IP Version Authorization in Mobile Authentication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In the context of increasing dual-stack devices capable of communicating with both IPv4 and IPv6, existing authentication processes often waste resources by attempting to authenticate devices for both IP versions, even if they are only authorized for one, leading to inefficiency.
Innovation Solution
The method involves determining a mobile device's authorized IP version(s) early in the authentication process by inspecting authorization information in a customer-profile database and communicating this information to authentication and packet-routing components, allowing only necessary authentication steps for the authorized IP version(s) to be taken.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If authentication processes attempt to authenticate devices for both IPv4 and IPv6, then devices capable of both protocols can be supported, but resource waste occurs when devices are only authorized for one version
Solution Approach 1:
The patent applies preliminary action by determining the authorized IP version (IPv4 or IPv6) at the beginning of the authentication process, before actual authentication steps are executed. The system queries the customer-profile database to retrieve authorization information and caches it in the packet-routing component, ensuring that only necessary authentication steps for the authorized IP version are performed subsequently, thereby avoiding waste of authentication resources on unauthorized versions.
2Loss of energy
If authentication processes determine IP version authorization early, then resource efficiency improves, but additional database queries and information management steps are required
Solution Approach 1:
The patent merges the authorization determination step with the existing authentication process by integrating a database query to the customer-profile database and caching mechanism in the packet-routing component. This combination allows the system to retrieve and store IP version authorization information in a centralized manner, reducing redundant operations and managing the additional complexity through structured information flow rather than separate standalone processes.
3Productivity
If only necessary authentication steps for authorized IP version are performed, then authentication efficiency increases, but the system must accurately identify and filter authorized versions
Solution Approach 1:
The patent implements feedback by continuously querying the customer-profile database to retrieve accurate authorization information and caching it in the packet-routing component. This feedback mechanism ensures that the authentication system has real-time access to the correct IP version authorization status, enabling precise determination of which authentication steps to perform while maintaining high processing speed through the cached information.
Data Source
AI summary
Methods and computer-readable media are provided to enable an Internet protocol (IP) data session to be established between a mobile device and a telecommunications network. To establish an IP data session, it may be determined, prior to authenticating the device, whether the device is authorized to communicate via IPv4, IPv6, or both. A mobile device may be capable of communicating via both IPv4 and IPv6, such as a dual-stack device, but the device may only be authorized for either IPv4 or IPv6. A request to establish the IP data session may first be received from a mobile device, and an IP version with which the mobile device is authorized to communicate may then be determined by querying a customer-profile database. This authorization information may be communicated to an authentication component that authenticates the devices, and subsequently, an IP data session is initiated.
