Abstract: A method and apparatus are provided that controls the handover between DUs in an eNB including a CU and a DU. The method and system fuses 5G communication systems with IoT technology to transmission data at a high rate after 4G systems. The communication method and system is applied to intelligent services, based on 5G communication technology and IoT related technology. The method includes transmitting, to a source DU of the base station, a first message related to a handover; receiving, from the source DU, a second message for downlink data delivery information related to a PDU transmitted from the source DU to a terminal; receiving, from a target DU of the base station, a third message based on a random access procedure of the terminal toward the target DU; and transmitting, to the target DU, downlink data based on the downlink data delivery information after receiving the third message.

Abstract: The present disclosure relates to a 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). The present disclosure relates to a communication technique for convergence of a 5G communication system for supporting a higher data transmission rate beyond a 4G system with an IoT technology, and a system therefor. The present disclosure may be applied to 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, etc.) on the basis of a 5G communication technology and an IoT-related technology.

Abstract: A method and apparatus is provided that controls the handover between distributed units (DUs) (inter-DU handover) in an eNB including a central unit (CU) and a DU. The method and system fuses 5G communication systems with IoT technology to transmission data at a high rate after 4G systems. The communication method and system is applied to intelligent services, based on 5G communication technology and IoT related technology, for example, smart homes, smart buildings, smart cities, smart cars or connected cars, health care, digital education, retail business, security, safety-related services, etc. The method includes transmitting, to a source DU of the base station, a first message instructing a handover; receiving, from the source DU, a second message including feedback information related to a packet data unit (PDU) transmitted from the source DU to a terminal; receiving, from a target DU of the base station, a third message including information on a random access of the terminal; and transmitting, to the target DU, downlink data, based on the second message, in response to the third message.

Abstract: A method and an apparatus for controlling user equipment (UE) context between a plurality of nodes are provided. The method includes transmitting, to a second node, a first message to request a user equipment (UE) context update, receiving, from the second node, a second message indicative of a completion of the UE context update or a third message indicative of a failure of the UE context update in response to the transmission of the first message, and determining whether to retransmit the first message to the second node based on the reception of the second message or the third message. The procedure of the UE context update may be initiated by the transmission of a message to request an operation of the UE context update to be performed between a UE and a third node from the second node to the third node.

Abstract: The present disclosure relates to a 5th generation (5G) or pre-5G communication system for supporting a higher data transmission rate than a 4th generation (4G) communication system such as long term evolution (LTE). The present disclosure is to manage connections in a wireless communication system, and an operating method of a distributed unit of a base station may include receiving a first control message processed by a central unit from a terminal, transmitting to the central unit the first control message modified to indicate rejection of a procedure requested by the first control message, and in response to the modified first control message, receiving a second control message indicating the procedure rejection.
