Enterprise Network Slice Auto Switching Controller
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Managing network slices in 5G networks efficiently to meet varying service quality requirements across different locations and scenarios, such as IoT devices, is challenging due to the need for adaptive and optimized resource utilization, especially in scenarios like mining, emergency responses, and live events, where consistent Quality of Service (QoS) is critical.
Innovation Solution
Implementing a method for switching devices to federated network slices based on pre-configured rules by a controller that monitors device parameters and selects the best available network slice across multiple operators based on location, time, and QoS parameters, using a Communication Service Management Function (CSMF) that synchronizes network slice repositories and manages rule-based switching.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual network slice management is used, then operational control is maintained, but service quality consistency across locations deteriorates and management efficiency decreases
Solution Approach 1:
The system implements automated self-service through the CSMF controller that autonomously monitors device parameters, evaluates network slice conditions, and performs switching operations based on pre-configured rules without requiring manual intervention, thereby maintaining service quality consistency while improving management efficiency
Solution Approach 2:
The system applies preliminary action by pre-configuring switching rules and criteria in advance through the CSMF controller, so that when triggering events occur, the network slice switching can be executed immediately without manual intervention, ensuring both service quality consistency and operational efficiency
2Adaptability or versatility
If static network slice assignment is used, then configuration simplicity is maintained, but adaptability to different locations and scenarios deteriorates
Solution Approach 1:
The system implements dynamics by enabling the CSMF controller to dynamically monitor device parameters such as location, time, and network conditions, and automatically switch network slices based on real-time triggering events, thereby achieving adaptability to different locations and scenarios while managing complexity through automated rule-based control
Solution Approach 2:
The system applies parameter changes by using the CSMF controller to monitor and respond to changes in device parameters (location, time, network conditions), automatically selecting appropriate network slices based on pre-configured rules that define parameter thresholds and switching criteria
3Productivity
If multiple network slices are managed manually, then service quality can be optimized, but time consumption and operational overhead increase
Solution Approach 1:
The system implements feedback through the CSMF controller that continuously monitors device parameters and network slice conditions, automatically triggering switching operations when pre-configured rules are met, thereby optimizing resource utilization efficiency while eliminating time-consuming manual management through closed-loop automated control

AI summary
A method in which an enterprise switches its devices to various federated network slices across operators based on cost, time, quality, and/or availability parameters defined in flexible rules managed by the enterprise. The method includes obtaining, by a controller of an enterprise, one or more parameters of a device served by a network slice of a core network. The method further includes, based on the one or more parameters of the device and one or more rules, determining, by the controller, whether a triggering event associated with a slice reselection occurred and based on the triggering event and the one or more rules, selecting, by the controller, a federated network slice from among a plurality of network slices provided by a plurality of core networks. The method further includes the controller causing the device to switch from the network slice to the federated network slice.
