Abstract: A communication method and a communications apparatus, where the method may include: selecting or re-selecting, by a terminal device, from a first cell to a second cell through cell selection or re-selection, where radio access technologies of the first cell and the second cell are different, and where the terminal device is in an inactive mode in the first cell; re-selecting, by the terminal device, to the second cell through cell re-selection; and initiating, by the terminal device, a registration procedure after completing the cell re-selection. When the terminal device in inactive mode performs cell re-selection based on different radio technologies, the terminal device initiates the registration procedure or a service request procedure, for NAS signaling connection recovery. When the terminal device changes a radio access technology, a network device can update information.

Abstract: This application provides a communication method and a communication apparatus. The method includes: A terminal device receives first information, where the first information includes first indication information and/or second configuration information, the first indication information is used to indicate that the second configuration information is the same as or different from first configuration information, the second configuration information is configuration information corresponding to a first service in a second cell, the first configuration information is configuration information corresponding to the first service in a first cell, and the second cell is a neighboring cell of the first cell; and the terminal device receives, based on the first information, data of the first service provided by the second cell. In this way, a service delay can be reduced and service continuity can be improved.

Abstract: A data transmission method, a node, and a system, the method including receiving, by a forwarding node, a data packet, where a label stack of the data packet comprises a path identifier (path-ID), where the path-ID is an identifier of a constrained path, and where the constrained path is a path that consists of at least two nodes arranged in a specific order, determining, by the forwarding node, that the forwarding node is a node on the constrained path, selecting, by the forwarding node, a target label/target address from a local available label block/address block according to the path-ID and according to a preset rule, where the label block/address block comprises at least one label/address, searching for, by the forwarding node, a corresponding target interface according to the target label/target address, and forwarding, by the forwarding node, the data packet through the target interface.
