AAA Server Domain Identifier Protocol Authorization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wireless communication systems face challenges in supporting multiple domains due to the development of different communications protocols, which impedes efficient protocol service authorization and assignment for mobile devices.
Innovation Solution
An authentication, authorization, and accounting (AAA) server authenticates a mobile device and provides a domain identifier, allowing the access gateway to determine compatible protocols and configure communication parameters for the mobile device, facilitating protocol service assignment based on the specified domain.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple communication protocols and domains are supported, then network versatility is improved, but protocol service authorization complexity increases
Solution Approach 1:
The patent introduces a domain identifier as an intermediary element that mediates between the user profile and protocol selection. The domain identifier acts as a bridge, allowing the network to translate high-level domain requirements into specific protocol configurations without increasing overall system complexity. This intermediary simplifies the authorization process by providing a clear mapping between domains and compatible protocols.
Solution Approach 2:
The patent changes the parameter used for protocol selection from direct protocol matching to domain-based identification. By using domain identifiers instead of directly managing multiple protocol configurations, the system transforms the complexity management approach. The domain identifier serves as a key parameter that, when changed or updated, automatically triggers the appropriate protocol selection without requiring complex real-time decision logic.
2Ease of operation
If protocol service authorization is simplified, then ease of operation is improved, but network adaptability to multiple domains decreases
Solution Approach 1:
The domain identifier provides universality by serving multiple functions: it identifies the user's preferred domain, determines compatible protocols, and guides protocol service authorization. This multi-functional approach allows a single simplified mechanism to handle multiple domain requirements, maintaining both ease of operation and network adaptability. The universal domain identifier replaces the need for separate protocol selection mechanisms for each domain.
3Reliability
If new protocol addresses are assigned during device transfers, then protocol compatibility is maintained, but network resource consumption increases
Solution Approach 1:
The system performs preliminary action by determining protocol compatibility and assigning protocol addresses before device transfers occur. The domain identifier is used to pre-determine which protocols are compatible with the user's profile and domain requirements. This preliminary protocol selection and address assignment ensures that when device transfers happen, the network already has the necessary protocol information ready, avoiding the need for real-time protocol address reassignment and reducing network resource consumption during transfer events.

AI summary
Systems and methodologies are described that facilitate protocol address assignment using protocols compatible with specified domains for mobile devices. Devices can request wireless network access through a gateway, which can forward an authentication/authorization request to an authentication server. Upon successful authentication, the authentication server can transmit one or more domain identifiers related to the device or a user thereof. Using the domain identifier, compatible protocols can be determined for use in configuring the device for subsequent domain communication.
