Abstract: Embodiments of this application provide a transmission path switching method and apparatus. When a transmission path is switched, a currently used data transmission path is not directly switched from a first transmission path to a second transmission path after the second transmission path is configured, but after it is further determined that a first condition is met, the currently used data transmission path is switched from the first transmission path to the second transmission path, to avoid data interruption in a process of switching a data transmission path of an application from the first transmission path to the second transmission path. This improves use smoothness of the application.

Abstract: A session management method by a terminal in which a network initiates a session deactivation procedure to deactivate one or more sessions of a terminal. After the terminal in an inactive mode establishes an RRC connection to a new second base station, the second base station indicates, through RRC connection reconfiguration, the terminal to delete related information of the to-be-deactivated session, or the second base station uses an RRC connection resume response message to carry an identifier of the one or more to-be-deactivated sessions, and the terminal deletes session-related information corresponding to the identifier of the one or more to-be-deactivated sessions. In this way, the terminal is enabled to process the related information of the to-be-deactivated session in a timely manner.

Abstract: This application discloses a network access method and device. The method includes: receiving, by a first management entity, a first request message sent by a first terminal, where the first request message includes at least a first identifier of a second terminal; determining, by the first management entity based on a first condition, whether the second terminal can access a network by using the first terminal, where the first condition includes at least that the first identifier of the second terminal belongs to a list of at least one terminal having a trust relationship with the first terminal, and the list includes at least a first identifier of the at least one terminal having the trust relationship with the first terminal; and when the first condition is satisfied, sending, by the first management entity, a second message to the second terminal, where the second message is used to indicate that the second terminal can access the network by using the first terminal. Legality of access by a wearable device to a network by using a user terminal can be authenticated by using the method and device in this application.
