Foreign Agent IP Pool Routing for Mobile IP Optimization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing Mobile IP protocol's reverse tunneling process decreases the efficiency of wireless service providers due to additional time and resources spent in sending data packets to each mobile device's home agent during communication between multiple mobile devices.
Innovation Solution
Assigning pools of IP addresses to foreign agents, allowing data packets to be routed directly between foreign agents based on destination IP addresses, thereby bypassing the reverse tunneling procedure and optimizing the communication path.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If reverse tunneling is used to send data packets to mobile devices' home agents, then mobile devices can maintain permanent IP addresses and connectivity, but the time and resources required for data transmission increase
Solution Approach 1:
The patent segments the IP address space into multiple pools, with each pool assigned to a specific foreign agent. This segmentation allows foreign agents to directly route packets to mobile devices based on their assigned IP pools, eliminating the need for reverse tunneling through home agents and reducing transmission time while maintaining connectivity.
Solution Approach 2:
The patent introduces foreign agents as intermediaries that hold binding information between mobile devices and their home agents. These foreign agents can directly forward packets to mobile devices using their assigned IP pools, acting as mediators that eliminate the need for time-consuming reverse tunneling operations while preserving mobile device connectivity.
2Reliability
If reverse tunneling is used to send data packets to mobile devices' home agents, then mobile devices can maintain permanent IP addresses, but the resources consumed by wireless service providers increase
Solution Approach 1:
The patent segments IP addresses into dedicated pools assigned to each foreign agent. This segmentation enables foreign agents to directly route packets to mobile devices without requiring reverse tunneling operations, significantly reducing the computational and networking resources consumed by wireless service providers while maintaining reliable mobile device connectivity.
Solution Approach 2:
The patent enables foreign agents to autonomously manage packet routing to mobile devices using their assigned IP pools. This self-service capability allows foreign agents to directly forward packets without requiring resource-intensive reverse tunneling operations through home agents, reducing service provider resource consumption while preserving connectivity.
3Device complexity
If IP addresses are assigned from a single pool, then IP address management is simple, but communication efficiency between mobile devices decreases
Solution Approach 1:
The patent segments the IP address pool into multiple smaller pools, with each pool assigned to a specific foreign agent. This segmentation improves communication efficiency by enabling direct routing between foreign agents based on their assigned IP pools, while the overall system complexity remains manageable through automated pool assignment and binding information maintenance.
Data Source
AI summary
A method, system, and computer-readable media are provided for creating an optimized communication path between mobile devices. The method includes receiving a request to transmit data to a destination mobile device, and identifying a destination IP address of a destination mobile device within the request. The method further includes determining if the destination IP address is located within a routing table, and bypassing a reverse tunneling procedure if the destination IP address is located within the routing table. Additionally, the method includes transmitting the data directly to destination foreign agent of the destination mobile device.
