Onboarding Access Control for Private Network Congestion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems fail to manage network congestion during the onboarding and provisioning of user equipment (UE) in Fifth Generation Non-Public Networks (NPNs), particularly when a large number of UEs attempt to access the network simultaneously, leading to congestion and unauthorized access attempts.
Innovation Solution
Implementing onboarding access control information in the radio access network (RAN) to guide UEs to the correct network, prevent unauthorized access, and manage congestion by broadcasting lists of supported subscription owners (SOs) or groups, using group identifiers, and controlling access based on predefined configurations and wait times.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If the onboarding network allows all UEs to access simultaneously, then onboarding speed is improved, but network congestion increases
Solution Approach 1:
The system performs preliminary actions by broadcasting onboarding access control information before UE attachment, including lists of supported subscription owners and congestion status. This allows UEs to make informed network selection decisions in advance, reducing simultaneous access attempts and preventing congestion before it occurs.
Solution Approach 2:
The system implements feedback mechanisms where the radio access network broadcasts current network status and supported SO lists to UEs. Based on this feedback, UEs adjust their onboarding behavior by selecting appropriate networks, thereby regulating traffic and preventing congestion while maintaining efficient onboarding speeds.
2Adaptability or versatility
If the network provides comprehensive onboarding services to all subscription owners, then service coverage is improved, but network load increases
Solution Approach 1:
The system applies local quality by providing differentiated onboarding services based on the specific subscription owner and network conditions. The radio access network broadcasts supported SO lists and congestion-specific information, allowing selective service provision to appropriate UEs while denying access to others, thus managing network load while maintaining comprehensive coverage capability.
Solution Approach 2:
The system implements dynamics by making onboarding availability flexible and condition-based rather than static. The network dynamically adjusts onboarding acceptance based on real-time congestion status and supported SO lists, allowing the system to adapt service coverage to current network capacity requirements.
3Measurement precision
If the network broadcasts detailed access control information to all UEs, then access control precision is improved, but information overhead increases
Solution Approach 1:
The system applies segmentation by dividing access control information into manageable components: supported SO lists, congestion status indicators, and network availability flags. This segmented approach provides precise access control guidance while minimizing information overhead compared to broadcasting complete access control databases to all UEs continuously.

AI summary
A system and method for reducing congestion in onboarding networks before onboarding and provisioning connections are made by user equipment (UE), and for reducing congestion in onboarding networks after attempts are made by UEs to make connections to onboarding networks for onboarding and provisioning which result in network congestion. Broadcast information (referred to herein as “onboarding access control information”) from a radio access network (RAN) to user equipment (UE) is used in order to guide onboarding UEs to detect and access the right onboarding network to prevent unnecessary network access attempts by UEs which are not authorized to access an onboarding network for onboarding.
