Abstract

Embodiments of the disclosure provide methods and apparatuses for handover in a heterogeneous network. According to the method, a candidate radio connectivity mode for use after handover from a source BS to a first target BS and/or a second target BS is determined; a first handover related message which comprises the candidate radio connectivity mode is sent to the source BS; and in response to receiving a second handover related message, the first target BS and/or the second target BS may be accessed, wherein the source BS is not associated with the first target BS, and wherein the first target BS is a LPN and is associated with the second target BS.
