Authentication Component for Roaming Policy Transfer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is no mechanism to transfer service-level policy information between fixed IP access networks and wireless access networks, preventing wireless access policies from being enabled on fixed IP access networks, which hinders seamless communication across different network architectures.
Innovation Solution
Systems and methods are provided to facilitate the transfer of a portion of a service-level policy agreement between a home wireless access network and a fixed IP access network, enabling authentication and dynamic negotiation of service-level agreements to regulate per-session data exchange and quality of service parameters, thereby enabling seamless service-level policies across wireless and fixed IP access networks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If service-level policy information is not transferred between fixed IP access networks and wireless access networks, then network architecture independence is maintained, but seamless communication and consistent quality of service across different network architectures cannot be achieved
Solution Approach 1:
The patent introduces an authentication component as an intermediary that mediates between the fixed IP access network and the wireless access network. This component receives identification data from the fixed IP network, forwards authentication requests to the home wireless access network, and transfers service-level policy information between the networks. The intermediary enables seamless communication and consistent QoS across different network architectures without requiring direct complex integration between the networks themselves.
2Ease of operation
If automatic authentication and policy transfer mechanisms are implemented, then seamless roaming and service consistency are achieved, but system complexity and authentication overhead increase
Solution Approach 1:
The patent implements preliminary action by pre-establishing service-level policy agreements between wireless access networks before roaming occurs. When a device seeks authentication in a fixed IP access network, the authentication component already has the necessary policy information ready to transfer, enabling seamless roaming without real-time complex negotiations. The home wireless access network maintains pre-configured service-level policies that can be quickly authenticated and transferred.
Solution Approach 2:
The authentication component implements feedback mechanisms by receiving authentication results from the home wireless access network and using this information to determine whether to grant access and what service-level policies to apply. The system continuously exchanges authentication data and policy information between networks, adjusting service delivery based on confirmed subscriber status and applicable agreements, thereby managing complexity through structured feedback loops.
3Reliability
If service-level policies are established on a per-session basis, then flexible and consistent quality of service is provided, but processing overhead and authentication time increase
Solution Approach 1:
The patent applies copying by transferring service-level policy information from the home wireless access network to the authentication component in the fixed IP access network. Instead of creating entirely new policies for each session, the system copies and applies pre-established service-level agreements that define quality of service parameters. This copying mechanism ensures consistent QoS across networks while reducing authentication time, as the policy framework already exists and只需 be transferred and applied rather than negotiated from scratch.

AI summary
Roaming support for wireless access subscribers over fixed IP access networks is provided herein. An authentication component can authenticate a subscription of a multi-mode device across different network architectures. A policy component can provide at least a portion of a service-level policy agreement to enable or disable services or policies associated with a multi-mode device at the fixed IP access network on a per session basis.
