Summary:A method comprises receiving a handover request from a source BS, the handover request comprising a request for a handover of a UE involved in at least two QoS flows using a first MRB with the source BS, wherein the apparatus is using at least a second MRB for other UEs; starting to buffer packets for the UE; receiving a subsequent message comprising, for each of the at least two QoS flows, a CN SN of a first packet not transmitted by the source BS for that QoS flow; identifying a second packet with the highest protocol entity SN according to a protocol entity transmission order of the second MRB among packets which the source BS has delivered to the UE using the first MRB and the apparatus has transmitted to the other UEs using the second MRB; and transmitting a message configuring the UE to use the second MRB.
