Abstract: A method and apparatus for performing a terminal trace in a wireless communication system is disclosed. A control method for a femto base station according to an embodiment of the present invention may comprise the steps of: after a terminal is handed over to the femto base station, receiving terminal trace activation information from a serving base station; and transmitting a message including the received terminal trace activation information to a femto gateway (HeNB gateway) so as to allow the femto gateway to trace the terminal.

Abstract: The present disclosure relates to a communication method and system for converging a 5 th-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.A method for a base station to perform communication in a wireless communication system includes transmitting an interface setup request message related to tracking area information to at least one mobility management entity (MME) in a first MME pool. The method includes identifying whether an interface setup response message related to the tracking area information is received from the at least one MME in the first MME pool, and storing mapping information between the tracking area information and the first MME pool if the interface setup response message is received.

Abstract: Disclosed are a communication technique for merging, with IoT technology, a 5G communication system for supporting a data transmission rate higher than that of a 4G system; and a system therefor. The present disclosure can be applied to intelligent services (for example, smart home, smart building, smart city, smart car or connected car, healthcare, digital education, retail business, security and safety related services, and the like) on the basis of 5G communication technology and IoT related technologies. The present disclosure relates to a method by which a terminal receives a circuit switching (CS) service, and according to the present disclosure, the method by which a terminal receives a CS service, comprises the steps of: transmitting a CS fallback (CSFB) request to a mobility management entity (MME) through a first base station in order to use the CS service; detecting the failure of a radio resource connection to the first base station; and transmitting, to a second base station, a radio resource re-establishment related message including a CSFB indicator for identifying the CSFB request.
