NETWORK SLICE SELECTION - A simplified explanation of the abstract

This abstract first appeared for US patent application 18403160 titled 'NETWORK SLICE SELECTION

Simplified Explanation

The patent application describes a method for dynamic network slice selection, where a network slice is assigned to a user equipment (UE) based on specific parameters affecting the selection process.

• An AMF receives a UE request (registration or session) and transmits it to a PC_NSS.
• The PC_NSS determines selection data specifying UE-specific parameters for network slice selection.
• A network slice selector selects a network slice for the UE based on the selection data and transmits it to the AMF.
• The AMF controls the assignment of the network slice to the UE based on the received data and routing rule.

Potential Applications

This technology can be applied in:

• 5G networks
• Mobile communication systems
• Network slicing for different services

Problems Solved

• Efficient network slice selection
• Improved user experience
• Better resource allocation

Benefits

• Enhanced network performance
• Customized network slices for users
• Optimal resource utilization

Potential Commercial Applications

• Telecommunication companies
• Network equipment manufacturers
• IoT service providers

Possible Prior Art

One possible prior art could be the use of network slicing in 4G LTE networks for resource allocation and quality of service management.

Original Abstract Submitted

Network nodes and methods for control thereof for dynamic network slice selection. An AMF receives a UE request originating from the UE, the UE request being any one of a registration request and a session request. A network slice requester controls a transmitter to transmit a network slice selection request to a PC_NSS. A selection data manager of the PC_NSS determines selection data specifying one or more UE specific parameters affecting network slice selection. A network slice selector selects a network slice assignable for the UE, based on the selection data, determines network slice data and a corresponding network slice routing rule, and transmits them to the AMF. A network slice manager of the AMF controls assignment of a network slice to the UE in dependence on the received network slice data and network slice routing rule.
