Network Authorization for Mobile Devices via Non-Traditional Entry Points
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wireless service providers face challenges in implementing subscription-based services for mobile devices accessing networks via non-traditional entry points, such as unlicensed IP networks, due to the transparent nature of IP solutions which can prohibit certain service implementations.
Innovation Solution
A system and method that authorizes mobile devices accessing a carrier's network through non-traditional entry points by determining the type of network used and initiating an authorization process to verify if the device is associated with a subscriber, allowing access via unlicensed networks like Wi-Fi or femtocells while maintaining system compatibility with traditional cellular networks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If IP-based wireless networks are integrated into mobile device telecommunication systems, then service versatility and network compatibility are improved, but implementation of subscription-based services for non-traditional entry points becomes problematic
Solution Approach 1:
The patent introduces an intermediary authorization system that acts as a mediator between mobile devices accessing via non-traditional entry points (IP-based networks) and the core network. This intermediary component determines device eligibility and manages subscription-based services, resolving the contradiction by enabling versatile network access while maintaining manageable service implementation through a dedicated authorization layer.
2Stability of the object's composition
If transparent IP solutions are used for network access, then seamless service continuity is improved, but subscription service implementation for unlicensed networks is prohibited
Solution Approach 1:
The patent applies local quality by implementing differentiated authorization policies for different network access types. The system maintains transparent IP-based access for seamless service continuity while applying specific subscription-based service restrictions only where appropriate, allowing flexible service implementation that respects both continuity requirements and subscription models.
3Ease of operation
If non-traditional entry points like Wi-Fi and femtocells are enabled, then wireless access flexibility is improved, but system compatibility with traditional cellular networks is challenged
Solution Approach 1:
The patent implements universality by designing a multi-functional authorization system that handles both traditional cellular network access and non-traditional IP-based access (Wi-Fi, femtocells) through a unified framework. This universal approach enables flexible wireless access while maintaining system compatibility by treating different access types through common authorization principles and interfaces.

AI summary
A system and method for authorizing mobile devices to carrier networks via non-traditional entry points is described. In some examples, the system reviews a registration message sent during establishment of a communication session between the mobile device and the carrier's network to determine the type of access network used by the mobile device. In some cases, the system may identify the base station controller originating the registration message when determining whether the access request came from an IP-based network or other non-traditional entry point.
