Abstract: Embodiments of this application provide a data transmission method and apparatus. The method includes: receiving data sent by a terminal in an inactive state, where the data includes to-be-sent data sent by the terminal and identification information of the terminal; determining an anchor base station of the terminal based on the identification information; and sending the data to the anchor base station, so that the anchor base station sends the data to a core-network device. The uplink data of the terminal is forwarded to the anchor base station by using a serving base station and through an interaction between the anchor base station and the serving base station that currently provides an air interface resource for the terminal, and is then transmitted to a core network.

Abstract: Embodiments of this application disclose a communication method and a communications apparatus. A source base station instructs a terminal to hand over from the source base station to a target base station, and sends, to the terminal, configuration information of a second connection required for communication between the terminal and the target base station. The terminal maintains a first connection for communication with the source base station, and establishes the second connection for communication with the target base station based on the configuration information of the second connection. The solutions in the embodiments of this application reduces latency in a handover process.

Abstract: The embodiments of this application provide a communication method and an apparatus, and relate to the field of communications technologies, to successfully report MCG link failure information. The method includes: When a terminal device sends a first data unit to a first access network device via an MCG split bearer, the terminal device determines that an MCG link failure occurs. In addition, the terminal device sends a second data unit to a second access network device via an SCG split bearer, so that the second access network device sends the second data unit to the first access network device, where the second data unit includes information used to indicate the MCG link failure.
