    Abstract: The present disclosure relates to a communication technique of fusing a 5G communication system for supporting higher data transmission rate beyond a 4G system with an IoT technology and a system thereof, and provides 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, or the like) based on the 5G communication technology and the IoT related technology. A method for appropriately finding a network node providing services that user equipment (UE) wants in a 5G mobile communication system when a user initially accesses a G network includes a method for managing network deployment information and a method for transmitting an initial access request message with a detailed proposal technology. In addition, even when the service provided to the user equipment is modified after the initial access, a network node providing the corresponding service may be found in a similar manner.

    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.

    Abstract: Provided is a method and apparatus for device-to-device (D2D) communication, and, particularly, a method and apparatus for device-to-device (D2D) communication for discovering an adjacent UE through a network in a wireless cellular communication system. Provided are a method for performing device-to-device communication by a UE, and an apparatus therefor, the method including: transmitting a discovery request for discovering an adjacent UE to a server; scanning a discovery channel during a scanning time according to the discovery request; and performing the device-to-device communication with a discovered adjacent UE when the adjacent UE is discovered as a result of the scanning, wherein the discovery request is used for the server to transmit an announcement request to the adjacent UE corresponding to the discovery request, and the announcement indication information includes information which allows the adjacent UE to broadcast a discovery signal through the discovery channel during the scanning time.

    Abstract: A method of establishing a bearer in a packet switched mobile wireless communications network comprising a mobile device and a network node, and a corresponding network. A predetermined maximum number of bearers can be established for the mobile device within the network. Bearer information can be sent indicating the predetermined maximum number of bearers, a remaining number of bearers, or that no more bearers can be established. If no more bearers can be established and a further bearer is required a bearer previously established for the mobile device within the network can be released and if required a bearer synchronization procedure can be performed. A further bearer for the mobile device within the network can then be established. Alternatively, if the mobile device determines that an emergency PDN connection is required, it can send a request for a further bearer to the network node. If a current number of bearers established for the mobile device is equal to the maximum number of bearers, the network node can release a previously established bearer establish a bearer for an emergency PDN connection.
