Abstract: A communication method for incorporating an IoT technique with a 5G communication system for supporting a higher data transmission rate in comparison with a 4G system and subsequent systems and a system therefor are disclosed. 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, and safety) on the basis of a 5G communication technique and IoT-related techniques. A method for transmitting and receiving a signal in a terminal of a mobile communication system, according to one embodiment of the present specification, comprises the steps of establishing an access for a specific PDN connection with a base station and a wireless local area network (WLAN); detecting that the access through the WLAN is unusable; and transmitting, to a mobility management entity (MME), a control message for moving traffic through the WLAN, through the base station. According to one embodiment of the present specification, a traffic transmission path of the terminal capable of accessing both a 3GPP network and a non-3GPP network can be controlled in the network and the traffic transmission path can be determined according the states of the network and the terminal, thereby effectively utilizing limited communication resources.

Abstract: Various communication techniques and related systems for a fusion between a 5th generation (5G) communication system and Internet of Things (IoT) technology are provided. A user equipment (UE) is required to select a dedicated core network so as to receive a suitable service. In a method for transmitting and receiving a signal, an enhanced Node B (eNB) of a mobile communication system transmits a first request message to a first mobile management entity (MME), receives a reroute command message based on the first request message from the first MME, and transmits a second message to a second MME based on the reroute command message. Herein, the reroute command message contains the first request message, at least one MME identifier, and a UE identifier.

Abstract: The present invention relates to a method and an apparatus for transmitting data to user equipment through not only a current base station cell but also a neighboring base station cell via inter-eNB CA in a wireless communication system. A method for transmitting data though carrier aggregation in the wireless communication system, according to the present invention, comprises the steps of: a first base station transreceiving data with a terminal through at least two PDN connections; the first base station transmitting a carrier aggregation request message to a second base station for aggregating carriers, when the first base station determines to carry out inter-eNB carrier aggregation; the first base station receiving a carrier aggregation reply message from the second base station in response to the carrier aggregation request message; the first base station performing an RRC reconfiguration process with the terminal to notify to the terminal of the determination to perform the inter-eNB carrier aggregation; and the first base station transmitting a path change request message to a mobile management entity to correct a data transreceiving path, so that data on at least one PDN connection from among the PDN connections is transreceived through the second base station.
