    Abstract: The present disclosure relates to communication methods and network devices. In one example method, a first network device receives a first message sent by a second network device, where the first message is used to notify whether the first network device configures a default data radio bearer (DRB), and the first network device and the second network device are network devices that provide a multi-connectivity service for a same terminal device. The first network device determines, based on the first message, whether to configure the default DRB.

    Abstract: A communication method, a related device, and a system. The method includes: a first network device receives first information from a terminal device, where the first information includes a first delay and a second delay, the first delay is a delay of the terminal device on a first path, the second delay is a delay of the terminal device on a second path, and data packets transmitted on the first path and the second path belong to a first data radio bearer (DRB). The first network device determines an uplink delay of the first DRB based on the first information, a fourth delay, and a fifth delay, where the fourth delay is a network-side delay on the first path, and the fifth delay is a network-side delay on the second path.

    Abstract: This application provides a minimization of drive tests (MDT) measurement solution, which may be used to implement an MDT measurement of a network device with an architecture in which a central unit (CU) entity and a distributed unit (DU) entity are separated. A centralized unit control plane (CU-CP) determines configuration information, and sends the configuration information to a centralized unit user plane (CU-UP) of the network device. The configuration information is used to perform an MDT measurement on a measurement object. The solution in this application may be applied to a communications system, for example, may be applied to a 5th generation (5G) network.

    Abstract: A data transmission method and apparatus are disclosed. The method includes: determining, by a source base station of a terminal in a handover process, first data and a radio air interface protocol sequence number of a data unit used to carry the first data, where the first data includes data that is not acknowledged by a terminal for correct reception during data transmission between the source base station and the terminal. The method further includes sending, by the source base station, the first data and the radio air interface protocol sequence number to a target base station; where the core network connected to the target base station is different from the core network connected to the source base station.
