Abstract: The present disclosure relates to a 5G or pre-5G communication system for supporting a data transmission rate higher than that of a 4G communication system such as LTE. According to one embodiment of the present invention, a method in a roaming environment supporting a network slice is provided. The method comprises the steps of: receiving, from a terminal, a first packet data unit (PDU) session request message including slice assistance information indicating the properties of a service the terminal intends to use; transmitting, to a network function (NF) repository function, a first discovery request message including a home public land mobile network (PLMN) ID of the terminal and the slice assistance information; and receiving, from the NF repository function, a first discovery response message including a session management network function (SM NF) address of the home PLMN. The SM NF is selected on the basis of the slice assistance information.

Abstract: A method for Xn handover of a multicast/broadcast service (MBS) by a session management function (SMF) device in a mobile communication system is provided. The method includes receiving, from a target next generation radio access network (NG-RAN) node through an access and mobility management function (AMF), a first message including information on whether the target NG-RAN node supports the MBS, determining an individual delivery method for MBS data, in case that the target NG-RAN node does not support the MBS based on the first message, and setting up the MBS data to be individually delivered to a user equipment (UE) through the target NG-RAN node.

Abstract: The present disclosure relates to a communication technique for converging an IoT technology with a 5G communication system for supporting a higher data transfer rate beyond a 4G system, and a system therefor. The present disclosure can be applied to an intelligent service (e.g. a smart home, a smart building, a smart city, a smart car or connected car, healthcare, digital education, a retail business, a security and safety-related service, etc.) on the basis of a 5G communication technology and an IoT-related technology. The present disclosure provides a method wherein, after a MICO mode terminal establishes a connection and transmits data, the MICO mode terminal can be kept in a connected mode state, rather than entering an idle mode, in order to provide for a case where slightly delayed response traffic occurs according to the type of application or service.

Abstract: A method performed by a first entity in a wireless communication system is provided. The method includes receiving a first request message for receiving a multicast service from a second entity, detecting information about a multicast session identifier (ID) from the first request message, requesting information about a fourth entity corresponding to the multicast session ID from a third entity when the first entity does not correspond to the information about the multicast session ID, receiving the information about the fourth entity corresponding to the multicast session ID, identifying the fourth entity based on the information about the fourth entity, transmitting a multicast session join request message to the fourth entity, and receiving a message accepting multicast session join from the fourth entity.
