Abstract: The present disclosure relates to a 5th generation (5G) or pre-5G communication system for supporting a higher data transmission rate beyond a 4th generation (4G) communication system such as long-term evolution (LTE). The present disclosure relates to beam management in a wireless communication system, and an operation method of a base station may comprise the steps of: transmitting first type reference signals; receiving feedback information on the first type reference signals; transmitting information on resources for second type reference signals, which are allocated on the basis of the feedback information, to at least one terminal; and transmitting the second type reference signals through the resources, wherein the second type reference signals are transmitted using fixed transmission beams by the base station. The present research has been conducted with the support of the “cross-departmental giga KOREA project” of the government (the ministry of science and ICT) in 2017 (No. GK17N0100, Development for mmWave-based 5G mobile communication system).

Abstract: Provided are a method and apparatus for managing a session in a wireless communication system. The method includes identifying a session management module with a failure from among a plurality of session management modules that each manage at least one session; determining a substitute module that replaces the session management module with the failure; obtaining, from a control plane entity, information about at least one session managed by the session management module with the failure; and controlling the substitute module to manage the at least one session, based on the obtained information about the at least one session.

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. A method of a proxy device in a communication system of the present disclosure includes identifying a packet loss rate on a wireless connection between a terminal and a server, determining whether the packet loss rate is greater than a predetermined threshold value, and proxying, if the packet loss rate is greater than the threshold value, the connection between the terminal and the server.

Abstract: The present disclosure relates to a pre-5th-Generation (5G) or 5G communication system to be provided for supporting higher data rates Beyond 4th-Generation (4G) communication system such as Long Term Evolution (LTE). The present disclosure is to provide a multicast service in a wireless communication system and comprises the steps of: receiving a multicast group participation message transmitted from a terminal via a communication session from a terminal to a first network entity; generating a multicast tunnel generation request message on the basis of the multicast group participation message, and transmitting the same to the first network entity; and generating a multicast service request message on the basis of the multicast group participation message, and transmitting the same to a second network entity. The present research is research that has been conducted with the support of the “Cross-Departmental Giga KOREA Project” funded by the government (the Ministry of Science and ICT) in 2017 (No. GK17N0100, millimeter wave 5G mobile communication system development).

Abstract: A method of a first terminal is provided. The method includes communicating with a first gateway by using a first internet protocol (IP) address allocated to the first terminal, according to a first IP session, in response to a distance between the first terminal and a second gateway being equal to or less than a predetermined threshold, establishing a second IP session with the second gateway while the first IP session is set in the first terminal, receiving, from a second terminal, a first IP session-release message about the first IP session via the second gateway by using a second IP address according to the second IP session, when data from the first terminal is received by the second terminal according to the first IP session, and in response to the first IP session-release message being received from the second gateway, releasing the first IP session with the first gateway.

Abstract: The present disclosure relates to a communication method and a 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 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 of a communication apparatus includes determining an acknowledgement (ACK) transmission frequency for each flow, based on a state of a transmission control protocol (TCP) transmitter, identifying whether uplink resources are insufficient, selecting a flow for adjustment of the ACK transmission frequency when the uplink resources are insufficient, and adjusting the ACK transmission frequency of the selected flow.
