Dual-Stack Router Discovery via AAA Authentication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current solutions for discovering a dual-stack router in mobile communication networks, such as cdma2000, are inefficient in terms of bandwidth and do not optimally address the unique requirements of mobile communication systems, leading to suboptimal load-balancing and router placement.
Innovation Solution
A method where a terminal retrieves the network address of a dual-stack router from a backend network entity through authentication, using a subscription profile and database, and establishes a connection via a gateway functionality, incorporating AAA signaling to select an optimal router based on predetermined criteria.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If current solutions for discovering dual-stack router are used in mobile communication networks, then router discovery is possible, but bandwidth efficiency is poor and load-balancing is suboptimal
Solution Approach 1:
The patent combines the router discovery function with the existing authentication procedure by integrating AAA signaling. The network address retrieval is performed as part of the authentication process, merging two separate operations into one unified flow, thereby improving bandwidth efficiency while maintaining discovery functionality
Solution Approach 2:
The backend network entity is designed to serve multiple functions: it performs authentication, retrieves network addresses, and provides load-balancing capabilities. This multi-functional approach eliminates the need for separate discovery mechanisms, optimizing bandwidth usage while enhancing overall system productivity
2Productivity
If authentication procedure is extended to retrieve network address, then router discovery efficiency improves, but authentication complexity increases
Solution Approach 1:
The patent merges the network address retrieval operation with the existing authentication procedure. By utilizing the already-established AAA signaling framework, the system adds router discovery functionality without creating a separate complex procedure, thus improving efficiency while controlling complexity
Solution Approach 2:
The network address is retrieved during the authentication phase, which occurs before actual data transmission. This preliminary action ensures that the router discovery is completed as part of the initial connection setup, improving overall efficiency without adding complexity to subsequent operations

AI summary
A method, terminal, backend network entity, and system for discovering a network element in a communication system for a terminal, wherein the terminal is establishing a connection to a first part of the communication system, the discovering of the network element comprising a step of retrieving a network address of the network element from a backend network entity of the communication system, wherein the step of retrieving constitutes a part of an authentication of the terminal at the first part of the communication system by means of the backend network entity. Further, the retrieving can be based on a subscription profile of the terminal and/or a database at the backend network entity.
