Method and apparatus for performing cell specific procedure or mobility procedure for network slice-based nr in wireless communication system

Abstract

A new cell specific procedure and/or a mobility procedure may be defined to more efficiently support a network slice function in new radio access technology (NR), which is a part of a 5G communication system. In terms of a radio access network (RAN) -RAN interface, the cell specific procedure comprises that a first RAN node transmits a first indicator related with the slice support of the first RAN node to a second RAN node, and receives from the second RAN node a second indicator related with the slice support of the first RAN node. The mobility procedure comprises that a target RAN node transmits a path change request message including slice-related information to a core network (CN) node, and receives from the CN node a path change response message including at least one of a common control plane function (C-CPF) identifier (ID), a finally selected slice-related ID or U-Plane information.
