摘要： The present disclosure relates to a communication technique for combining a 5G communication system for supporting a higher data transmission rate after a 4G system with IoT technology, and a system thereof. The present disclosure can be applied to an intelligent service (for example, smart home, smart building, smart city, smart car or connected car, health care, digital education, retail business, security and safety-related service, and so on) on the basis of 5G communication technology and IoT related technology. The present disclosure can provide a method for supporting a handover and a base station performing the same. The method includes receiving a message including a Radio Link Failure (RLF) report for a terminal from at least another base station, and determining whether a cell in which an RRC connection reestablishment has been attempted by the terminal after the RLF is a cell that is suitable to serve the terminal at a time of RLF occurrence on the basis of at least one of RRC connection setup indicator information and the RLF report.

摘要： The present invention relates to a public warning system (PWS) in a mobile Communication network, and the present invention relates to a method and an apparatus for resolving a security problem occurring in the PWS with a protocol and actions between other network entities, and managing same. A user equipment (UE), according to the present invention, saves a public key and a public key index pair of a cell broadcast center (CBC), verifies the CBC which has transmitted a digital signature when the digital signature is received from a subject that transmits a public warning, and resolves a security problem related to a public security system so as to receive a message by the public warning system. As a result, according to the present invention, when the public warning message is received in environments such as an evolved universal terrestrial radio access network (EUTRAN), a universal terrestrial radio access network (UTRAN), or a GSM/EDGE radio access network (GERAN), the subject that has sent the public warning message is verified by the user equipment, thereby enabling the user equipment to perform an action appropriate to the warning message in an emergency disaster situation.

摘要： 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 method for transmitting and receiving a signal by a base station in a mobile communication system comprises the steps of: receiving a handover request message including a first information related to a device-to-device (D2D) service for a handover target terminal; and allocating D2D resources to the terminal based on the handover request message. 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.
