HANDOVER IN HETEROGENEOUS COMMUNICATION NETWORKS

摘要

Embodiments of the present invention provide 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. Embodiments of the present invention can realize that the macro base station unloads the user equipment to which the characteristic information corresponds to the low-power base station based on the signal measurement information and the characteristic information sent by the low-power base station, thereby the problem occurred in a HetNet network, which is the strong interference at short range on an uplink and a downlink, can be alleviated effectively.
