Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Intercepting communications in complex and distributed wireless networks is challenging, particularly when multiple copies of data are generated, leading to authentication issues and capturing more data than requested.
Innovation Solution
Utilizing a Data Network Name (DNN) to configure 5G network functions to intercept specific data types based on intercept requests, enabling efficient duplication and transmission of targeted communications data to law enforcement agencies.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple network functions intercept communications data in a distributed wireless network, then the intercept request can be fulfilled comprehensively, but duplicate data is generated leading to authentication issues
Solution Approach 1:
The patent segments the intercept request processing by assigning different network functions to handle different data types (e.g., UPF for internet data, IMS for voice data). Each network function intercepts only its assigned data type, preventing duplicate interception of the same data while ensuring comprehensive coverage of all requested data types.
Solution Approach 2:
The patent extracts and processes only the specific data types requested in the intercept request. The admin function provisions network functions to selectively intercept only the requested data types (e.g., internet data, voice data, MMS data) rather than all communications data, thereby avoiding generation of unnecessary duplicate data.
2Reliability
If all communications data is intercepted regardless of type, then no data is missed, but data type specificity and authentication become problematic
Solution Approach 1:
The patent applies local quality by configuring each network function with specific interception rules for its assigned data type. The UPF is configured to intercept only internet data, while the IMS is configured to intercept only voice data. This localized specialization ensures that each function handles only the data type it is designed for, maintaining authenticity while simplifying management.
Solution Approach 2:
The patent changes the parameter of data type specificity by using DNN (Data Network Name) to identify and route different data types to appropriate network functions. This parameter-based routing ensures that only the requested data types are intercepted by the appropriate functions, eliminating unnecessary intercepts and simplifying request management.
3Quantity of substance
If network functions are configured to intercept specific data types, then duplicate intercepts are reduced, but configuration complexity increases
Solution Approach 1:
The patent introduces an admin function as an intermediary that automatically provisions and configures network functions based on intercept requests. The admin function receives the intercept request, determines which network functions should handle which data types, and configures them accordingly. This intermediary automation reduces configuration complexity while maintaining precise control over data type-specific interception.
Solution Approach 2:
The patent implements feedback mechanisms where network functions report intercepted data types and quantities back to the admin function. This feedback allows the system to monitor and adjust configurations to prevent duplicate intercepts, automatically reducing configuration complexity through adaptive management rather than manual setup.
Data Source
AI summary
A system may receive, a request for communications data of a first data type and a second data type, the communications data associated with a target user equipment. The system may provision the wireless network to fulfill the request for communications data. The system may configure a first network function to generate first duplicated data, and a second network function to generate second duplicated data. The system may receive a first communication of the first data type and a second communication of the second data type. The system may generate the first duplicated data based on the first communication and transmit the first communication to a respective intended recipient and the first duplicated data to a mediation and delivery function. The system may generate the second duplicated data and transmit the second communications data to the respective destination and the second duplicated data to the mediation and delivery function.
