Abstract: Example communication methods and apparatus are described. One example method includes determining, by a terminal device, that a connection failure occurs between the terminal device and a first cell, where the first cell is a cell of a first network device. The terminal device determines signal quality of a second cell of a second network device, where both the first network device and the second network device provide communication services for the terminal device. If the signal quality of the second cell is greater than or equal to a first preset threshold, the terminal device performs a connection recovery process between the terminal device and the first cell by using the second cell.

Abstract: This application provides a communication method and apparatus. The method includes: a terminal device receives conditional handover configuration information from a first network device, where the configuration information is used to configure a trigger condition of a conditional handover, and the first network device is a network device to which a serving cell currently accessed by the terminal device belongs. The terminal device determines a first target cell based on the conditional handover configuration information, where the first target cell is a cell in at least one candidate target cell that satisfies the trigger condition.

Abstract: A communication method, apparatus, and system are disclosed, to provide a mechanism of mobility, of a terminal device that supports private networks, between the private networks. The method includes: a first access network device determines, based on a first list, a target cell that belongs to a target first network, where the first list includes an identity of at least one first network to which a terminal device subscribes. The first access network device sends a first message to a second access network device that serves the target cell, the first message carries a second list, the second list is used to enable the second access network device to determine the identity of the at least one first network to which the terminal device subscribes.

Abstract: Embodiments of this application provide a data transmission method and device. The method includes: obtaining, by a first access network device, a first message from a second access network device, where the first message requests context information of a terminal device; and sending, by the first access network device, a data packet to the second access network device. The first access network device is a corresponding access network device of the terminal device before the re-establishment procedure, and the second access network device is a corresponding access network device when the terminal device initiates the re-establishment procedure.
