Abstract: User equipment provides, to a network device, reference paging information generated according to a moving speed of the user equipment. The reference paging information is used by the network device to determine a paging area for sending a paging message. The network device receives the reference paging information generated by the user equipment according to the moving speed of the user equipment. The network device determines, according to the reference paging information, a paging area for sending a paging message to the user equipment. The network device sends, in the paging area, the paging message to the user equipment. The network device can determine the paging area according to the reference paging information, so that a paging resource waste in a paging process is reduced, relatively accurate paging is implemented, overheads of inter-network interfaces and air interfaces are greatly reduced, and system efficiency and stability are improved.

Abstract: Embodiments of the present invention provide a communication method and a communications device. The method includes: sending, by a base station, a message including measurement configuration to UE, where the measurement configuration is used to request the UE to report a cell global identifier of a cell; obtaining, by the base station, a measurement report reported by the UE, where the measurement report corresponds to the measurement configuration and includes the cell global identifier of the cell and band information of the cell; and performing, by the base station, cell handover based on the band information and the cell global identifier of the cell. By means of the present invention, the base station obtains complete and accurate band information of the cell, so that the base station can perform accurate handover decision, thereby avoiding handover failure.

Abstract: The present invention discloses a base station, a terminal, and a handover method. The handover method includes: sending an indication message by a base station, wherein the indication message is used to instruct the terminal to further establish a connection to the base station through a second channel in a case in which the terminal maintains a connection to the base station through a first channel; receiving an access message by the base station through the first channel, wherein the access message indicates that the terminal has established the connection to the base station through the second channel; sending a handover command by the base station, wherein the handover command instructs the terminal to switch the communication with the base station from the first channel to the second channel; and switching, by the base station, communication with the terminal from the first channel to the second channel.
