    Abstract: 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.

    Abstract: The present invention relates to a method and a device for barring access of terminals connected to a base station. A communication method of an Internet protocol multimedia service (IMS) entity, according to one embodiment of the present invention, comprises the steps of: receiving a service request message from a terminal; determining whether to allow an access of a service according to a load status of the IMS and the service requested from the terminal; and transmitting, to the terminal, a connection barring message which includes information for indicating that the access of the terminal is barred, when it is determined to bar the access of the service. According to the one embodiment of the present invention, the IMS can be prevented from being congested due to loads concentrated on IMS entities such as a P-CSCF and the like, and can prevent a situation in which an emergency call or a priority call of a person from a police station or a fire station or the like cannot be received.
