Network Slice Quota Notification for UE Resource Allocation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems, particularly in LTE and emerging 5G networks, lack mechanisms to effectively notify user equipment (UE) about quota management for network slices, leading to inefficiencies in resource allocation and potential overloading.
Innovation Solution
Implementing a system where the Access and Mobility Management Function (AMF) and Session Management Function (SMF) inform UE devices about quota availability for requested network slices through specific message fields, allowing UE to make informed decisions on resource usage and access control.

Engineering Contradiction Analysis
1Productivity
If the network does not notify UE about slice quota availability, then the system remains simple and messages are short, but resource allocation efficiency deteriorates and network overload occurs
Solution Approach 1:
The quota management information is segmented into distinct fields within the NAS message structure. The First Indication Information field specifically indicates whether quota management is applied to a network slice, while the Second Indication Information field provides the actual quota availability. This segmentation allows the UE to process only the relevant portions of the message without being overwhelmed by the entire message structure.
Solution Approach 2:
The patent extracts the essential quota management information from the complex NAS message and presents it in a simplified, dedicated format. By taking out only the critical indicators (whether quota management is applied and the actual quota status), the system enables efficient UE decision-making without requiring the UE to parse and interpret the entire complex message structure.
2Productivity
If the network provides detailed quota information to UE, then resource allocation is optimized, but message size and processing complexity increase
Solution Approach 1:
The patent applies local quality by providing quota information specifically tailored to the network slice the UE is attempting to access. Rather than transmitting comprehensive quota data for all network slices, the system provides targeted information only for the relevant slice, reducing information overhead while maintaining optimal resource allocation for the specific access attempt.
3Reliability
If the UE makes informed decisions about resource usage, then network overload is prevented, but the UE must process additional information increasing computational load
Solution Approach 1:
The network performs preliminary action by providing quota management indicators and quota availability information to the UE before the UE attempts to access the network slice. This advance information allows the UE to make informed decisions about whether to proceed with network slice selection, preventing unnecessary access attempts and reducing the computational burden of processing failed connections.

AI summary
Apparatuses, systems, and methods for a network to notify user equipment device (UE) whether a network slice the UE has requested is subject to a quota. An AMF of the network may inform the UE if an allowed slice(s) is subject to quota management as part of a registration procedure via a registration accept and/or a UE configuration update command. In addition to providing information regarding whether an S-NSSAI is subject to quota management, the AMF may also share the percent of quota availability to the UE. The UE may implement access control logic based on the received available quota for a particular network slice.
