摘要： A data processing method and a related device are provided. In the data processing method, when a first device switches from a second device to a third device, the second device determines data receiving status information of the first device (101); the second device reports the data receiving status information of the first device to a fourth device (102); and the fourth device receives the data receiving status information and sends data to the first device based on the data receiving status information (103). The data receiving status information is used to indicate information about data that has been received by the second device but has not been acknowledged as received by the first device, in data sent by the fourth device to the first device through the second device. The fourth device is connected to a core network device, and the second device and the third device are respectively connected to the core network device by the fourth device. It can be learned that the second device reports the data receiving status information before the first device performs switching. Therefore, a loss of the data that has been received by the second device but has not been acknowledged as received by the first device can be avoided.
