Per-UE Priority Access and QoS via UDM/UDR Subscription Data
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless networks lack a granular, per-UE subscription-based mechanism to provide differentiated priority levels and Quality of Service (QoS) parameters to User Equipment (UEs), leading to inefficiencies in resource allocation and user experience.
Innovation Solution
Implementing a system where network functions (NFs) maintain and utilize UE priority level information from a Unified Data Management (UDM) and Unified Data Repository (UDR) to provide subscription-based priority access, allowing NFs to apply specific QoS parameters, queuing, and paging profiles based on individual UE priorities.

Engineering Contradiction Analysis
1Productivity
If a granular, per-UE subscription-based mechanism is implemented to provide differentiated priority levels and QoS parameters, then resource allocation efficiency and user experience are improved, but system complexity increases
Solution Approach 1:
The patent segments the wireless network service into multiple priority levels (e.g., high priority, normal priority, low priority) and assigns different QoS parameters to each level. This segmentation allows the system to manage complexity by breaking down the service differentiation into discrete, manageable categories while improving resource allocation efficiency through targeted resource allocation to each segment.
Solution Approach 2:
The patent implements preliminary action by pre-configuring priority levels and associated QoS parameters in the subscription data stored in the UDM/UDR before the UE actually accesses the network. When a UE connects, the network function retrieves the pre-configured priority information and automatically applies the appropriate QoS parameters, eliminating the need for real-time complex decision-making and reducing system operational complexity.
2Ease of operation
If differentiated QoS parameters and priority levels are provided to different UEs, then user experience is enhanced, but network management complexity increases
Solution Approach 1:
The patent implements self-service by enabling the network to automatically retrieve and apply QoS parameters based on UE subscription information stored in the UDM/UDR. The system autonomously determines the appropriate priority level and applies corresponding QoS parameters without requiring manual network configuration or intervention, thereby enhancing user experience while keeping network management simple and automated.
Solution Approach 2:
The patent creates a universal framework where a single subscription-based mechanism serves multiple functions: it provides priority access control, QoS parameter allocation, resource scheduling guidance, and network slicing selection all through one integrated system. This multi-functionality approach enhances user experience across different services while avoiding the complexity of separate management systems for each function.
3Reliability
If subscription information is maintained and accessed by network functions, then secure operator control is achieved, but information management complexity increases
Solution Approach 1:
The patent introduces the UDM/UDR as an intermediary component that centralizes the storage and management of UE subscription information including priority levels and QoS parameters. Network functions access this information through standardized interfaces, which simplifies information management by providing a single source of truth while maintaining secure operator control. The intermediary handles the complexity of information management centrally, allowing individual network functions to remain simple.

AI summary
A system may maintain subscription information associated with a plurality of User Equipment (“UEs”), which may include priority level information, such as one or more access identities, associating a UE with one or more respective priority levels. The system may receive, from a network function (“NF”) of a wireless network, a request for priority level information associated with the UE, and may identify a particular set of priority levels indicated by the subscription information as being associated with the UE. The system may output the identified particular set of priority levels to the NF. The NF may maintain policy information associating the particular set of priority levels with one or more network parameters and may implement the one or more network parameters when providing service associated with the UE. The system may include a Unified Data Management function (“UDM”) or a Unified Data Repository (“UDR”) of the wireless network.
