    Abstract: The present invention provides a handover method, a base station and a system. The handoff method comprises: a low-power base station monitors an uplink signal which is sent by a user equipment served by a neighbor base station, and obtains signal measurement information of the uplink signal and characteristic information of the uplink signal; the low-power base station sends the signal measurement information of the uplink signal and the characteristic information of the uplink signal to at least one macro base station which covers the low-power base station, so that the macro base station, according to the signal measurement information, determines whether the user equipment to which the characteristic information corresponds is unloaded to the low-power base station.

    Abstract: A key management method and a communication apparatus is disclosed. The method includes receiving, by a first radio access network (RAN) device, a key parameter and an identifier of a target terminal device sent by a first terminal device, performing at least one of encryption or decryption on transmission data related to communication between the first terminal device and the target terminal device based on the key parameter, and sending, by the first RAN device, the key parameter and an identifier of the first terminal device to the target terminal device.

    Abstract: The present disclosure relates to connection establishment methods and apparatus. In one example method, a central unit (CU) function entity receives a first connection establishment request of a master device, where the first connection establishment request includes at least first identification information of a terminal, identification information of a first data radio bearer (DRB), identification information of a target cell, and interface information of the master device. The CU function entity sends a second connection establishment request to a distributed unit (DU) function entity to request the DU function entity to establish a connection to the master device, where the second connection establishment request includes at least second identification information of the terminal, the identification information of the first DRB, and the interface information of the master device.

    Abstract: A method includes: acquiring, by a second base station, time-frequency position information corresponding to cell key information of a first base station, where the time-frequency position information is used for determining a time-frequency position that is corresponding to the cell key information of the first base station and that is on a shared time-frequency resource, and the cell key information includes at least one of a cell-specific reference signal (CRS), a channel state indication-reference signal (CSI-RS), a physical broadcast channel (PBCH), and a synchronization signal. The method also includes performing, by the second base station, interference coordination on the first base station.
