    摘要： Embodiments of this application provide a data processing method and a related device, to effectively ensure that a terminal in the Narrowband Internet of Things can completely receive, after accessing a target base station, downlink data that is not completely received before handover or reselection, in other words, to effectively ensure that the downlink data of the terminal is not lost, thereby ensuring mobility of the terminal in connected mode. Technical solutions provided in the embodiments of this application are as follows: A core network device obtains a first indication message, where the first indication message is used to indicate that a terminal completes a cell change or a cell reselection. The core network device sends downlink data to a target base station, where the target base station is a base station to which the terminal is connected after completing the cell change or the cell reselection.

    摘要： This application provides a communication method and a communication apparatus. The method includes: A first device determines first indication information, where the first indication information indicates at least one second device to access the first device when access needs to be performed; and the first device sends the first indication information. In this way, a reader/writer may provide an access opportunity for a tag device that needs to perform access, to improve system efficiency and reduce a missed reading rate.
