Femtocell Access Time Notification and Extension Negotiation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In 3GPP LTE wireless communication systems, users are not informed of the duration of their access period to femtocells and cannot negotiate extensions, leading to unexpected disconnections.
Innovation Solution
A method and apparatus that notify users of their access time period and allow them to request extensions, using a communication system that determines access periods based on group policies and owner/operator settings, enabling users to anticipate and manage their connection time.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If access time period is limited for UE to camp on CSG cell, then network access control and security are improved, but user experience deteriorates due to unexpected disconnections and lack of transparency
Solution Approach 1:
The system implements feedback by notifying the user of the access time period duration before expiration. The notification mechanism provides users with advance warning (e.g., when remaining time falls below a threshold), allowing them to take appropriate actions such as requesting extensions or finding alternative networks, thereby improving user experience while maintaining access control
Solution Approach 2:
The system performs preliminary action by notifying users in advance before the access time period expires. This allows users to prepare for disconnection or request extensions before being forcibly disconnected, reducing the negative impact of time-limited access on user experience
2Reliability
If access time period is configured by owner/operator, then network security and control are improved, but user autonomy deteriorates as users cannot negotiate or extend access
Solution Approach 1:
The system introduces dynamics by allowing the access time period to be extended through user requests and owner/operator approval. The initially static time limit becomes flexible, enabling users to negotiate extensions based on their needs and the owner's policies, thus improving user autonomy while maintaining security controls
Solution Approach 2:
The system implements a feedback loop where users can request extensions and owners/operators can approve or deny these requests. This interactive mechanism balances security control with user autonomy, allowing users to have a say in their access duration while maintaining owner oversight
3Ease of operation
If no access time period is configured, then user convenience is improved with unlimited access, but network control and security deteriorate
Solution Approach 1:
The system uses parameter changes by setting a default maximum time period value that can be configured by owners/operators. This parameter can be adjusted based on security requirements, allowing flexible balancing between user convenience and network control without requiring complex policies for each user

AI summary
In a wireless communication system wherein a user equipment (UE) that accesses a cell served by an access point (sometimes known as femtocell) is granted only a limited time period during which to camp on, attach to, or connect to the cell, the communication system permits a user of the UE to anticipate an expiration of the time period and, if desired negotiate an extension of the time period. More particularly, the communication system provides for notification of the UE of the duration of this limited time period and further permits the UE to negotiate an extension of the time period when the UE desires to do so. In the event an extension is requested by the user and granted by the owner/operator, a notification will be sent to the user and the UE may reset a timer.
