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 for supporting handover and a corresponding base station and network node for performing the method is provided. The method includes forwarding data to a target base station, receiving a first end marker packet from a core network, and transmitting, for a quality of service, quality of service (QoS), flow for which the data forwarding has been completed, a second end marker packet to the target base station, the end marker packet containing a QoS flow identity (QFI). The methods of embodiments of the disclosure may reduce the packet transmission delay and improve the user experience.

Abstract: The present disclosure provides a method, a system, and an apparatus for transmitting group communication service data. In the present disclosure, the LTE uses a multimedia broadcast and multicast service (MBMS) to transmit group communication system enabler (GCSE) service data, a multi-cell/multicast coordination entity (MCE) knows whether a multimedia broadcast single frequency network (MBSFN) transmission mode or a single cell multicast transmission mode is used to transmit the GCSE service data. Whether the MBSFN transmission mode or the single cell multicast transmission mode is used to transmit the GCSE service data is determined based on UE capability information and UE location information. When the single cell multicast transmission mode is used, the MCE instructs an eNodeB (eNB) to use the single cell multicast transmission mode to transmit the GCSE service data. The present disclosure saves LTE air interface resources.
