Abstract: A data transmission method and a related device and system to improve data transmission efficiency are described. In at least some embodiments, a first message sent by a second base station is received by a first base station. The first message is used to indicate that the second base station needs to transmit data. A second message is sent to the second base station by the first base station. The second message carries at least one address, and the address is associated with the data.

Abstract: Example communication methods and apparatus are described. One example method includes sending a first handover request by a source base station to a core network device, where the first handover request is used to request to hand over a current session of a terminal from the source base station to any one of at least one base station, and the first handover request includes information about the at least one base station. The source base station receives a first handover response message from the core network device, where the first handover response message includes indication information, and the indication information is used to indicate whether a first base station of the at least one base station supports a network slice corresponding to the current session of the terminal device.

Abstract: Example communication methods and an access network device are described. One example method includes sending a first message to a second access network device by a first access network device, where the first message carries a quality of service (QoS) flow identification (QFI) for a split bearer corresponding to the first access network device and a QoS parameter corresponding to the QFI. The second access network device receives the first message from the first access network device, where the first message carries the QFI for the split bearer corresponding to the first access network device and the QoS parameter corresponding to the QFI. The second access network device sends a second message to the first access network device, where the second message is a response to the first message. The embodiments of this application are used to implement QoS control.

Abstract: A data transmission method and a network device are provided. The method can include: determining, by a first network device, that a terminal device enters an RRC inactive state; sending, by the first network device, a first message to a second network device, where the first message is used to configure the second network device, so that the second network device transmits data for the terminal device in the RRC inactive state; and receiving, by the first network device, an acknowledgment message the first message and sent by the second network device. The second network device can transmit data of the terminal device to the first network device to enable the first network device to send the data to a core network, without having to establish a path between the second network device and the core network for the second network device to send the data to the core network.
