Real-Time Duplication Server for Lawful Call Interception
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current communication networks, especially upcoming 5G networks, lack a mechanism for legal enforcement agencies to access real-time call information and additional interactive data such as context information during calls, which is essential for building cases and monitoring communications.
Innovation Solution
A method and system that involves a real-time duplication server (RTDS) to receive and convert context information specified by a user into a visual representation, allowing lawful enforcement agencies to intercept and communicate this information to target terminals before an audio/visual call is established, enabling real-time monitoring and modification of call data.

Engineering Contradiction Analysis
1Loss of information
If real-time interception of call information is implemented, then law enforcement agencies can access communication data for building cases, but no mechanism exists to access additional interactive data such as context information in 5G networks
Solution Approach 1:
The Real-Time Duplication System (RTDS) is designed to handle multiple types of communication data including traditional voice calls, video calls, and 5G interactive data through a single unified mechanism. The system can intercept and duplicate various data types (call information, context information, sketch sharing, chatting data) using the same infrastructure, making it universally applicable across different network generations and communication modes.
Solution Approach 2:
The system establishes duplication rules in advance that define what information should be intercepted and how it should be routed. These rules are configured beforehand to capture not only traditional call data but also future 5G interactive data types, allowing the system to be proactive rather than reactive when new data types emerge.
2Ease of operation
If context information is converted into visual representation and communicated to users, then real-time monitoring capability is enhanced, but system complexity increases
Solution Approach 1:
The RTDS acts as an intermediary component between the network infrastructure and law enforcement monitoring systems. It converts raw intercepted data into standardized visual representations that are easier to analyze, while maintaining a clear separation between the complex interception mechanism and the simplified monitoring interface. This mediator role reduces the complexity burden on both ends of the system.
Solution Approach 2:
The system creates visual copies or representations of the intercepted context information rather than requiring direct analysis of raw data streams. These visual representations (such as structured displays of call metadata, participant information, and interaction patterns) simplify the monitoring process while preserving all essential information for investigative purposes.

AI summary
A method for accessing call information communicated between a source terminal and a target terminal over a carrier network is provided. The method includes receiving, at a real-time duplication server (RTDS), context information specified by a user of the source terminal that defines information to be communicated to the target terminal prior to establishment of an audio/visual call between the source terminal and target terminal. The method also includes converting, by the RTDS, the context information into a visual representation of the context information; and communicating, by the RTDS, the visual representation of the context information to a user.
