Cell reselection method

A user equipment comprising

• a receiver configured to receive from a network node, slice non-supporting cell information indicating presence of a cell not supporting a network slice in a frequency comprised in slice frequency information indicating a correspondence relationship between the network slice, the frequency, and a frequency priority, and
• a controller configured to perform slice-specific cell reselection, based on the slice non-supporting cell information.

A cell reselection method in a mobile communication system, the cell reselection method comprising the steps of:

• transmitting, by a network node, slice support status information indicating whether network slices supported by cells are all identical in a predetermined range larger than a cell range;
• and
• performing, by a user equipment, slice-specific cell reselection, based on the slice support status information.
