    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 a context message including a DNS message processing rule from an session management function (SMF), receiving a DNS query message from a user equipment (UE), transmitting the processed DNS query message to a DNS server based on the DNS message processing rule, receiving a DNS response message including an EAS internet protocol (IP) address from the DNS server, and transmitting the DNS response message to the UE based on the DNS message processing rule.

    Abstract: A method of a network function (NF) entity performing communication in a wireless communication system includes: in case that a first registration request of a user equipment (UE) for a slice is received at an access and mobility function (AMF) entity through a first network, receiving a first slice availability request message for the slice from the AMF entity; determining whether the slice is available for the UE, based on a network slice policy; and transmitting, to the AMF entity, a response message including information regarding slice availability of the UE according to the first registration request, wherein in case that a second registration request of the UE for the slice is received at the AMF entity through a second network, slice availability of the UE according to the second registration request is determined based on at least one of the network slice policy or the information regarding the slice availability of the UE according to the first registration request.

    Abstract: Disclosed is a method of transmitting/receiving a signal in a Mobile Management Entity (MME) of a mobile communication system, the method comprising: transmitting a subscriber information request message including information of a UE, to a Home Subscriber Server (HSS); receiving, from the HSS, a response message which corresponds to the request message and includes an indicator indicating whether it is possible to perform traffic offloading using a Wireless Local Area Network (WLAN) with regard to an Access Point Name (APN) connection or a Packet Data Network (PDN) connection of the UE; determining whether it is possible to perform the traffic offloading using the WLAN, on the basis of at least one of information included in the received response message and information configured in the MME; and; and transmitting, to the UE, a message including information on whether it is possible to perform the traffic offloading using the WLAN. A communication method according to an embodiment of the present specification can generate one or more PDN connections with regard to one APN when the UE accesses a PDN through the WLAN. Further, the communication method according to the present invention can effectively be subjected to a traffic offloading control by the eNB even when the UE is roaming.

    Abstract: The present disclosure relates to a communication method and system for converging a 5th-Generation (5G) communication system for supporting higher data rates beyond a 4th-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. The disclosure proposes, when a UE is registered in an AMF which does not support ATSSS (registration procedure), a method by which, an old AMF identifies the registration and releases an MA PDU session and a method by which the UE identifies the registration and releases the MA PDU session in a wireless communication system according to an embodiment.
