摘要： The present disclosure relates to a 5G or 6G communication system for supporting a higher data transmission rate. A method for processing a multicast-broadcast service (MBS) session of a session management function (SMF) in a wireless communication system, according to one embodiment of the present disclosure, comprises the steps of: receiving, from an access and mobility management function (AMF), a first message requesting the update of a packet data unit (PDU) session related to the MBS session, if a terminal decides to leave the MBS session; and transmitting, to the AMF, a second message, which is a response to the update of the PDU session, in response to the first message.

摘要： A communication method of an access and mobility function (AMF) node in a communication system is provided. The communication method includes receiving, from a terminal via a base station, a first registration request message including a requested network slice selection assistance information, NSSAI; transmitting, to the terminal, a registration acceptance message for the first registration request message including an allowed NSSAI, and information on rejected single NSSAIs, S-NSSAIs, the information on rejected S-NSSAIs including a rejection cause for each of the rejected S-NSSAIs; and transmitting, to the terminal, a notify message including a new allowed NSSAI, in case that a state of the rejected single NSSAIs is changed.

摘要： A communication method of an access and mobility function (AMF) node in a wireless communication system is provided. The communication method includes receiving, from a terminal via a base station, a protocol data unit, PDU, session establishment request message including single-network slice selection assistance information, S-NSSAI. The AMF then transmits, to a network repository function, NRF, a discovery request message including the S-NSSAI and receives, from the NRF, a discovery response message including information on at least one session management function, SMF, and information on a network slice instance, NSI, identifier ID, corresponding to the S-NSSAI. The AMF then selects an SMF based on the information on the at least one SMF and the information on the NSI ID corresponding to the S-NSSAI; and transmits, to the SMF, a request message for creating a PDU session including the S-NSSAI.

摘要： The present disclosure relates to a communication method and system for converging a 5 th -Generation (5G) communication system for supporting higher data rates beyond a 4 th -Generation (4G) system with a technology for Internet of Things (IoT). The present disclosure may be applied to intelligent services based on the 5G communication technology and the IoT-related technology, such as smart home, smart building, smart city, smart car, connected car, health care, digital education, smart retail, security and safety services. According to one embodiment of the disclosure, terminal access is controlled or terminal access is permitted by using NAS protocol in a 5G communication, and thus a congested situation can be controlled.
