User Profile-Based Network Access Restriction for 2G/3G Phaseout
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems lack flexibility and robustness in decommissioning early-generation network technologies, such as 2G and 3G, as they typically consider only one variable, failing to account for user-specific factors like MNO subscription, device type, and user activity, leading to potential disruptions.
Innovation Solution
Implementing a restriction module that retrieves user profile information, including MNO, device, and roaming subscriber data, to selectively restrict users from accessing specific network technologies based on a logic flow, modifying the Roaming Subscriber Information (RSI) to enforce access restrictions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional systems are used for phased decommissioning, then a basic phased approach is enabled, but flexibility and adaptability are insufficient
Solution Approach 1:
The system segments users into different groups based on multiple criteria (MNO subscription, device type, user activity status) and applies different restriction strategies to each segment. This allows flexible targeted restriction while maintaining a manageable system structure through modular evaluation rules.
Solution Approach 2:
The restriction system is made dynamic by continuously evaluating user profile information and allowing real-time modification of restriction status. The system can adapt restriction policies based on changing user conditions, such as activity status changes or device updates, providing flexibility without requiring complete system redesign.
2Adaptability or versatility
If user profile information is retrieved and evaluated, then selective restriction capability is improved, but system complexity and processing requirements increase
Solution Approach 1:
The system divides user profile evaluation into distinct segments or criteria (MNO subscription type, device category, activity status) that can be independently evaluated. This modular approach enables targeted restriction capabilities while keeping each evaluation component simple and manageable.
Solution Approach 2:
The restriction module is designed to handle multiple types of user profile information and apply universal restriction logic across different user categories. This multi-functional approach allows the same module to serve various restriction scenarios without requiring separate complex systems for each user type.
3Reliability
If early-generation technologies are decommissioned, then network modernization is achieved, but user disruptions may occur
Solution Approach 1:
The system performs preliminary evaluation of user profiles and proactively applies restrictions before complete technology decommissioning occurs. By identifying users who will be affected and applying restrictions in advance, the system enables smooth transitions to newer technologies while minimizing sudden disruptions to users.
Solution Approach 2:
The restriction application is localized to specific user groups and specific technologies based on evaluated criteria. Instead of blanket restrictions, the system applies targeted restrictions only to users and technology combinations that meet specific conditions, thereby modernizing the network while preserving service quality for affected users through selective rather than universal application.

AI summary
Systems and methods are contemplated herein for determining whether to restrict a user's access to one or more network technologies. The method may include receiving, at a restriction module, an indication to initiate a logic flow. The method may include retrieving, by the restriction module during the logic flow, user profile information associated with the user. The method may include determining, based on the user profile information associated with the user, whether to exclude the user from restriction or restrict the user's access to the one or more network technologies.
