Assignee: DATANG MOBILE COMMUNICATIONS EQUIPMENT CO., LTD.
Field: Digital communication (Electrical engineering)
Classification: CPC H | IPC H

Claim 9:
10. A mobility management method, applied to a terminal, wherein the mobility management method comprises:
reporting a measurement report to a current cell of a non-ground mobile communication network according to a configuration message, in the condition that the terminal is communicated with the non-ground mobile communication network, wherein the configuration message is sent to the terminal and is used for the terminal to carry out the terminal position information measurement, and the configuration message comprises the terminal position information, or terminal moving information and the terminal position information, and a reporting occasion of the configuration message;
the terminal moving information comprises moving speed, a moving direction and a type of the terminal, and the reporting occasion is a moment in the condition that a moving state of the terminal is rapidly changed or a reporting period; and
the measurement report at least comprises signal strength of a target cell or terminal position information, and the current cell is a serving cell that provides services to the terminal at present in an NG-RAN (Next Generation-Radio Access Network) of the non-ground mobile communication network; and
carrying out handover from the current cell of the non-ground mobile communication network to the target cell of the ground mobile network, according to a handover message, after the handover message of the current cell is received;
wherein the handover message is sent by the NG-RAN when a specified moment within a time range in which the terminal reaches an area co-covered by the current cell and the target cell is reached, and the time range is predicted by the NG-RAN according to the terminal position information in the measurement report and a moving speed and positioning information of the NG-RAN, or according to the terminal position information and the terminal moving information as well as the moving speed and positioning information of the NG-RAN,
wherein the predicting comprises:
within a specified time range, predicting, according to the moving speed and positioning information of the NG-RAN, a moving track, of a cell corresponding to each beam in the NG-RAN of the non-ground mobile communication network, on the ground;
within the specified time range, predicting a moving track of the terminal according to the terminal position information or the terminal position information and the terminal moving information; and
determining, according to the moving track of the cell corresponding to each beam in the NG-RAN of the non-ground mobile communication network, on the ground, and the moving track of the terminal, the time range in which the terminal reaches the area co-covered by the current cell and the target cell.
