Session Continuity Controller for Lawful Interception Transmission
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Lawful interception content transmission across networks often fails due to buffer-overflow and insufficient network resources, leading to defective or failed content packet delivery to Law Enforcement Agencies, causing delays and quality issues.
Innovation Solution
A session continuity server controller determines defects in lawful interception content transmission, executes corrective measures such as selecting new content duplication elements and session continuity servers based on network conditions, and ensures stability to maintain effective and reliable content transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If content duplication and aggregation are performed during lawful interception, then content transmission capability is improved, but buffer-overflow and insufficient network resources cause transmission failures
Solution Approach 1:
The system performs preliminary defect detection and network condition assessment before content transmission. The session continuity server controller proactively identifies potential transmission issues and executes corrective measures in advance, preventing buffer-overflow and resource exhaustion before they cause transmission failures.
Solution Approach 2:
The system implements continuous monitoring of network conditions and transmission quality, using this feedback to dynamically adjust transmission parameters. The controller detects defects in real-time and executes corrective measures based on current network state, ensuring reliable transmission under varying conditions.
2Reliability
If network resources are increased to prevent buffer-overflow, then transmission reliability is improved, but network cost and complexity increase
Solution Approach 1:
The system dynamically adjusts transmission parameters and resource allocation based on current network conditions. Rather than provisioning for maximum capacity statically, the controller adapts buffer sizes, transmission rates, and aggregation levels to match actual network state, reducing overall resource requirements while maintaining reliability.
Solution Approach 2:
The system changes operational parameters such as buffer thresholds, aggregation window sizes, and transmission priorities based on detected network conditions. This allows the same network infrastructure to support reliable transmission under varying loads without requiring additional resources.
3Productivity
If content aggregation is performed to improve transmission efficiency, then productivity is improved, but buffer-overflow causes aggregation failure
Solution Approach 1:
The system determines network conditions and defect states before performing content aggregation. By assessing buffer availability and network capacity in advance, the controller can safely aggregate content without risking buffer-overflow, maintaining both efficiency and reliability.
4Productivity
If transmission speed is increased to reduce delays, then productivity is improved, but insufficient network resources cause transmission failures
Solution Approach 1:
The system dynamically adjusts transmission speed based on real-time network conditions. When resources are available, transmission proceeds at high speed; when resources are constrained, the controller reduces speed to prevent failures. This maintains high productivity while ensuring reliable delivery.
