Mobile Terminal Blocking Program for Malicious Call Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mobile phone users face financial loss and harassment due to malicious calls from automatic or manual equipment, which existing technologies fail to effectively block, as third-party software lacks the authority to control the mobile terminal's calling process.
Innovation Solution
A method and system that inject a blocking program into the mobile terminal to acquire root privilege, allowing it to delay or block incoming calls from predefined malicious numbers by determining if the incoming phone number matches a preset rule, thereby preventing single ring harassing calls.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If third-party software is used to block malicious calls, then user protection against harassment is improved, but the software cannot acquire system authority to control the calling process
Solution Approach 1:
The blocking program is pre-injected into the mobile terminal system before malicious calls occur. This preliminary action allows the program to acquire root privilege and integrate into the system's calling process control, enabling it to intercept and block malicious calls effectively without needing to request authority during operation.
Solution Approach 2:
The blocking program acts as an intermediary between the mobile terminal system and the calling process. It acquires root privilege to position itself as a mediator that can monitor incoming calls, identify malicious numbers, and control the calling process by delaying or blocking rings, thus protecting users without requiring direct system authority changes.
2Object-affected harmful factors
If the blocking program delays rings for predefined numbers, then malicious call harassment is reduced, but legitimate calls may be delayed
Solution Approach 1:
The blocking program applies preliminary anti-action by pre-defining a list of malicious phone numbers and patterns before calls occur. When a call comes from a predefined malicious number, the program immediately delays the ring, preventing the user from being harassed. The delay time is controlled to be sufficient to block single-ring harassment but not so long as to permanently block legitimate calls.
Solution Approach 2:
The blocking program dynamically adjusts its behavior based on the incoming call characteristics. It delays rings for calls from predefined malicious numbers but allows normal ring behavior for other numbers. The program can also adapt the delay duration and blocking decision based on call patterns, ensuring legitimate calls are not permanently affected while malicious calls are effectively blocked.

AI summary
Disclosed are method, device and system for processing a calling requires message of a mobile terminal, the method comprising: triggering a pre-embedded blocking program in the calling process; upon detecting a calling request message, the blocking program acquires an incoming call number in the calling request message; the blocking program determines whether the incoming call number is a call number defined by a preset rule, if the incoming call number is a call number defined by the preset rule, then delaying the ring of the phone number defined by the preset rule. The present invention protects a user from the harassment of a malicious harassing call, thus avoiding unnecessary financial loss.
