摘要： A user equipment (UE), a source base station, a target base station, and handover methods for seamless and radio resource efficient UE MBS mobility are provided. The handover method performed by the UE includes transmitting, to a source base station, a handover control information and/or a measurement report containing an indication of UE interest on an MBS service reception, receiving from the source base station, a handover command, starting receiving an MBS data from the source base station via the associated DRB or PTP MRB/DRB PDCP and/or RLC leg until sending a handover complete message to the source base station or the target base station, stopping the reception of MBS service data via the associated DRB or the PTP MRB/DRB leg, and starting to receive the MBS service data via an existing configured MRB or PTM MRB PDCP and/or RLC leg.
