Mobile-IP Update Notifications via AAA Extensions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for notifying mobile devices of software and firmware updates rely on SMS infrastructure, which is not efficient for Mobile-IP devices that require continuous network connectivity and authentication processes.
Innovation Solution
Utilizing Mobile-IP extensions within the Mobile-IP registration process to convey update availability between the AAA server, NAS, and mobile device, eliminating the need for SMS messages by appending an 'is UpdateAvailable' extension to the registration-reply message.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If SMS infrastructure is used to notify mobile devices of updates, then update notifications can be delivered to devices, but the system becomes dependent on SMS infrastructure and less efficient for Mobile-IP devices requiring continuous connectivity
Solution Approach 1:
The patent combines the update notification function with the existing Mobile-IP registration process. The AAA server, which already handles authentication and authorization, is extended to also provide update availability information through the Mobile-IP extension mechanism. This eliminates the need for separate SMS infrastructure by merging two functions into a single integrated system.
Solution Approach 2:
The Mobile-IP registration process is enhanced to serve multiple purposes: authentication, authorization, and update notification. The AAA server becomes a multi-functional entity that not only manages device access but also distributes software update information, reducing dependency on specialized SMS infrastructure.
2Productivity
If Mobile-IP extensions are used to convey update availability, then update notifications are integrated into the Mobile-IP session establishment process, but the message structure becomes more complex
Solution Approach 1:
The update availability information is nested within the existing Mobile-IP registration reply message structure. Rather than creating a separate communication channel or standalone message, the update notification is embedded as an extension field within the already-established Mobile-IP protocol framework, allowing efficient delivery without requiring separate message handling.
3Loss of time
If update information is provided during Mobile-IP session establishment, then devices receive timely update notifications without additional communication overhead, but the authentication and authorization process becomes more complex
Solution Approach 1:
The update availability information is provided during the initial Mobile-IP session establishment phase, before the device engages in normal data transmission. By delivering update notifications during this preliminary authentication and authorization phase, the system ensures devices are informed of available updates before they begin their primary operations, eliminating the need for separate update check procedures.

AI summary
The present invention provides systems and methods for notifying mobile devices of the presence of software and/or firmware updates using Mobile-IP extensions. When a mobile device seeks to engage in a Mobile-IP session, it sends a Mobile-IP registration request message. When it receives a reply to the registration request, the reply includes a Mobile-IP extension that indicates whether an update is available for the mobile device. If the extension indicates that an update is available, the mobile device responsively obtains the update.
