METHOD FOR HANDOVER MANAGEMENT WITHIN HETEROGENEOUS NETWORKS

摘要

A base station (1) controlling a first cell and providing a user plane (3) and a control plane (4) to a user equipment (2), said first cell overlaying a second cell under control of a second base station (5) connected to the said base station by means of a 3GPP X2 interface, said second cell (5) being a potential handover target of the user equipment (2), the said user plane (3) including a packet data convergence protocol layer, a radio link control layer, a medium access control layer, and a physical layer, wherein the said base station (1) is configured to switch, over the 3GPP X2 interface, the medium access control layer, and the physical layer of the user plane (3) to the said second base station so that the user plane traffic is delivered to the user equipment (2) through the medium access control layer, and the physical layer of the of the said second base station.
