Telia Co has filed a patent for a method and network device for network slicing. The method involves receiving a request from a terminal device to reserve or assign a network slice for an application. The device then determines if the application is known by matching it against a database of application profiles and identities. If known, a cost is provided for setting up or assigning a network slice. If unknown, a profile is assigned and a default network slice is configured and assigned to the application.

A recently filed patent (Publication Number: US20230283569A1) describes a method and network device for network slicing. Network slicing is a technique used in telecommunications networks to create virtual networks that are tailored to specific applications or services.

The method involves receiving a request from a terminal device to reserve or assign a network slice for an application. The network device then determines whether the application is previously known by matching it against a database of application profiles and identities. If the application is known, the network device provides a cost for setting up or assigning a network slice for the application. If the application is unknown, the network device assigns a profile to the application and configures or assigns a default network slice to it.

In addition, if the application is determined to be unknown, the method may involve analyzing the connection pattern of the application to determine its characteristics before assigning a profile to it. The connection pattern of the application can be monitored, and if the behavior of the application remains consistent, it can be defined as profile ready for configuring or assigning a default network slice.

The method also includes determining the cost for allocating the resources and capabilities required by the application. The terminal device is informed of the cost for supporting the usage of the application and is requested to confirm or acknowledge the cost. If no confirmation or acknowledgement is received within a predetermined time interval, the allocation of required resources associated with the network slice may be denied.

The request from the terminal device includes a declaration specifying the application profile and required resources for the network slice. The declaration may include application characteristics such as bandwidth, throughput, latency, jitter, and error rate.

The network device described in the patent includes a processor and memory containing instructions for executing the method. It receives requests from terminal devices, determines the known or unknown status of the application, provides cost information, and assigns profiles and network slices accordingly.

Overall, this patent describes a method and network device that enable efficient network slicing by determining the known or unknown status of applications, assigning profiles and network slices, and providing cost information to terminal devices. This technology has the potential to enhance the customization and optimization of telecommunications networks for different applications and services.
