APPARATUS AND METHOD FOR E2 NODE CONTROL AND CELL CONTROL IN WIRELESS COMMUNICATION SYSTEM

According to an embodiment of the present disclosure, a method performed by a Distributed Unit (DU) (e.g., included in a 5G or 6G system) may comprise the steps of: receiving a control message from a Radio Access Network (RAN) Intelligent Controller (RIC), the control message comprising control information for controlling a Data Radio Bearer (DRB) allocation in each network slice; identifying single network slice selection assistance information (S-NSSAI) of the one or more DRBs from a request message for configuring the one or more DRBs of the terminal; and configuring the number of distributable DRBs in the network slice corresponding to the S-NSSAI based on the control information. 根据本公开的实施例，一种由分布式单元(DU)(例如，包括在5G或6G系统中)执行的方法可以包括以下步骤：从无线电接入网络(RAN)智能控制器(RIC)接收控制消息，该控制消息包括用于控制每个网络切片中的数据无线电承载(DRB)分配的控制信息；从用于配置终端的一个或多个DRB的请求消息中识别一个或多个DRB的单网络切片选择辅助信息(S-NSSAI)；以及基于控制信息，配置与S-NSSAI相对应的网络切片中可分配的DRB的数量。
