of the caller's phone number, allowing called parties to display this information, thereby enabling users to determine the legitimacy and origin of incoming calls and advertisers to evaluate advertising media effectiveness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a caller identification service is used to block calls from non-registered calling parties, then spam calls are reduced, but desired calls or other like calls are also blocked
Solution Approach 1:
The patent segments the blocking decision by introducing multiple dimensions of information (caller ID, outgoing call channel, advertising medium) rather than relying solely on contact list registration. This allows for nuanced filtering where calls can be evaluated based on multiple criteria, enabling users to distinguish between spam and desired calls more accurately.
Solution Approach 2:
The system implements feedback mechanisms where called parties can provide responses about incoming calls (spam or desired), and this feedback is used to improve future call routing and filtering decisions. The system also provides feedback to advertisers about which advertising media are effective, creating a closed-loop learning system.
2Quantity of substance
If advertisers use multiple advertising media to promote products, then advertising reach is increased, but ability to determine effectiveness of particular advertising media is reduced
Solution Approach 1:
The system captures feedback from called parties about the source of the call (which advertising medium they encountered the phone number in). This feedback is transmitted back to advertisers, allowing them to evaluate which advertising media are most effective at generating actual calls, thus resolving the information loss problem.
Solution Approach 2:
The outgoing call channel information serving mechanism is designed to serve multiple functions: it helps called parties identify call sources, provides advertisers with effectiveness data, and enables network operators to optimize routing. This multi-functional approach maximizes the value extracted from the same data collection mechanism.
3Reliability
If caller identification information is provided to called parties, then call legitimacy is improved, but call information completeness is reduced without outgoing call channel information
Solution Approach 1:
The patent merges multiple information elements (caller ID, outgoing call channel, advertising medium information) into a comprehensive call information package transmitted to called parties. This combination provides both legitimacy verification through caller ID and origin context through channel information, resolving the information completeness issue.
Data Source
AI summary
An outgoing call information providing device includes a non-transitory computer-readable medium configured to store program code and a processor configured to execute the program code to receive a call connection request signal from a caller party terminal, the call connection request includes (i) a phone number of a called party terminal and (ii) a source code indicating a source from which the caller party terminal obtained the phone number of the called party terminal; extract the source code from the call connection request signal; parse the extracted source code; generate outgoing call channel information based on the parsed source code, the outgoing call channel information indicating the source; and transmit the call connection request signal according to the phone number of the called party terminal such that the called party terminal receives the generated outgoing call channel information with a phone number of the caller party terminal.
