AAA Server Home Agent Selection for MVNOs
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional wireless communication networks face challenges in determining the appropriate home agent for wireless terminals during registration, especially in scenarios involving multiple mobile virtual network operators (MVNOs), which affects mobility management and service provision.
Innovation Solution
A method and apparatus that involve receiving identifying indicia from a wireless terminal, determining the associated home agent through a AAA server, and routing registration information to the identified home agent, allowing for the selection of the most suitable home agent based on geographic proximity, resource availability, or other criteria.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional PSDN is used to determine home agent association, then wireless terminal can be registered with mobility management server, but the system cannot adapt to multi-MVNO environments where multiple home agents need to be selected
Solution Approach 1:
The patent introduces a AAA server as an intermediary component that mediates between the wireless terminal and multiple home agents. The AAA server receives identifying indicia from the terminal, determines the appropriate home agent based on MVNO affiliation, and facilitates the registration process. This intermediary approach enables multi-MVNO support without requiring complex selection logic in the terminal or base station.
2Reliability
If multiple home agents are available for selection, then service reliability can be improved through load balancing and geographic proximity, but the difficulty of detecting and measuring the appropriate home agent increases
Solution Approach 1:
The system implements a feedback mechanism where the AAA server receives identifying indicia from the wireless terminal, queries information about MVNO affiliation and home agent availability, and uses this feedback to determine the most appropriate home agent. The server can consider multiple factors including load conditions and geographic proximity, then provides the selected home agent identity back to the terminal for registration.
3Measurement precision
If home agent selection is centralized in AAA server, then selection accuracy improves, but the processing load and energy consumption of the AAA server increases
Solution Approach 1:
The AAA server performs partial processing by determining home agent identity based on available information such as MVNO affiliation from identifying indicia. The server does not need to evaluate all possible home agents comprehensively, but rather selects from a subset of relevant candidates, reducing the processing load while maintaining sufficient accuracy for the registration function.

AI summary
The claimed subject matter relates to assigning a home agent to a wireless terminal during authentication, authorization, and/or accounting with respect to the wireless terminal. The wireless terminal can provide identifying indicia which can be relayed to a AAA server by way of a base station. The AAA server can then determine one or more home agents that can be associated with the wireless terminal. If more than one home agent can be assigned to the wireless terminal, the base station can resolve which home agent to utilize during registration of the wireless terminal. Such determination can be important with respect to MVNOs.
