Title:
ELECOTRNIC DEVICE AND METHOD FOR E2 RETENTION IN COMMUNICATION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2023/048517
Kind Code:
A1
Abstract:
According to various embodiments, E2 node comprises at least one transceiver and at least one processor operably coupled to the at least one transceiver. The at least one processor is configured to control the at least one transceiver to transmit, to a near-real time (Near-RT) radio access network (RAN) intelligent controller (RIC) via an E2 interface, a E2 setup request message including E2 retention information. The at least one processor is configured to control the at least one transceiver to receive, from the Near-RT RIC via the E2 interface, a E2 setup response message in response to the E2 setup request message including E2 retention indication.
