Abstract: A method and apparatus for managing mobility of a terminal by a first base station in a communication system. The first base station assigns a first address to the terminal located in a cell managed by the first base station and establishes a session to an external server that communicates with the terminal using the first address. If the terminal moves to a cell managed by a second base station different from the first base station, the first base station determines whether information about a second address assigned to the terminal by the second base station is received within a predetermined time. Upon receiving the information about the second address within the predetermined time, the first base station transmits data received from the external server to the terminal through the second base station using the information about the second address.

Abstract: The present invention relates to a 5G or pre-5G communication system for supporting high data throughput beyond the 4G communication systems such as LTE. A method for a server for supporting the mobility of a user equipment (UE) in a mobile communication network comprises the steps of: establishing an IP flow with the UE utilizing a first IP address to transceive data; receiving a message comprising a second IP address allocated to the UE and an identifier for the IP flow; generating a tunnel interface for communicating with the UE having the second IP address as the ending IP address, and binding the IP flow allocated to the identifier to the generated tunnel interface; and transceiving data with the UE by means of the tunnel interface.

Abstract: The present disclosure relates to a 5G or a pre-5G communication system to be provided in order to support a higher data transmission rate than a 4G communication system such as LTE. The present invention provides a method for receiving, by a terminal, a mobile end service in a communication system, the method including: a step of ascertaining whether there exists a continuously available service among services which have been provided from a serving base station, on the basis of a list of supported services received from a target base station; and in the case that there exists a continuously available service, a step of transmitting a service area update request to the target base station via a connection layer if the continuously available service supports a mobile end service.

Abstract: The present disclosure relates to a 5G or pre-5G communication system to be provided for supporting a data transmission rate higher than that of a 4G communication system such as an LTE. The present invention relates to a method by which a proxy sets an initial window value in a wireless communication system, the method comprising: splitting a transmission control protocol (TCP) connection between a terminal and a server; extracting the information related to the terminal from the data received from the terminal; and setting the initial window value on the basis of a round trip time (RTT) value and a throughput value for each of terminal groups grouped on the basis of the information related to the terminal.

Abstract: A method for transmitting a status report in a communication system based on multiple Radio Access Technologies (RATs) is provided. The method includes, when missing sequence numbers are detected from sequence numbers of packets stored in a reception buffer, identifying whether there are one or more sequence numbers which have not been received due to a transmission delay time difference between the multiple RATs in the missing sequence numbers, and when there are one or more sequence numbers in the missing sequence numbers, delaying transmission of the status report.
