Foreign Agent Selective Device-ID Insertion in Mobile IP Registration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In Mobile IP registration processes, there is a need to selectively communicate device-ID to a home agent while maintaining confidentiality and avoiding unnecessary resource consumption, as current methods either do not convey device-ID or do so consistently, which can be resource-intensive.
Innovation Solution
A mechanism is introduced to selectively insert a device-ID into the Mobile IP registration request based on a user-ID, allowing the device-ID to be communicated only when necessary, using a foreign agent that can insert the device-ID into the registration request without disrupting the standard Mobile-IP registration process, utilizing a Normal Vendor/Organization Specific Extension or RADIUS Vendor Specific Attribute for secure and efficient transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If device-ID is consistently included in Mobile IP registration requests, then fraud detection capability is improved, but network resource consumption increases
Solution Approach 1:
The patent changes the parameter of device-ID inclusion from a constant state (always included) to a variable state (conditionally included based on user-ID). The foreign agent modifies the registration request by inserting device-ID only when the user-ID matches specific criteria stored in its database, thereby reducing unnecessary resource consumption while maintaining fraud detection capability for high-risk users.
Solution Approach 2:
The patent applies different quality levels of information inclusion to different users. Instead of uniformly including device-ID for all users, the foreign agent selectively includes device-ID only for specific users identified by their user-ID, creating a localized, differentiated approach that optimizes resource usage while maintaining security for targeted users.
2Productivity
If device-ID is selectively included based on user-ID, then resource efficiency is improved, but system complexity increases
Solution Approach 1:
The foreign agent performs the selection and insertion operations autonomously based on pre-stored user-ID criteria in its database. The system does not require external control or complex coordination with other network elements - the foreign agent independently determines whether to include device-ID based on the user-ID in the registration request, thereby managing the increased complexity through self-service automation.
Solution Approach 2:
The foreign agent pre-stores user-ID criteria and corresponding device-ID insertion decisions in its database before processing registration requests. This preliminary preparation allows the foreign agent to quickly determine whether to include device-ID without performing complex real-time analysis, thereby reducing the operational complexity during actual registration processing.

AI summary
A method and system for selectively including a device-ID within a Mobile-IP registration request. A foreign agent, AAA server or other entity decides, based at least in part on a user-ID carried in a Mobile-IP registration request from a mobile node, whether to insert a device-ID of the mobile node into the registration request. In response to a decision to insert the device-ID, the foreign agent or another entity inserts the device-ID into the registration request and sends the request, including the device-ID, along to a Mobile-IP home agent.
