Call Processing Method for Unknown Caller Identification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current call processing systems struggle to effectively handle unknown callers, leading to rejection of both harassment and non-harassment calls, as they rely on caller identification, which is limited for unknown numbers.
Innovation Solution
A call processing method that sends prompt information, such as text, image, audio, or video, to the callee during the calling process to identify the caller's identity and purpose, allowing the callee to decide whether to answer, and includes a reattempt call service that initiates prompt information when an initial call is rejected or unanswered.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If subscribers reject all phone calls from unknown callers to prevent harassment, then harassment calls are blocked, but non-harassment calls from unknown callers are also rejected
Solution Approach 1:
The system performs preliminary actions by sending prompt information (text, image, audio, or video) to the callee before the actual call connection is established. This allows the callee to identify the caller's identity and purpose in advance, making an informed decision about whether to answer the call, thereby preventing both harassment and legitimate calls from being rejected.
Solution Approach 2:
The patent introduces an intermediary mechanism (prompt information transmission system) between the caller and callee. This intermediary provides additional information about the caller's identity and purpose, enabling the callee to make better judgment calls without simply blocking all unknown numbers, thus resolving the contradiction between blocking harassment and maintaining call success rate.
2Loss of information
If caller identification services are used to identify unknown callers, then some harassment calls can be blocked, but the service is limited and cannot effectively identify all unknown callers
Solution Approach 1:
The patent applies universality by using multiple types of prompt information (text, image, audio, and video) to identify callers, rather than relying on a single caller identification method. This multi-functional approach enables effective identification across various scenarios, including unknown callers, enhancing both the effectiveness and application scope of the anti-harassment service.
Solution Approach 2:
The system sends prompt information containing caller identity and purpose details before the call is answered. This preliminary provision of comprehensive information allows the callee to identify unknown callers effectively, overcoming the limitations of traditional caller identification services that cannot handle all unknown caller scenarios.
3Ease of operation
If traditional call blocking methods are used, then harassment prevention is simplified, but the ability to distinguish between harassment and non-harassment unknown calls is lost
Solution Approach 1:
The system implements feedback by providing the callee with prompt information about the caller's identity and purpose before the call connection is established. This feedback mechanism enables precise identification of whether an unknown call is harassment or legitimate, while maintaining ease of operation as the callee simply needs to view the information and decide whether to answer, without complex manual blocking operations.
