    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.

    Abstract: The present disclosure relates to a communication technique of fusing a 5G communication system for supporting higher data transmission rate beyond a 4G system with an IoT technology and a system thereof, and provides an intelligent service based on the 5G communication technology and the IoT related technology. A method performed by an access network entity in a wireless communication system includes receiving, from a terminal in the wireless communication system, a first message including first information for identifying an AMF, the first information including an AMF set identifier and an AMF identifier; selecting an AMF set based on the AMF set identifier; selecting an AMF from the selected AMF set; and transmitting, to the terminal, a second message as a response to the first message. The AMF set includes a plurality of AMFs based on network slices the AMFs each support, and the AMF set identifier is an identifier of the AMF set, and the AMF identifier is an identifier of an AMF within the AMF set.

    Abstract: The disclosure relates to a communication technique and a system thereof for fusing, with IoT technology, a 5G communication system for supporting a higher data transmission rate than a 4G system. The disclosure may be applied to intelligent services (such as smart homes, smart buildings, smart cities, smart cars or connected cars, health care, digital education, retail business, and security and safety related services, etc.) on the basis of 5G communication technology and IoT related technology. The disclosure may provide a method for setting the monitoring of an application server (AS), the method comprising the steps of: transmitting, to a service capability exposure function (SCEF), a first message which comprises information on an identifier, which indicates a group including a plurality of terminals, and a waiting time and instructs to report monitoring information on the group including a plurality of terminals; and receiving, from the SCEF, a second message comprising the monitoring information on the group of a plurality of terminals.

    Abstract: The present disclosure relates to a communication technique for fusing, with IoT technology, a 5G communication system for supporting a higher data transmission rate than a 4G system, and a system thereof. The present disclosure may be applied to an intelligent service such as a smart home, a smart building, a smart city, a smart car or a connected car, health care, digital education, retail, and security and safety related services on the basis of 5G communication technologies and IoT related technologies. A method for performing a vehicle communication service by a first terminal in a wireless communication system, according to the present disclosure, may comprise the steps of: receiving a first message related to the vehicle communication service from a network entity; determining a parameter of the vehicle communication service on the basis of the first message; receiving a second message related to the vehicle communication service from a second terminal; and determining whether to process the second message on the basis of the parameter of the vehicle communication service.

    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.
