    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. The present disclosure further relates to a method by a session management function (SMF) in a network including a session that is established via a first user plane function (UPF). The method includes determining whether to change the first UPF to a second UPF, and transmitting, to a terminal via an access and mobility function (AMF), a first message including a maintain time of the session established via the first UPF, when the first UPF needs to be changed.

    Abstract: A method for selecting an access network in a terminal of a mobile communication system according to one embodiment of the present specification comprises the steps of: if traffic is generated in the terminal, selecting an access network according to the characteristics of the generated traffic and network selection policy information; and transmitting and receiving the generated traffic via the selected access network. According to the embodiment, the present invention adjusts priorities of accesses given to users and applications in a wireless communication system including heterogenerous networks, thereby reducing processes for reselecting an access network of a user terminal, and reducing the cases of unnecessarily accessing a network having a low priority or requiring high costs for a long time. Therefore, the present invention can enhance user convenience and improve communication efficiency.

    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.
