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: The present patent application discloses a handover method, a base station, and a terminal device. The handover method includes: sending, by a source base station, a handover request to a target base station, where the handover request includes information about a first service of a terminal device; receiving, by the source base station, a handover response sent by the target base station, where if the first service is supported by the target base station, the handover response includes information about a handover instruction for the first service, and the handover instruction is used to instruct the terminal device to hand over the first service from the source base station to the target base station; and sending, by the source base station, a handover response to the terminal device.

Abstract: A remote interference management method and an apparatus are provided. The method includes: A first network device receives a reference signal (RS) sent by a second network device, where the RS is used to indicate that the second network device is subject to remote interference. The first network device determines first auxiliary information, and sends the first auxiliary information to the second network device. The first auxiliary information includes at least one of the following information: frequency domain information of a downlink transmission resource of the first network device, time domain information of the downlink transmission resource of the first network device, or beam information of downlink transmission of the first network device.

Abstract: Example communication methods and apparatus are described. One example method includes sending a handover request message to a target base station, where the handover request message is used to instruct to hand over a first session of a terminal device from the source base station to the target base station. The handover request message includes first information. The first information includes information about at least one quality of service (QoS) flow in the first session. The first session is a session corresponding to the terminal device. The source base station receives a handover request response message from the target base station, where the handover request response message includes second information. The second information is used to indicate that the target base station accepts a first QoS flow in the first session, and the at least one QoS flow includes the first QoS flow.
