Abstract: Provided is a method of establishing a session for communication with a local network in a wireless communication system, the method including obtaining a request for using an integrated mode in which a user plane entity of a base station uses an integrated user plane entity that performs an operation of a user plane function (UPF) together, when a session between a local network and a user equipment (UE) is established, determining based on user information of the UE whether to accept use of an integrated mode, selecting the integrated user plane entity as a user plane entity in which the session is to be established, based on a result of the determining, and transmitting a session establishment request to the selected integrated user plane entity.

Abstract: Provided are a method and apparatus for managing a session in a wireless communication system. The method includes identifying a session management module with a failure from among a plurality of session management modules that each manage at least one session; determining a substitute module that replaces the session management module with the failure; obtaining, from a control plane entity, information about at least one session managed by the session management module with the failure; and controlling the substitute module to manage the at least one session, based on the obtained information about the at least one session.

Abstract: The present disclosure provides methods and apparatuses for transmitting data, by a base station, in an unlicensed frequency. A method according to a representative embodiment includes: transmitting a first signal for determining whether a data transmission is possible in an unlicensed frequency band; transmitting a second signal for reserving a data transmission in the unlicensed frequency band when the data transmission in the unlicensed frequency band is possible; and transmitting first data to a terminal through the unlicensed frequency band after transmitting the second signal. In an aspect, the base station determines whether other communication devices do not use the unlicensed frequency band, and transmits a channel reservation signal having a period shorter than a resource allocation period during a predetermined period of time, thereby pursuing coexistence with other communication devices and improving the performance of a communication system at the same time.

Abstract: The present disclosure relates to a pre-5th-Generation (5G) or 5G communication system to be provided for supporting higher data rates beyond 4th-Generation (4G) communication system such as long-term evolution (LTE). Disclosed is radio access technology (RAT) switching in a wireless communication system, and an operating method of a server for managing a session comprises the steps of: receiving information related to a determination on the switching of a RAT; determining, on the basis of the information, whether the RAT for providing a service to a terminal is switched from a first RAT to a second RAT; and transmitting, to an object for processing a user plan, a message indicating that a data route of the terminal will be switched from the first RAT to the second RAT.

Abstract: A method of a first terminal is provided. The method includes communicating with a first gateway by using a first internet protocol (IP) address allocated to the first terminal, according to a first IP session, in response to a distance between the first terminal and a second gateway being equal to or less than a predetermined threshold, establishing a second IP session with the second gateway while the first IP session is set in the first terminal, receiving, from a second terminal, a first IP session-release message about the first IP session via the second gateway by using a second IP address according to the second IP session, when data from the first terminal is received by the second terminal according to the first IP session, and in response to the first IP session-release message being received from the second gateway, releasing the first IP session with the first gateway.
