Joint Satellite Cellular Interception via Unified Signal Processing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current communication interception systems are inadequate in simultaneously tracking targets across both satellite and cellular networks, as they often require separate processing and infrastructure for each network, leading to inefficiencies and increased costs.
Innovation Solution
A system comprising front-end receivers for satellite and cellular signals and a processing unit that jointly processes and correlates information from both networks using shared hardware, such as Software Defined Radio modules and decryption hardware, to track targets across both networks, storing data in a single structure and presenting a unified interface to operators.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate processing systems are used for satellite and cellular networks, then each network can be intercepted independently, but system complexity and costs increase
Solution Approach 1:
The patent combines separate satellite and cellular interception systems into a unified processing platform. The processing unit integrates signal processing for both satellite communications and cellular communications, allowing simultaneous interception and correlation of targets across both networks through a single system rather than separate independent systems
Solution Approach 2:
The processing unit is designed with multi-functionality to handle diverse signal types from both satellite and cellular networks. It can process satellite signals, cellular signals, correlate identifiers across networks, and provide unified tracking, making a single system capable of performing multiple interception functions that previously required separate dedicated systems
2Reliability
If separate infrastructure is used for satellite and cellular interception, then each network can be monitored independently, but costs increase
Solution Approach 1:
The patent merges the infrastructure requirements for satellite and cellular interception into a single shared platform. The processing unit, database, and correlation mechanisms are consolidated, reducing the total quantity of hardware and software resources needed compared to maintaining separate independent infrastructure for each network type
Solution Approach 2:
The interception system is designed as a universal platform that can monitor both satellite and cellular networks simultaneously. The processing unit and associated infrastructure serve multiple functions including satellite signal processing, cellular signal processing, identifier correlation, and unified target tracking, eliminating the need for duplicate specialized infrastructure
3Productivity
If joint processing is implemented, then tracking efficiency improves, but processing complexity increases
Solution Approach 1:
The patent merges satellite and cellular signal processing into a unified processing workflow. The processing unit simultaneously handles both signal types and performs correlation of identifiers across networks, improving tracking efficiency by consolidating data from both sources rather than processing them separately and manually correlating results
Solution Approach 2:
The processing unit automatically performs identifier correlation between satellite and cellular networks without requiring manual intervention. The system self-service correlates targets by extracting and matching identifiers across different network types, and automatically presents unified tracking results, reducing the operational complexity despite the advanced processing capabilities
Data Source
AI summary
Methods and systems for communication interception that apply joint processing to signals and information obtained from a satellite communication network and from a cellular communication network. A processing unit processes intercepted signals from the satellite and cellular networks using shared hardware. The processing unit extracts information related to target users from communication sessions conducted by the target users in the satellite and cellular networks. The processing unit may store this information in a single data structure, and in particular correlate information pertaining to the same target user in the two networks. The processing unit may correlate the different identifiers used by the target user in the different networks, and use this correlation to enhance the tracking of this user.
