Network Slice Quota Management Function
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems lack efficient mechanisms for managing network slice capacity, leading to potential overloads and service disruptions due to the increasing demand for network resources from diverse devices and applications.
Innovation Solution
Deployment of a network slice quota management function within the cellular core network to track and manage capacity information for each network slice, allowing for the enforcement of quotas on the number of devices and sessions, enabling informed decision-making for resource allocation and preventing service overload.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If network slice capacity is increased to meet growing demand from diverse devices and applications, then service coverage and user capacity are improved, but network overload and service disruptions occur
Solution Approach 1:
The patent implements quota management that pre-defines capacity limits for network slices before overload occurs. The network slice quota management function proactively tracks and enforces quotas on the number of devices and sessions, preventing network overload before it happens by rejecting new registrations and sessions when quotas are approached, thus maintaining service stability while accommodating growing demand.
2Reliability
If network slice quotas are enforced to prevent overload, then service reliability is improved, but device complexity increases due to additional management functions
Solution Approach 1:
The patent introduces a network slice quota management function as an intermediary component that sits between the network slice and accessing devices. This dedicated management function handles all quota tracking, monitoring, and enforcement operations, isolating the complexity of quota management from other network components. The function provides standardized interfaces for querying and updating quotas, simplifying integration while ensuring reliable service through enforced capacity limits.

AI summary
Apparatuses, systems, and methods for performing network slice quota management. A network slice quota management function may store capacity information for one or more network slices. The network slice quota management function may receive a request for an indication of whether a network slice has additional capacity. The network slice quota management function may provide an indication of whether the network slice has additional capacity in response to the request. The capacity information may relate to the capacity of the network slice with respect to the number of wireless devices registered for the network slice, or to the capacity of the network slice with respect to the number of packet sessions established with the network slice, or both, among various possibilities.
