Mobile Node Registration via Parallel Binding Updates
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current mobility handoff processes for mobile nodes in foreign networks are inefficient, requiring lengthy wait times for registration with home agents, leading to prolonged downtime and degraded performance.
Innovation Solution
A method that reduces the wait time for mobile nodes to register with their home network by sending Binding Update messages to the next home agent on the list after a significantly shorter threshold period, rather than the traditional 78.5 seconds, allowing for faster engagement of additional home agents in the registration process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the mobile node waits for the traditional 78.5 second threshold period before sending Binding Update messages to the next home agent, then the registration process maintains protocol compliance and stability, but the total registration time becomes excessively long, leading to prolonged downtime and degraded performance
Solution Approach 1:
The patent applies preliminary action by sending Binding Update messages to multiple home agents in parallel before the traditional timeout period expires. Instead of waiting passively for 78.5 seconds before attempting registration with the next home agent, the mobile node proactively initiates registration attempts with multiple home agents simultaneously, thereby reducing total registration time while maintaining protocol compliance through controlled parallel operations.
2Productivity
If the mobile node sends Binding Update messages to multiple home agents in parallel with shorter wait times, then the registration speed increases and downtime is reduced, but the complexity of managing multiple simultaneous registration attempts increases
Solution Approach 1:
The patent applies segmentation by dividing the registration process into manageable segments - specifically, by maintaining a list of home agents and systematically attempting registration with each one in parallel or sequential fashion with reduced timeout periods. This segmentation allows the mobile node to manage multiple registration attempts more efficiently by breaking down the complex multi-agent registration process into discrete, controllable steps.
Solution Approach 2:
The patent applies dynamics by making the registration process adaptive - the mobile node dynamically adjusts its registration strategy based on responses from home agents. When a Binding Update message is sent to multiple home agents, the system dynamically monitors responses and terminates or modifies ongoing registration attempts based on successful or failed outcomes, thereby managing complexity through adaptive control rather than rigid predetermined sequences.
3Ease of manufacture
If the mobile node uses the traditional sequential registration approach with long wait times, then the protocol implementation remains simple and straightforward, but the user experience deteriorates due to prolonged service unavailability during handoffs
Solution Approach 1:
The patent applies continuity of useful action by ensuring that the mobile node maintains continuous registration attempts with multiple home agents rather than pausing for long intervals between sequential attempts. By sending Binding Update messages to multiple home agents in parallel with shorter timeout periods, the system eliminates idle waiting time and maintains continuous productive action during the registration process, thereby improving service continuity without significantly complicating the protocol implementation.

AI summary
When a mobile node moves to a network (foreign network) other than its home network, it must register with the home network so that the home agents are able to tunnel messages to the mobile node while it is operating in the foreign network. The present invention enables the mobile node to register with its home network substantially faster than it would take the mobile node to register under the currently available methods. The mobile node of the present invention includes a retrieval module and a registration module that allows it to register with the home network in accordance with the present invention.
