Abstract: Embodiments can provide an inter-cell handover method and a controller to shorten a handover delay. For achieving such, a target cell can be determined by a first controller of a source cell. The first controller can send a pre-handover request to a second controller, which may be a controller of the target cell. The pre-handover request can be configured for instructing the second controller to allocate a first resource for a cell handover to a terminal device. The first controller can send a handover command to the terminal device when the first controller determines that the terminal device meets a handover condition. The handover command can be configured for instructing the terminal device to be handed over from the source cell to the target cell based on the first resource.

Abstract: Embodiments of the application provide a method and an apparatus for managing a network slice. A first update request message sent by a second network device is received by a first network device. The first update request message carries network slice requirement information. The network slice requirement information is used to indicate that a network resource of a first network slice needs to be updated to a first network resource. A second network resource that can be actually provided for the first network slice is determined by the first network device based on the first update request message. An update acknowledgement message is sent by the first network device to the second network device. The update acknowledgement message is used to instruct to update the network resource of the first network slice based on the second network resource.

Abstract: Methods for determining a tracking area is provided. One example method includes sending, by a terminal device, indication information to a core network device, where the indication information is used to indicate a position of the terminal device; and receiving, by the terminal device, first TA information from the core network device, where the first TA information includes a TA corresponding to the position of the terminal device, and the TA is determined based on the position of the terminal device. In the foregoing technical solution, the tracking area of the terminal device is managed based on the position of the terminal device, and the tracking area of the terminal device can be managed without depending on a cell ID change of the terminal device.
