    Abstract: The disclosure relates to a 5G or 6G communication system for supporting a higher data transmission rate. According to an embodiment of the disclosure, a method of controlling multicast and broadcast service (MBS) by a session management function (SMF) in a wireless communication system includes transmitting a first message including information about an MBS area and an MBS session identifier (ID) to an access and mobility management function (AMF), receiving a second message indicating that a user equipment receiving a service within the MBS area is located outside the MBS area from the AMF, determining that the UE is located outside the MBS area based on the second message, and processing a quality of service (QoS) flow applied to MBS traffic delivered by individual delivery.

    Abstract: The disclosure relates to a 5th generation (5G) communication system communication scheme and a system thereof to support a higher data rate than that of the 4th generation (4G) system. A method performed by an edge application server discover function (EASDF) to discover an edge application server (EAS) is provided. The method includes receiving EAS domain configuration information including an enhanced domain name system (DNS) client subnet (ECS) option from an edge application service domain repository (EDR), receiving a protocol data unit (PDU) session state report message including a DNS message processing rule from an session management function (SMF), receiving a DNS query message from a user equipment (UE), processing the DNS query message based on the EAS domain configuration information and the PDU session state report message, transmitting the processed DNS query message to a DNS server, receiving a DNS response message including an EAS internet protocol (IP) address from the DNS server in response to the processed DNS query message, and transmitting the DNS response message to the UE.

    Abstract: The present disclosure relates to a method and device for providing an edge computing service to a user equipment (UE) in a communication system, and more particularly, to a method and device for managing an identifier of a wireless communication UE so as to provide an edge computing service to the UE. A method according to an embodiment of the present disclosure is a method for managing an identifier of a UE in an edge enabler server of an edge computing system, and the method may comprise the operations of: receiving a first message via a mobile communication network from a UE of a mobile communication system, wherein the first message includes a generic public subscription identifier (GPSI) of the UE, and the received identifier of the UE identifies validity on the basis of a previously received profile of the UE; if the identifier of the UE is valid, binding and storing the identifier of the UE and a UE IP address based on the received first message; and if the identifier of the UE is valid, transmitting a first response message to the UE.

    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). According to various embodiments of the disclosure, an operating method of a user plane function (UPF) in a wireless communication system and an apparatus therefor are provided. The operating method includes receiving a first parameter for clock synchronization from a base station, and performing the clock synchronization with a neighboring network system using the received first parameter and a second parameter. The first parameter may include information relating to a link delay time between the neighboring network system and a network system comprising the UPF, and a residence time of a terminal, a base station and the UPF of the network system comprising the UPF, and the second parameter may include information relating to a backhaul delay time between the base station and the UPF.

    Abstract: A communication method and system converges a 5G communication system for supporting higher data rates beyond a 4G system with an IoT technology. The system and method 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. Embodiments provide a scheme for efficiently operating an UP connection of a session in case where a terminal has a plurality of sessions in a mobile communication system, such as a 5G system, having a network structure in which an AMF for mobility management and an SMF for session management are separated from each other. A terminal (UE) can optimize a non-access stratum (NAS) signaling message, and can perform data transmission/reception with low latency.
