Smart IP Address Context Engine for Mobile Network Latency
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless communication networks, particularly for users on fast-moving platforms like aircraft, the assumption of a fixed IP address location leads to inaccurate service provision and increased latency due to long-distance data transmission, causing issues with location-based services and advertisements.
Innovation Solution
A context awareness engine is employed to provide a dynamic, 'smart' IP address that updates context information based on the actual location of mobile communication nodes, allowing content servers to tailor responses to the user's current location rather than the connection point's location.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the terminal uses a fixed PGW association based on initial connection point, then network simplicity and connection stability are maintained, but latency increases and service accuracy deteriorates when the terminal moves to distant locations
Solution Approach 1:
The patent implements dynamic PGW selection based on terminal location. Instead of a static PGW association, the system dynamically determines the optimal PGW by evaluating terminal position relative to multiple candidate PGWs, selecting the one that minimizes transmission distance and latency while maintaining connection stability through controlled handovers.
Solution Approach 2:
The patent introduces a location management function as an intermediary between the terminal and PGW selection process. This intermediary tracks terminal position, evaluates candidate PGWs, and orchestrates handovers to optimize the terminal-PGW association, separating location awareness from the core data path to maintain simplicity.
2Loss of time
If the terminal changes its homed PGW and obtains a new IP address during travel, then latency is reduced for distant locations, but all established connections based on source and destination IP addresses are disconnected
Solution Approach 1:
The patent performs preliminary evaluation of candidate PGWs before triggering a handover. By assessing location-based metrics in advance and preparing for potential PGW changes, the system can initiate handovers proactively before latency becomes problematic, while coordinating with the terminal to maintain or seamlessly transfer active connections.
Solution Approach 2:
The patent implements feedback mechanisms that monitor terminal position, latency metrics, and connection status. This feedback loop enables the system to detect when a PGW change is beneficial and coordinate the handover process to minimize disruption to established connections, balancing latency optimization with connection continuity.
3Device complexity
If the network assumes the connection point location as the terminal's actual location, then network simplicity is maintained, but location-based services become inaccurate or unusable
Solution Approach 1:
The patent segments the network functions into location-aware components and data plane components. The location management function handles position tracking and PGW selection, while the data plane maintains simple IP routing. This segmentation allows location accuracy improvements without significantly increasing overall network complexity.
Solution Approach 2:
The patent creates a multi-functional location management mechanism that serves multiple purposes: tracking terminal position for service accuracy, determining optimal PGW selection for latency optimization, and coordinating handovers for connection continuity. This universal function reduces the need for separate specialized systems.

AI summary
A context awareness engine may include processing circuitry configured to receive a context update request from a content provider for an originator of a content request from a source internet protocol (IP) address associated with a dynamic context, determine updated context information for the originator based on the source IP address, and provide the updated context information to the content provider to enable the content provider to provide a response to the content request including requested content or additional content that is based on the updated context information.
