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.

Abstract: A link failure report transmission method and apparatus are provided. When a link between a terminal and a first radio access network device fails, and a master radio access network device of the first radio access network device is handed over, the terminal sends a first link failure report to a second radio access network device, so that the second radio access network device forwards the first link failure report to a third radio access network device, and the third radio access network device sends the first link failure report to the first radio access network device. In this way, the first radio access network device can perform parameter adjustment based on the first link failure report.

Abstract: This application provides a wireless connection control method relating to a base station system including a centralized unit and a distributed unit, wherein the centralized unit communicates with the distributed unit, and the distributed unit communicates with a terminal through an air interface. The method includes: first receiving, by the distributed unit, a first message sent by the terminal, where the first message is used to request to establish an air interface control plane connection for the terminal; then sending, by the distributed unit, the first message to the centralized unit; and then receiving, by the distributed unit, a second message sent by the centralized unit, where the second message is used to instruct to establish the air interface control plane connection between the terminal and the distributed unit. The method may implement wireless connection control in a 5G system when functions of a base station are separated.
