Multi-cell communication method and system of a mobile terminal, a micro base station, and a macro base station

摘要

Communication methods of a macro base station which collects position information about a mobile micro base station and that is served by the macro base station, predicts a channel between the macro base station and the micro base station, and performs a handover between the macro base station and the micro base station based on a state of the predicted channel is provided.

1. A communication method of a macro base station, the communication method comprising:
receiving a handover request message of a terminal, through a control channel between the terminal and the macro base station; in response to the handover request message,
in response to a target base station of a handover being the macro base station, establishing a data channel between the terminal and the macro base station, andin response to the target base station of the handover being a micro base station, transmitting data to the micro base station in a cell coverage of the macro base station; and continuously maintaining the control channel between the terminal and the macro base station after the handover is completed, regardless of whether the target base station of the handover is the micro base station or the macro base station, regardless of the terminal requesting a handover to be performed from the micro base station to another micro base station, and regardless of whether or not the terminal requests the handover to be performed from the micro base station to the other micro base station.
