Abstract
Embodiments of the present disclosure disclose a base station handover method in a heterogeneous network, and a base station. The method includes: after receiving a handover request message of a first base station, a target base station executes an admission control, and judges whether a connection of UE at a second base station is reserved for the UE after an access of the UE; if the connection is reserved, the target base station sends an assistance request message to the second base station to request the second base station to assist the target base station to provide a dual connectivity service for the UE, and replies a handover request acknowledgment message to the first base station after a reply message of the second base station is obtained.
