Lawful Intercept Tokenization Bandwidth Optimization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bandwidth optimization solutions in mobile networks do not effectively support Lawful Intercept functionality when tokens are used, as they do not allow for the interception of content passing through sites comprising an Intercept Access Point, leading to inefficiencies in bandwidth usage and network capacity.
Innovation Solution
A method and system that generate and send tokens for original content over a synchronization plane to nodes or User Equipments with restore functionality, enabling efficient bandwidth optimization and Lawful Intercept by storing and restoring the content using separate transmission links, thereby reducing bandwidth usage and enhancing network capacity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If tokens are used for bandwidth optimization in mobile networks, then bandwidth usage is reduced and network capacity is enhanced, but Lawful Intercept functionality is lost because intercepted content cannot be captured when data passes through sites comprising an Intercept Access Point as a token
Solution Approach 1:
The system segments the content delivery path into two separate planes: a synchronization plane for delivering original content and tokens to IAPs, and a user plane for delivering tokens to UEs. This segmentation allows the IAP to intercept original content on the synchronization plane while the UE receives only tokens on the user plane, resolving the contradiction between bandwidth optimization and Lawful Intercept capability.
Solution Approach 2:
The Intercept Access Point (IAP) acts as an intermediary that receives both original content and tokens through the synchronization plane. It can then intercept the original content for Lawful Intercept purposes while allowing tokens to continue to the UE for bandwidth-efficient delivery. This intermediary role enables both bandwidth optimization and Lawful Intercept functionality to coexist.
2Reliability
If original content is sent to all nodes with restore functionality for synchronization, then Lawful Intercept capability is maintained, but bandwidth usage increases
Solution Approach 1:
The system separates content delivery into two distinct paths: the synchronization plane where original content is delivered to IAPs for interception purposes, and the user plane where only compact tokens are delivered to UEs. This segmentation enables Lawful Intercept capability to be maintained on the synchronization plane while bandwidth usage is optimized on the user plane through token-based delivery.
Solution Approach 2:
Different quality levels of data delivery are applied to different destinations: full original content is delivered to IAPs that require it for Lawful Intercept functionality, while only compressed tokens are delivered to UEs that do not require original content for their operation. This local quality differentiation resolves the contradiction between maintaining interception capability and optimizing bandwidth usage.
