Title:
APPARATUS AND METHOD FOR SERVICE SUBSCRIPTION, USING E2 INTERFACE IN WIRELESS ACCESS NETWORK COMMUNICATION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2021/066588
Kind Code:
A1
Abstract:
The present disclosure relates to a 5th generation (5G) or pre-5G communication system for supporting a data transmission rate higher than that of a 4th generation (4G) communication system such as long term evolution (LTE). According to various embodiments of the present disclosure, a method performed by an E2 node comprises a step of receiving a RIC subscription request message from a radio access network (RAN) intelligent controller (RIC) through an E2 interface, wherein the RIC subscription request message includes information for indicating the type of network interface.
