Controlled Cellular Network Security for Mobile Device Privacy
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current security solutions for cellular networks are limited in addressing threats to user cellular devices (UCDs) from both the device and network perspectives, failing to provide comprehensive security and privacy protection against various cyber attacks and data breaches.
Innovation Solution
A Controlled Cellular Network (CCN) system that integrates multiple modules, including a Security Center module, Probe Interface module, Data Analysis module, and Security Action Management module, to monitor, analyze, and manage communication interactions between UCDs and the cellular network, applying real-time security measures and identity mediation to ensure privacy and security.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional security tools (anti-malware software) are installed on UCDs to provide security monitoring, then some degree of security is achieved, but the solution is limited in scope and requires external updates and installation
Solution Approach 1:
The patent introduces a network-based security intermediary system that mediates between UCDs and potential threats. Instead of relying solely on endpoint security software, the system deploys monitoring and control functionality within the cellular network infrastructure itself, acting as an intermediary layer that can detect and respond to threats without requiring complex user-side security tools
Solution Approach 2:
The patent replaces the mechanical approach of installing and updating security software on each device with a network-based system that provides security services through the cellular infrastructure. This substitution eliminates the need for manual software installation and updates on user devices, centralizing security management in the network domain
2Reliability
If network security solutions are implemented to secure cellular network modules, then network functionality is protected, but UCD data security and subscriber privacy are not directly addressed
Solution Approach 1:
The patent segments security functionality into distinct network-based modules: a security policy management component that handles privacy and data protection policies, and a network monitoring component that detects threats. This segmentation allows the system to address both network module security and subscriber data privacy through specialized, coordinated functions rather than a monolithic approach
Solution Approach 2:
The patent implements feedback mechanisms where the network monitoring system continuously observes UCD communications and network traffic, detects potential threats to subscriber data, and triggers automated responses. The system provides real-time feedback loops that enable dynamic adjustment of security measures to protect subscriber privacy while maintaining network functionality
3Reliability
If comprehensive security monitoring is implemented at the network level, then subscriber privacy and data security are enhanced, but system complexity and resource requirements increase
Solution Approach 1:
The patent creates a universal network-based security system that serves multiple functions: monitoring network traffic for threats, enforcing security policies, protecting subscriber privacy, and securing UCD data. By consolidating these diverse security functions into a single network platform, the system reduces overall complexity compared to implementing separate specialized systems for each security concern

AI summary
The present invention discloses a system and a method for securing the privacy of cellular network subscribers and the security of data stored on the said subscribers' User Cellular Devices (UCDs) The system comprises a Controlled Cellular Network (CCN), interfacing a cellular Public Land Mobile Network (PLMN), hosting a plurality of cellular subscribers. The said CCN system provides said security services to "serviced subscribers" of the hosting PLMN. The CCN encapsulates communication between UCDs of serviced subscribers and the hosting PLMN, including at least part of: control, signaling, SMS and data communications. The CCN is configured to identify security threats to the privacy of serviced subscribers and to the data stored on their UCDs, and determine said threats' category and probability, based on analysis of said encapsulated communication. CCN is configured to respond to said threats in real or near-real time, and take active measures to avert said suspected threats.
