Abstract
A new cell specification procedure can be defined, in order to support more efficiently a network slice function in a new radio (NR) access technology as being a part of a 5G communication system. From a perspective of a radio access network (RAN)-core network (CN) interface, a RAN node can transmit, to a CN node, a first indicator related to the slice support of the RAN node, and receive, from the CN node, a second indicator related to the slice support of the CN node.

A method for a radio access network (RAN) node in a wireless communication system, the method comprising:
- transmitting, to a core network (CN) node, a RAN-CN interface setup request message including 1) a global identifier (ID) of the RAN node, and 2) information related to slice support of the RAN node;
- receiving, from the CN node, a RAN-CN interface setup response message including 1) identification information of the CN node, and 2) information related to slice support of the CN node;
- and
- setting up a RAN-CN interface between the RAN node and the CN node based on the RAN-CN interface setup request message and the RAN-CN interface setup response message.
A radio access network (RAN) node in a wireless communication system, comprising:
- at least one transceiver;
- at least processor;
- and
- at least one computer memory operably connectable to the at least one processor and storing instructions that, based on being executed by the at least one processor, performs operations comprising:
- transmitting, to a core network (CN) node, a RAN-CN interface setup request message including 1) a global identifier (ID) of the RAN node, and 2) information related to slice support of the RAN node;
- receiving, from the CN node, a RAN-CN interface setup response message including 1) identification information of the CN node, and 2) information related to slice support of the CN node;
- and
- setting up a RAN-CN interface between the RAN node and the CN node based on the RAN-CN interface setup request message and the RAN-CN interface setup response message.
