Abstract: The technology of this application relates to a method including, when a user equipment (UE) determines that a preset condition is met, the UE sends a session release request message or a session modification request message to a network device. The session release request message is used to request to release a first PDU session, the session modification request message is used to request to release a first quality of service (QoS) flow, and the first PDU session is one of existing PDU sessions in the UE. The preset condition includes at least one of: a quantity of existing PDU sessions in the UE reaching a first threshold; a quantity of data radio bearers (DRB)s associated with the existing PDU session in the UE reaching a second threshold; and a quantity of quality of service flows associated with the existing PDU session in the UE reaching a third threshold.

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.
