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.
The present invention provides a method of a base station for supporting an inter-system handover from an evolved packet system (EPS) system to a 5th generation (5G) system. The method comprises receiving, from an access and mobility management function (AMF), a handover request message including E-UTRAN radio access bearer (E-RAB) information and quality of service (Qos) flow information, identifying whether a protocol data unit (PDU) session is accepted or not, determining whether a data forwarding for at least one Qos flow associated with the PDU session is accepted or not based on the E-RAB information and the Qos flow information in case that the PDU session is accepted and transmitting, to the AMF, a handover request acknowledgement message including information on the at least one Qos flow based on the determination. The method solves the data forwarding problem during the movement of a UE between an LTE system and a 5G system, so that the loss of data is avoided and the continuity of services is ensured.-

Abstract: A method for data forwarding in a small cell system comprises: sending by a master base station (MeNB) to a target secondary base station (SeNB) information of a source SeNB or a source SeNB cell where a user equipment (UE) is located; determining by the target SeNB whether a direct data forwarding is feasible; notifying, by the target SeNB, the MeNB whether the direct data forwarding is feasible; and determining by the MeNB whether it is a direct data forwarding or an indirect data forwarding. The method for data forwarding provided in the present application may support both the direct data forwarding and the indirect data forwarding based on actual situation of the network, reduce data loss and failure of data forwarding, and improve the efficiency of data forwarding.

Abstract: A method for supporting indication of a failure event to a source access system is provided. The method includes notifying, by the source access system, information of a source cell to a target access system, routing, by the target access system, a message to the base station or the base station controller of the source access through a core network by use of the information of the source cell received from the source access system when the target access system needs to transmit a message to the source access system. By use of the method provided by the present disclosure, a problem of mobility robustness optimization (MRO) among different radio access technology (RAT) may be notified to the source access system, so as to avoid impact for a terminal, reduce operator configuration.
