## Abstract

A method comprising: obtaining, at a user equipment, information on a cell network slice support; determining, for the user equipment a network slice; and selecting one cell supporting the determined network slice based on the information.

## Claims

### Claim 1

A method, comprising:
obtaining, at a user equipment, information on cell network slice support;
determining, for the user equipment, a network slice; and
selecting one cell supporting the determined network slice based on the information;
wherein the obtaining, at the user equipment, information on cell network slice support comprises receiving a network slice group mapping from a core node,
wherein the obtaining, at the user equipment, information on cell network slice support comprises receiving, from the core node, a list of frequency bands supported by at least one group from the network slice group mapping.

### Claim 2 (depends on 1)

The method as claimed in claim 1, wherein the list of frequency bands supported by the at least one group from the network slice group mapping is identified based on a radio access technology frequency selection priority identifier.

### Claim 3 (depends on 1)

The method as claimed in claim 1, wherein the cell comprise one of:
a Next-Generation Radio Access Network cell;
an Evolved-Universal Mobile Telecommunications Service Terrestrial Radio Access Network cell;
an Universal Mobile Telecommunications Service Radio Access Network cell; and
a Wi-fi network cell.

### Claim 4

A method, comprising:
generating, information on cell network slice support; and
transmitting to a user equipment the information on cell network slice support, wherein the user equipment is configured to determine a network slice and select one cell supporting the determined network slice based on the information,
wherein the information comprises at least one of:
a network slice group mapping;
a list of frequency bands supported by at least one group from the network slice group mapping; and
radio access technology frequency selection priority identifiers supported by a network slice.
