Falsified Call Identification via Intermediary Verification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for identifying falsified-number incoming telephone calls are prone to errors and limitations, particularly when dealing with calls from abroad or using Voice Over Internet Protocol (VOIP), as they rely on number coding rules that can lead to incorrect determinations.
Innovation Solution
A method and device that determine whether a telephone call is falsified by verifying the authenticity of the calling party's telephone number through an assigned entity affiliated with the calling party, independent of number coding rules, by checking if the second telephone apparatus of the assigned entity is the authentic source of the call, and providing a prompt to the called party when a falsified call is detected.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the method for identifying falsified-number incoming telephone call by controlling a prefix is used, then the identification process is simple, but the determination accuracy deteriorates due to mistakes and limitations
Solution Approach 1:
The patent introduces an intermediary verification mechanism by checking whether the called party's terminal is currently in a calling state to the calling party's number. This intermediary check acts as a mediator between the simple prefix control method and accurate falsified call identification, resolving the contradiction by maintaining operational simplicity while significantly improving determination accuracy through an additional verification layer.
2Ease of manufacture
If the prefix control method is used to identify falsified calls, then the implementation is straightforward, but the method has limitations and cannot determine calls conforming to Chinese mainland number rules
Solution Approach 1:
The patent applies universality by designing a verification method that works across different telephone number formats and regions. The core verification logic (checking if the terminal is in a calling state) is universally applicable regardless of whether the call uses prefix patterns or conforms to Chinese mainland number rules, thereby enhancing the method's adaptability and versatility while maintaining implementation straightforwardness.
3Productivity
If the prefix control method is used, then the identification process is quick, but the reliability deteriorates as it may make mistakes in determining authentic versus deceptive calls
Solution Approach 1:
The patent implements feedback by using the real-time calling state information of the terminal as verification feedback. The system checks whether the terminal is currently in a calling state to the calling party's number, and uses this feedback to confirm or refute the authenticity of the incoming call. This feedback mechanism maintains quick identification speed while significantly improving reliability by providing objective evidence to distinguish authentic from deceptive calls.

AI summary
A method and a device for identifying a telephone call are provided. The method includes: determining (101) whether a second telephone apparatus of an assigned entity, said entity being affiliated with a telephone number of a telephone calling party, is calling a telephone number of a first telephone apparatus, when the telephone calling party is calling the telephone number of the first telephone apparatus, wherein the telephone number of the second telephone apparatus is the telephone number of the telephone calling party; when the second telephone apparatus is not calling the telephone number of the first telephone apparatus, outputting (102) prompt information, wherein the prompt information is for indicating that the telephone call from the telephone calling party is a falsified-number telephone call. The present invention may correctly identify whether a telephone call is a falsified-number telephone call.
