    Abstract: A communication method and apparatus is provided for enhancing video telephony service quality by protecting against call setup failure or service quality degradation caused due to switching of the User Equipment (UE) to a network which does not fulfill the data rate required for video telephony in the video call setup process. The communication method of a terminal in a mobile communication system according to the present disclosure includes transmitting a video telephony call setup request message, receiving a switching command for Circuit Switched Fall Back (CSFB), and setting, if the switching command includes a target cell type set to the 2nd Generation (2G) cell and if a 3rd Generation (3G) cell to which the terminal can access exists, up the video telephony call by switching a connection to the 3G cell.

    Abstract: Provided are a discovery method and apparatus. A communication method for a user equipment (UE) may include: receiving first resource information indicating a first resource region and second resource information indicating a second resource region from an evolved Node B (eNB); receiving a first message from a second UE via the first resource region; checking whether the contents of the first message match the UE; and sending, when the contents of the first message match the UE, a second message associated with the first message to the second UE via the second resource region. A user equipment (UE) may include: a communication unit configured to receive first resource information indicating a first resource region and second resource information indicating a second resource region from an evolved Node B (eNB), and receive a first message from a second UE via the first resource region; and a control unit configured to check whether the contents of the first message match the UE.

    Abstract: The disclosure relates to a communication technique for converging, with an IoT technology, a 5G communication system for supporting a higher data transmission rate than a 4G system, and a system therefor. 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 businesses, and security and safety related services, on the basis of 5G communications technologies and IoT-related technologies. A method for operating relay UE in a mobile communication system includes transmitting, to a network node connected to the relay UE, a remote UE report message including remote UE information about a remote UE accessing a network via the relay UE, wherein the remote UE information includes IP address information allocated to the remote UE; starting a timer upon transmitting the remote UE report message to the network node; receiving, from the network node, a response message in reply to the remote UE report message; and stopping the timer upon receipt of the response message from the network node. the IP address information includes an IP address and port information of the remote UE in case that IPv4 is used as an address type.

    Abstract: Disclosed are: a communication method for incorporating an IoT technique with a 5G communication system for supporting a higher data transmission rate than that of a 4G system or a subsequent system; and a system therefor. The present invention can be applied to intelligent services (for example, services related to smart homes, smart buildings, smart cities, smart cars or connected cars, health care, digital education, retail business, security, safety, and the like) on the basis of a 5G communication technique and IoT-related techniques. A communication method and device of the base station and network equipment in the mobile communication system, according to the present invention, can quickly provide, to the base station to which the terminal moves, a D2D service authorized indication of the terminal for a PLMN provided from the base station of a region to which the terminal moves, even though the terminal moves to the region at which the different PLMNs are provided, and can allow the terminal to endlessly use the services, since the terminal is allocated with the resources for the D2D services during the movement thereof.

    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.
    Methods and apparatuses provide a service to user equipment through a dedicated core network. In one method, a base station, also referred to as eNB, receives a non-access stratum (NAS) message from user equipment (UE), and transmits a first initial UE message having the NAS message to a first mobility management entity (MME). Also, the base station receives a redirection request message having the NAS message from the first MME, and transmits a second initial UE message having the NAS message to a second MME. In another method, the MME receives the first initial UE message having the NAS message from the base station, and transmits the redirection request message having the NAS message when the MME fails to support a dedicated core network according to UE usage type information. If the redirection request message is transmitted, a second initial UE message having the NAS message is transmitted to a dedicated MME.
