Non-3GPP Secure Tunnel Paging Priority Under Congestion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Non-3GPP access networks face inefficiencies and resource strain due to maintaining continuous connections and prioritizing critical services during congestion, leading to resource consumption and potential data breaches.
Innovation Solution
A non-3GPP access network device intelligently transitions secure tunnels to an idle state upon UE inactivity and promptly reactivates them based on priority indicators, conserving resources and ensuring critical service delivery.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If continuous connections are maintained between UE and non-3GPP access network, then connection reliability is improved, but network resource consumption increases
Solution Approach 1:
The patent applies dynamics by transitioning secure tunnels between active and idle states based on UE activity status. The network dynamically adjusts connection states rather than maintaining static continuous connections, allowing tunnels to be deactivated when UE is inactive and reactivated when needed, thus balancing reliability and resource consumption.
Solution Approach 2:
The patent changes the operational parameter of secure tunnels from continuously active to state-dependent (active/idle). By modifying the state parameter of tunnels based on UE activity detection, the system achieves reliable connections when needed while conserving resources during inactivity periods.
2Reliability
If secure tunnels are maintained for all UEs, then service availability is improved, but computing resources are consumed
Solution Approach 1:
The system dynamically manages secure tunnel states based on UE activity. When UE becomes inactive, tunnels transition to idle state reducing computing resource consumption. When UE becomes active again, tunnels are reactivated to ensure service availability, thus balancing resource usage with service reliability.
Solution Approach 2:
The network device autonomously detects UE activity status and automatically transitions tunnels between states without requiring manual intervention. This self-service mechanism ensures services are available when needed while automatically conserving computing resources during inactivity periods.
3Reliability
If paging messages are sent to all UEs, then critical service delivery is ensured, but network congestion increases
Solution Approach 1:
The patent applies local quality by differentiating treatment of paging messages based on UE priority status. Critical UEs receive prioritized paging delivery while non-critical UEs follow standard procedures. This localized differentiation ensures critical services are delivered reliably without unnecessarily increasing overall network traffic volume.
Solution Approach 2:
The system dynamically adjusts paging message handling based on network congestion conditions and UE priority status. During congestion, the network prioritizes paging delivery for critical services while potentially delaying or filtering paging for non-critical services, thus maintaining critical service reliability without proportionally increasing network throughput requirements.

AI summary
A non-3GPP access network device may establish a secure tunnel for a first UE, and may detect congestion. The non-3GPP access network device may detect a period of inactivity associated with the first UE, and may transition the secure tunnel to an idle state based on detecting the period of inactivity. The non-3GPP access network device may receive a paging message that includes a paging priority indicator, and may identify a critical service priority for the first UE based on the paging priority indicator. The non-3GPP access network device may provide the paging message to the first UE, and may receive, from the first UE, a request to establish a communication with a second UE. The non-3GPP access network device may transition the secure tunnel to an active state based on the request, and may enable the communication between the first UE and the second UE via the secure tunnel.
