Abstract: A terminal device obtains a cell change cause indication. The cell change cause indication indicates that a first cell change of the terminal device from a source cell to a first target cell or a second cell change of the terminal device from the first target cell to a second target cell is associated with a communication service of the terminal device. The first target cell uses a first radio access technology, and the source cell and the second target cell use a second radio access technology different from the first radio access technology. The terminal device sends the cell change cause indication to a second target access network device that provides the second target cell.

Abstract: A data transmission method, an apparatus, and a computer storage medium are provided. A first routing node receives downlink data of a terminal device. The first routing node sends a downlink paging request to a core network device, where the downlink paging request is used to indicate the core network device to search for a second access network device corresponding to a current location of the terminal device. The first routing node receives second routing information from a routing management node, where the second routing information is determined by the routing management node based on a routing information update request from the second access network device. The first routing node sends the downlink data to the terminal device via the second access network device based on the second routing information.

Abstract: Example measurement methods and apparatus are described. One example method includes obtaining a timer by a terminal device. The terminal device obtains two or more measurement configurations, where each of two or more measurement configurations includes a validity area and a measurement frequency corresponding to the validity area, and the validity area includes one or more cells. The terminal device measures, based on the measurement configuration, a measurement frequency corresponding to a validity area that matches a cell on which the terminal device camps, where the terminal device is in an idle state or in an inactive state, and the timer is not stopped and has not expired.

Abstract: The disclosure provides communication methods and apparatuses. One example method including a first access network device sends a first message to a terminal device and a second message to a core network device. The first message is used to indicate the terminal device to enter an inactive state. The second message carries context information and a first security verification parameter of the terminal device, and the first security verification parameter is used to perform security verification on the terminal device. The first access network device receives a third message from a second access network device, where the third message is used to request the context information of the terminal device. The first access network device sends a fourth message to the second access network device, where the fourth message is used to indicate the first access network device not to provide the second access network device with the context information.

Abstract: Embodiments of this application provide a communication method, a communications apparatus, and a storage medium. The communication method includes: sending, by a new master network device, a request to an original master network device, to request context information of a terminal device on the original master network device and an original secondary network device; and receiving the context information of the terminal device on the original master network device and the original secondary network device from the original master network device. This application can effectively simplify implementation steps of resuming a multi-connectivity mode by the terminal device, reduce signaling procedures, and shorten a delay, thereby improving network transmission efficiency.
