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 and equipment for handover are provided. The method includes informing, by a source base station, a source core network whether a direct data forwarding path is available, determining, by the source core network, whether to use direct data forwarding or indirect data forwarding, informing, by the source core network, a target core network of information of direct data forwarding, indirect data forwarding or data forwarding being not possible, informing, by the target core network, a target base station of the information of direct data forwarding, indirect data forwarding or data forwarding being not possible, and allocating, by the target base station, tunnel information for data forwarding.

Abstract: The present disclosure provides a method and device for configuration of minimization of drive tests, in which a first node sends MDT status information to a second node; and the second node decides whether it is possible to configure a management-based logged MDT measurement for a UE. It is avoided that the MDT configuration information that is currently still valid is erroneously overwritten when the network reconfigures the MDT for the UE.
