MUD-Based Network Slice Assignment for Wireless IoT Sessions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current network slicing technologies in 3GPP mobile networks struggle to efficiently manage and connect wireless IoT devices to appropriate network slices due to limited use of Manufacturer Usage Description (MUD) parameters, which are primarily utilized for network security configurations rather than slice provisioning.
Innovation Solution
The integration of MUD parameters is extended to support 3GPP mobile network slice mappings by using usage description objects to profile wireless devices, determine their appropriate network slices, and facilitate the transition of their sessions from onboarding slices to the correct network slices based on security and communication requirements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If MUD parameters are used only for network security configurations, then network security is improved, but network slice assignment capability deteriorates
Solution Approach 1:
The patent extends the usage of MUD parameters from solely security configuration to dual-purpose usage, enabling them to serve both network security functions and network slice assignment functions. The network slice selection assistance information (S-NSSAI) is configured to include MUD parameters, allowing a single parameter set to fulfill multiple roles in the 3GPP mobile network architecture.
2Adaptability or versatility
If network slicing architecture is introduced, then network service differentiation is improved, but network management complexity increases
Solution Approach 1:
The patent modifies the existing network slice selection parameters by incorporating MUD parameters into the S-NSSAI configuration. This parameter enhancement allows the network to automatically determine appropriate slices based on device usage descriptions, reducing manual configuration complexity while maintaining service differentiation capabilities.
3Measurement precision
If MUD parameters are integrated into network slice selection, then network slice assignment accuracy is improved, but system complexity increases
Solution Approach 1:
The patent introduces the S-NSSAI as an intermediary structure that bridges MUD parameters and network slice selection. By configuring S-NSSAI to include MUD parameters, the system creates a standardized interface that simplifies the integration process and reduces direct system complexity while improving assignment accuracy through precise device profiling.

AI summary
Provided herein are techniques to facilitate slice assignment for a wireless device based on Manufacturer Usage Description (MUD) parameters associated with the wireless device. In one instance, a method may include obtaining, by a provisioning server of a mobile network, a usage description object for a wireless device that has a session via an onboarding network slice of the mobile network in which the usage description object comprises usage parameters associated with the wireless device. The method may further include identifying, based on the usage parameters associated with the wireless device, a particular network slice that is to host the session for the wireless device and causing the session of the wireless device to be moved from the onboarding network slice to the particular network slice.
